Comment (by dericed):

 @cehoyos. I added mpeg4 versions of the sample files.
 I created tbe before file with "ffmpeg -f lavfi -i testsrc=d=5
 5seconds_cut_with_QT_using_mpeg4_before_QT_save.mov".
 I then duplicated the file and named the copy "ffmpeg -f lavfi -i
 testsrc=d=5 5seconds_cut_with_QT_using_mpeg4_after_QT_save.mov". I then
 opened the file in QuickTime Pro 7, edited some frames from the beginning
 and end and hit save.
 When I now open "5seconds_cut_with_QT_using_mpeg4_after_QT_save.mov" in
 Quicktime it will start on frame number 1 and the 'before' file starts on
 0. For ffmpeg both files present the same, starting from 0.
