There's also Carbon.Qt, which are wrappers for Quicktime. I haven't
used these (or Quicktime at all), and can't help with them.
Given the description of QTKit in Apple's developer documentation I'd
say that using QTKit through PyObjC would be the easiest way to
implement the application you want to build.
BTW. I don't understand why you want to avoid PyObjC. Do you also
want to avoid PIL and other libraries?
