My favourite delivery format for animations is FLC.
I have written a WWW page with a few notes on the pros & cons of different
animation formats. The page is a bit sketchy but if you want to read it, see

After using the new and improved MPEG features in 5.4 I suggest brewing your
own animation. The improvements are much appreciated but the MPEG
compression scheme isn't really designed for the types of animations created
from within IDL.
Try it, if you are unhappy with the results write a PNG image for each frame
and use a program to string them together. I have used videomach on windows
(a shareware program) to create .avi files with great success but there are
many other programs that can do this.

Yes, I just discovered this in front of an IDL class
the other day. I don't think it was widely advertised. :^)
Anyway, IDL will provide the license for the asking.
Guess they want to get a solid count for the license
fees. :-(
Cheers,
David

Sorry, I found the tech-tip on RSI's site:
Article Title: Information for customers requiring use of MPEG in IDL5.4
Article ID: 3050
Article Name: FILEIO131
Products: ENVI: 3.4; IDL: 5.4
OS Platforms: MACINTOSH; UNIX; VMS; WINDOWS
Last Updated: 11/02/2000
TOPIC:
RSI will pay the required registration fees for those customers who require
the use of MPEG animations in IDL5.4. This will apply to any Research
Systems product that uses IDL5.4, such as ENVI3.4.
DISCUSSION:
In order to receive your updated license, simply send an email to
support@ResearchSystems.com with either:
a) Your name and License Installation Number
or
b) Your name and a copy of your license information
NOTE: Please put "MPEG Request" on the Subject line.
