Does the voice sound higher when I speed it up?
No. The sound is stretched to the new speed while it keeps its pitch, so voices sound natural, just faster or slower.
Change Video Speed
Make a video play faster or slower, from a quarter of its speed to four times as fast, without voices turning squeaky or deep. The video stays on your device.
How to Change Video Speed
- Open your video in the video editor. MP4, MOV and WebM work.
- In the Speed tool on the left, press a speed: 0.25×, 0.5×, 0.75×, 1×, 1.25×, 1.5×, 2×, 3× or 4×. For another speed, type it in Other speed.
- Press play to check it. The time under the picture shows how long the video is now.
- Press Save MP4 at the top right.
Questions
Does the music speed up too?
No. Music added in the Music tool plays at its normal speed over the faster or slower video. The ending you added in the Ending tool changes speed with the video.
Can I speed up only one part?
No, the speed is for the whole video. To speed up one part, save that part on its own with the speed you want, then join the parts with Merge.
Do my subtitles still match?
Yes. Burned-in subtitles move with the picture, and Save subtitles (.srt) saves the times of the faster or slower video.
Is a sped-up video smooth?
Sped up, the video keeps your clip's own frame rate, so it plays smoothly. Slowed down, each frame is shown longer; it doesn't invent frames in between, so 0.25× looks like a slideshow on fast movement.
