Re: QT Export

What I really want is to export a .qtz file using the
standard QT export APIs, and have it render a movie
using specified aspect ratio and duration.

HOWEVER, based on my research, the only effective way
to export a qtz file with fixed aspect ratio and
duration is to copy frame-by-frame using [QTMovie
currentFrameImage].

The problem with this approach is I cannot fork into a
separate thread because the technique requires movie
playback (done in main thread).

The QUESTION therefore is how can I export a qtz file
using QuickTime APIs in a threaded manner?  Is this
possible?

I think you might be reaching limitations of the QTKit, which might be missing APIs. What you want to achieve is doable AFAIK using the classic C QT APIs (although more complex).
