Frequently Asked Questions
Will changing speed affect audio quality?
We use FFmpeg's atempo filter which maintains audio quality. With pitch preservation enabled, voices and music sound natural at any speed.
What speed range is supported?
You can adjust speed from 0.25x (quarter speed, making a 1-minute video 4 minutes) to 4x (making a 4-minute video 1 minute).
Can I remove audio when changing speed?
Yes! Use our Mute Video tool first to remove audio, then change the speed of the silent video.
