MP4/Animated GIF/JPEG woes....(Windows, IDL 8.1) [message #76872]

I've just started collaborating with some planetary astronomers who
tend to use very different tools compared to us traditional
observational astronomers :-) It's fun but I'm trying to generate
products that they use (and I typically don't) and having some teeth-
gnashing moments and screaming at the IDL help pages....

1). Creating an MP4 file from a stream of images - seems easy
according to the help pages and I duplicated the example code. The
resulting file is playable on my windows box using media player, but
not when using QuickTime on either windows or their Mac systems.

2) Animated GIFs again seem straightforward, except that write_gif
appears to reset my color table so I lose the color in overlays over
images. I pass in the current RGB values from the common block after
setting my tables but the gif file is B&W and the RGB arrays are all
reset!

3) Even tried animated JPEG since the help pages describes how to do
it, but the sample code doesn't work as I get an error when trying to
use the unit option even though it is described in the help....

Venting over - if anyone has some suggestions as to what causes any of
these problems or have solved these issues, are please let me know
cheers - Brian
