hmm not entirely sure what your asking for but if your looking for blood animations to play ontop of your finished animation via video editor. I know of a particle creator that can create blood animations and many more pretty easily.

Or if your looking for a blood texture to animate yourself? I can create one for you
what exactly are you looking for?
Below is a quite 2min make of a blood splash using one of the defualt animations of the particle creator
