Hi Haje,
You may be able to push the bitrate of the IDL MPEG encoder to get
acceptable results but the files will be pretty big. I posted regarding
this a few weeks back but the OP never responed with results. I haven't
taken the time to investigate myself.
IDL2AVI is the state-of-the-art. But don't despair, you can set the
encoding parameters once per IDL session and then run without the dialog.
Only one initial interaction then it can run unattended.
Other options would be to find a command line encoder that processes
individual frames. The only one I know of is ppm2fli which takes .ppm
images are creates an 8-bit flick file. Probably not what you are looking
for but something else might exist.

This isn't so easy. What CODEC should they settle on? There isn't a
single, quality CODEC that is supported on every platform IDL runs on. Even
if RSI pays to license an MPEG-4 encoder only a certain % of their customers
would be able to view the files it created.
