Oh, wait, I think I'm wrong on all this. The output framerate actually
isn't set to 24 for the second. It appears that I don't actually
understand this very well.

Please ignore this, sorry for the noise.

Perhaps having (from man ffmpeg-all, image2)
 > ffmpeg -framerate 10 -i 'img-%03d.jpeg' out.mkv
instead of (from man ffmpeg, examples)
 > ffmpeg -f image2 -i foo-%03d.jpeg -r 12 -s WxH foo.avi
or a mixture (both -framerate input, and -r output) would be good in the
ffmpeg(1) page examples, to stop others just reading that and getting in
a mess as I did. I could do the patch if you think it's a good idea.
