Frequently Asked Questions

What happens to audio when I change speed?

Audio speeds up/slows down with video. You can optionally remove audio or maintain pitch at different speeds.

What's the best speed for slow motion?

0.5x is subtle slow-mo. 0.25x is dramatic. For smooth results, source video should be 60fps+ for very slow speeds.

Can I speed up parts of a video?

This tool changes speed for the entire video. For variable speed, you'd need to split the video first.
