Yes, SheerVideo supports real-time lossless encoding and decoding of wide-range data: Y’CbCr 8bw 4:2:2, both progressive and interlaced, at all resolutions and frame rates, on both Mac and Windows. The wide-range Y’CbCr 8bw 4:2:2 pixel format supported by SheerVideo is known as ‘yuvu’ or ‘yuv2’. Y’CbCr 8bw 4:2:2 ‘yuvu’, ‘yuv2’ In SheerVideo codec and format names, the w designation following the precision designation indicates that the data is wide-range: • Sheer Y’CbCr 8bw 4:2:2 In 8-bit wide-range video data, the chroma components have a wide range of 255 possible values, represented as two’s-complement signed integers [-127..127]->[-1/2..1/2], while the luma and alpha components use the full range of 256 unsigned integer values in the range [0..255]->[0..1]. While this format leaves no play for filter slop, it can represent significantly more displayable colors than the corresponding 601-compliant format, making it more useful for storage of video from higher-precision sources.
