[FFmpeg-user] "fps 2997 is too large" - creates mov with bad public atom (error -2002

[Steve C]

okay, I figured out how to use git, at least enough to test with
-checkout 9362f31.

here are the results of testing with the 'git checkout 9362f3' of ffmeg

used the same command statment on three or four different ProResHQ.mov
source files.

ffmpeg -i /Source-Files/035925_NTSC_ProResHQ_EM.mov -c:v copy -c:a
copy -report /Users/ffmpeg/Desktop/output-4.mov

with -checkout 9362f31 the results were the same each time. I dont see
the same timecode error as before ("fps 2997 is too large"),
but the timecode on the output file is still not correct.

it seems the FFMPEG is still having trouble with the the timecode track.
each time the log message shows:   [mov @ 0x101cc1800] timecode:
tbc=2997/1 invalid, fallback on 2997/100

Please see below for the full output from one of the test files.

Anyone have any other suggestions as to what else I can try?
