Mostly used for VirtualProduction
, this camera simulate the optical distorsion of a real one.
The physical camera cannot be used as a inherited camera due to the optical distortion it applies to the rendering.
By default, the physical camera is setted in

Model and Resolution
The Model parameters defines the type of camera you simulate and how the radial distorsion will be calculated.
a Tracker represent a real tracker and is part of a Tracking System
used to place this camera also sends optical information (focus, zoom, etc), those datas can be applied directly as the physical camera model using the "use tracker model" option.
Pick a model in the type list to access to its parameters. The types refers directly to the following
Use any external controller in MIDI or OSC, DMX and ArtNet

Change the resolution of the camera:
If you want to change the resolution of the physical camera, you need to select in the first

Mixing 2D and 3D
Mixing 2D and 3D content on the same level when using a physical camera is not recommended as it induces radial distortion on the 2d element
The recommended workflow is to preCompose your 3D element like this:
Save and Load your the camera Model
To export your camera Model you can right click on the model and save it
This will create a
A file that contain Model for a Physical Camera
to import it you can right click on the model and load it
or drag and drop it onto a physical camera in your tree.
