adobe after effects has paint bucket tool WORKS on video footage. need to keyframe things. this is no keyframing. this is also 8 fps and quarter quality. looks alright in real render. might be helpful to use camera in 4k filming instead of 1080p for crisper lines. mirror phone app im using doesnt use 4k it only goes up to 1080p but i dont think its too difficult to make a phone app that films 4k mirror image and displays on screen. filming pretty far back atm phone is bout 1cm from eyeball
