  • how to cover up blood splatter with actor?

    Posted by Piff Aroni on November 20, 2010 at 6:00 pm

    I am using a blood splatter effect on the wall but there is a couple of frames where the actor passes over the blood splatter, and I need the actor to cover the blood splatter and as of now, the blood splatter covers him.

    how can I achieve having the actor cover up the blood instead?

    First, you need to isolate the actor (foreground) from the background. Then, when you’ve done that, you put the layer that just includes the actor over the blood splatter layer, which is on top of the background layer.

    You will probably need to use rotoscoping (frame-by-frame animation of masks) to isolate the foreground from the background.

    This is basic compositing. See this page for some introductory material about compositing.

    Perhaps you should begin here:

    It seems that Dave and I think alike (and I type a bit faster).
