Video speed:Slow & Fast Motion

Fantastic Byte

About this app

Change video speed the easy way — slow motion, fast motion, or a different speed for every part of your clip.

Video Speed Changer lets you speed up video up to 4x for time lapse effects, or slow it down to 0.25x for cinematic slow motion. Pick a preset like 2x or 4x, or drag the slider to any speed in between. Preview the result before you export, so what you see is what you save.
