Change The Speed of a Clip Not it’s Duration

In Final Cut, there may be times when you want to change the speed of a clip, but not it’s overall duration in the Timeline.

To do this, put your playhead over the clip and press Alt/Opt+Cmd+F. This loads a copy of the clip into the Viewer. There are no In or Out points. Next, go to the Modify  > Speed menu (Cmd+J) and change your speed to say, 30%. Grab your clip and do a Replace edit.

That’s it!

Depending on your footafe, you may want to send the clip to Motion and apply Optical Blending to clean up any ghosting that you get.
