We try to convert DNxHD files to x264/mp4, to prores we have also try, so
I guess the output format doesn't matter. The output has always wrong
colors, it looks like a wrong gamma value or something similar.
The DNxHD files comes from adobe media encoder and have a bt709 matrix. I
put a picture to the post. The left side is the original DNxHD and the
right side is x264. You see more saturation in the middle tone and all is
a bit darker.
My command is:
ffmpeg -i dnxhd45.mov -pix_fmt yuv420p -c:v libx264 -crf 21 -preset slower
-c:a libfdk_aac -b:a 128k output.mp4
