In this holidays I've been recording videos and staff. Then I edit them with Ulead video Studio. But I have a problem; in one of those videos I want someone to appear twice in the same scene. So I did the overlay effect, but the only way to do it was to apply a 50% transparency so both appear as ghost in the scene. I would like to know if there's a program that could easily crop a group of frames, in this case in half so I can do the overlay, but without the transparency, and achieve a nice effect. Till now the only program I found to do this was Ulead Gif Animator but I think it's not really designed to do this kind of job.
