I've tried doing this on both mine and my brother's computers, so I know that it's not just a computer problem. Every time I export a video to my desktop, when I play it, it's way slow and off. The mouth doesn't sync up to the audio like it did when I made the movie to begin with. What's going on?

So I have an animation in which a guy is walking, at frame 240 the video goes back to frame 1.

I have a character drawn but have no idea how to make him walk from the right side of the scene to the left side of the scene.
