I've been using windows movie maker to trim and combine videos for quite a while now, and had no issues. But all of a sudden it no longer publishes them. It just says: "Failed to create the output video. Please try again! (The parameter is incorrect. Error creating clip from file.) no matter what I do, it keeps saying that. I've tried changing the video slightly and drastically. Waiting for the problem also doesn't work. Does anyone have any suggestions?
