About Trimming
 
 
 

Trim a clip to add frames to, or remove frames from, a clip's head or tail. Slide a clip to trim the clips before and after it without changing the frames used in it. Slip a clip to offset the frames in a clip without trimming the clips before or after it. Backdraft Conform keeps track of the source material that goes into trimmed shots, so you can go back and reintroduce material you had previously trimmed out.

You can trim using hotkeys or gesturally. Gestural trimming can only take place when the Trim button is enabled in the Editing menu. To trim from the Record Area, it must be displayed in one of the following views:

Hotkey trimming is available in Timeline, Head/Tail, and Trim View modes regardless of the status of the Trim button.

The viewing modes are described in Editing Essentials.
