it's been a long time since i've tried - but i seem to recall photoshop =
being able to save to a mov file - so you could make a droplet that =
would take an image sequence and save out to mov

at least it'd be drag and drop and from what i remember years ago =
photoshop seemed to be pretty decent at working with large folders of =
images (at least in regard to droplets to do image conversions to =
different formats etc)

may be just one more option to try?

the image sequence begins to render very quickly.  Initially AE predicts =
a total rendering time of 30 minutes (for a 20 minute video).  This is =
looking pretty good until about 1/3 of the way through, and then AE =
begins to slow down.  And then it slows down more.  The further through =
the render it gets, the slower it renders.  Eventually it finishes in 62 =
minutes.  But I'd guess that it took about 30 minutes to render the =
first 80%, and another 30 minutes to render the last 20%.  This is on a =
freshly booted 8-core machine with no other apps running, 16GB ram.
