Chapter 20. Designer's Corner > Adding the TV Picture

Adding the TV Picture

The Img_14bigSketch images show a big-screen TV that doesn't display anything; in fact, the TV screen is transparent in the source file. Your next task is to fill the TV screen with the FillMovie.mov file, which shows a sequence of still images that should look very familiar since several of them are in the background layer you created. This task would be mighty simple if the still image that contains the TV stayed true to itself and remained still! Since you've animated it, though, you need to track the motion of the TV screen with a Perspective Corner Pin tracker and apply that motion data to the movie file. Even though you've animated the Img_14bigSketch1 layer, After Effects won't let you track the layer's motion, since it's a still image. To get around this, you'll pre-compose a duplicate copy of the layer and track the motion in the new composition.
