I'm have to do a special effect for Tybalt Vs. Romeo, and last few times I've tried using detonatinfilms' explosion stock footage, I get it to end up sort of transparent from the chroma key in Vegas.
Does anyone know haow to prevent this? Would I have to chroma key the original effect, then put another chroma key of it with just the Alpha channel underlayed?
Hmm, would doing a screen blending mode help at all? If it's a black background, it'll do. It might work with some blue backgrounds, but I haven't tried it out yet.
Try a luma key, or layer a bunch of the transparent explosions on top of each other.
