Speed up or slow down video

In the timeline, select the clip you want to speed up or slow down.

To show the speed controls, click the Speed button on the right bar. 

(Optional) To speed up or slow down only a portion of the clip, set the start and end points to select a specific range.

• Set the start and end points using the Range slider in the Speed panel, or 
• Set the start and end points directly using the blue range handles on the clip in the timeline. 

Move the Range Speed slider right to increase the playback speed of a clip. Move it to the left to slow it down. As you move the slider:

• The clip duration changes (under the Range Speed slider) 
• A sped up clip becomes shorter in the timeline. A slowed down clip becomes longer.

If the clip contains audio, playing the clip more slowly lowers the pitch of the audio, and playing the clip faster raises the pitch. To preserve the original pitch of the audio, the Maintain Audio Pitch check box in the Speed panel is enabled by default. If you don't want to preserve the pitch, disable this check box.

Tip: If the audio isn't essential, mute the audio track and add background music to the clip.  

To smooth the transition into your speed range, select Ramp and adjust the ramp duration.

In the timeline, select the clip to which you want to apply speed changes..

To show the speed controls, click the Speed button on the right bar.

In the Clip Duration field, click the minutes, seconds, or frames values and type in your changes.
