Rick,
It seems this message had been ripped from the original thread, so the
context was not clear to me. As you know I recompiled your AVI2IDL for IDL
5.6 and managed to produce MPEG-4 (DIVX) files with it. I just hate the box
that pops up to chose the codec. But I am not a good enough c-programmer to
change this. :-)
The problem with MPEG-1 (included in IDL) is that the quality is rather poor
for scientific presentations, so I really like your solution!
