What's new in SheerVideo Reader 2.6.5.2
Jul 27, 2007
- Support for the Y'CbCr 8bv 4:2:2 pixel format HDYC ('CYDH') used by Blackmagic Design has been added to the Sheer AVI codecs. This pixel format is identical to UYVY ('YVYU'), except that they use the HD color space specified in ITU-R BT.709-2, rather than the SD color space specified in ITU-R BT.601-4.
New in SheerVideo Reader 2.6.4.13 (May 24, 2007)
- Adobe Premiere Pro rejected most Sheer AVI codecs because their 'ICM_COMPRESS_GET_FORMAT' methods specified the actual pixel precision in the 'biBitCount' field of the 'bmiHeader', for example 30 bits per pixel for Sheer RGB 10bf, or 40 bits per pixel for Sheer RGBA 10bf; and 16 bits per pixel for Sheer Y'CbCr 8bv 4:2:2, or 24 bits per pixel for Sheer Y'CbCrA 8bv 4:2:2:4. Instead, Premiere always needs to see a value of 24 for any color pixel with at least 8 bits per component, and a value of 32 if alpha is included � the same convention used in QuickTime.
New in SheerVideo Reader 2.6.3.7 (May 7, 2007)
- The Sheer Y'CbCr 10bv 4:4:4 encoder falsely advertised that it accepted 'b48r' input pixels. As a result, Sheer Y'CbCr 10bv 4:4:4 encoding failed for applications choosing the 'b48r' pixel format for high-precision RGB data. The Sheer Y'CbCr 10bv 4:4:4 encoder no longer includes 'b48r' in its list of input pixel format, so this problem has been fixed.
New in SheerVideo Reader 2.6.1.1 (Mar 1, 2007)
- In accordance with the SheerVideo for QT codecs, the Video Standards in the SheerVideo for AVI codecs have been changed in v2.6.1.1 from obscure ITU and SMPTE standards to the friendlier terms NTSC, PAL, HD, and HD 1035, where NTSC replaces ITU-R BT.601-4, HD replaces ITU-R BT.709-2, HD 1035 replaces SMPTE 240-M-1995, a separate choice has been added for PAL, and an additional choice has been added for Unknown video standards.
