Comment (by cehoyos):

 Replying to [ticket:2044 dericed]:
 > When the input is opened in QuickTime or FCP the first frame of the
 sample is 00:59:14;24 and the second is 00:59:14;25. With the output the
 first frame is 00:59:14;24 but the second is 00:59:14;28.

 Isn't this the expected behaviour given that FFmpeg's mov muxer only
 supports cfr?
