Sheer Y'CbCr 8bv[A] 4:2:2[:4]


Sheer Y'CbCr[A] 8bv 4:2:2[:4] Sheer Y'CbCr[A] 8bv 4:2:2[:4] is for cutting and archiving standard-precision digitized video.

This codec perfectly encodes all Y'CbCr[A] 8bv 4:2:2[:4] source footage in real time, with an average compression power of 2.43, so that the Sheer Y'CbCr[A] 8bv 4:2:2[:4] files take up only 41% as much space as the uncompressed Y'CbCr[A] 8bv 4:2:2[:4] originals, with zero loss of information.

Sheer Y'CbCr[A] 8bv 4:2:2[:4] both encodes and decodes losslessly in real time from and to all Y'CbCr[A] 8bv 4:2:2[:4] pixel formats ('2vuy', '2Vuy', and 'yuvs'), making it ideal for processing in those formats.

This codec also losslessly decodes to Y'CbCr[A] ≥9b 4:2:2[:4] pixel formats ('v210', 'v216', and 'Y216').

In addition, Sheer Y'CbCr[A] 8bv 4:2:2[:4] uses Synchromy to decode with minimal loss to RGB[A] pixel formats ('b64a', 'L64A', 'A46L', 'F10k', 'F210', 'R10k', 'r210', 'S10k', 'S210', 'VRGB', ARGB, and, on PC+Windows, ABGR, RGBA, BGRA, RGB, and BGR) and to Y'CbCr[A] 4:4:4[:4] pixel formats ('r4fl', 'V416', 'v410', 'v408', 'VUYA', and 'r408').

Note: For nondestructive coding of the obsolete wide-range 'yuvu' or 'yuv2' (Y'CbCr 8bw 4:2:2) pixel format, use the Sheer Y'CbCr 8bw 4:2:2 codec.
