I used to download a lot of mp4's from untrusted sources. But I discovered that they could contain malware. I would like to know if there are any methods to clean or to check video files for malware.

MP4 files are not executable files. This means that they are unable to execute malicious code directly. That being said, it is possible for the program that decodes/plays the file to have a vulnerability that the mp4 file could exploit. The threat that a video file poses to your system is much less than the threat a downloaded program poses to your system.
Your best bet for avoiding malicious mp4 files is using up to date software when decoding/playing these files. You can also use a throwaway virtual machine to view these files. Antivirus software would also most likely help prevent infection through this method.
