Playing Back a Sequence with Graphics
You can playback the sequence and preview the synchronized graphics at any time. A setting determines whether the preview uses rendered graphics or a representative frame (see
Using the Single Image Preview Setting).

Only timed graphics are rendered and displayed in the Media viewer when you play back a sequence. Untimed graphics are not shown.
To play back a sequence with graphics:

In the Media pane, click the Play button.
If rendering is not complete, the Media viewer displays the message “Graphic not ready.”
