How to Speed Up or Slow Down Video in Premiere Pro

A workflow taught by Adobe Certified Instructors at Adobe Video World.

Slow motion adds drama; fast motion adds energy. Premiere Pro gives you several ways to change clip speed, from a quick percentage change to silky speed ramps. This guide covers all of them — plus the setting that makes slow motion look smooth instead of stuttery.

Change Speed with Speed/Duration

The simplest method: right-click a clip and choose Speed/Duration. Enter a percentage — 50% plays at half speed (slow motion), 200% plays at double speed (fast motion).

Check Maintain Audio Pitch if you want speech to stay natural-sounding, and Ripple Edit so the timeline closes the gap when the clip changes length.

Use the Rate Stretch Tool

To change speed by dragging instead of typing, grab the Rate Stretch tool (shortcut R) and drag a clip’s edge. Stretching it longer slows it down; squeezing it shorter speeds it up. It’s perfect for fitting a clip to an exact gap in the timeline.

Make Slow Motion Look Smooth

Here’s the setting beginners miss. When you slow footage below the frame rate it was shot at, Premiere has to invent frames — and by default it just repeats them, which looks stuttery.

In Speed/Duration, set Time Interpolation to Optical Flow. Premiere then analyzes motion and generates smooth in-between frames. For best results, render the clip afterward. Note that Optical Flow works best on simple, clean motion — it can smear over complex movement.

The golden rule: for true, crisp slow motion, shoot at a high frame rate (60, 120, or 240 fps) and slow it down in a standard 24 or 30 fps timeline.

Create a Speed Ramp with Time Remapping

A speed ramp — where footage glides from normal speed into slow motion and back — is the signature look of modern action and travel videos. It uses Time Remapping:

Right-click the clip’s fx badge and choose Time Remapping > Speed.
A horizontal rubber band appears across the clip. Ctrl/Cmd-click it to add speed keyframes.
Drag a segment of the band down to slow it or up to speed it up.
Drag the keyframe halves apart to create a gradual ramp between the two speeds.

Match Speed Changes to Your Edit

Speed changes feel best when they hit the beat of your music or the peak of an action. Time a ramp into slow motion right as something dramatic happens, then ramp back out on the next beat.

Pair your speed effects with clean transitions and finish with the correct export settings for smooth, high-frame-rate playback. Used with intent, a single well-placed speed ramp can make an edit feel cinematic.

How to Reverse a Clip

Playing footage backward is a fun creative trick — perfect for un-pouring a drink or rewinding an action. Right-click the clip, choose Speed/Duration, and tick Reverse Speed. You can combine it with a percentage change to create a reversed slow-motion effect.

Remember to mute or replace the reversed audio, since speech played backward rarely sounds the way you want.

Speed Up Audio Without Chipmunk Voices

Speeding up a talking-head clip normally raises the pitch into a cartoon squeak. To speed up the footage while keeping voices natural, tick Maintain Audio Pitch in the Speed/Duration dialog.

This is the secret behind those fast-but-watchable tutorial and vlog edits. For finer control over the result, fine-tune levels and clarity afterward with the Essential Sound panel.

Frame Rate and Slow Motion Explained

Smooth slow motion is really a frame-rate story. A clip shot at 60 frames per second contains twice as many frames as a 30 fps clip, so when you drop it into a 30 fps timeline and slow it to 50%, every frame already exists — the result is buttery smooth with no guessing.

Slow a clip below the frames it actually contains and Premiere has to invent the missing ones. That’s why the rule is simple: decide you want slow motion before you shoot, and film at a high frame rate. Capturing at 120 or 240 fps gives you dramatic, crystal-clear slow motion that no software trick can fully replicate.

Create a Freeze Frame

A freeze frame holds a single moment — great for introducing a person or punctuating an action. Park the playhead on the frame you want, right-click the clip, and choose Add Frame Hold, or use Frame Hold Options for more control.

Premiere splits the clip and freezes that exact frame for as long as you like. Combine a freeze frame with a title and a sound effect for a confident, stylish reveal that instantly elevates an intro.

Time Speed Changes to Music

Speed effects feel intentional when they land on the beat. Drop markers on your timeline at the key beats of your music (press M while it plays), then build your speed ramps so the slow-motion peak hits right on a downbeat and ramps back out on the next.

This rhythmic timing is the secret behind polished travel films and action edits. Finish the sequence with clean transitions and a balanced audio mix so the speed changes feel like part of the music, not an afterthought.

Creative Ways to Use Speed Changes

Speed is not just a technical fix — it is a storytelling tool. Used with intent, a change of pace can completely shift the emotion of a scene.

Slow-motion reveal — drop into slow motion as your subject turns to camera for a confident, cinematic introduction.
Fast-motion montage — speed up a long process such as cooking or building to compress time and keep energy high.
Speed ramp on impact — ramp into slow motion at the peak of an action, then snap back to normal speed for emphasis.
Hyperlapse — combine fast motion with movement through space for a dynamic sense of travel.

The best edits mix speeds deliberately rather than constantly. One well-timed ramp says more than a whole timeline of speed effects.

Plan Speed Changes Before You Shoot

The most cinematic slow motion is decided at the camera, not the keyboard. Whenever you anticipate slowing footage down, film it at a high frame rate — 60, 120, or even 240 frames per second — so every slowed frame already exists and the result is perfectly smooth. Optical Flow can rescue a standard clip, but nothing matches footage shot for slow motion from the start.

Think about pace in advance: where you want energy, where you want a dramatic beat to land. Bringing that intention to the shoot makes your speed ramps feel like part of the story rather than an effect bolted on afterward.

For the smoothest slow motion from standard footage, generating new frames with optical-flow Timewarp beats simply slowing a clip down.

Ramping reps into smooth slow motion is a signature move in editing dynamic fitness videos.

Time-lapsing a long bake or prep is a staple of editing cooking and recipe videos.

Key Takeaways

Use Speed/Duration for a quick percentage change, or the Rate Stretch tool to drag.
Set Time Interpolation to Optical Flow for smooth slow motion.
Shoot at a high frame rate for the cleanest, most cinematic slow-mo.
Use Time Remapping to build gradual speed ramps that hit the beat.

Frequently Asked Questions

How do I slow down a clip in Premiere Pro?

Right-click the clip, choose Speed/Duration, and enter a percentage below 100% (for example 50% for half speed). Set Time Interpolation to Optical Flow for smoother results.

Why does my slow motion look choppy?

Premiere repeats frames by default. Set Time Interpolation to Optical Flow in Speed/Duration so it generates smooth in-between frames — and ideally shoot at a high frame rate.

How do I make a speed ramp in Premiere Pro?

Use Time Remapping: right-click the clip’s fx badge, choose Time Remapping > Speed, add keyframes to the rubber band, and drag the keyframe halves apart to ramp gradually between speeds.
