Problem of ffmbc's 23.976fps AVC-I MOV file #181

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
Source file is 23.976fps. After converted to AVC-I MOV, the file could not be 
used in Lightworks NLE Editor.

What is the expected output? What do you see instead?
The MOV file could be used.
When comparing the video fomrat/h.264 profile/ID/Codec, the ffmbc produce a 
different one (ai13) compared with using x264 command line directly (AVC).

-----------------
In short, ffmbc:
Video
ID                                       : 1
Format                                   : ai13
Codec ID                                 : ai13

x264:
Video
Format                                   : AVC
Format/Info                              : Advanced Video Codec
Format profile                           : High 4:2:2@L4.1
Format settings, CABAC                   : No
Format settings, GOP                     : N=1
-----------------

What version of the product are you using? On what operating system?
ffmbc 0.7.1, Linux Fedora 20.

Please provide any additional information below:

- Full commandline run (with -v 3) and everything the program printed
without
the repeating parts.

Please see attached files for full details.

x264 does have any fourcc, so I don't know how you can compare
Also just use -target avcintra 100, no need for any other option

I have changed the command to specify minimum options (target avcintra100)
$ ffmbc -v 3 -i V002-24.mov -pix_fmt yuv422p10le -intra -vcodec libx264
-threads 4 -acodec copy -r 24000/1001 -target avcintra100 -faststart 1
V002-24-ffmbc-2.mov

But the result is the same as before:
Video
ID                                       : 1
Format                                   : ai13
Codec ID                                 : ai13
Duration                                 : 4mn 7s

Thanks and regards,
Patrick

I believe ai13 is the right codec tag. What's wrong with it ?

I think the codec tag is ok.

But if you compared with ffmbc's generated 25fps mov avc file:
Video
ID                                       : 1
Format                                   : AVC
Format/Info                              : Advanced Video Codec
Format profile                           : High 4:2:2@L4.1
Format settings, CABAC                   : No
Format settings, GOP                     : N=1
Codec ID                                 : ai12
Codec ID/Info                            : Advanced Video Coding

a) The ffmbc's 23.976fps is using 'Format : ai13'
b) Format/Format/Info/profile/CABAC/GOP info is not provided.

Attached is the problem when trying to open the ffmbc's 23.976fps mov in
Lightworks editor.
ffmbc's 25fps mov have no problem.
