  1. Open your video project in the Photos app.

  2. Select Add > From this PC.

  3. Browse to the files and select them.

If that didn’t work, follow Option 1 (get the extensions for the Photos app) or try Option 3 for your photo files.

Option 3 (photos only): Use OneDrive to automatically convert your photo files

To make sure it worked, add your files to your video project by selecting Add > From this PC and browsing to the files.

Instructions for watching videos in unsupported formats on Windows

Using third-party video playback software

Movies & TV app only supports some popular formats like MOV, AVI and MP4. Windows Media Player supports several other file types, but Microsoft seems to be pushing users away from the pre-installed app.

Since the Movies & TV app doesn’t support all video file formats and Windows Media Player hasn’t been updated in a decade, the best way to play unsupported video files on Windows 10 is to use the software. play third-party videos.

VLC Media Player

VLC Media Player is one of the best options for Windows 10 users. VLC can play most audio and video file formats, making it a powerful alternative to the default player.

You can play video files, live stream, or play DVDs with VLC if the default Movies & TV app doesn’t do this. It also comes with hundreds of other options for customization. To open a video file in VLC, click Media > Open File from the top menu.

MPV is a powerful alternative video player for Windows users. It’s cross-platform, so it’s also a choice for Linux, macOS, and Android users.

Unlike the endless and customizable menu that VLC offers, MPV is simple and straightforward, with no menus and only basic playback options available. This is portable software so you don’t need to install it, just run it from USB flash.

To open a video in MPV, simply drag the file into the open MPV interface.


PotPlayer is one of the best video player software for power users. It offers plenty of customization, supports hardware acceleration for high-resolution videos, and includes a built-in video editor to edit video files while playing.

The default interface is black but you can customize it with the built-in theme and colors.

To open a video file in PotPlayer, right-click inside the open PotPlayer interface or click the PotPlayer button on the left. From here, click Open File(s) to select the video file.

Change default video player

If you want to use third-party video player software as your default video player, you can do this in Windows 10 settings.

You can access the Settings menu by right-clicking the Start menu on the Taskbar and clicking the  Settings button . From here, select  Apps > Default Apps.

In the Default menu, click on an existing video player. If installed, the Movies & TV application will be the default software.

Select a third-party video player from the drop-down list. From now on, Windows will open every video file it detects with the video software you selected.

Install additional video codecs

Codec is a type of software that decodes video files into appropriate audio and images. If the PC lacks a codec that matches the video file format, the video will not load. You can download and install third-party video codecs on your computer.

However, you should be careful, do not download from less reputable websites because this can expose your computer to malicious ads.

To avoid this, download the K-Lite Codec Pack, one of the most popular video codec packs. It adds support for a significant number of media file formats, including FLV and WebM.

Installing K-Lite will add video format support to Windows Media Player and some third-party video playback software. However, this method does not work with the default Movies & TV app.

To get started, download the K-Lite Codec Pack of your choice from the link below and run the installer. It will default to the Normal setting with presets. If you want to customize this, select  Advanced.

Click Next to continue the installation process.

You need to select your favorite video player as the default option of K-Lite. If you use the Movies & TV app as a video player option, you’ll get an error message like this:

If you use VLC, you will also get the same warning. VLC contains its own set of video codecs, so it is not necessary to download other codecs.

Instead, choose Media Player Classic, the older Windows Media Player, or another third-party video player.

Confirm other settings and then click  Next  to continue.

 The next installation steps will appear if the Install MPC-HC as a Secondary Player option is selected  in the previous screen.

Confirm the settings for the K-Lites Media Player Classic and then click  Next  to continue.

Confirm the next stage of K-Lite Media Player Classic installation. Here, the installation is already set up, so click  Next  to continue unless you want to change the hardware acceleration option for K-Lite Media Player Classic.

Set the language for subtitles and captions on the next screen. Select primary, second, and third language from the drop-down menu.

When done, click Next.

Select your preferred sound profile on the next menu. This is also a preset, so if you want you can use the default settings and click  Next  to continue.

If asked, decline any option to install additional software at the next stage by clicking the  Decline button.

Finally, check once again the K-Lite installation option and then click on the  Install button  to start the installation. 

When the installation is complete, click on the  Finish button .

The video player of your choice can now play some additional video formats.

Convert to another video format

If you’ve set up using Movies & TV, you only have one option to convert the unsupported video file to a format that the default Windows player can open.

There are many ways to do this. The live site will automatically convert the video file to another format. For example, searching for FLV to AVI converter will give you a list of online conversion sites but this can be risky and not recommended.

The best option, especially for users who have VLC installed, is to convert files using this software.
