While the Photos app in Windows 10 has been out for a couple years, many people are not aware of all its features. Given the way Microsoft has added powerful features to Photos, it has the capability to offer much more to users. One such feature is the option to add the effect of slow motion in Windows 10 using the Photos app. We will explain how you can use the slow motion feature in Photos, along with an option to add the effect of slow motion online.

Part 1:How to Use Slow Motion in Windows 10

There is no need to spend hundreds of dollars on a video program if you need to perform some basic editing and effects on your videos. For instance, you can add the slow motion effect using the Photos app that comes pre-installed on Windows 10 computers.

Navigate to the folder where your video file is located and right click on it. You will go to “open with” and then choose the Photos app. When it is open in the application, you can click on “Edit & Create” and then go to “Add slo-mo”.

If you do not see the option anywhere on your Photos app, there is a chance you are running an outdated version of Windows 10 on your computer. All you need to do is navigate to Windows Update through your system menu. When all the updates install, you will have the latest Photos app with this feature.

Part 2:Customizing the Slow Motion Effect

When you are using the Photos app to add a slow motion effect to your videos, you can tweak it to your liking. You will be able to select the speed using a slider, which lets you get the precise slow motion effect that you desire.

There is also the handy option of being able to select the portion of your video where you want to add this effect. Say you are producing a longer video, where you want the effect in place for a few seconds.

Now you can select the beginning and end point using the bottom slider on the Photos app. Choose the precise starting and ending of the slow motion effect, and then watch through your video to ensure it is exactly as you want.

We recommend that you save your video file under a new name when you are done making your desired changes. It ensures that you still have the original copy of the video saved on your computer or external hard drive.

You can even create multiple versions of the file with the slow motion effect applied in different ways. Then you can watch the videos you just created to decide on the best version.
