What's new in Natron 2.6.0 Pre-release

Dec 8, 2022
  • This is a test snapshot based on Natron 2.5 with Qt5.
  • It has the same bugs as the Qt5 version, see #827

New in Natron 2.5.0 (Nov 29, 2022)

  • Changes (compared to 2.4.4):
  • Use Python 3 rather than Python 2 (which is not maintained anymore). This will require very few changes to the Python code (mainly print statements), and most code can be easily adapted to be 2-3 compatible. #686
  • Use QtPy==1.11.2 rather than PySide. QtPy is an abstraction layer for PyQt5/PyQt4/PySide2/PySide (newer versions support PyQt6/PySide6). QtPy uses the Qt5 layout (where the QtGui module has been split into QtGui and QtWidgets). Using QtPy guarantees a higher level of forward-compatibility with future versions of Natron, which may use Qt5 or Qt6. PySide can still be imported explicitly, if required, but the resulting code will not be forward-compatible. Note that 2.4.4 binaries include qtpy, but still import PySide by default. #687

  • fix bug when creating a group from a plugin with invisible inputs (e.g. Shadertoy)
  • fix bug where Natron would crash when the "clear all panels" button is pressed #1729
  • fix bug where Roto and RotoPaint lifetime would change randomly #1707
  • Plugins:
  • ReadOIIO/ReadPNG: "Image Info..." gives a more explicit message, containing the filename and more info.

New in Natron 2.3.4 (Dec 19, 2017)

  • Binaries distributed through Natron's web site are now built with 8-bit x264. 10-bit x264 (introduced with 2.2.6) causes too many compatibility issues. There are other codecs that support 10-bit output (especially ProRes, vc2, libopenjpeg, libvpx-vp9, and x265 on some systems). In order to get 10-bit x264, it is recommended to encode a quasi-lossless using one of these codecs, and then transcode with a ffmpeg binary capable of encoding 10-bit x264.
  • Work around a possible Qt/Linux bug where tablet events have a negative pressure on Wacom Intuos tablet #1697

  • ColorCorrect: Fix wrong render for input values outside the [0-1] range #1703
  • ReadOIIO: Adjust Maximum Thr. (used when reading RAW camera files) should defaut to 0.0 #1705

New in Natron 2.3.3 (Nov 13, 2017)

  • Fix computation of remaining time when rendering.
  • Fix loading third-party plugins on Linux #1682
  • Plugins:
  • ColorLookup: add "Master Curve Mode" parameter, which enable selecting different algorithms to apply the tone curve with more or less color shifting. These curve modes are inspired by RawTherapee. Also add the possibility to compute and display the RGB histogram of the source input.
  • WriteFFmpeg: support 10-bit DNxHR 444 and DNxHR HQX (and fix a related FFmpeg bug).
  • Shadertoy: rework many presets so that they work better with Natron, especially the effects in the Blur, Effect, and Source categories. Most blur effects can also be modulated per-pixel using the "Modulate" input to get Z-dependent blur.
  • Shadertoy: new presets: Blur/Bokeh Disc, Blur/Mipmap Blur, Effect/Anaglyphic, Effect/Bloom Paint, Effect/Sawnbringer 4bit, Effect/Sharpen, Effect/CRT, Effect/Fisheye, Effect/Image Cel Shade, Effect/Kaleidoscope, Effect/Noisy Mirror, Effect/Quad Mirror, Effect/Q*Bert-ify, Effect/Stripes, Effect/Vignette, Source/Cloud, Source/Cloudy Sky, Source/Disks, Source/Fireball, Source/Flash, Source/Seascape, Source/Star Nest, Source/Voronoi

New in Natron 2.3.1 (Jul 27, 2017)

  • Python: Fix the setTable() function of the PathParam class

New in Natron 2.3.0 (Jul 5, 2017)

  • Reduce noise on the roto shape borders #1594
  • Plugins:
  • ReadOIIO: fix bug when reading EXRs with datawindow different from displaywindow.
  • (beta feature) Inpaint: New plugin. Inpaint the areas indicated by the Mask input using patch-based inpainting. Please read the plugin documentation.

New in Natron 2.2.6 (Mar 31, 2017)

  • Multi-dimensional parameters don't automatically fold into a single dimension, except for scale and size params.
  • Binaries distributed through Natron's web site are now built with 10-bit x264 and 10/12-bit libvpx-vp9 support. That means the produced video files may be unplayable on some hardware (e.g. phones or TVs), but Natron should really be used to produce digital intermediates with the highest possible fidelity, which can then be transcoded to more suitable distribution codecs.
  • Better cache usage for Readers, ReadOIIO does not use the OIIO cache anymore (partly due to OpenImageIO/oiio#1632).
  • Fix a bug where custom OpenFX plugins directories would be ignored #1584
  • Add a documentation chapter on importing camera data from PanoTools-based software (PTGui, PTAssembler, Hugin).
  • Plugins:
  • WriteFFmpeg: the preferred pixel coding and bit depth can now be selected, which is very useful for codecs that propose multiple pixel formats (e.g. ffv1, ffvhuff, huffyuv, jpeg2000, mjpeg, mpeg2video, vc2, libopenjpeg, png, qtrle, targa, tiff, libschroedinger, libtheora, libvpx, libvpx-vp9, libx264, libx265).
  • WriteFFmpeg: Bitrate-based (VBR) encoding was removed from the following codecs in favor of quality-based (VBR) encoding, mainly because it should be used in 2-pass mode (using handbrake or the ffmpeg command-line tool): mpeg4, mpeg2video, mpeg1video, flv.
  • ColorCorrect: changed the Contrast formula to make adjustments more intuitive, see https://compositormathematic.wordpress.com/2013/07/06/gamma-contrast/ - this may affect existing projects that used the previously buggy Contrast parameter.
  • LensDistortion: add PanoTools/PTGui/PTAssembler/Hugin model.
  • Card3D can now import/export chan files from Natron, Nuke, 3D-Equalizer, Maya, etc., and txt files from Boujou.
  • Card3D and CornerPin: only show things that are in front of the camera. In cornerPin, point 1 is always considered to be in front.
  • Noise, Plasma: result is now reproductible (a given render always gives the same result).
  • ReadOIIO: add advanced options for reading RAW files.
  • STMap: Use the format of the Source input rather than its RoD to determine the texture size (useful when using an STMap written by LensDistortion).
  • SmoothBilateral, SmoothBilateralGuided, SmoothRollingGuidance: The Value Std Dev. was clamped by CImg to a rather high value (0.1), making the filters almost useless. Fixed.

New in Natron 2.2.5 (Feb 20, 2017)

  • Fix undo when manipulating 2D points in the viewer interact #1576
  • Fix manipulating the interact plugin on non-retiming inputs of retiming effects (e.g. the Retime Map in Slitscan) #1577
  • Fix exporting curves to ascii (eg ColorLookup), and values for xstart, xincr and xend can now be simple expressions.
  • Plugins:
  • DenoiseSharpen: the output is now the noisy source when Noise Analysis is not locked. It is easier to see where there is noise that way, and it also makes the plugin usable in Resolve (which calls render even if non-significant parameters are changed)
  • Generators now may set the output format when Extent=Size (as they do when Extent=Format or Extent=Project).
  • Rework many plugins so that they work better in DaVinci Resolve (all generators including Radial and Rectangle, CopyRectangle, DenoiseSharpen, LensDistortion, HSVTool, ImageStatistics, Position)
  • Card3D (beta): Transform and image as if it were projected on a 3D card.

New in Natron 2.2.4 (Feb 6, 2017)

  • The tracker node can now be offset to track elements that go beyond the bounds of the image
  • The roto node interaction has been improved:
  • The composing of selection is now easier
  • A new button can now toggle on/off the click capture of the bounding box of selected points
  • The smooth/cusp options are now applied we smaller steps and depending of the zoom factor
  • A simple left click is required to cycle through tool buttons and a right click to open the menu
  • A new button in the settings panel allows to clear the animation of the selected Beziers
  • Only the keyframes of the selected shapes are now displayed on the timeline instead of all shapes keyframes
  • CurveEditor: added a filter to display only nodes containing the filter
  • CurveEditor: double-clicking the item of a node will open the settings panel much like a double-click in the NodeGraph does
  • The interpolation submenu of the animation menu of the parameter is working again
  • A simple click on an arrow of the node graph no longer disconnects nodes to prevent mistakes, instead now, to disconnect only with a simple click it is required to hold the control modifier.
  • Playback: The behaviour when using multiple viewers is now much more logical: all viewers are kept in sync and follow the frame range of the viewer that started the playback. The frame range is now per viewer.
  • The frame range is now a property of the project: Each time a Reader node the frame range of the project is unioned with the frame range of the sequence read (unless the Lock range parameter is checked). New viewers that have their frame range untouched will use the project frame range by default.
  • Wacom support for all areas of the software that may need it: NodeGraph, CurveEditor, Viewer, Histogram
  • In addition you no longer need to hold alt to zoom, the middle-button only is required. In the CurveEditor, the zoom direction will stretch the view in that direction.
  • New nodes: Add, Multiply, Gamma, ColorConvert, SharpenInvDiff, SharpenShock
