When using windows movie maker after so long all the pics on my timeline become unfound?
On movie maker, that happened to me too. Where ever a picture or video is (the location, such as in a certian folder) you have to leave it there in order to keep working on your movie. Once you’re all done and save your movie to the computer (where it can no longer be edited) you’re safe do move the pictures. But while you’re editing, just make sure all the pictures stay in the same place until you’re done. Sadly, you will probably have to start over with what you were working on when you lost the pics you’re talking about. If you have anymore questions about moviemaker, or if my answer was worded weirdly, just ask me!
