Hello, Thank you very much. I looked at the web page you suggest and tried the following command but got the following error: #################### COMMAND AND OUPUT c:\ffmpeg\bin\ffmpeg.exe -i test.mov -c:v libx264 -preset slow -crf 22 -c:a copy test.mp4

To not lose quality you'd need to use a lossless encoding with mp4, I think h264 is the only one supported in mp4. If the ProRes is 10 bit, you'd like to compile x264 as 10 bit and then configuration ffmpeg to use it. Then to encode h264 losslessly use -crf 0 -qp 0. There's a section on lossless h264 here: https://trac.ffmpeg.org/wiki/Encode/H.264 <https://trac.ffmpeg.org/wiki/Encode/H.264>.
