While trying to export the screen recording for the previous post I came across this: Getting it to my Mac from the iPhone via AirDrop results in a MOV container. I want an MP4 container, so that’s not good. Let’s try exporting it from Photos.app on macOS instead. Nope, that gives me an M4V. Maybe if I use “Export Unmodified Original”? Well, yes… but as you can see from the filesize, that MP4 is the uncut version with audio – not the trimmed and silenced one I need. So far, so bad. Not because I don’t get what I need, but why are these three different container formats?!

Turns out, of course internally it is an MP4 even in the edited state, so using Documents to access the file and send it to my Mac gives me exactly what I need – and even with a non-useless filename.
