[FFmpeg-user] Need to Make ProRes HQ video file with 5.1 audio using ffmpeg

[Mark Scott]

Thank you. I copied and pasted the command line that you suggested, but got
the error message. Input: No such file or directory. Then as a test I ran
my original command and it worked, just with the wrong audio. Here's a
screenshot with the information. I'll look at the links that you provided.
