Hello,
Welcome to the Microsoft Windows Community.
Good afternoon. Which edition of Windows are you using? To begin with:
- Check the Recycle Bin; if you find the file, you can click "Restore." If the Recycle Bin is empty, follow the step below;
- If you have OneDrive installed, open it and check if you can find the file in the recycle bin; if so, click "restore."
- Press Win+R, paste the command rstrui, and press Enter. Select a restore point with a date prior to the deletion of the video, then click "Next."
Good luck, and please let us know the result.
