How are you doing the compositing/overlaying?
I dont have any experience with this explicitly, but I would imagine
different types of compositing would have different overhead GPU/CPU
wise.

Hi !
I have a few hi-resolution movies (1920 x 1080) that play smoothly
at full resolution using the techniques shown in QTCoreVideo101
Now, I'd like to overlay a quartz composition on top of these movies.
Whatever I try, the performance is bad. The fps drops
significantely, even if the composition is pretty simple.
Does anybody have some hints / solution / sample-code to share ?
Thanks !
