I ripped a video off Youtube and played around with the 8-point garbage matte in FCP – obviously very rough, but I wondered if this is starting to get ballpark:

I haven’t done this before – I know it’s very basic! Keen to hear advice on the technique though if anyone knows more and has the time to talk about it. I’ve read you can get a free 64-point garbage matte plug-in, which would neaten the trailing ‘ghost’ images, and given enough time I’d keyframe the garbage mattes around moving footage, rather than the freeze frame… Obviously best to shoot static with no movement in the background…. what else?
