Professional Video Speed & Time Control

Master video tempo with professional speed adjustment tools. Create stunning slow-motion sequences from regular footage, compress hours into seconds with time-lapse effects, or fine-tune playback speed for perfect timing. Our advanced processing maintains quality while offering pitch correction for audio, frame interpolation for smoothness, and precise control from ultra-slow to ultra-fast playback. Perfect for creators, educators, and analysts needing complete temporal control.

Speed Features

Adjust video playback speed from 0.25x (quarter speed) to 4x (quadruple speed) with exact control. Create dramatic slow-motion effects for sports analysis, or time-lapse sequences from regular footage. Fine-tune to any speed between with decimal precision for perfect pacing.

Maintain natural audio pitch when changing speed, preventing chipmunk voices or deep distortion. Advanced algorithms preserve voice clarity at any speed, perfect for educational content where comprehension is crucial. Optional pitch shifting for creative effects.

Generate smooth slow-motion from regular footage using AI-powered frame interpolation. Creates intermediate frames for buttery-smooth playback even when slowing down significantly. Perfect for converting 30fps to cinematic slow-motion without choppiness.

Specify exact target duration and let our tool calculate the perfect speed adjustment. Need a 2-minute video to fit in 30 seconds? Or stretch 15 seconds to fill a minute? Input your target and get precise speed calculation instantly.

Frequently Asked Questions

You can slow down to 0.25x speed (4 times slower than original). For even more dramatic effects, you can process the video multiple times. 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. This means you can speed up lectures or tutorials without the chipmunk effect, or slow down without deep distortion.

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 (24-30fps) to achieve that cinematic slow-motion look without stuttering.

Currently, speed changes apply to the entire video. For variable speed effects, you'll need to split your video into segments using our cut tool, apply different speeds to each segment, then combine them. This gives you complete control over pacing throughout your video.

Use our duration targeting feature! Enter your desired final duration (e.g., 30 seconds for Instagram), and we'll calculate the exact speed needed. The tool shows you the required speed multiplier and processes your video to fit perfectly within your time constraint.
