How to Speed Up or Slow Down Video on Windows 10

How do you speed up video in Windows 10? If you want to speed up a clip of your video to mark a transition, or slow down a clip to focus on it, then that’s what you’re going to learn today!

Also, it’s worth mentioning we’re going to be using 2 different methods for this (both options are available for Windows 10), so let’s start with the first one…

1: Choose a Video Editor

When it comes to Windows 10 video editors, there are many options available, but you need to be careful when selecting one, as there are many who are meant for people that are experienced with video editing software.

That’s not the case with FilmForth, a free video editing app that’s really simple to use. It can be installed with 2 clicks, and, contrary to most free editors, FilmForth is watermark-free, so you won’t have any annoying watermarks when watching your final video.

To start downloading FilmForth, click on the button below.

If you don’t want to install any apps though, then you can use Kapwing to speed up or slow down your video (like we’ll do in the second part of this tutorial), but take into account that it has less editing options than FilmForth.

Also, FilmForth won’t affect your PC performance as it’s a very light app, so why don’t you give it a try?

Once FilmForth has finished installing, it’s time to continue with…

Step 2: Upload Your Video Clip

To open up your video clip in FilmForth, right click on the video file you wish to edit, and go into “Open With” > “FilmForth”

However, if you want to create a Project so that you can save your progress and continue editing or changing the video’s speed in the future, you’ll need to open up FilmForth and select the “New Project” option as shown below.

Once you’ve created the project, you’ll need to add the video file by clicking on the “+” icon that’s located on the right on your timeline.

For now I’d recommend sticking to adding just one clip, so you can make sure that you’ve properly changed the playback speed of the video.

Step 3: Select the Specific Video Clip

If you want to adjust the speed of the whole video, then just refer to the next step, but if you want to adjust the speed of a certain part (or clip) then you’ll need to split your video beforehand, so that’s what we’ll be doing here.

To split a certain part of your video, position the red marker on the part where you want to make the split, and click on “Edit” > “Split”

Once you’ve made the first split, you have two options.

If you want to change the speed of the rest of the video, then just leave it as it is. Meaning, you’ll have two parts in your video, one with speed and one without (depending on the one you select).

But if you want to change the speed of a specific part in the middle of your video, then you’ll need to make another split.

For this tutorial, I’m going for the second option, so this is how my timeline is going to look after I’ve done the two splits:

Step 4: Adjust The Speed Slider to Suit Your Needs

The steps to change video speed are really simple.

Simply click on the clip you wish to change the playback speed, and then go into “Edit” > “Speed”. Once you’ve done so, the speed menu will appear:

As you can see, there you can adjust the playback speed of your video to either slow it down or speed it up.

Once you’ve adjusted the video speed, simply click on the “←” button that’s located on the bottom left, and now your video speed will have changed to the one you set.

Step 5: Save & Export Your Video

To finish things off, you’ll need to save your project as a video file, so you can share and upload it.

To do so, click on the red “Save Button” that’s located on the top right of FilmForth.

After you select a folder and name for your video, it will start exporting. Take into account that it might take a while for it to export, as the speed of the exporting process depends on the duration of your video.

Speeding Up and Slowing Down Using Kapwing

If you don’t want to download any apps and just want to speed up a whole video (and not a part of it), or you’re simply don’t use Windows 10, then you can use Kapwing, which is an online video editor that’s great for simple tasks like speeding up or trimming a video.

Step 1: Open Video

First, open the Kapwing online app by clicking here.

Then, click on “Upload” as shown below, and search for the video file you wish to adjust its speed.

Step 2: Speed Up or Slow Down Video Clips

Now it’s time to change the video speed, and for that, simply select the video speed you wish to use on the left menu bar.

That was easy! Wasn’t it?

Well, the downside to using this video editor, as we mentioned, is that you can’t split a video, so you can’t change video speed for certain parts of a video, only for the whole clip.

But if you have one, or various video files that you want to change the speed of, then it’s a great tool to do so.

Step 3: Export Video

Once you’ve finished adjusting the playback speed, you’ll need to export your video and convert it into actual video files. To do so, click on the red “Create” button that’s located at the bottom left.

Once you do so, your video will start processing. Like FilmForth, it might take some time to do so, depending on the length of your video. After the process is completed, you’ll be able to download your video by clicking “Download”.

The thing is, when using Kapwing you’ll need to create an account to be able to remove the watermark from your video, plus your videos will be public for everyone to see (unless you want to pay a subscription), but apart from that, it’s a good alternative if you want to change the speed of one video and don’t want to download any tools.


As you’ve seen, whether you want to change the playback speed of a certain part, or of the whole video, the process is really easy and doesn’t require any previous video editing knowledge.

In fact, I decided to write this article as most tutorials to change playback speed I’ve seen either used old tools (like Windows Movie Maker), or used video players like Media Player, which aren’t ideal tools for this job and will make the speed changing process more difficult than it should be./p>
