AI Video Speed Changer
Traditional speed changes produce choppy slow motion and chipmunk-pitched audio. Eliro's AI Speed Changer uses frame interpolation to generate new frames for silky-smooth slow motion and pitch-corrected audio for speed-ups — so your videos look and sound professional at any speed.
- AI Frame Interpolation for Smooth Slow-Mo
- Pitch-Corrected Audio at Any Speed
- Speed Ramping with Keyframes

Why Creators Choose Eliro for Speed Changes
AI-powered speed control that eliminates choppiness and audio distortion
AI Frame Interpolation
Generate new in-between frames using AI. Slow a 30fps video down to 10% speed and get buttery-smooth results instead of choppy frame repetition.
Pitch-Corrected Audio
Speed up a video 2x and voices still sound natural. AI preserves the original pitch while adjusting tempo, so sped-up content never sounds like chipmunks.
Speed Ramping
Create dynamic speed ramps that gradually accelerate or decelerate. Slow down for dramatic moments and speed up for transitions — all with smooth, cinematic curves.
Preset Speed Options
Quick presets for common speeds: 0.25x, 0.5x, 1.5x, 2x, 4x, 8x, and more. Or enter any custom speed value for precise control.
Section-Based Speed Control
Apply different speeds to different parts of your video. Speed up the intro, slow down the highlight, and return to normal for the outro — all in one export.
Time-Lapse Creation
Turn hours of footage into stunning time-lapse videos. AI stabilizes and smooths the accelerated output for professional-looking results.
