Sheer RGB[A] 8bf is for use in applications dealing in standard-precision scanned film and computer-generated imagery.

This codec perfectly encodes all RGB[A] 8bf source footage in real time, with an average compression power of 2.2, so that the Sheer RGB[A] 8bf files take up only 45% as much space as the uncompressed RGB[A] 8bf originals, with zero loss of information.

Sheer RGB[A] 8bf both encodes and decodes losslessly in real time from and to all RGB[A] 8bf pixel formats (ARGB, and, on PC+Windows, ABGR, RGBA, BGRA, RGB, and BGR), making it ideal for editing in those formats.

For faster but lower-quality display, the Sheer RGB[A] 8bf codec can also decode in real time to RGB 5bf pixel formats (B555, and, on PC+Windows, L555 and L565).

This codec also losslessly decodes to RGB[A] >8bf pixel formats ('b64a', 'L64A', 'A46L', 'b48r', 'F10k', 'F210', full-range 'R10k', and full-range 'r210'); and, using Synchromy, losslessly decodes to RGB[A] >8bv pixel formats ('S10k', 'S210', video-range 'R10k', and video-range 'r210'), and to Y'CbCr[A] ≥10bv 4:4:4[:4] pixel formats ('r4fl', 'V416', and 'v410').

In addition, Sheer RGB[A] 8bf uses Synchromy to decode with the minimal loss theoretically possible to Y'CbCr[A] <10bv pixel formats ('v408', 'VUYA', 'r408', 'v210', 'v216', 'Y216', '2vuy', '2Vuy', and 'yuvs').

Sheer RGB[A] 8bf has four variant formats: with versus without alpha, and progressive versus interlaced scan mode. Alpha is selected as a QuickTime setting, and is indicated by an A (Alpha) after the color-space name. The scan mode is selected as a Sheer setting, and is indicated by a p (progressive) or i (interlaced) at the end.

Sheer RGBA 8bf i		with alpha		interlaced scan
Sheer RGB 8bf p		without alpha		progressive scan
