When I started using windows movie maker and making videos, everything was totally fine, but it wasn't working well for long. After a while, I started making more videos and when I previewed each video slide, the videos were shaky/twitchy. I've looked everywhere to see if anybody else had this problem but I cant find any! So I am hoping one of you might have the same problem or you know how to fix this. Also this has nothing to do with a camera by the way, Its just videos i uploaded and trimmed them into another video with music added. Thanks :)
