What is an MTN file?

MTN files mostly belong to Live2D Cubism Editor. MTN files are used in Live2D animation systems. They contain motion data that tells 2D models how to move, change expressions, and perform actions.
These files store keyframe and parameter information that the Live2D software reads to animate characters.

They are part of a suite of files used by Live2D Cubism products.

They work with complementary file formats that define models and physics.

They are not traditional video files but data files specific to motion control.

Live2D Cubism Editor
A *.MTN file is a data file primarily associated with Live2D Cubism software. It stores animation motion data used for creating dynamic and expressive 2D character animations. These files contain information about the various movements, deformations, and transformations applied to a 2D model over time. The data within the *.MTN file defines how different parts of a 2D character model should move and deform to create the desired animation. This data is used by Live2D Cubism to render and display the animation in real-time. The *.MTN format is specific to Live2D Cubism and is used for storing and exchanging animation data within the Live2D ecosystem. This file format is classified as 2D Animation Data.
