# Description

Use the playRate property to speed up or slow down playback of a movie or sound.

The playRate is the ratio between the desired playback rate and the natural rate of the movie or sound. A playRate of 1 plays the movie or sound at normal speed; a playRate greater than one speeds up the playback; a playRate less than one slows down the playback.

A negative playRate plays the movie or sound backward.

If the playRate is zero, the movie or sound is paused.
