Video
Make a timelapse or get through a long recording faster, with voices that still sound human.
Source: a Kling sample clip. Right: the same clip at 2×.
I
Pick 1.25×, 1.5×, 2×, 3× or 4×. The new length shows up right under the buttons.
“Keep voice pitch” is on, so speech stays clear and music stays in key instead of turning into a chipmunk track. Want the cartoon effect? Untick it.
The result is capped at 60 frames per second, so heavily sped-up clips still play smoothly on any phone.
