Sheer Y'CbCr 8bw 4:2:2


Sheer Y'CbCr 8bw 4:2:2 Sheer Y'CbCr 8bw 4:2:2 is for cutting and archiving standard-precision digitized video that has been digitized in the obsolete format 'yuvu', or 'yuv2' .

This codec perfectly encodes all Y'CbCr 8bw 4:2:2 source footage in real time, with an average compression power of 2.32, so that the Sheer Y'CbCr 8bw 4:2:2 files take up only 43% as much space as the uncompressed Y'CbCr 8bw 4:2:2 originals, with zero loss of information.

Sheer Y'CbCr 8bw 4:2:2 both encodes and decodes losslessly in real time from and to all Y'CbCr 8bw 4:2:2 pixel formats ('yuvu' and 'yuv2'), making it ideal for processing in those formats.

The Sheer Y'CbCr 8bw 4:2:2 codec is provided for backward compatibility only, and does not support alpha or Synchromy. The wide-range Y'CbCr 8bw 4:2:2 pixel formats are considered obsolete, and have been superseded by video-range Y'CbCr 8bw 4:2:2 pixel formats.
