Thanks!

The problem is that I am not _that_ keen on investing a lot of time to
learn ffmpeg.  I have no doubts it is an amazing piece of software (even
if it looks _very_ obscure and the syntax of its CLI parameters is plain
weird - but I think Emacs, which I find familiar and (mostly) logical,
makes a very similar impression on outsiders, so...), but I only need it
for a few very simple scripts...  For me the main problem is that I know
next to nothing about video formats, compression, editing etc., so even
the terms used are sometimes not obvious.

Still, I'll give it a try, and I'll probably ask here again in some time
if need arises.  (Also, if anyone here is interested in things like
this, I can post a link to a blog post describing the thing I'm working
on right now that will use ffmpeg and mpv under the hood when it's
published.)

Best,
