I used to have an Apple Script that worked pretty well for compiling =
image sequences, check around the Apple Script forums.

I actually never render them any more from AE as they are such a pain to =
re-compile, I render to multiple QT files, I have often rendered out 100 =
QT files which may seem excessive but it gives the flexibility of an =
image sequence but is much quicker to re-assamble.
