Ah, pix_fmt was not working....

pixel_format=yuv420p was right choice ....

still in some opt files I can see
cin_pix_fmt yuv420p

for example in /usr/share/cin/ffmpeg/video/faststart_h264.mp4

so, what exactly I should use - pixel_format or cin_pix_fmt?

Attached video opts files I saw as working ....

Yes, but first format there usually codec default, not something from opt file?

So, If codec enumerates them starting from yuv411 (as dv codec does)
and I said yuv420 in opt file - I can still pick up right format, but it will be one more manual step?

Try to leave default choise and see with that pix format file will be encoded?

Sorry for additional testing load :/

may be pix_fmt is not working anymore in opt files?
