Around 4 years ago, I made my first amv. It used footage of Dragon Ball Z and Soul Caliber 2. I actually recorded the soul caliber 2 scenes with my digital camcorder.
I released 4 videos and partook in 3 released MEPs over the course of 6 months 4 years ago. I've edited every now and then since and still have a few ideas I'd like to try, but haven't bothered to work on anything for awhile.
