After loading a motion from a CMZ file, the mocap model can be controlled using the playback widget located under the 3D view.

You can drag the slider to play back some of the frames, or use the buttons on the right to control the animation:

<| : Move to previous frame

 : Play

|| : Pause

>| : Move to last frame When Repeat is selected, the playback will be continuous, i.e., after the last frame, the play back continues with the first frame. The Playback Speed controls the speed of the play back relative to real-time.
