    I tried with other stackoverflow questions but none of them worked. Also I think it is partially because the trim timings are mixed. That is start time can be anywhere between 0-end. When I make it strictly increasing it is working fine.

  • Get Timecode from MP4 generated in Adobe Premiere / Encoder in Python and FFMPEG

    3 novembre 2019, par russellaugust

    I’m writing a script that needs to either convert or re-container an MP4 as an MOV with timecode.

    I have an MP4 generated from Adobe Premiere. If I bring that file back into Premiere, I have timecode. I can see it so I know it is there.

    I can’t seem to extract the timecode track from the MP4. I’ve looked everywhere online and found some discussions around it, but no actual success in extracting the timecode.

    I’ve been using ffprobe to see if there’s any mention of the timecode in the MP4, but having no luck. I’ve tried PyMediaInfo with no success.

    Here’s what ffprobe shows :

    And here was what I started experimenting with in Python.

    from pymediainfo import MediaInfo
    

    
media_info = MediaInfo.parse('demo_SequenceV3.mp4')
    
for track in media_info.tracks:
    
    if track.bit_rate is not None:
    
        print ("%s: %s" % (track.track_type, track.bit_rate))
    
    else:
    
        print ("""%s tracks do not have bit rate associated with them.""" % track.track_type)

    I know I’m not using MediaInfo correctly, but I couldn’t find any documentation on timecode, and to be honest I’m pretty confident it’ll just use FFMPEG’s system of searching for a data track that doesn’t appear to exist.

    Anyone here know enough about this to either get it working or to point me in the right direction ?

    The goal is to re-wrap an MP4 as an MOV and translate the timecode so it is back where it normally is on the MOV.

    EDIT : here is an example MP4 that I need to extract the timecode from :

    https://www.dropbox.com/s/a1euiumiapkpzhn/timecode_demo.mp4?dl=0

    And as you can see in this image, the MP4 does have timecode that is being read by Premiere on the bottom left of frame. TC starts at 10:11:12:13.
