A work around, if you are so inclined is to use QTKit Capture classes and feed images to a published input port. Using a QTCaptureSession and 'preview mode' offers similar (if not the same) performance as Quartz Composers Video Input patch.
Publish an image, and then set the value for the key on your QCRenderer instance, and then call renderAtTime: withArguments: This is a bit more involved that a QCView, but totally doable.
