Sure. But it's a question if Emacs development should rely on something
like youtube, and if it is only for demonstration stuff. Also some
people don't like to run nonfree javascript code on their side. That's
why I'm looking for something better than "any".

Thanks for sharing. I think I'm doing something similar with shotcut,
though I need a mouse. I can also choose a lot of parameters and the
result is pretty small. I expected an animated gif would be even
smaller, but it seems it is actually much larger (about a factor of 50
or so).
Michael.
