Quick Answer:
When you stare at your screen because a downloaded clip drags on forever, or a quick tutorial flies by before you can catch the main point, maybe you shot an awesome clip on your phone that begs for a dramatic slow-motion touch, but you aren't sure how to fix the timing.
Actually, you don't need a powerful editing suite just to watch a video faster, nor do you need to struggle with confusing software when you want to export a file. You can change video speed in the following 2 ways:

If you just want to breeze through a long lecture or slow down a fast clip while watching, a simple media player handles the job. Your source file stays safe and untouched on your hard drive.
| Platform | Speed Range | Exports a New File? | Free? | Best For | |
|---|---|---|---|---|---|
| VLC Media Player | Windows/Mac/Mobile | 0.25x - 4x | Watching long files faster | ||
| Video Speed Controller | Browser (Chrome/Firefox) | 0.07x - 16x | Web videos and online classes |
VLC is a free, trusty media player that runs on Windows, Mac, and mobile phones. It lets you change video playback on the fly without altering your video data.
Detailed steps on your desktop computer:
1. Launch VLC Media Player and open your target video file.
2. Click on the Playback menu located in the top menu bar.
3. Hover your mouse over Speed, then pick a faster or slower setting from the sub-menu.
You can also tap the ] key on your keyboard to speed things up or the [ key to slow things down as you watch.)
1. Enjoy your adjusted playback while VLC renders the frames smoothly in real time.
Detailed steps on your mobile phone:
2. Open the video inside your VLC mobile app.
3. Tap once anywhere on the video screen while it plays to bring up the playback controls.
5. Tap the small clock icon in the corner of the screen.
6. Slide the speed marker to your preferred playback rate, then close the menu and keep watching.
Summary: VLC Media Player gives you instant playback control for free on any device, but it cannot save or export a permanent new file. If you try to push lectures past 2x speed right away, your ears will hurt from the high audio pitch, so it is safer to start slow around 1.25x.
If you watch online videos in Chrome or Firefox, a browser extension, Video Speed Controller extension, lets you adjust playback speeds instantly across almost any web player.
1. Open your browser store (like the Chrome Web Store) and install a trusted free extension like Video Speed Controller.
2. Navigate to any website with HTML5 video, such as an online lecture, news clip, or streaming site.
3. Look at the top-left corner of the video player, where a subtle speed indicator box will automatically appear.
4. Tap the D key on your keyboard to speed up playback, or press the S key to slow it down. Press R anytime to reset it back to normal speed.
Summary: Browser extensions give you ultimate hotkey control over web videos without needing to download files. The catch is that they only work inside your web browser and will not help you edit or export local video files.
If you want to create a slow-motion highlight reel or speed up a boring clip to share on social media, you need a dedicated video speed changer. These tools let you change video speed and save a brand-new file to your storage.
| Platform | Speed Range | Keeps Audio Pitch? | Free? | Best For | |
|---|---|---|---|---|---|
| AnyMP4 Video Converter Ultimate | Windows / Mac | 9 presets (0.125x - 8x) | Yes | Free trial / Paid | Clean, high-res 4K/8K exports |
| iMovie / CapCut | iPhone / Mac / Android | iMovie: 0.125x-2x CapCut: 0.1x-100x |
Yes | Yes (with in-app buys) | Quick phone edits and vertical clips |
| Clipchamp / Canva | Browser / Windows | Up to 10x (varies) | Yes | Free tier | Quick online browser edits |
If you work on a computer and want total control over your video quality without dealing with confusing pro software, this is your best option.
1. Download and open AnyMP4 Video Converter Ultimate on your PC or Mac computer.

Click on the Toolbox tab located in the top navigation menu. Find and select Video Speed Controller from the list of available utilities.
2. Click the large "+" sign in the center of the window to browse and open your video file.
3. Pick your desired speed preset from the bottom options: 0.125x, 0.25x, 0.5x, 0.75x, 1x, 1.25x, 1.5x, 2x, 4x, and 8x.
I usually find 0.75x for a gentle slow-motion effect or 2x for a quick time-lapse look the most natural.
Hit the Preview button to check your work, then click the Export button to save your new video speed changer output.
Summary: AnyMP4 Video Converter Ultimate keeps your audio sounding natural (no chipmunk voices!) and exports in high-resolution 4K or 8K. The desktop app requires a paid license, but if you edit clips often, it saves a ton of time and delivers professional results. Avoid cranking speeds past 4x unless you want stuttering movement in your final render.
When you shoot footage directly on your phone and want to slow it down or speed it up before sharing, you can skip the computer entirely. iMovie is the app to speed up video or slow down a footage file.
1. Open the free iMovie app on your iPhone and tap Start New Project, then select Movie.
2. Tap your target video clip in the editing timeline at the bottom of the screen.
3. Tap the Speed icon on the bottom toolbar, which looks like a small speed gauge.
4. Drag the slider to the left to slow down your clip or to the right to speed it up.
5. Tap Done in the corner, then tap the share button to save your final video speed changer file straight to your camera roll.
Summary: iMovie is completely free and right in your pocket for quick phone clips and vertical social media edits. However, rendering heavy video exports can drain your phone battery very fast and cause your device to heat up, so make sure you have enough power before rendering long projects.
Don't want to install software on your machine? You can run a quick video speed changer right inside your web browser. Clideo and Clipchce video speed changer options are can try.
1. Open your web browser and navigate to a trusted free online video speed tool like Clideo (https://clideo.com/change-video-speed) or Clipchamp.
2. Click Choose File to upload your target video from your local computer storage.
3. Select your desired speed multiplier from the side menu options, like 0.25x, 0.5x, 0.75x, 1.25x, 1.5x, and 2x.
4. Click Export or Download to process and save your finished file back to your device. (Note: Some online services require a free account login before you can download a clean, watermark-free video.)
Summary: Online tools require zero software installation and work great for one-off edits on a borrowed computer. The big catch is that large video files take a very long time to upload and download over the web, and free sites often slap unwanted watermarks on your finished exports.
How do I change the speed of a video without changing the pitch?
Use an editor that supports pitch correction, like AnyMP4 Video Converter Ultimate, CapCut, or Clipchamp. Simple basic sliders will often make audio sound like a chipmunk when sped up, but pitch-preserved tools keep voices sounding natural.
How can I speed up only one part of a video?
You need to split your clip first. Cut the video right at the start and end of the exact scene you want to change, and then apply the video speed changer settings only to that middle slice. Tools like Canva, CapCut, and AnyMP4 make this easy.
Can I slow down a video on my iPhone without an app?
Yes! Open your video inside the built-in Apple Photos app, tap Edit, select the video tool, and adjust the playback speed slider to change video speed on iPhone. For deeper editing control, grab the free iMovie app.
What is the best free tool to speed up a video?
If you are on an iPhone or Mac, use iMovie. If you are on a Windows PC, Microsoft Clipchamp is built right in for free. For quick web tasks, try Clideo.
Why does my video look choppy after slowing it down?
When you slow down a normal video, the software has to duplicate existing frames to fill the extra time. To keep slow motion looking buttery smooth, try shooting your footage at a higher frame rate (like 60 fps or 120 fps) before you edit it.
How do I change the playback speed on YouTube or in a browser?
On YouTube, just click the little gear icon in the bottom right corner of the video player and select Playback speed. For other websites, install a browser extension like Video Speed Controller.
What speed should I use for a time-lapse or slow-motion clip?
For a dramatic slow-motion look, try 0.5x or 0.25x speed. For a fun time-lapse effect (like clouds moving or a sunset), try 2x to 8x speed. 0.75x and 2x are generally the most natural-looking adjustments for everyday footage.
Does speeding up a video reduce its quality or file size?
Speeding up a video makes the overall file shorter, which usually results in a smaller file size. However, the actual resolution quality depends entirely on your export settings.
Struggling to figure out whether you need a quick playback tool or a full editor just to change video speed? Here is the bottom line for your choice:
