I just took about 3000 screen caps of Clone Wars Volume 1. 3000 caps for an hours worth of video. Guh. I'm going to be going through and deleting some dulpicates/bad shots/etc later, but I imagine I'll still probably end up with about 2000 after that.
And when I'm done with that, I'm going to do it all again for Volume 2. Yay.
