Detonation Films

I forgot to mention this when we had that presentation on FX with the exploding head. For those who don't have Adobe After Effects or some other program with a blood-gush generator, there's a site where you can download blood, explosions, bullets, and a bunch of other SF stock footage put against solid backgrounds, making it easy to key into you videos. Most of the good stuff costs money, but you can get some pretty good free samples that work well. It's worked well for me in the past.
