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 icon

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 icon

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 icon

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.
