Adding Test Clips to Test Compositions
To add an existing test clip to a test composition, first verify that the Composition Builder tab is selected in the lower panel of the Composition Editor. Locate the test clip that you want to add, and then double-click to add the selection to Track 1. To add a clip to an alternate track, drag and dropit onto an existing track (other than Track 1) or drop it into the gray workspace to create a new track.
Dragging a test clip to the area below the last track of the test composition will add the test clip to a new track.
Test clips can also be added using the clipboard. Find the test clip in the workspace that you want to duplicate and select it.
Click the Copy button in the upper toolbar of the Composition Editor. Then, click the Paste button. The test clip will be placed after the last selected test clip.
The test clip will be placed after the last selected test clip.
