 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.
