P.S.: As an aside, when I run ffmpeg on my machine it issues a
deprecation warning and suggests to use avconv instead. Is it worth
converting animation.py from ffmpeg to avconv, too? The command line
arguments should be virtually identicaly (as far as I know - I only
use it very occasionally, though).
Cheers,

Hi all,
apologies for the delay in getting back to you! The end of last week
was quite busy and I was away from my computer during the weekend.

Yes, this works indeed. Thanks for pointing it out! I had feared that
getting the 'bbox_inches' argument to work at all would be much more
involved.

That would be awesome of course. :)

I like this idea. I have now updated my branch so that the save()
method checks which writer is being used. If it is not a temp
file-based one a warning is issued and the 'bbox_inches' argument is
dropped if it is present (see [1]). Please review and comment. :)
Best regards,
Max
