Thanks for your reply. I'm sorry if I didn't explain the situation clearly. I've captured images from a video. The subject of the video is never shown completely in a sigal frame. Instead the video does a downward pan from the subject's head to the bottom. I would like to know if there is a way to combine the frame grabs to create a complete single image of the subject. The video is a visualizer which is when a song is combined with inages that are relevant to the song. The song plays as the images are displayed. I hope this clarifies what I'm trying to do. In the mean time I will try what you suggest.
