Yes, that file should play back fine, that is an example of the source file.
The problem starts when you try to use -c:v copy
FFMPEG shows an error:
"fps 2997 is too large"
play back the output file with quicktime it says:
"Error -2002: a bad public movie atom was found in the movie"
You can get -c:v copy to work, but you have to also use -timecode
00:00:00:00 -r 29.97 in the command statement.
I don't understand why -timecode and -r are needed to make this work.
I'm guessing it has something to do with the drop-frame timecode on a
because when I take a ProResHQ.mov with non-drop-frame timecode (PAL, 25fps)
i can get the -c:v copy command to work with no errors.
hope that helps.
thanks for testing this out, glad its not just me.
