remux of xdcam mxf to mov is unplayable in Final Cut Pro

[dave rice]

Summary of the bug:

I would like to rewrap MXF files from an XDCam disc to QuickTime for edit in Final Cut Pro. I ran: ffmpeg -report -i /Volumes/XDCAM8004602012511C8/Clip/979_0611_01.MXF -map 0:v -an -c copy 979_0611_01.mov. The resulting file works in QuickTime, VLC, ffplay, etc, but when I open it in Final Cut Pro I get an error "File Error: Unknown File".

I looked in the edts/elst atom and see
Track Dur,Media Time,Media Rate
66,-1,1.0
17318,3003,1.0

When I change the first row to zeros it works. Note, when I run the same process in ffmbc the resulting file does not have the first line with the -1 media time, but only the "17318,3003,1.0" line and works in FCP as expected.

Is this still reproducible with current git head?

[dave rice]

Yes it is still reproducible.
I just pulled git head and reran the process above. The outcome is the same. The file plays fine in QuickTime but Final Cut gives an error and won't open it. The edit list of the output quicktime file still starts with a negative media time (same as noted above).

[Carl Eugen Hoyos]

Could you post a sample?

[dave rice]

I did (see above). The source is at ​http://archive.org/download/SamplesOfXdcamMxfAndQuicktimeRewrappedWithFfmpeg/979_0611_01.MXF

and the output of my command line above is at ​http://archive.org/download/SamplesOfXdcamMxfAndQuicktimeRewrappedWithFfmpeg/979_0611_01.mov. Since the files were large I used the Internet Archive instead of trac.
