A MOTN file is a project file created by Apple Motion, a specialized motion graphics and compositing application designed for macOS. This file format serves as a container for 2D and 3D visual effects, titles, transitions, and complex animations used in video post-production. Unlike a rendered video file, a MOTN file is an XML-based document that stores instructions, keyframe data, behavior settings, and references to external media assets such as video clips, images, and audio files rather than the media itself. One of the most significant features of the MOTN format is its deep integration with Final Cut Pro; users can save Motion projects as templates, which then appear directly within Final Cut Pro for easy customization of text and parameters. Because it is a project-based format, it allows for non-destructive editing, meaning creators can reopen the file at any time to adjust layers, filters, or timing without losing quality. It is a proprietary format exclusive to the Apple ecosystem and is essential for professional editors working on high-end motion design and broadcast graphics.
