Introduction
This is the result we will create, a cafe signboard that looks properly mounted on the wall of an old building, with a perspective that changes according to the camera movement. Let's get started. Hello, welcome back to the complete Adobe After Effects series from Cerdas Inovasi Digital. Tracking two points only gives position, scale, and rotation. For surfaces viewed at an angle, we need a perspective. The 3D camera tracker tracks hundreds of points and calculates the plane within the video.
Step 1: Track Camera
Create a composition from the building facade footage. Select the footage, then open the Animation menu, Track Camera. The 3D camera tracker effect is added and starts analyzing in the background, then the camera solving stage.
Step 2: Track Points
After it's done, the viewer is filled with colored points. Each point is a feature that was successfully tracked along the clip. The points on the flat wall move together as one plane. That's what we need.
Step 3: Name Board Composition
Create a new composition named 'Papan Nama' with a size of 800x120 pixels. Fill it with a dark green solid and a cream-colored KV19 text. Go back to the facade composition and drag the signboard to the timeline. In the viewer, drag the selection box to select the group of points on the facade wall, avoiding the tree and car below.
Step 4: Select Wall Plane
A target circle appears showing the read plane. This plane is the reference for the signboard's perspective.
Step 5: Attach with Corner Pin
The signboard is given the corner pin effect. Its four corners are placed on the wall strip above the shop's archway, then the plane data fills the corner pin frame in every frame. The signboard now follows the wall's perspective.
Step 6: Preview
Preview the result. When the camera moves closer and looks up, The nameplate scales and changes perspective, as if it were actually mounted. Lower the opacity a bit or use the multiply mode to blend with the wall lighting.
Done!
Done. We've used the camera tracking to read the tracking points to prepare the nameplate composition to select the wall plane and to attach the nameplate using corner pin that follows the perspective.
