Obscuring a face with the Track Matte Key effect
One of the more popular requests in Law Enforcement is to blur or obscure undercover officers or cooperating witnesses (entirely or just their faces) from surveillance video. Adobe's Colin Smith provides a video tutorial on Adobe TV that shows how to obscure a face using the Mosaic effect and the Track Matte Key effect in Adobe Premiere Pro. He also shows a rough and manual way to do this in After Effects in this video. For a more automated and precise way to accomplish this in After Effects, see this video.
