Comment (by Nicolas):

 Actually no, even mkv/mov does not work. There is no real error given in
 ffmpeg and the file is created, but it doesn't contain any video at the
 end and the video can't be played with VLC / Premiere Pro.

 {{{
 ffmpeg.exe -loglevel debug -ss 6.74 -i
 Canon_Trimming_Error_H264_422_Intra_10bits.MXF -t 1 -c:v copy -map 0:v
 -c:a copy -map 0:a testTransformedToMov.mov
 }}}

 When testing with "-t 2", I get more results :

 With MOV container output, I get a video output, but compression not
 allowed by VLC (aivx).

 With MKV container output, it seems to work.

 With MP4 container output, I get the following error :

 {{{
 [mp4 @ 0000026ab1569080] Could not find tag for codec pcm_s24le in stream
 #1, codec not currently supported in container
 Could not write header for output file #0 (incorrect codec parameters ?):
 Invalid argument
 Error initializing output stream 0:4 --
 }}}

 So it looks like pcm_s24le is not available officially for MP4 ? Same
 here, where can I find the available audio codec list for MP4 container ?
