If you want to create an animation from a video, here’s a few options for you. Both of them require a third-party animation editor, though I’m not going to suggest any. (I use Jasc Animation Shop, which came with a copy of Paint Shop Pro that somebody gave us.)
One of them is Movie To Animated GIF, which is simple, but is very very picky. (Sometimes it won’t open videos, other times the animation comes out choppy.) But it turns it all into a nice animation for you, and all you’ve gotta do is remove the frames you don’t want.
Another alternative is using Avidemux. I’ve already posted about using it, so I’m not going to repeat myself. Although you have to combine the frames yourself, it’s easier to get exactly what you need.
Any other ones (or animation makers)? Post in comments.
