Final Cut Pro – Two Fast Ways to Move a Clip Between Tracks
A keyboard shortcut or mouse click can move a clip between tracks.
First, here’s the keyboard shortcut: to move a clip up or down between tracks, select the clip and hold down the Option key while also pressing the Up or Down Arrow key. Up moves the clip up a track and Down, not surprisingly, moves it down.
Here’s the mouse move: press Shift and drag the clip you want to move. Shift constrains the clip so it only moves vertically and doesn’t get out of sync.
