The Model parameters defines the type of camera you simulate and how the radial distorsion will be calculated.
If the Trackera Tracker represent a real tracker and is part of a Tracking SystemRead More 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 Control DeviceUse any external controller in MIDI or OSC, DMX and ArtNetRead More tracking protocols (except for pinhole):
Change the resolution of the camera:
If you want to change the resolution of the physical camera, you need to select in the first Stage ElementAn element inside the StageRead More group. That can be a Stage Elements GroupGroup multiple stage elements togetherRead More or the Stage3D modeling of the real-world video setupRead More itself. Then in
Default Camera Resolution
to the wated value.
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 CameraModel .opticA file that contain Model for a Physical CameraRead More file
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.
