Part of overall #118493 task: video input/output support at 10 and 12 bit/component formats. (note: this is still LDR videos just at higher precision; there's no HDR handling (yet)). Movie reading/playback: when movie file pixel format has >8 bit components, decode those into a floating point ImBuf result. Previously all movies were decoded into 8 bit/channel ImBufs, so 10- and 12-bit movie pixel colors were getting quantized. Movie output: when ffmpeg video with suitable codec is selected, there's a color depth setting under Encoding block. Currently that is: - 10 bit option for H.264, H.265, AV1 (VP9 could do 10 bit in theory too, but ffmpeg that is built in Blender does not have that compiled in) - 12 bit option for H.265, AV1 When "lossless" is picked, then similar to how for regular 8-bit video it switches from YUV 4:2:0 to 4:4:4, this also switches to 4:4:4 10- or 12-bit variant.
