  • How to make ffmpeg remux an iPhone MOV (HEVC) that works on Apple products ?

    21 janvier 2024, par Mikael Finstad

    I want to remux a HEVC file (without encoding). I have tried most options, even removing audio, but I cannot get an output file that plays smoothly with Apple products.

    



    First I AirDrop any MOV from an iPhone recorded with the camera in HEVC.

    



    Then run :

    



    ffmpeg -i IMG_4605.MOV -c copy out.mov


    



    Then if I send out.mov back to the iPhone and try to play it back, it plays back with glitches while seeking, like this : (original to the right)

    



    Result
Original

    



    When I try to drag the file into a new iMovie project and try to play it back, it freezes the whole iMovie app and needs a force quit.

    



    Doing the same with the original causes no issues, so obviously there is something wrong with the way ffmpeg remuxes it, or something wrong with Apple's software.

    If I open out.mov in QuickTime and do a trim and export it, then it it still "broken", so I'm thinking there's nothing wrong with the actual muxing into MOV, because QuickTime is passing the error on.

    



    I noticed that out.mov has different parameters 19200 tbn, 19200 tbc (vs original 600 tbn, 600 tbc). However, if I force set these to 600 with -video_track_timescale 600 the output file is still broken.

    



    Anyone got some insights ?
