Frequently Asked Questions

You can slow down to 0.25x speed (4 times slower). With frame interpolation enabled, we generate smooth intermediate frames to prevent choppy playback even at extreme slow speeds.

Not with pitch correction enabled! Our advanced audio processing maintains natural voice pitch regardless of speed changes. You can speed up lectures without the chipmunk effect.

Frame interpolation uses AI to generate new frames between existing ones, creating smoother slow-motion from regular footage. Use it when slowing down video shot at normal frame rates to achieve cinematic slow-motion.

Speed changes apply to the entire video. For variable speed effects, split your video into segments using our cut tool, apply different speeds to each, then combine them.

Use our duration targeting feature! Enter your desired final duration and we'll calculate the exact speed needed. Perfect for fitting content to social media time limits.
