Using the Roto Brush tool in Adobe After Effects CS5

Article Description

This excerpt from Adobe After Effects CS5 Classroom in a Book shows you how to use the new Roto Brush tool in After Effects CS5, which is much faster than conventional rotoscoping, and for movies with complex backgrounds, much easier than keying.

Adding audio

All that is missing now is the audio file. You imported it earlier, so you just need to add it to the Timeline panel.

  1. Drag the VO.mp3 file from the Project panel to the bottom of the layer stack in the Timeline panel.
  2. Go to 0:17. With the VO.mp3 layer selected, press the [ (left bracket) key to reposition the layer to start at 0:17.
  3. Choose File > Save to save the finished project.
  4. Make a RAM preview to view the final project, or render it according to the process described in Lesson 14, “Rendering and Outputting.”
