I have my own creating GIFs
tutorial, but I never thought of using VirtualDub. I should try that.
If you had the ISO, you could have mounted it to your computer using
Daemon Tools. It emulates a DVD drive. Mostly used for installing pirated games and whatnot. However, I might grab the ISO and burn a DVD copy to show to other people. You could also have extracted the DVD contents which is what I think Paul did. Just some facts for ways it could have been used.
Anyways, the anime was okay. It had great battle scenes, but the first part was kind of boring and it switched scenes too much. I guess it was like that so it can fill in on the backstory. What I really like about the anime was the soundtrack. It had a really great soundtrack. Other than that, it was alright. It should have spent more time on Black Rock Shooter and well, there were some things unexplained. Like how did Yomi get to that place?
