Part 1. QuickTime Won't Play An MOV File - Possible Reasons

As Apple's proprietary media player, QuickTime is distributed in free basic versions for Mac and Windows systems. Apple developed MOV as a digital video format that works natively with QuickTime. Although an MOV file may be compatible with QuickTime, it may still fail to load in the QuickTime player for the following various reasons:

Software Update

If QuickTime fails to play your MOV file, then it is possible that your application is obsolete and no longer supported. The media player may not be able to read the digital video because the technology that was used to encode it was recently developed. When in that condition, make sure to update your QuickTime player to the newest version.

Media Encoding

If your MOV file fails to load in other media players besides QuickTime (e.g. iTunes, VLC, GOM Player, Zoom Player), then the asset is probably corrupt. Since the digital video was not properly encoded in the first place, it cannot be read by QuickTime ( or any other supported application) even it is a compatible format.

Filename Accuracy

A file extension reveals what type of data is contained in a file, it also indicates which type of software should open the file. But since file extensions can be easily edited, they may not always be accurately assigned to files. As a result, your MOV file may not load in QuickTime because it has been misidentified as a digital video that is compatible with the application. But free tools like MediaInfo and FileAlyzer can analyze a problematic file's properties and confirm if it is using the right file extension.

Digital videos like MOV files are all products of compression. During compression, multiple streams of audio and video tracks are written with a special algorithm called a codec. If your MOV file fails to load in QuickTime, then it is possible that your system is not equipped to read the digital video's codecs.
