I am not sure if ffmpeg supports encoding or transcoding of 10bit formats using NVIDIA GPU through scale_npp. 97 I originally asked for an explanation because to me a GPU and a CPU are essentially both just different types of sophisticated calculators, but the response was something like "software is better than hardware" which I realized I tried encoding some 4K HDR files using Handbrake and they look washed out. Are these doing the same thing or something different? I'm reading the ffmpeg documentation and it sounds like you only need a negative map_metadata once to disable automatic copying. mkv AV1 includes 10-bit support in its Main profile. 2+) and 60 (Audacity 3. mp4 or -c:v utvideo might be faster to encode.
