This is the result we'll create: a sandwich recorded in front of a green screen, now floating and spinning in the middle of a bustling night market, with clean edges and soft shadows. Let's get started. Hello, welcome back to the complete Adobe After Effects series from Cerdas Inovasi Digital. Module 12 covers keying and rotoscoping, which is the method of separating an object from its background. We start with green screen keying using Keylight, the built-in keying effect in After Effects used in the film industry. Create a composition from the green screen sandwich footage.
Import the night market footage and place it below the sandwich. A green screen is chosen because its color is farthest from skin tones and most objects, making it easier to separate.
Select the sandwich layer, then apply the Keylight 1.2 effect from the Keying category. Click the screen color pipette, then click the green area near the sandwich. The green background disappears instantly, and the night market is visible behind the sandwich. The initial result looks good, but we need to check it.
Change the view to screen matte. White means the object is fully visible, black means transparent. Gray areas in the background or inside the sandwich are a problem.
Increase the back clip to 15 until the background is completely black, then lower the white clip to 85 until the sandwich is solid white. Don't overdo it, because the edges will become hard. Then return the view to the final result.
Press the 'es' key and scale the sandwich to 70%, then lower its position slightly. Add a drop shadow effect with opacity 40%, distance 20, and softness 30 so the sandwich doesn't look flat. Preview Rotation
The sandwich slowly spins in the middle of the night market with clean edges. A good keying result is always checking the screen matte, not just the final result.
Done We have already composited green screen footage onto a new background, using key light with screen color pipette, reading screen matte, setting block clip and white clip, then placing the object with the shadow. In the next episode, we'll clean up the key result more thoroughly. Need a promotional video, logo animation, motion graphics for social media, Or visual effects for short films?
