I was unable to get dxnhd codec running, it always complained about something :/ DNxHR still doesn't show up as interlaced ......
What a lot of work you do, thank you very much! Of the DNxHD codec there are many specifications for each combination of resolution, bit rate and depth color. It is an unmanageable codec because it always finds compatibility problems. Basically only Avid used it. This is why DNxHR was created, which imitates the formats and flexibility of ProRes. The only rigidity of DNxHR are 4:2:2 or 4:4:4 (like ProRes) and the lack of interlacing, it can only be progressive. PS: There is also another famous high quality format: Cineform (GoPro property, but open). I've seen that it has big problems of slowness and compatibility with ffmpeg, so I didn't try to create presets.
