After Effects and Mocha tutorial
With a bit of creativity this special effect can be an amazingly versatile tool. We will show it with a hand but it can be used in almost any kind of surface. Face, chest, and of course object as well not just humans. The most basic version gives you a lot of opportunities to create spectacles. All you need is a drill, and a tolerance for blood… 🙂
The first part of creating this effect is preparation. You need to make sure your footage is useful. This will also be showed in the video. You’ll see that it can be done using average household items. When recording, make sure you have footage where the surface you want to put the hole into is not there. The background behind the hole will be created from these scenes.
Next comes the tracking of the markers. In the video we use the Mocha tool. It does beautiful work, quickly and precisely. This was you can place new layers on the video that move the same way as the original footage. This is how we put the Bevel effect and the extra blood on it. Plus with the Alpha Matte tool and the data from Mocha you can remove the markers from your video with a few clicks.
When this is done it is time to remove the green parts with Chroma Key. Since we are dealing with a small, well prepaired area with a clear outline all we need is Linear Color Key and Inner/Outer Key.
We hope the video wasn’t too difficult to follow. We tried to keep it simple, but there are always way to make a scene a bit better. If you had trouble understanding some parts or have any kind of question, just leave a comment and we’ll gladly answer.
