        I need to record an modified camera screen, i.e. detect some objects, mask them and save that masked video.


        All samples I was looking at only demonstrated how to record a video, live detect some features and display the detected features.

        i.e. use  captureOutput(_, didOutput:from:) to modify the sample buffers and use that as AVCaptureInput for an AVCaptureSession


        Has anybody an pointer where to look?


        Another Q: What happens when a AVComposition is saved? Is the original video stream recorded and an effect track or is the video stream "rendered down"?
