How to Make A Split Screen Video in After Effects?

Let's create a composition where we split the screen into three separate parts and display some footage in them.

Step 1: Create a composition and import three videos to use in each part.

Step 2: Use the shape tool to create 3 boxes which we'll be masking later. You could do less or more depending on how many times you want to split the screen. The key is to make sure they're all equal in size or your end footage will look bad.

Step 3: When you have 3 rectangles, go to your work area and bring each piece of footage under a rectangle.

Step 4: Find the Track Matte setting in your work area and select Alpha Matte for every footage. What it does is, it makes sure your footage is only visible where you placed the shape.
