Speed Control
0.125× to 16×with pitch preservation.
KineMaster's Speed Control tool lets you slow down or speed up any video clip. Enable Preserve Pitch to keep voices and audio sounding natural at any speed. For smooth speed ramps between slow and fast, use the Speed Curve editor.
- 0.125× to 16× range
- Preserve Pitch: natural audio at any speed
- Speed Curve: smooth transition from one speed to another
- Non-destructive — original clip preserved
What it does
Change video playback speed from 0.125× to 16×, with pitch preservation
The Speed Control slider goes down to 0.125× (extreme slow motion) and up to 16× (time-lapse). Preserve Pitch keeps audio at its natural tone regardless of playback speed. Speed Curve takes it further with a curve-based editor that lets you create smooth speed ramps. Accelerating or decelerating with a cinematic feel rather than a hard cut to a new speed.
- 0.125× to 16× range
- Preserve Pitch: natural audio at any speed
- Speed Curve: smooth transition from one speed to another
- Non-destructive — original clip preserved
How to use
Two ways to manipulate time
Speed Control sets a single constant speed. Speed Curve lets you vary speed within a clip for cinematic ramps.

Smooth Speed Ramps
Speed Curve goes beyond a single constant speed: add control points on a curve and drag them to accelerate or decelerate within a single clip. It's ideal for cinematic transitions and music video ramps.
- Step 1
Open Speed Curve
Tap a video clip and tap Speed Curve.
- Step 2
Use a Preset Curve
Select from one of seven Speed Curve presets.
- Step 3
Make a Custom Curve
Add control points on the speed curve by tapping. Drag points up to accelerate and down to decelerate.

Use cases
Three ways to use Speed Control
From dramatic slow-motion reveals to cinematic speed ramps.
Time-lapse cutaway
Speed up a long clip to 8× or 16× for a quick time-lapse of a process, commute, or sunrise — no separate time-lapse app needed.
Cinematic speed ramp
Use Speed Curve to build tension before a music drop: slow the clip down before the beat, then accelerate through it for a dynamic transition popular in travel and music videos.

Frequently asked questions
Quick answers about speed range, pitch preservation, and the difference between Speed Control and Speed Curve.
What is the slowest speed available?
0.125× (one-eighth speed). At this setting, one second of footage plays back over eight seconds.
What is the fastest speed available?
16× (sixteen times regular speed). One minute of footage compresses to roughly four seconds.
Does Preserve Pitch work at all speeds?
Preserve Pitch works across the supported speed range (0.125× to 16×) to keep audio at its natural pitch.
What is the difference between Speed Control and Speed Curve?
Speed Control sets a single, constant speed for the entire clip. Speed Curve lets you vary the speed within a single clip using a curve editor, ideal for ramps and cinematic transitions.
Is speed adjustment non-destructive?
Yes. Speed settings are applied on top of the original clip and can be reset at any time.
