This is the final result we're going to create: a window in an old building that now displays a barista making coffee, still neatly framed even though the camera is moving. Let's get started. Hello, welcome back to the complete Adobe After Effects series from Cerdas Inovasi Digital. Replacing the content of a TV screen, phone, or billboard is a daily task for compositors. The key is the corner pin effect for perspective, plus tracking data so the corners move accordingly. Create a composition from the building facade footage, then import the barista making coffee footage and place it on top.
This video will be placed in the middle of the second floor window, right below the balcony.
Apply the corner pin effect to the coffee footage. In the viewer, four corner points appear. Connect the upper left corner to the upper left corner of the window glass, upper right to the upper right, lower left to the lower left, and lower right to the lower right. The coffee video is now folded into the window frame with a perspective.
Move the CTI to the 3-second mark. The camera has moved, but the video remains in place and exits the window. We need motion data from the wall plane so that all four corners move accordingly.
Select the facade footage and run the camera tracking. After the tracking points appear, select the group of points on the wall. We will apply this plane perspective data to the four corner pin points, so each frame has its own corner keyframe.
Lower the opacity of the coffee video to 90% and add a little soft glow. Real glass windows reflect light, so a little transparency makes the image feel like it's behind the glass.
Preview the result. The barista video displays in the window and remains neatly framed when the camera approaches and looks up. The same technique applies to phone screens, monitors, and billboards.
Done. We have manually applied the corner pin with four corners, understood the issue of a moving camera, applied the plane data to the corners, and combined the video with the glass. The tracking module is complete. In the next module, we learn keying and rotoscoping. Need a promotional video, logo animation, motion graphics for social media, or visual effects for short films?
