.mtb file is On Body Recording (OBR) file. It will be saved in your Body Pack when you start or stop recording in OBR mode.

You need to import .mtb file and convert .mtb into .mvn files by using our MVN software.

.MVN

.MVNS

.mvns file contains the session data (e.g. multiperson mocap data, object data, reference video files).

This is a text file that includes the name of specific .mvn, .mvno files and/or video files. Once open .mvns, all recordings in .mvns files are opened in the same 3D viewport in MVN and edited at the same time.

The picture below shows the common format of .mvns file. You can edit it simply by using notepad.

Moreover, you can create your own simplified .mvns file. Just input the filename of multiple .mvn files (and .mvno if you have) in notepad. Then save it as .mvns. Please see below example.

Files included in the .mvns file should be saved in the same path.
