This is probably beyond the scope of DSpace. The best that an autonomous process could do for video is probably to extract the first frame and shrink it. That might not be a very good choice -- the first frame might not have the titling or anything else representative of the whole. The best I can come up with is to load the video into an editor, pick a frame that would make a good thumbnail, export it as a still image (JPEG, PNG), resample to an appropriate size, and add that to the Item as the thumbnail. Or the people who made the video may have prepared still images for promotional purposes -- ask them. There are probably a lot of tools that can export frames from videos. I just tried VLC (a player) and Cinelerra (an editor) and both worked well. -- Mark H.
