A fit-to-fill edit is a convenient means for quickly creating a timewarp that exactly fits a pre-determined space in the timeline. You mark in and out points in both the source clip and the record clip, and edit the clip into the timeline. The timewarp is calculated automatically based on the difference between the source and record durations.

If the source clip includes edits such as cuts or transitions, you must choose how you want them treated in the timewarp. To preserve the edits so you can continue to work with them, you create a container for the clip. The timewarp will be applied to the container, and the edits will be preserved. If you choose not to create a container, the resulting element in the timeline is a timewarped, hard-committed version of the source clip. See Containers. In either case, the heads and tails of the source clip are retained.

To create a timewarp using a fit-to-fill edit:

1. Mark a source clip with an in and out point.
2. Mark a record clip with an in and out point.
3. Press H to edit the source clip into the timeline.

   A timewarp is automatically applied to the source clip so that it fits inside the marked area in the timeline.

4. Click Process to process the timewarp.

To create a freeze-frame timewarp using a one-frame clip:

1. Select a one-frame clip in the Source Area.
2. Mark a record clip with an in and out point.
3. Press H to edit the source clip into the timeline.

   The source clip is timewarped to fit into the marked region of the timeline.
