Hi Neil,

I haven't done much videos with IDL, I'd never been very happy with
the results. What I've used is FFMpeg, first I save the frames on
jpeg (or other format you like) and then make a video with ffmpeg in
your favourite format. Ffmpeg is opensource and offer a big list of
formats (http://en.wikipedia.org/wiki/FFmpeg).

In linux what I do with image-0000.jpg to image-nnnn.jpg is:
ffmpeg -r 20 -b 15M -i image-%04d.jpg film.mp4

Cheers,

David
