Playback Controls

The controls illustrated below play through the script according to the Time Bar frame

range, not the global timeRange.

• To play forward, click the forward arrow button.

• To play backward, click the backward arrow button.

Note: Regardless of the speed of your computer, Viewer playback is now limited to

the frame rate specified in the framesPerSecond parameter in the Format section of

the Globals tab.

Assuming your composition is cached so that real-time playback is possible, this

playback rate is not exact, but may vary by around 10 percent.

• To stop playback, click the stop button, or click the left mouse button anywhere on

the screen.

• Shift-click a playback button to render all frames in the current frame range and store

the frames in memory. The sequence will play back much faster next time.

• Click the keyframe buttons to jump to the previous or next keyframe.

The following table lists additional keyboard shortcuts.
