Video files not playing.

Hi,

We'll need to check a few things to better determine what might be the issue. We'd like to know the following:

• What is the file extension of the videos you're trying to play? To check this, right-click on a video and select
  Properties. Check what's indicated beside the File type.

• What app are you using to play the videos? You can also see this in Properties beside
  Opens with.

• Do you encounter any error messages when trying to play the videos? If so, kindly send us a screenshot.
• Did you make any recent changes in your system or was this the first it happened?

In some case, this may have to do with incorrect file association between files and apps you're using to open them. If the app beside Opens with is not the correct app for opening video files, we suggest that you click
Change in the Properties window to select the appropriate one.





In other cases, it could be that the file type isn't supported in the app you're using to play the video. If so, you may need to download the necessary codecs or updates for that particular app to play the videos properly.

Should you need further assistance, let us know right away. We'll be here.

Hi,

Thank you for writing to Microsoft Community Forums.

1. May I know, which video player you are using to play the video?
   
2. Are you able to play the video on any other computer?
   
3. Are you facing the issue with only specific video or with all the other videos?
   

This issue could also occur when the USB or SD card is corrupted when you have transferred the video.

Try the troubleshooting methods provided below to further narrow down the root cause of the issue.

Method 1: Try a different video player.

1. Try to use a different USB to transfer the video, if you are playing it on other computer or device.
   
2. I suggest you to try a different video player and check if it plays.
   
3. You can also check on different device or computer.
   

Step: Run Windows Media player troubleshooter.

1. Press Windows + R key on your keyboard together.
2. Copy and paste the below command and run each at a time and follow the onscreen instruction on the troubleshooter
