Tips
- Slow motion is great for sports technique, tutorials and catching small details.
- At 1.25x to 1.5x, long lectures and meetings stay easy to follow while finishing sooner.
- Audio pitch may sound odd at extreme speeds — preview before you export.
The new file length is the original length divided by the speed, so 2x halves the time and 0.5x doubles it. Pitch correction is turned off, so voices change pitch like classic fast forward. Recording is real time relative to the new speed.
