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 !
