I'm pretty sure that's exactly what QCTV does: all you need is
remove the real-time part.

I really like your advice, and what you describe about going
straight from a QCRenderer to a .mov frame by frame is exactly
what I want to do. I am just really having trouble finding any
documentation on how to do this. Any chance you would mind
linking me to an example that you can think of?
Thank you very much,

1) .mov files made with QCTV do not open properly in Final Cut Pro.
Those are standard .mov files, so that's surprising: have you
tried changing the codec?
2) QCTV's way of exporting an mov requires the exporting to take
real
time. For our application this could be over 30 minutes.
You can just change the code to make it non-real time: use a
QCRenderer to render the composition frame by frame to a .mov.
These issues and a few more that are less significant make me think
that there has to be a better way to do this. Does anyone know a
better way to programmatically export a .mov?
You can also use QT APIs directly or maybe even QTKit and open
the .qtz file as a QT movie and use those APIs to transcode it to
a .mov with a different codec. There might be APIs that allow you
to transcode movies using only a few calls.
