Replying to [comment:13 Technologov]:
> Okay, but 99.5% of my videos work with MP4 container just fine on iPad.
It's the remaining 0.5% that needs to be fixed.
Yes, those with invalid timescales.
> Is there a way to fix "timebase" on MP4 containers ?
Yes, {{{-video_track_timescale}}}
> -video_track_timescale is not a documented option; ffmpeg --help doesn't
even list it
{{{$ ffmpeg -h muxer=mov}}}
> and when I try to use it, ffmpeg can't find output file.
The option needs a value depending on the (actual) frame rate of your
input file, for 30000/1001 fps it would be 30000.
