Sorry about the slow response, that has fixed the issue, thanks chronek!
The file still seems a bit soft in quality though. I have tried turning the
-qscale right down to 1 and adjusting the bits_per_mb up to 2400 and the
picture improved but it still wasn’t 100%, but the file grew to 2.5x the size.
I tried with the prores codec as opposed to the prores_ks codec and it was
better, but again not 100% interestingly the file size didn’t grow when using
the bits_per_mb with prores.
Here is an example output:
$ ffmpeg -y -i "5082197_Soccer Enrique Upd.mp4" -acodec pcm_s16le -vcodec prores_ks
-profile:v 1 -vf scale=interl=1 -sws_flags full_chroma_inp+full_chroma_int -copytb -1
"5082197_Soccer Enrique Upd.mov"
ffmpeg version 3.2.2-tessus Copyright (c) 2000-2016 the FFmpeg developers
Note scale=interl=1 recently changed (hopefully for the better).
You may want to test again with git.
Sometimes adding +accurate_rnd can help, though IIRC it 420 -> 422
8 bit was unaffected, don't know about 10bit.
Interlaced 420 -> rgb really does need it + the other flags.
