How Do I Fix Video Format not Supported on Windows

My Windows 10 is not letting me play videos, and whenever I try to play a video, a notification pops up stating: "Cannot playback the file. The format is not supported (Error=80040265)."

These days, numerous video formats are available for user convenience. Several file formats are supported by various software, while others are not. If you are facing an error that reads as video format not supported, it can prove to be a severe cause of annoyance.

So, how to fix file format not supported? Before you are the ultimate guide to knowing what causes the issue to arise in the first place and what can be done in order to get rid of it once and for all, without further ado, let's get started!

Part 1: What Causes the "Unsupported Video Format" Error?

Certain instances occur when your Windows displays a notification that says your video file cannot be played. The error can prove a real nuisance at times. It is essential to learn the reasons behind the issue before learning to eliminate it.

The video format, not supported problem can arise due to multiple reasons. As the name suggests, the issue primarily stems from the file format not supported by the respective media player. A few other potential causes are listed below.

  • Missing Codecs

The main reason that makes a video format unsupported is a lack of proper codecs. Codecs are parts of files that contain adequate information to encode or decode data. In other words, codecs are the main driving force behind a file. If your file is missing proper codecs, it will not be played on your device.

  • Damaged or Corrupt Files

If you cannot play the video on your Windows, the file itself may be facing problems. If the video format is damaged or corrupt, it will not be played. Even when the file is not completely downloaded or transferred or is susceptible to virus and malware, Windows is unable to play your file.

  • Incompatible File Format

Another reason for the "video format is not supported issue" to arise is that the file format you are trying to play is not compatible with the respective media player. In such cases, the media file likely uses a codec that the media player does not support. Hence, the file does not play.
