September 8th, 2008· Support for Avid AVUI ('VRGB') pixel format
· Improved support for nonstandard pixel formats; workaround for iMovie bug.
· Synchromy speed-up.
· Brought Windows PC edition up to date.
· QuickTime 7.5 pixel-format bug workaround.
May 9th, 2008· Decoding Sheer RGB[A] formats to Y'CbCr[A] pixels has been sped up by an average of 6%, due to a new optimization in Synchromny.
April 30th, 2008· iMovie bug workaround: v2.6.7.1: iMovie mistakenly accepts many pixel formats it cannot handle. As a result, Sheer Y'CbCr 10bv 4:4:4 movies imported into iMovie were displayed as blank green, because the preferred pixel format for the Sheer Y'CbCr 10bv 4:4:4 decoders is 'v410', which, although defined by Apple many years ago, is still not supported by iMovie or other Apple applications. Sheer Y'CbCrA 10bv 4:4:4:4 movies imported into iMovie were likewise displayed as blank green, because the preferred pixel format for the Sheer Y'CbCr 10bv 4:4:4:4 decoders is 'V416', a non-Apple custom pixel format. Similar problems may also have occurred for other Sheer decoders. When running under iMovie, all Sheer decoders now offer only pixel formats recognized by iMovie.
April 21st, 2008· Avid Meridien uncompressed support: v2.6.7.0: Support for the RGB[A] 8bv 4:4:4[:4] pixel format 'VRGB' used by Avid's Meridien uncompressed codec has been added to all Sheer QT codecs, making it possible to export uncompressed video from Avid to standard QuickTime applications by setting the 'RGB Input Range' to 'Video range' in the Sheer Settings dialog. Internally, AVUI is a Y'CbCr[A] 8bv 4:2:2[:4] format, but the only pixel format supported by Avid's AVUI QuickTime codec is an RGB[A] 8bv pixel format which we call 'VRGB', to distinguish it from the standard QuickTime 'ARGB' pixel format. Unlike 'ARGB', a full-range RGB[A] 8bf format in which the red, green, and blue components have the range [0..255], the RGB components in 'VRGB' are ITU-R BT.601-4-compliant video-range, [16..235], preserving much of the footroom for subblacks and headroom for superwhites in standard video pixel formats. But since essentially no QuickTime applications other than Avid's can deal with 8-bit video-range RGB[A] data, uncompressed video exported from Avid inevitably gets misinterpreted as full-range, reducing the contrast by over 14%, so that for example true black and true black merely look dark and light grey, respectively.
March 11th, 2008· In SheerVideo Pro v2.6.6.3..v2.6.6.6, the Sheer QT encoders erroneously reverted to progressive mode after the first frame. So for Sheer video tracks supposedly encoded in interlaced mode, the Sheer QT decoders detected that the Sheer format in the header of subsequent frames did not match the expected (interlaced) format, and incorrectly deduced that the encoded data had been corrupted, which they reported as 'codecBadDataErr' (-8969), and did not decode the data. Most applications did not pass this information on to the user, instead continuing to display the first frame as though nothing were wrong. This release fixes the problem at both ends: The Sheer encoders no longer incorrectly revert to progressive mode; and the Sheer decoders now check whether the scan mode has changed, and switch modes accordingly. Footage encoded with SheerVideo Pro v2.6.6.3..v2.6.6.6 play correctly with v2.6.6.7.
