Step 2ARight-click on the chosen layer and select "Time" from the context menu, then choose "Time Stretch". In the new dialog box, lower the percentage value of "Stretch Factor" to speed up the clip.

You can also select from the options under "Hold in Place" to stretch time from a certain point.

Step 3After that, press the "Spacebar" to watch the result. You can adjust the stretch factor again as needed.
