Doesn't using RGB 8-bit (4:4:4) lose quite a bit of luma (and other) information relative to YUV 10-bit 4:2:x? I.e. it's fewer bits but with RGB you don't have chroma subsampling so perceptually it's less information? > Also, sometimes people confuse 10bit production with 10bit encoding. 8bit > sources can be encoded using 10bit encoding to avoid common encoding > artifacts like banding.

The goal is to take 10-bit-per-component YUV video (TBD 709 vs 2020) and cut it and apply a few effects without losing quality. I.e. 10-bit=>MLT=>10-bit without quality loss.
