Playblasting shots in the Camera Sequencer creates a movie clip of the shot’s camera over the entire shot range. By default, the movie is automatically posted to an image plane on the shot’s camera.

By default, playblasted movies are saved to your Movie project location. (This is set in the Edit Projects dialog box. See File > Project > Edit Current.) If there are multiple directories set in the Movie project location, Maya uses the first location listed. You can also change the Directory in the Playblast Shot Options or Playblast Sequence Options to change where movie files are saved.
