I have tried to include the source video as a patch in the interactive quartz composition, by clicking on the composition for example I can add circles, squares, cubes etc to the visual content. It more or less works after I have built a movie controller to move back and forth in the composition time line but when I stop the composition, everything becomes black. I find this cumbersome and would rather use the QTKit classes to deal with the video and capture the user interactions at the quartz composition level. So what I thought of doing was to add a QTView object and a Quartz Composer view to the interface, making the composition transparent and putting it on top of the QTView. The problem in that case is that the QTView always masks the Quartz composition.
You could use CoreAnimation to layer the QuartzComposer content with the QTKit content. This will fix the "masking" issues.
