Since my tutorials tend to be rather long, I decided to start a tutorial series called 'Quick VFX'. In this series I will be showing you awesome visual effects that you can create quickly and easily in After Effects!This first Quick VFX tutorial is in response to everyone asking me how I created the blood smear effect in my After Effects Bullet Hit Tutorial. This is the blood smear effect we will be creating in this tutorial.
All you need to create this effect is your actor pretending to be hit by a bullet while standing in front of a wall. I took a simple clip of myself up against a wall.
One thing I like to do for any sort of bullet hit effects is to apply a Time Remapping effect to the footage to speed up the moment of impact. Not only does it cover up my awful acting but it also makes the bullet impact look a lot more sudden and powerful.
By placing this layer on top of the blood hit, it will appear as if the blood sits behind your actor on the wall.
Add a blood burst effect on top of your actor to add some impact to the bullet hit effect.
I duplicated this blood burst layer, darkened it and blurred it out so I could place it behind the actor to simulate a simple shadow for the flying blood. This will add some depth to the effect.
Finally I added a small smoke puff effect on top of all my layers and tinted it red so it looks like a fine blood mist that shoots out when the bullet strikes.
And we've completed the first part of the effect - the bullet hit.
It's already quite a cool effect, but let's get to what you're actually here for: smearing the blood along the wall your actor slide down.
