Why are you arriving at the conclusion that this requires complex software, rather than just a simple UI that says "Drop video file here" and "Fix It" below? E.g., instead of your conclusion "stick to your walled-garden-padded-room reality where somebody else gives you a video file that works", another possibility is the simple UI I described? That seemed to me the point of the post.
