Just like working in a word processor, you can copy and paste frames or entire clips. I use copy and paste when I want to create a new clip out of a selection of frames without breaking up the original clip, in case I want to use the footage somewhere else while I'm editing.
1. | Select a range of frames within a clip and choose Copy from the Edit menu. |
3. | Choose Paste from the Edit menu. |
If no clip is selected before pasting, the new clip appears at the Playhead location, even if that's in the middle of another clip.
