I come from image editing and I was wondering why did you go from 8 to 10 bit instead of directly to 16 bit?
As far as (still) images are concerned a higher bit depth (16 [or 10] bit compared to 8 bit) is ONLY needed IF 8 bit would result in banding/posterization artefacts. However the price is a bigger file size. So how do you guys end up saying "10 bit gives better quality at the same bitrate due to greater precision" ?? IMO, the opposite is the case. 10 bit gives marginally better quality (probably only distinguishable for gradients with banding) BUT needs a higher bitrate (due to greater precision). At the SAME bitrate, I suppose 8 bit would still have better quality. Last edited by lovelove; 22nd June 2011 at 04:39. |

Also, 10-bit is the highest bit depth at which luma motion compensation can be implemented without unpacking to 32-bit. Also, the spec is capped at 14-bit. |

What's the point of 10bit video ? Most LCD displays only use 6bit per channel and dither the result. Seems like massive over kill to me. In direct x or opengl, you can render to 16 or 32bit per channel buffers, but the final result is always clamped down for display.

Audio has used 32-bit intermediate precision (in the form of float) for decades even though the output is only 16-bit. |
