Introduction

This is the final result we'll create: an old city square with its blue sky replaced by a dramatic cloudy dawn sky, complete with warm lighting that blends into the buildings. Let's get started. Hello, welcome back to the complete Adobe After Effects series from Cerdas Inovasi Digital. Module 13 covers visual effects or E6FX. We start with a technique that's very commonly used, sky replacement, replacing the sky in a video with another sky. Create a composition from the old city footage.

Step 1: Assessing the footage

The camera is static and the sky is blue and clear with no clouds. A plain sky like this is actually ideal, because its color is uniform and different from the buildings and trees, so it can be separated with a key.

Step 2: Keylight on the sky

Apply a key to the old city footage. With the screen color picker, click on the blue sky. The key is not only for green screen, but for any dominant and uniform color. The sky immediately becomes transparent with holes. Change the view to screen matte.

Step 3: Cleaning up the matte

The sky near the horizon is more pale, so it's still gray. Increase screen gain to 130, clip black to 20, and clip white to 75, until the sky is black and the buildings are dense white. Switch the view back to final result.

Step 4: New sky

Import the dawn field footage and place it below the old city. Enlarge it to 130% and move it up so the cloudy sky fills the holes. The dawn sky now appears behind the tower and the trees.

Step 5: Matching the lighting

The buildings are still lit by the bright blue daylight, even though the sky is dawn. Add Lumetri Color to the old city, temperature at 30, exposure minus 0.4, and highlights tweak. The buildings are now lit by the same dawn light as the sky.

Step 6: Preview

Preview the playback. The dawn clouds slowly move behind the church tower, and the entire scene feels like it was shot in the morning. The key to a convincing sky replacement is matching the direction and color of the light.

Done!

Done. We have reviewed the footage, removed the bright sky, cleaned up the matte, placed the new sky, and matched the building lighting. In the next episode, we will add an API to the scene.
