I genuinely think this is the fastest lip syncing technique around - Well, fastest that looks any good.

Features: Voice overs! Thank goodness.
Also: Under 7 minutes long!

I've watched probably every Lip Syncing Tutorial, and I couldn't find anything even close to what I wanted. There's some good stuff, but it's all way too much work. So here's one I stole off Ed Atlin by watching every episode of 'Space Tree the Space Tree in Space' I could.

This technique isn't perfect for everything like professional jobs or drama, but works excellently for comedy and quick projects.

If you want to go all out, really want to spend a lot of time with it, I recommend this tutorial:
