Learn how to adjust the playback speed and duration of clips in Adobe Premiere and use audio stretching modes to maintain audio quality.
Try the app
Follow along with any project to learn how to adjust the playback speed of video clips.
Before you begin:
Import your video clips into a Premiere project and add the clips you want to modify to the timeline.
Select Clip > Speed/Duration from the menu bar. Alternatively, right-click the selected clip(s) and select Speed/Duration.
In the Clip speed/duration dialog box:
- Enter a percentage in the Speed field to change playback speed. (100% is normal speed, lower values slow down, higher values speed up)
- Select Reverse speed to play the clip backwards.
- Select Lock pitch and speed to adjust audio pitch and speed together. When unselected, pitch and speed can be manipulated independently.
- Select Ripple Edit (shift trailing clips) to automatically adjust the position of subsequent clips in the timeline.
Select the linkicon between Speed and Duration to unlink the settings. Then adjust the value you want to change.
Select OK.
Play back the video on the Program Monitor to see the changes you have made to the speed and duration of the clip.
Adjust audio stretching quality
When changing the speed or duration of a clip containing audio, select an audio stretching mode to control the quality of the resulting audio.
Choose one of the following options:
- Rendered - Medium Quality: Uses high-quality audio stretching to help preserve natural-sounding audio when changing clip speed or duration. This is the default mode for newly stretched clips.
- Rendered - High Quality: Uses high-quality audio processing for stretching or compressing audio. Select this option when audio quality is a priority.
- Legacy: Processes audio in real time without requiring rendering. Use this option for immediate playback feedback. Significant speed changes may introduce audible artifacts.
Catatan
Medium Quality and High Quality require rendering and may take additional processing time compared with Legacy.
Choose an audio stretching algorithm
Premiere automatically analyzes the audio content and selects an appropriate stretching algorithm.
You can also choose an algorithm based on the type of audio:
- Monophonic: Suitable for dialogue and sound effects.
- Polyphonic: Suitable for music and ambience.
Use Audio Auto-Tagging to have Premiere select the appropriate algorithm based on the audio content.
Adjust audio pitch
Use the pitch controls in the Clip Speed/Duration dialog box to adjust audio pitch when changing clip speed or duration.
The high-quality audio stretching modes support pitch preservation, helping dialogue and music sound more natural when stretched or compressed.
Set time interpolation
To control how Premiere generates video frames when changing clip speed, select a Time Interpolation option in the Clip Speed/Duration dialog box:
- Frame sampling: Repeats or removes frames to adjust playback speed.
- Frame blending: Blends adjacent frames for smoother motion.
- Optical flow: Analyzes motion between frames to generate intermediate frames for smoother slow-motion playback.
Select OK to apply your changes.
Play the clip in the Program Monitor to review the updated speed, duration, and audio quality.
