"All the files I try to play all fail with the message 'Cannot render the file'. They are dozens of files and they all have the same bug."

Media Player Classic - Home Cinema (MPC-HC) is a pretty nice media player. Though it doesn't support a wide range of video formats/MIME types like bigger media players (such as VLC) do, it does support a variety of media formats. "Media Player Classic Cannot render file" error is thrown when Media Player Classic encounters a video format it doesn't recognize or one it cannot play/handle. While this error may be from the MPC-HC software itself, it could also be that your video file is corrupt. If the cause of the error is from MPC, it might have been from a tiny misconfiguration or improper installation –which can be easily fixed from within the software. However, the fault can also lie with/in the video file itself.

In the article, you'll learn the various cause of this error; the way forward for fixing the error, and alternatives to Media Player Classic too of course!

Part 1. Possible Causes of Cannot Render The AVI/MP4/MKV File in Media Player Classic or Other Players

Here are the major reasons why Media Player Classic and other players wouldn't open your media file;

1. Wrong Configuration

This is usually the case with Media Player Classic. Every video player comes with certain files they must access before playing your media files. This includes, but is not limited to codec files. Depending on the way the media player in question stored these files on your device, they may no longer be able to access such files which will lead to errors. The inability of your media player to access configuration files may be as a result of you knowingly or unknowingly tempering.

Fix? Yes. Usually resetting the configuration of the media player could be the fix you've been looking for or uninstalling and reinstalling.

2. Improper Installation

Most media players, for example, on the Windows Operating System, come with an installer. Software applications implement this measure to prevent future difficulties that could be faced by their esteemed users/customers. During installation, various configurations are made and paths set. If the software misses this, then you're bound to run into issues.

Fix? Yes. You should try uninstalling and reinstalling the media player. Maybe the software will get it right on your next installation.

3. Unavailable Video Codec

Although MPC-HC does not officially support third-party codec files, this is one of the top causes of video errors —not just with MPC but with the majority of other media players.

Fix? Yes. While you can automatically update codec files on some media players via the menu -> settings, some don't come with that option, so you'll have to manually install codec files.

4. Corrupt Media Files

When you encounter this error, at first, it is almost not obvious that your media file is corrupt. Especially if you discover that other media files play the same 'corrupt' file. But file corruption is the top cause of media player errors.

Fix? Yes. You can simply use a dedicated video repair tool (like the one mentioned below) to easily fix almost every possible video file error while sparing yourself the troubles.

5. Virus Infection

Of all the causes of media player error, virus infections are the most misunderstood and annoying of all! Sometimes you'll remember playing the same file with the same player some time ago but suddenly your play throws a "Cannot Render The File error". If that's your case then its almost definitely a virus at work!

Fix? Um... Yes. This one is kind of tricky as some malware/virus could be a real pain in the butt. So, apart from using good antivirus software to scan your device, you should also consider updating your operating system's software. Make this a habit.
