I need to do a school project, and my group decided we would do a stop motion video. The problem is that, when we try to preview the video, it freezes on us. I don't have any other programs besides WMV, and I don't want to download anything else to make a stop motion video. We have about 150 pictures to make the stop motion. If you have too many pictures, does it make WMV freeze? Thanks in advance!
