Possible Causes for Unsupported Video Format Error

To serve various playback purposes, dozens of video formats have come into existence. However, not all media player has full support for all these video formats. On many occasions, you would see an error message pop up on your Windows player saying this media format is not supported and not playable, such as the 0xc00d36c4 error and the 0xc00d5212 error.

The most likely cause for this type of problem is that the media player is missing the relevant codec for the video or the video container format is not compatible with the player. If the error persists on other video players instead of on one specific player, chances are that the video file itself is corrupted and hence cannot be played.

Fortunately, there are many solutions to this kind of error. The next part will share the best four working ways to fix unsupported video format errors on Windows. Let’s get into the details.

Note: If your video is DRM-protected, it cannot be played on any random player except the player made by the company that has produced the video. Removing the protection could infringe the copyright law, so we won't discuss this situation here.

How to Fix Unsupported Video Format?

1. Install Windows Codec Pack

Since the primary reason for the unsupported video format error on Windows is the missing codec, the best way to fix it is to install additional codecs to work with this file. You can get most of the common codecs from a codec pack called L-Lite Codec Pack. The standard version is enough for average users. And after you’ve downloaded the codec pack, follow the installation prompts to finish the preferences setup.

It is worth noting that, however, K-Lite Codec Pack is best compatible with Windows Media Player. If you are using VLC Media Player or the default Windows Movies & TV app, you can’t use this pack directly.

2. Convert Unsupported Format

If you do not wish to change the codec environment on your Windows, you can try to use a reliable video converter to convert video to a Windows-supported format for easy playback. Here I’d like to recommend WonderFox HD Video Converter Factory Pro, a very safe and useful converter that can easily fix the audio and video format/codec not supported issues in simple steps. A brief tutorial is given below.

  1. Download and install this converter
  2. Run the software and open the Converter.
  3. Drag the unsupported video(s) into the program.
  4. Click the format image and select an output format, such as MP4, WMV, AVI, etc.
  5. Click Run to start the conversion.

3. Try a Different Media Player

If you can’t play a video on a certain video player, the simplest way to solve this problem is to try a different media player. There are a bunch of good video players for Windows out there. For example, VLC, GOM player, KM player, and PotPlayer can run all major key formats hassle-free.

Yet, as I’ve mentioned earlier, a media player that can play any video format is hard to find. It is still possible that you meet another unsupported video format error again. And then you have to either install additional codecs or convert unsupported video for smooth playback on your device.

4. Repair the Corrupted File

There is a chance that your video file could be corrupted, especially when you have tried to play it on several different players and devices to no avail. For this kind of issue, it’s better for you to use a video repair tool like Stellar Repair for Video.
