10-bit and HDR Video Encoding Support:
OBS now supports 10-bit and HDR, courtesy of rcdrone, YouTube, and Luxoft. New color format and color space settings have been added in the advanced settings to allow this.
Important notes about HDR and 10-bit:
HDR and 10-bit can only be encoded with AV1 and HEVC encoders.
10-bit HEVC encoding requires NVIDIA 10-series, AMD 5000 series, or newer GPU. Intel QuickSync and Apple VT are not yet supported.
The recommended settings for HDR are Color Format P010 and Color Space Rec. 2100 PQ.
If you wish to encode 10-bit SDR, you can use Color Format P010 with an SDR color space (e.g. Rec. 709, Rec. 601). However, AV1 or HEVC will still be required.
HDR streaming is currently only supported via YouTube's HLS service via an HEVC encoder.
When composing in SDR, games that operate in HDR can now be properly tonemapped to SDR.
Video capture devices can be used to capture and stream in HDR if the device supports it (e.g. EVGA XR1 Pro, Elgato 4K60 Pro Mk.2, AverMedia Live Gamer 4K).
For a list of tested devices, see https://obsproject.com/kb/video-capture-devices-with-hdr-support
Certain filters will not function if a source is rendering with HDR:
Apply LUT, Chroma Key, Color Key, Image Mask/Blend, Luma Key, Sharpness
Mac/Linux support is limited. HDR preview does not work, and several inputs/encoders still need to be updated.
Updating to Qt 6:
As of May 2020, version 5 of the Qt user interface toolkit ceased public development and is no longer being updated. Since then, our need for a more up-to-date version has been increasing as time goes by. With version 28.0, we felt it was important for us to update our user interface toolkit to the latest version; not just to gain access to the latest features, but also for the latest bug fixes and improved support for newer operating systems and architectures such as Windows 11 and Apple Silicon. Unfortunately, this also means that certain plugins that depend on version 5 of Qt will no longer work when you upgrade to version 28.0 and will need to be updated.
During this beta period of OBS 28.0, many of those plugins which rely on Qt version 5 may not yet be updated yet, and we'll be working with third-party plugin developers in order to get them updated before the final release deploys.
Additionally, Qt 6 has dropped support for Windows 7 & 8, macOS 10.13 & 10.14, Ubuntu 18.04 and all 32-bit operating systems. As such, OBS will no longer be supported on these platforms.
For more details, please refer to our Discussion Post: Plan to Upgrade OBS Studio to Qt 6.
Native Apple Silicon Support:
With OBS 28, OBS now has native builds for Apple Silicon systems. This means that OBS will run more optimally and without x86 emulation. Unfortunately, an important caveat for this is that many third-party plugins may not yet be readily available for Apple users running native Apple Silicon builds. Users can still use x86 builds of OBS if they desire a wider selection of third-party plugins that are not yet available natively for Apple Silicon.
New Features and Additions:
Added a new, more optimal and up-to-date implementation of the AMD encoder on Windows [OvchinnikovDmitrii/Jim]

10-bit and HDR Video Encoding Support:
OBS now supports 10-bit and HDR, courtesy of rcdrone, YouTube, and Luxoft. New color format and color space settings have been added in the advanced settings to allow this.
Important notes about HDR and 10-bit:
HDR and 10-bit can only be encoded with AV1 and HEVC encoders.
The recommended settings for HDR are Color Format P010 and Color Space Rec. 2100 PQ.
If you wish to encode 10-bit SDR, you can use Color Format P010 with an SDR color space (e.g. Rec. 709, Rec. 601). However, AV1 or HEVC will still be required.
HDR streaming is currently only supported via YouTube's HLS service via an HEVC encoder.
When composing in SDR, games that operate in HDR can now be properly tonemapped to SDR.
Video capture devices can be used to capture and stream in HDR if the device supports it (e.g. EVGA XR1 Pro, Elgato 4K60 Pro Mk.2, AverMedia Live Gamer 4K).
Certain filters will not function if a source is rendering with HDR:
Apply LUT, Chroma Key, Color Key, Image Mask/Blend, Luma Key, Sharpness
Mac/Linux support is limited. HDR preview does not work, and several inputs/encoders still need to be updated.
Updating to Qt 6:
As of May 2020, version 5 of the Qt user interface toolkit ceased public development and is no longer being updated. Since then, our need for a more up-to-date version has been increasing as time goes by. With version 28.0, we felt it was important for us to update our user interface toolkit to the latest version; not just to gain access to the latest features, but also for the latest bug fixes and improved support for newer operating systems and architectures such as Windows 11 and Apple Silicon. Unfortunately, this also means that certain plugins that depend on version 5 of Qt will no longer work when you upgrade to version 28.0 and will need to be updated.
During this beta period of OBS 28.0, many of those plugins which rely on Qt version 5 may not yet be updated yet, and we'll be working with third-party plugin developers in order to get them updated before the final release deploys.
Additionally, Qt 6 has dropped support for Windows 7 & 8, macOS 10.13 & 10.14, Ubuntu 18.04 and all 32-bit operating systems. As such, OBS will no longer be supported on these platforms.
For more details, please refer to our Discussion Post: Plan to Upgrade OBS Studio to Qt 6.
Native Apple Silicon Support:
With OBS 28, OBS now has native builds for Apple Silicon systems. This means that OBS will run more optimally and without x86 emulation. Unfortunately, an important caveat for this is that many third-party plugins may not yet be readily available for Apple users running native Apple Silicon builds. Users can still use x86 builds of OBS if they desire a wider selection of third-party plugins that are not yet available natively for Apple Silicon.

New Features
Added the ability to capture Vulkan-based games with game capture. Big thanks to Ubisoft Montreal for submitting this feature! [Littlematth/jpark37/Jim]
Added a new capture method to window capture which allows capturing browsers, browser-based windows, and Microsoft Store (UWP) programs [jpark37]
By default, it will use "Automatic", which will use the normal method on most windows, and the new method on browsers, browser-based windows, and Microsoft Store (UWP) programs
The downside of the new method is that it can cause a bit of cursor lag, as well as a highlighted border around the captured window. The border itself does not get captured, however.
You can choose which capture method to use in window capture properties
Added advanced scene collection importing (on the menu bar, Scene Collection -> Import) which allows you to import from other common streaming programs [Dillon]
Added Media source hotkeys to allow control of playback (stop/pause/play/restart) [cg2121]
For now, these are just hotkeys. User interface for this is also planned for future updates
Added the ability to drag and drop URLs to create browser sources (after displaying a confirmation prompt to ensure it was by intention) [WizardCM]
Developers can add an embed to their web pages that let them pre-specify parameters that automatically get set in the source when it's dragged into OBS. See this link for more details: https://obsproject.com/tools/browser-drag-and-drop
Added T-bar to studio mode [cg2121]
Note that this will not work while using a Stinger transition or the "Cut" transition

Added an option to toggle looping to the scroll filter [Dillon]
Added a "Fade to Black" option for quick transitions in studio mode [cg2121]
Added string specifiers to the Filename Formatting option in advanced settings which allows you to specify certain settings such as resolution and FPS to recording filenames [exeldro]
Added a hotkey to reset the stats window/panel [cg2121]
Added help icons when an property has a tooltip associated with it [WizardCM]
Added monitor names in monitor selection context menus [WizardCM]
Video settings now shows aspect ratio of canvas and output resolutions [cg2121]
Changes/Tweaks:

The browser source now uses a monospace font for the custom CSS property [WizardCM]
Redesigned Decklink output UI by combining the start and stop buttons and highlighting them when the output is active. [cg2121]
Removed the older deprecated NVENC encoder in advanced output mode to prevent confusion. You will now only see "NVENC (new)" (which we will eventually rename back to just "NVENC"). Rescaling is now supported on it (automatically falls back to the older implementation internally)
Bug Fixes:

New in OBS Studio 23.2 (Jun 17, 2019)

New Features/Improvements:
Made a number of major internal improvements to the macOS browser source, eliminating many mac-related crashes that it would cause when browser sources were in use on macOS. This also fixes the issue of the program having an initial startup delay where the everything appeared blank. (Author note: I managed to get browser panels functioning, but they still have some issues, so service integration is still not yet available on macOS)
Added the ability to preview transitions in the properties of a transition via a new Preview button
Added an estimate to remaining available recording time according to available disk space
Added luma key video effect filter
Added the ability to set the exact desired dB volume value of sources in the advanced audio properties, replacing the percentage value

Added a hotkey to toggle the preview
Added the ability to output the preview rather than program to a decklink device when in studio mode
Added the ability to copy and paste filters to/from scenes in addition to sources
Added the ability to manually set the network buffer size to the Media source when used in URL mode
Added the top patrons list to the about dialog in the help menu
The sources list box in the bottom-center of the main window now displays a message when there are no sources in the current scene, making it easier for first-time users to understand that they need to add sources
Bug Fixes/Tweaks:
Fixed an issue on Linux where the program would not be able to capture some monitors
Fixed a bug where the "test bandwidth" option wouldn't reset properly until the program was restarted
Fixed a bug where the program would freeze up when an encoder error occurs in the middle of a recording or stream (it now shows an error and should now safely recover)
Fixed a bug where the selection lines of rotated items would incorrectly scale
Fixed a bug where audio would no longer work when certain types of audio devices are unplugged and plugged back in again
Fixed a bug where you could not press escape to cancel when renaming a scene
Fixed a bug where opacity on the mask/blend filter would not work under certain circumstances
Fixed a bug where fractional framerate recordings (59.94, 29.97) recorded with the new version of NVENC would have incorrect DTS timestamps in the recording file
Fixed an issue with VAAPI encoder on Linux where CBR would not always output at a constant bitrate
Fixed an issue where cookies would not properly be saved for browser panels (Twitch Chat/etc) when shutting down the program

Moved audio monitoring device from advanced settings to audio settings
Improved logging when recording errors occur
Added a warning popup message box to Twitch authentication if the account is not set up for two-factor authentication (which is now required to stream on Twitch)
Removed the 5 item limit when dragging and dropping files in to OBS
Buttons in the Hotkeys list are now icons rather than text
Changed all opacity spin boxes in filters to sliders
Changed the default size of the color source to the same size as the canvas
Made the Dark theme a bit more consistent across operating systems
Scene item group details are now included in the log file
The stats dock no longer updates when it's not visible
When first renaming a source or scene, the existing text is now automatically selected
The Dark theme has now been renamed to "Dark (Default)", and the "Default" theme has now been renamed to the "System" theme

New in OBS Studio 23.1 (Apr 7, 2019)

New Features/Improvements:
Added optional Twitch activity feed panel when account is connected to OBS (hidden by default, you can show it in the View -> Docks menu)
Added Restream.io account integration (account integration is currently only available on Windows)
Added option to select color range to Linux video device source
Added ability to copy and paste filters from the mixer
Added preview/program labels to studio mode

This fixes an issue where large image counts would cause increased CPU usage and rendering lag when transitioning images, or when switching scenes in some cases.
Removed the close buttons from primary docks (scenes, sources, transitions, mixer, controls). These docks can still be hidden, but now must be explicitly hidden with the view menu instead. This change does not apply to secondary docks, such as chat, stream information, or stats.
On Linux, the tray now uses icons from the system theme
Fixed a bug when upmixing from mono to stereo would cause the volume to be quieter
Fixed a bug where NVENC wouldn't show up for the NVIDIA Quadro P5000
Fixed another case where the last frame of an NVENC stream/recording could show up as the first frame in a subsequent stream/recording in the same running session
Fixed another case where output could be green for certain devices
Fixed a crash that could happen if you clicked settings too quickly after starting up with streaming account integration, or if you exit the program too quickly

Added batch remuxing support to the Remux Recordings dialog.
Added an option to automatically remux recordings to MP4 in Advanced settings.
Added a Decklink output tool to the tools menu. This allows you to output OBS to a Decklink device.
Added an optional Stats dock. This dock is disabled by default; you can enable this dock in the View menu -> Docks submenu.
Added multi-track audio support to FFmpeg output in advanced output settings.
Added an About dialog to the Help menu.
Added a filter (search) option to the Hotkeys section of the settings window.
Added a fourth Mic/Auxiliary audio option in Audio settings.
Added stereo balancing (panning) to the Advanced Audio Properties dialog.
Added an option to change the OBS base/output resolution to the size of a source in the right-click context menu of the source. Only works when no outputs are active.
Added a "deactivate when not showing" option to the Decklink source.
Added an Invert Polarity audio filter.
Added an F2 shortcut to rename sources or scenes when selected.
Added VLC source support to the Instant Replay script.
Added a "What's New" dialog that may pop up on startup in the case of announcements or important news
Fixed a bug where screen reader tools for the visually impaired would not read out the items in the source list box in the main window when selected.
Fixed a bug where fullscreen projectors would always be on top despite that setting being unchecked.
Fixed an issue on windows where window capture would use an abnormal amount of CPU usage when its target window was not available
Fixed a number of race conditions and minor memory leaks, improving overall program stability.
When your mouse cursor is hovering over a source in the preview or in the source list, a light rectangle will show up around it indicating that it can be selected.
When a source is dragged outside of the preview area, there is a new visualization for the unseen area of that source while selected.
Simplified and improved the user experience of the "Stream" page of both the settings and auto-configuration windows.
The source selection rectangle has been improved.
The slideshow source now only loads a maximum of 15 images at a time, and dynamically loads images beyond that count as they cycle. This was done to prevent people who put countless files in the slideshow source from running out of memory.
When in studio mode, you can no longer transition if you're already in the middle of a transition.
Removed a number of internal/uncapturable Microsoft program windows from the game/window capture window lists.
Increased the Instant Replay script retry interval.

New in OBS Studio 22.0.2 (Aug 31, 2018)

New in OBS Studio 22.0.1 (Aug 20, 2018)

New in OBS Studio 22.0.0 RC 2 (Aug 18, 2018)

New in OBS Studio 22.0.0 RC 1 (Aug 13, 2018)

GENERAL CHANGES:
Added a "Vertical Layout" option to the right-click context menu of the mixer to make the mixer display vertically rather than horizontally (#1257)
The multiview can now be configured to show up to 24 scenes at once in general settings if desired (#1260)
Added an option to advanced settings to allow the user to change the audio meter type: "Sample Peak" and "True Peak" (#1189)
Added secure streaming (RTMPS) support for services that support it such as Facebook (#1360)
It is now possible to use more than one Intel QSV encoders at once (#1341)
It is now possible to use alt-cropping even on sources that are set to a bounding box transform. This fixes the issue where, for example, alt-cropping would not work after you pressed Ctrl-F on a source. Note that in that case, the rectangle's size will not change, but the contents will realign to the rectangle. (01ac60c)
Window projectors are now saved and loaded on shutdown/startup (#1195)
Audio sources within the mixer now always displayed alphabetically (#1242)
Significantly reduced GPU usage when the program is idle (I.E. when the program is not streaming or recording) (45b5291)
Added a confirmation dialog when the user has not added video sources, warning them that they are about to stream a blank screen. This ensures that new users do not inadvertently stream without at least first adding some sources. (310c98e)
The program will now default to the NVIDIA GPU when on laptops that have both NVIDIA and Intel integrated adapters
Added source grouping, allowing the ability to group multiple sources together as a single transformable group:
To add a group, you can select a few sources, then right-click and choose "Group Selected Items", or you can create an empty group in the add menu
Groups show their list of sources as a sub-list within the main scene list, which can be collapsed
Groups can be shared between scenes, and thus can be duplicated or referenced between multiple scenes
Groups and can have their own effect filters applied to them
You can seamlessly drag and drop items in and out of groups, or ungroup seamlessly
Completely reworked the browser source:
Refactored the entire plugin and pruned 13,000 lines of code (very satisfying for me in particular)
Added a hardware acceleration option to the browser source on Windows for greatly improved performance, reduces resources, and allows advanced rendering functionality such as WebGL. This option is enabled by default, but can be disabled in advanced settings.
The browser source now has accurate frame synchronization on Windows
Fixed all memory leaks of the browser source
Added the ability to use web browsers as widgets (which isn't currently exposed much, but will allow a lot more custom functionality later)
Added the ability to set a custom background color to items within the source list to color-code them for improved organization:
To set the item's background color, right-click the source item within the source list, and go to "Set Color"
You can use a preset selection of colors within the menu, or you can choose a custom color
BUG FIXES:
Fixed a bug where the active monitoring device wouldn't property change when switching between profiles (#1258)
Fixed a bug where pasting filters without a destination source selected would cause a crash (b0cd7fe)
Fixed a bug where projectors would close whenever "Always On Top" was toggled (#1207)
Fixed a bug where the recording option "Generate file without space" was not working with the replay buffer (#1276)
Fixed a bug size where certain cursors would appear the incorrect size in Game/Window/Display captures on Windows (#1284)
Fixed a bug where in-program links would show up with a bad contrast (dark blue) even in dark themes (e1ab9a0)
Fixed a bug where stream output would stop if a stinger transition had a very late transition point assigned to it (an invalid floating point calculation would be put in to the audio data, which would in turn cause the audio encoder to fail and stop encoding, and thus stream output to stop) (0bd2e23)
Fixed a bug on mac where VLC would not be found for the VLC source (ec366cf)
Fixed a bug on macOS where audio monitoring devices would not show up correctly, and a few minor issues with audio monitoring on macOS (#1318, #1345)
Fixed a bug where Mixer's FTL service would cause a crash on macOS (#1374)
Fixed a bug where the color property (when showing the properties of sources/filters) would not show the actual color the user had set it to (#1305)
Fixed a bug where hotkey labels would not update when sources and transitions are renamed, and could cause the hotkey to not be saved correctly (#1310)
Fixed a bug where creating a new profile with advanced output mode active would not enforce the service's settings (such as keyframe interval) (310c98e)
Fixed a few minor memory leaks (#1287, #1292)

New in OBS Studio 21.1.1 (Mar 22, 2018)

New in OBS Studio 21.0.3 (Feb 25, 2018)

New in OBS Studio 21.0.2 (Feb 7, 2018)

Highlights:
Fixed an issue with Qt 5.10 moving the macOS theme to a plugin
Additional packaging to make sure Lua works on macOS
Fixed MP3 audio support in the browser source on macOS
Known Issues:
Python scripting is currently disabled on macOS
VST plugin sizing may be off on some systems (manually resize for now)
Scripting:
Added Luajit/Python3 scripting support. Scripting can be accessed via the "Tools" menu -> "Scripts".
Lua is supported via Luajit, which comes with the program. Lua is recommended for high-performance scripts, automation, and sources.
Python is available if access to its convenient libraries is desired. On windows, to use Python, Python version 3.6 must be installed separately ("x86-64" version if 64bit OBS Studio, "x86" version if 32bit OBS Studio), and the Python 3.6 install path must be configured in the Python settings tab.
Scripting documentation can be found in the developer documentation: https://obsproject.com/docs/scripting.html
Added an example Lua script: An "Analog Clock" source which draws an analog clock (added like any other source when the script is active)
Added an example Lua script: A "Countdown Timer" script which sets the text of a text source to a countdown timer which counts down when that text source is displayed on stream.
Added an example Lua script: An "Instant Replay" script which automatically saves a replay if there's an active replay buffer, and then plays back that replay in a specified media source after that replay has saved.
Added an example Python script: A "URL Text" script which sets the text of a specified text source to the text downloaded from a specified URL every specified interval.
New Audio Features:
Added sidechain/ducking support to the compressor filter. This allows the ability to lower the audio level of an audio source based on how loud another source is. For example, to apply microphone ducking to a desktop audio source, add a compressor filter to the desktop audio source, then select the microphone audio source in the "Sidechain/Ducking Source" property.
Added surround sound audio output support, which allows outputting 2.1, 4.0, 4.1, 5.1, and 7.1 audio to stream/recording. (When using this feature, please also make sure to increase your audio bitrate to support all the channels in output settings. Although some services like Twitch support it, note that certain services such as YouTube may not fully support surround sound streaming, and may not downmix them correctly for stereo viewers)
Added new audio meters to allow the ability to see the audio levels of each audio channel of that source. This allows the ability to know if there are any issues with a specific audio channel (e.g. if just the left or right audio channel is somehow low or muted).
Changed audio meters to behave like peak programme meters. This will make it easier to see if your audio is clipping and set your audio levels correctly. For more information, see: https://obsproject.com/wiki/Understanding-The-Mixer
Added an "Audio Meter Decay Rate" option in audio settings to allow selecting a specific delay rate (fast, medium, slow) for the audio meters if desired.
Added the ability to rename audio sources via right-clicking them in the audio mixer, including desktop and microphone audio capture sources added via audio settings.
New Production and Studio Mode Features:
Added a "Multiview" projector (accessible via the View menu), which allows the ability to view the preview/program and up to 8 scenes at the same time. Scenes in the Multiview can be clicked to change the scene (or the preview scene in studio mode). You can blacklist certain scenes from displaying in the multi-view by right-clicking the scene in the scenes list and unchecking "Show in Multiview". You can also change the Multiview's layout style in general settings.
Added an option in general settings that allows you to transition to a scene in studio mode simply by double-clicking on it. This also applies to the multiview projector.
Added separate projectors for both preview and program views in studio mode.
Added a portrait/vertical layout option for studio mode in general settings which makes the preview/program views vertical relative to each other instead of horizontal
Added per-scene transition overriding, which allows you to select a specific transition to use for a specific scene. To use this feature, right-click on the scene in the scene list, and select the transition/duration via the right-click context menu. (This override does not apply to studio mode quick transitions)
Developer Documentation:
Spent about a week or so and finally wrote full developer API documentation/reference (useful for both native and script developers), which can be found here: https://obsproject.com/docs
Other General Changes and Fixes:
Added a new program theme: Acri.
Changed the default program theme to dark mode for new users.
Changed the text of "Multi-adapter Compatibility" in-game capture to "SLI/Crossfire Capture Mode (Slow)". This was changed because the wording "Multi-adapter Compatibility" was a bit vague, and users are not typically aware of the potential performance impact when using the option.
Optimized the preview pane and reduced GPU usage by 2-8% depending on how many sources were in the preview.
The streaming/recording buttons in the main window now highlight while streaming/recording.
Fixed a bug on Windows where desktop audio capture could go slightly out of sync with display/game/window capture on certain audio devices
Fixed an issue where certain Elgato devices would not output audio by default and would require users to select the audio device manually.
Fixed a bug with studio mode where scenes that are set to fully duplicate would not retain their filters.
Fixed a stuttering bug on Linux with audio monitoring
Fixed MP3 audio support in the browser source on macOS
Fixed a few Dark/Rachni theme issues
Fixed a lot of minor bugs and a few minor memory leaks
Fixed a known crash that could happen on startup for certain AMD cards/drivers.

New in OBS Studio 20.0 (Aug 12, 2017)

Added new modular user interface that allows the user to move, disable, and customize elements of the UI. To unlock, go to the View menu, then the "Docks" sub-menu, and un-check "Lock UI". To reset to the default style, use "Reset UI"
Added Stinger transitions, which allow the ability to use video files as a transition with a specific transitioning point timing during playback of the video
Added a new "Auto" server for Twitch which will automatically select the server with the best routing. In addition, Twitch servers are now sorted based on the best route (as determined by Twitch)
Added support for Mixer's FTL protocol which allows low-latency streaming on Mixer. To use, open Settings, go to the Stream section, and set the service to "Mixer.com - FTL"
Added the option to disable looping in the image slide show, and stop or become hidden when all slides have been played
Added the option to change the visibility behavior of the image slide show: Pause when not in the current scene, restart when in the current scene, or always play regardless
Added the option to manually control the image slide show with hotkeys
Added the ability for the blackmagic source to automatically detect resolution/format rather than having to set it manually each time
Added ability to lock sources to prevent accidentally clicking on and modifying the position of a source
Added the ability to zoom in the preview for detailed editing while in canvas/output preview scaling modes. To use, click the preview, then hold down space bar and use the mouse wheel scroll to zoom in/out
Added a "Defaults" button to the filters and properties windows which will reset values to their defaults
Added a new "Rachni" theme
Added a "Fullscreen Interface" option to the view menu
Added the ability to use certain Japanese and European-specific keys as hotkeys
Added the ability to modify projectors from the tray menu
Added a network buffering option to the VLC source
Added a --multi command line option to suppress the multiple instance warnings
Added a "Below Normal" process priority to the process priority option in advanced settings on windows
Audio meters will now temporarily change their color to red when audio is clipping (too loud)
When using the auto-configuration dialog with Twitch, it will now automatically test the 3 servers with the best route
Made a few key improvements to the windows AMD AMF encoder. Fixed a potential crash, added support for AMF 1.4.4, added compatibility for newer drivers such as 17.7.2, and improved support for older drivers like 16.11.5 and 16.12.1
Fixed an issue where the settings window could sometimes get stuck with a bad size
Fixed a bug where cropped sources would have incorrect alpha handling
Fixed a bug where scene collections/profiles wouldn't properly overwrite existing if the user chooses to do so
Fixed a crash that would happen if the program starts on a system with an unsupported video card, the program will now display a message as was originally intended
Fixed various minor bugs

New in OBS Studio 19.0.3 (Jun 23, 2017)

New in OBS Studio 19.0.2 (May 22, 2017)

New in OBS Studio 19.0.1 (May 21, 2017)

New in OBS Studio 19.0 (May 21, 2017)

Added an auto-configuration wizard to the tools menu and on first-time use, which will attempt to automatically test and configure video/encoding/streaming settings based upon your system and internet connection. This wizard is currently in beta and may be subject to change, feedback is appreciated here: https://obsproject.com/forum/threads/obs-studio-19-0-0-auto-configure-feedback-megathread.68509/
Added a stats dialog to the view menu (with the option to show it on start it up in general settings). The stats dialog shows advanced statistics, such as: average frame rendering time, frames lost due to encoding/rendering/network lag, HDD space left in recording location, and how much data has been output total.
Added a "Render Delay" filter that allows delaying non-async video sources such as display capture or window capture. Note this is only meant for minor sync adjustments (e.g. syncing your screen capture to a webcam), and because the delayed frames are stored on very limited VRAM, the allowable maximum delay is 500 milliseconds (which is 250 megabytes of VRAM on a 1080p 60 FPS source)
Added the ability to copy and paste filters between sources
Added Ctrl-E as a shortcut to edit transform of sources
Added a command line option to start as always on top (--always-on-top)
Added a "shuffle" option to the VLC video source
Added the ability to copy and paste sources (with transforms) from one scene to another
Added specific error messages displayed to the user when fail to connect
Added an option to the blackmagic source that allows you to specify the channel format
Added the ability to project a source, scene, or the preview on to a resizable window in the right-click context menu when right-clicking on sources or the preview
Reworked the media source: media files set to activate when switching to a scene will now immediately start play back when you switch to their scene without requiring time to load
Reworked the media source: media files will now loop properly with no abnormalities in sound playback
Fixed a bug where scenes could be unintentionally lost under specific crash circumstances (backup files were always present, but were not being used -- this is now fixed)
Fixed an issue where the blackmagic source can start up or spontaneously go out of sync
Fixed dragging and dropping text files to create a text source on non-windows systems
Fixed a bug where devices outputting NV12 (e.g. Logitech BRIO cams) would have distorted colors
Fixed a bug where frame dropping would not happen properly when using the ultrafast x264 preset
Fixed a bug from 18.0.2 where "downmix to mono" would no longer save
Fixed a potential crash under specific circumstances when OBS is set to minimize to task tray
When dragging and dropping text files to create a source, those sources will now have the same name as the text file being dropped
All dialogs should now have close buttons (useful on certain window managers such as gnome)
Filter names are now sorted when adding new filters
Fixed an issue where you would not always be able to select all available fonts in the text source

New in OBS Studio 18.0.1 (Mar 9, 2017)

New in OBS Studio 18.0 (Mar 9, 2017)

Added audio monitoring on Windows/OSX. Audio monitoring allows the ability to listen to the audio of a source, and can be enabled via the advanced audio properties. You can set it to monitor without outputting, or monitor and output. The device used for monitoring can be changed in advanced settings
Added an audio compressor filter
Added a "Color" source which displays a solid color
Added a VST audio filter for Windows/OSX. Allows applying VST plugins (only up to version 2) to filter audio
Added a network connection stability indicator similar to classic, displays green for no congestion, yellow for increasing congestion, to red for beginning to drop frames
Added separate timers to the status bar for streaming and recording
Added options to general settings: Always minimize to tray, save/restore projectors on startup/shutdown, and options to automatically start replay buffer
Added command line options: --startreplaybuffer, --minimize-to-tray
Added an option for ultrawide -> wide scaling distortion to the scaling filter
Added an "Apply LUT" video filter, which allows applying a lookup table to modify a source's colors
Added a warning message if starting stream/recording fails
Added configurable GOP size to FFmpeg output
Added a checkbox to custom FFmpeg output that allows using any codec with a container format (due to the fact that it can display fewer codecs than are typically compatible with certain containers, though note that it may fail if an incompatible codec is chosen)
Fixed a bug where mixing visible/invisible sources would sometimes cause the audio of the visible sources to stop outputting
Fixed a performance issue with audio meters that could cause audio latency to increase unintentionally, or cause issues with some devices
Fixed issues resizing a source when the source is flipped horizontally/vertically
Fixed a few potential crashes/freezes
Fixed a potential crash with the browser source and updated to chromium 57
Improved accessibility text on the main window
Cleaned up the general pane of the settings dialog a bit

New in OBS Studio 0.16.2 (Oct 31, 2016)

New in OBS Studio 0.16.1 (Oct 31, 2016)

New in OBS Studio 0.16.0 (Oct 31, 2016)

Added a automatic scene switcher via the tools menu on windows/mac (and linux eventually) that can switch scenes based upon what program/window is currently in focus on the system. More features to be added in future versions. On macs, you can only select applications, not windows. Note that you can also use regex to match a window name.
Added a system tray icon, with the ability to control the program via the system tray, and the ability to hide to system tray.
Added the ability to drag and drop image/video files in to the program to create new sources on the fly (note that on windows this may not work properly if the program is running as administrator, the source being dragged from may also need to be run as administrator)
Added an FPS indicator to the status bar, mostly used to diagnose whether a source in the scene is causing rendering to lag.
Added a "b-frames" option to the NVENC encoder, and set the default to 2. Also fixes an issue where b-frames weren't being used by default, which would impact video quality.
Added a front-end API for developers
Fixed an issue where frames wouldn't drop under certain circumstances and become more delayed than expected.
Fixed an issue where the program couldn't connect to certain types of custom servers.
Fixed a bug where NVENC H.264 profile wouldn't be set.
Fixed a bug with the browser source that would cause it to sometimes freeze under certain circumstances (especially changing settings, deleting the source, starting the program, or shutting down the program).
Fixed a bug where URLs wouldn't work with the VLC video source.
Fixed a bug where hidden sources used by the slideshow source would show up in the "existing source" list when adding a new image.
Streams will now always stop after a maximum of 30 seconds regardless of buffering (though buffering should no longer happen)
You can now click "Stopping Stream..." or "Stopping Recording..." to force them to stop if they are stuck in a "stopping" state for whatever reason (typically streaming, caused by buffering such as with the aforementioned frame drop issue)

New in OBS Studio 0.15.3 (Aug 8, 2016)

New in OBS Studio 0.14.2 (May 16, 2016)

Fixed a potential freeze when reconnecting
Fixed a potential crash when disconnecting on program shutdown
Fixed a bug with transitions where under certain circumstances the audio from the target scene would not start playing until the transition was completed
Fixed a few potential freezes and other bugs with the media source
Fixed a bug where using "rescale" with the QSV encoder wouldn't work properly
Fixed a bug where deinterlaced sources would sometimes appear vertically flipped when deinterlacing was enabled
Fixed a bug where alt-crop wouldn't work properly if a source was flipped
Fixed a bug where you couldn't save a recording to a file or path that contained unicode characters
Fixed a bug where simple output mode would not record QSV at the expected bitrates relative to "high" and "indistinguishable" quality on haswell+ processors
Fixed a bug where switching from a scene collection with custom transitions could corrupt the scene collection being switched to
Fixed an issue where the browser plugin would have poor performance under certain circumstances
Fixed an issue where the browser plugin wouldn't play back WebGL
Fixed an issue where NVENC would use too much bitrate unnecessarily when recording, now uses CQP instead of VBR
Fixed an issue where NVENC constant bitrate wasn't working properly
Window capture on windows will no longer display anything if the window has been closed and can no longer be found. Before it would display a frozen image of the window before it was closed
Game capture on windows will now prevent itself from hooking OBS projector windows when game capture is set to capture any fullscreen program
Game capture on windows will now try to initialize capture immediately when possible, especially on games/programs that are already hooked
Game capture on windows no longer acts as a global source, and when not being shown it will fully deactivate (for example it's in another scene). This fixes an issue where game capture would sometimes show a black screen if there were other separate game captures in different scenes capturing the same thing
Monitor capture on windows no longer acts as a global source, and when not being shown it will fully deactivate (again for example when it's in another scene). This fixes an issue on windows 8/10+ where monitor capture would cause unexpected lag while in a different scene when a fullscreen game is active
Projectors no longer minimize if the main window is minimized
If the main OBS window was closed on a monitor that's no longer plugged in, it will now start up on the main display rather than starting up off-screen
When changing encoders in advanced output mode, settings from the previous encoder will no longer try to apply to the new encoder, which may have a completely different setting layout
Changed the browse dialogs for the remux dialog to show the various supported file types rather than just FLV/MP4
Changed x264 and NVENC to have a "rate control" setting instead of a "Use CBR" setting
Increased NVENC bitrate limit
Added CQP rate control mode to NVENC encoder interface
Added lossless rate control mode to NVENC encoder interface
Added CRF rate control mode to x264 encoder interface (functions the same as when you're using VBR with 0 buffer size)
Added ABR rate control mode to x264 encoder interface (functions similar to CBR but without bitrate padding)
FFmpeg now is compiled with VP8 and VP9 support on windows

New in OBS Studio 0.14.1 (Apr 25, 2016)

New in OBS Studio 0.12.4 Alpha (Dec 13, 2015)

New in OBS Studio 0.12.0 Alpha (Sep 24, 2015)

Added pre-configured recording quality presets to simple output mode for easy recording-specific configuration
Added stream delay feature (in advanced settings). If spontaneously disconnected during a delayed stream, it will preserve the point of disconnection (optional, on by default), and start off where it left off at the cost of increasing delay until reconnected.
Added automatic data file backup as well as methods to prevent user data file corruption due to things such as program crash, system crash, or otherwise
Added the ability to duplicate a scene (added to the right-click context menu)
Added the ability to update services and servers on the fly remotely (this way we can keep services up to date for all users immediately)
Added support for Blackmagic Intensity Pro 4k
Added a profiler to the back-end to help to help determine potential system bottlenecks
Added custom muxer settings to FFmpeg output in advanced output mode
Changed the back-end to use a windowless graphics context (mostly as a refactor, but to also allow things like CLI-only front-ends later)
Changed the FFmpeg output in advanced output mode to allow the use of generated filenames rather than overwriting the same file over and over again
Changed default theme icons to look better and more consistent, especially in comparison to the dark theme
Changed the video settings so that changing base resolution would not modify the scaled output resolution if they are of the same aspect ratio
Moved reconnect options to advanced settings to clean up output section interface
Removed "Enable CBR option" from simple output stream settings. CBR is always on for streaming (unless service-specific settings are disabled in advanced output mode stream settings)
Removed 22.05khz audio sample rate selection from audio settings
The program will now prevent the computer from going to sleep and screen saving while active
Improved CoreAudio AAC encoder logging
Fixed a bug with the properties window where the window would always start off at the smallest size
Fixed a bug with the media source where streams and certain files would not play audio
Fixed a bug where adding certain audio sync offsets could cause the program to crash
Fixed a bug where canceling reconnection would cause the user to be unable to start the stream again until the program was restarted
Fixed a bug with FFmpeg output in advanced output mode where it could crash when selecting certain extensions
Fixed an issue where log entries could repeat endlessly without limit (now caps log duplication after a certain limit)
Fixed an issue where the program would not start up at all if certain settings were no longer valid
Added Apple VideoToolbox Encoders. These are considered experimental and not recommended for streaming yet. Currently only available in the advanced output mode.

New in OBS Studio 0.11.2 Alpha (Jul 28, 2015)

New in OBS Studio 0.11.1 Alpha (Jul 10, 2015)

New in OBS Studio 0.11.0 Alpha (Jul 9, 2015)

General Changes:
Added profile support (currently just via a menu option) to allow you to save and change to different settings profiles
Added scene collections (note that scene collections are fully functional even while streaming/recording)
Added the ability to select the type of container format to save recordings to in output settings (mp4, mov, ts, mkv, flv). If the program unexpectedly terminates while recording, the recording file won't be corrupted. (Corruption can still occur if the entire computer is shut down/restarted while recording however)
Added the ability to save multiple audio tracks with different mixer configurations on a single recording in advanced output settings (supported by mp4, mov, ts, mkv, but not flv)
Added portable mode option, which allows the program to save and access configuration data from the program's base folder. You can enable portable mode by using the --portable or -p command line parameter, or by having the following file in the base program directory to enable it: portable_mode or portable_mode.txt
Added support for Apple's CoreAudio encoder for better audio encoding quality (always available on mac, and should be available on windows if the user has itunes or quicktime)
Added a scroll effect filter (which had been highly requested for things like text)
Added a noise gate audio filter
Added a gain audio filter
Added a settings icon to audio sources on the mixer so that you can configure their audio filters or properties
Added a "Show" button to stream key edit boxes to allow you to disable the password masking
Added a few of common services: livecoding.tv, beam.tv, gaminglive.tv (service handling is still scheduled for an overhaul to use things like remote APIs and remote server lists so we don't have to control a primary list)
Added the ability to reorder scenes
Added the ability to easily reorder scenes/sources by dragging items in the list boxes
Added support for username/password authentication when using custom servers
Fixed a potential major memory leak with async video sources (video devices, media sources)
Fixed a faulty design with the blackmagic source where its audio/video wouldn't be guaranteed to be in sync
Fixed a bug where audio filters would add hotkeys
Fixed a crash that could happen when connecting to a server
Fixed a crash that could happen on exit or when closing certain dialogs
Fixed a bug where sources could linger even though they aren't used in any scenes
Fixed the way preview panes work so they don't have that weird "stretching" look when resizing the window
Fixed http/https support (for things like update checks) to use libcurl, windows users should now always be able to get update checks and upload log files
Fixed the default scaled resolution value to always be at or below 1280x720
Fixed a design flaw in the media source where the audio/video would not sync up properly
Fixed a bug in the media source where certain files would freeze on the first frame

General:
Added support for additional base color output formats: YUV 4:2:0, YUV 4:4:4, and RGB, primarily meant for increasing recording quality (Note that RGB should not be used with x264, use YUV 4:4:4 instead)

Added the ability to disable the preview window via the preview context menu
Added "fullscreen projector" feature that allows you to view a source, scene, or the preview in full screen on a specific monitor

Added a low-resolution downscale shader to increase quality when downscaling past 2x base resolution
Added up/down/left/right keyboard shortcuts when in the preview to allow to fine-tune the position of source(s) by a unit
Changed reconnecting to show a timeout countdown
Changed reconnecting so that it doubles the timeout per attempt to reduce potential server requests in case of unexpected downtime
Fixed a design flaw where I-frames could be dropped when frame drops occur, which could cause issues with HLS and any calculations based on I-frames
Fixed a bug where async video sources that may internally resize (such as mac window capture) would cause a potential data race crash
Fixed a crash that could occur when exiting the program
Due to a changed ini variable name, window positions/sizes may be reset to default initially when first running this version
Mac:
Fixed a bug where window capture could crash (cross-referenced in general changes above)
Fixed a bug where the "Show Cursor" wouldn't do anything (which would also cause the cursor to not get captured in display capture on OSX 10.10+)
