Introduction

This is the result we'll create: a smooth gradient sweep transition from a rocky river to mountain reflections in a lake, controlled by the dark brightness of a gradient layer. Let's get started. Hello, welcome back to the complete Adobe After Effects series from Cerdas Inovasi Digital. Luma Matte uses the brightness level of the matte layer, not its transparency. White means visible, black means hidden, and gray means partially visible. We use this to create a soft transition.

Step 1: Two Footages

Create a composition that lasts 8 seconds. Insert the rocky river footage below and the reflective lake footage above it. The lake will appear replacing the river through the transition.

Step 2: Gradient Solid

Create a solid the same size as the composition named 'gradasi' above the lake footage. Apply the gradient ramp effect, start color black on top and end color white at the bottom. The solid now contains a gradient from black to white. In the track matte column for the lake footage, select 'gradasi' and change its type to Luma Matte.

Step 3: Luma Matte

The lake appears visible at the bottom white area, fading out to the black top. The gray in the middle creates a soft transition, something that alpha matte on a solid cannot achieve.

Step 4: Sweep Animation

Select the gradient layer and animate its position. At second 2, start of RAM at 1080 and end of RAM at 1480, so everything is black and the lake is hidden. At second 5, start of RAM at minus 400 and end of RAM at 0, so everything is white. The lake sweeps in from bottom to top with a soft edge.

Step 5: Luma Inverted Matte

Change the matte type to Luma Inverted Matte. Black and white are swapped, now the lake appears from the top, sweeping in the opposite direction. Inverted Matte is useful when the gradient or footage matte is reversed from what we need. Switch back to Luma Matte.

Step 6: Preview

Play the preview from second 1 to 6. The river slowly gets replaced by the lake with a soft, mist-like sweep. Replacing the gradient ramp with fractal noise will create an organic textured transition.

Done!

Done! We have now understood the difference between alpha and luma matte, created a gradient solid with a gradient ramp, used a luma matte, animated the sweep, and tried a luma inverted matte. In the next episode, we create a split screen with a mask. Need a promotional video, logo animation, motion graphics for social media, or visual effects for a short film?
