At the top of the **Camera Calibration** panel, the buttons enable you to load, save or clear camera calibrations in your Tracker system.

As noted in [Calibrating Vicon cameras](https://vicon-help.atlassian.net/wiki/spaces/Tracker40/pages/14191823), the camera calibration files that are saved after a completed calibration are not permanent and can be overwritten. If you want to keep a calibration so that it is not removed from this folder, you must save it.

If you want to extract the .*xcp* from a motion capture file (.*mcp*), such as one from a captured review, you must load that review and save it.

Loading and saving calibrations can be useful for:

- Comparing calibration changes
- Streaming data through Vicon Virtual System (see the [Vicon Virtual System User Guide](https://vicon-help.atlassian.net/wiki/spaces/VVS/pages/15630740))
