Natural-sounding audio
“Normal pitch” changes the speed of the sound without making voices sound high or deep. “Change pitch too” speeds up or slows down the sound like a tape. “No sound” removes it.
Smooth playback
The result plays at 30 frames per second. Sped-up videos skip frames and slowed-down videos repeat them, so playback stays smooth on every device.
