Apple Motion Basics Video Tutorial 18: Motion Tracking and Hiding a Small Area Dynamically
Last week, we had a visitor from New York City. He said that he was a taxi driver in New York. And he showed me a QuickTime movie to prove it. Then he goes, “You see what the problem is?” Well, I didn’t. He said that he wanted to hide the license tag of his taxi. I thought I could blur the number plate dynamically by placing key frames but that it could take hours to do the job manually. “Wait! Perhaps, I could do it with Apple Motion,” I said. So I launched Motion 3 on my iMac. In a matter of 8 and a half minutes or so, I managed to hide his license tag. After seeing the edited movie, the taxi driver looked content and went back to New York City.
The following video tutorial shows how to use Motion 3 to place key frames and hide a small area dynamically by using a motion tracking function. The original video clip (Producer: Scott McReynolds) used in this tutorial comes from Internet Archive. A sample movie is presented at MacHouse Forums > Video Showcase.
