FreeD is an industry-standard protocol used by cameras to directly send tracking data — such as transform, rotation, focus, and zoom — to virtual production systems. It allows production systems to incorporate realistic virtual studio sets into video productions without the need for additional hardware.

Here's how to enable FreeD on Mars and add Mars to Aximmetry:

  1. On the Mars dashboard, tap Settings and check your firmware version. Make sure you have Mars firmware 2.03.999.1 or later installed.

    For details on how to update the firmware, see Manually updating the Mars firmware.

  2. On the Mars dashboard, tap Network (or tap the Mars IP when the network is active), and then tap Camera tracking protocols.
