Speed Up, Slow Down — Total Control Over Your Video Pace
Pacing is everything in video. A well-timed slow-motion moment adds drama; a sped-up sequence adds energy. Klipa's free speed changer lets you go from 0.25x ultra-slow-motion to 4x fast-forward, all with perfectly synchronized audio — no desktop software required.
Adjust your pace, then take the result further: trim the best segment, compress the output for easy sharing, or add AI subtitles that match the new timing.
What the tool produces
How to Change Video Speed in 3 Steps
Upload Your Video
Drop any MP4, MOV, AVI, MKV, or WebM file — up to 2 GB. The tool works with any video that has visual and audio content. If your file is too large, compress it first.
Set Your Target Speed
Use the slider or preset buttons to choose your speed: 0.25x and 0.5x for slow motion, 1.5x and 2x for fast-forward, or 4x for time-lapse effects. Audio pitch adjusts proportionally so voices stay natural.
Download the Adjusted Video
Your speed-adjusted MP4 is ready in moments. Download it directly or continue editing — create a GIF from the best slow-motion moment, or add your watermark before publishing.
Why Use Our Speed Changer?
Cinematic slow-down
Slow down to 0.25x for dramatic slow motion effects.
Speed Up
Speed up to 4x for time-lapse or fast-forward effects.
Audio Included
Audio speed adjusts with the video — no desync issues.
Fast & Easy
No software needed. Just upload, adjust, download.
CREATIVE PACING MADE EASY
Dramatic slow-motion highlights
Slow your footage to 0.25x for breathtaking cinematic moments — perfect for sports highlights, product reveals, and dance videos. After adjusting speed, burn animated subtitles to add context viewers will love.
Time-lapse and fast-forward sequences
Speed up cooking processes, art creation, or travel footage to 4x for engaging time-lapse content. Then resize the output to 9:16 for TikTok or 4:5 for Instagram without losing the visual impact.
Tutorial pacing optimization
Slightly speeding up tutorials to 1.25x or 1.5x keeps viewers engaged without losing clarity. Remove dead time, then cut remaining silences for a tight, professional tutorial.

Frequently Asked Questions
What speed options are available?
From 0.25x (4 times slower) to 4x (4 times faster). Common options: 0.5x, 0.75x, 1.5x, 2x.
Does audio adjust with the video?
Yes, the audio pitch and speed adjust proportionally with the video speed.
Can I create slow motion?
Yes, set the speed to 0.25x or 0.5x for smooth slow motion effects.
Will quality be affected?
Speed adjustment requires re-encoding, but we use high-quality settings to minimize any loss.
Is it free?
Yes — free to try, and the video downloads free with the Klipa logo. Logo-free: a small one-time payment (Pass) or a Pro plan.
What is the maximum video length?
Up to 5 minutes without an account and 10 minutes with a free account (2 h with Pro). Note: a 4-minute video at 4x becomes 1 minute.
Can I change speed and remove silences at the same time?
They are separate tools for precise control. Adjust speed here first, then run the result through our silence remover to cut remaining pauses.
Will slow motion make my video blurry?
Slow motion works best with footage shot at high frame rates (60fps+). Standard 30fps footage slowed to 0.25x may appear slightly less smooth but resolution is preserved.
Can I speed up only part of a video?
This tool adjusts the entire video uniformly. To speed up only a section, first cut that segment, change its speed, then rejoin the pieces in your editor.
