What is an MJ file?

MJ files mostly belong to MediaJoy. MJ files are video files that use the Motion JPEG format. They store video by encoding each frame as an individual JPEG image, making the video a sequence of still images played quickly in order.

This file type is common in MediaJoy applications for simple video playback.

A variant of MJ files is produced by VideoJet software and is sometimes used as a backup file in systems like DJI FlightHub.

FilExt.com note: Playing these files typically requires a media player that supports Motion JPEG, such as VLC or QuickTime. For files associated with DJI FlightHub, using the original DJI software can ensure proper access to embedded flight data.

How can I open an MJ file?

You need a suitable software like MediaJoy to open an MJ file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your MJ file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a MJ file directly in the browser:. Just drag the file onto this browser window and drop it.
