Transmit Tunnels in Camera Compounds

Transmit Tunnels in Camera Compounds

Transmit Tunnels in Aximmetry allow camera compounds to send data anywhere within your Flow Editor logic without the need to connect pins directly to the camera compound. This enables you to access information from deep within the camera compound without needing to open and modify it.

Transmit Modules register data with a named "tunnel" (Into Tunnel pin). Other Transmit modules can access the same data by selecting the tunnel name (From Tunnel pin).

NOTE: Tunnels that start with the word CAMERA are usually used within Render_General compounds. In the case of LED wall productions, the CAMERA tunnels transmit values for AR Overlay rendering for the Render_General compounds.
NOTE: Tunnels that start with the ELEMENT - prefix are meant for internal use within the camera compound. It is unlikely you will ever need to use such a tunnel.
NOTE: These tunnels can help you create Linked Compounds that do not require direct connections to the camera compound, enabling easy use across different projects.

List of Camera Compound Tunnels

Logical

• EDITING MODE: Indicates if the Camera Path Points are being used in green screen production cameras.
• FREE MODE: Indicates if Free Camera Mode is active; available in every type of camera compound.
• LENS_DISTORTION: Active if the SCENE panel's Lens Distortion parameter is enabled in tracked cameras.
• CAMERA CUT: Activates when switching between cameras or camera paths, if the new camera or path is not very close to the previous one. The LED Wall camera compounds include a CAMERA CUT AR Tunnel, which is timed according to the camera’s Picture Delay. NOTE: If you want to detect camera or path changes regardless of distance, use the SELECTED CAMERA tunnel, the CAMERA PATH tunnel, or a combination of both.

Scalar

• ANIMATION DELAY: Animation Delay value; used only in LED Wall workflows.
• CAMERA APERTURE: The current aperture value used by the Selected Camera. It can originate from tracking data or, for example, be set per Camera Paths.
  
• CAMERA ASPECT: Represents the camera aspect ratio of the Selected Camera. Present in camera compounds with camera tracking, as these cameras have the aspect ratio defined by the tracking data or calibration file.
• CAMERA FOCUS: Current focus value of the Selected Camera.
• CAMERA FRAME ASPECT: Only available in Aximmetry-rendered scenes. Use this to retrieve the pixel aspect ratio of rendered frames of the Selected Camera.
• CAMERA GUARD BAND: Only in Aximmetry-rendered scenes with camera tracking, corresponds to the Edge Expand. Use this for viewport compensation by connecting a module’s input pin of the same name (for example, the Camera module’s Guard Band pin).
  NOTE: In Unreal-based compounds and LED Wall compounds, the CAMERA OUT SIZE vector tunnel’s size is already expanded by the edge expand setting.
• CAMERA ZOOM FACTOR: Current zoom factor of the Selected Camera.
  

Integer

• CAMERA PATH: The camera's selected Camera Path, used in green screen production cameras. Each path uses a subtunnel: CAM 1 uses subtunnel 1, CAM 2 uses subtunnel 2, etc.
• SELECTED CAMERA: The index of the Select Camera.
• VISIBILITY GROUP: Aximmetry-rendered scenes only. Defines billboard-specific visibility groups to control the visibility of green camera billboards.

Vector

• CAMERA CUSTOM SENSORS: Custom sensor data from the Selected Camera of the tracked camera compounds.
• CAMERA OUT SIZE: The rendered size of the Selected Camera. In tracked cameras, this is the same as the input video's resolution. In virtual cameras, it is the same as the Rendering Frame Size. In Unreal camera compounds, it is increased by the Edge Expand parameter.
• CAMERA SENSOR SIZE: Sensor size for the currently selected tracked camera. You can Override the Sensor Size (Width) in the INPUT panel.
• LEDWALL DESC: Used only in LED Wall workflows. Contains transformation, size, radius, and resolution data for each LED wall panel. Uses subtunnel per LED Wall panel: LED Wall 1 uses subtunnel 1, LED Wall 2 uses subtunnel 2, etc.
• LENS DISTORTION: Lens distortion coefficients of the Selected Camera.
• TONE MAP PARAMETERS: Used in Aximmetry-rendered green cameras with billboards to share tone mapping parameters with the Render compound from the billboard’s inverse tone mapping.

Transformation

• CAMERA TRANSFORMATION: Full position, rotation, and scale of the Selected Camera.
• INPUTS BILLBOARD POSITION: The 3D position for each billboard. The position includes offsets from the Lift, Look At Camera, Lock To Camera, and Auto Position parameters on the Billboard panel. Uses a subtunnel per input: INPUT 1 uses subtunnel 1, INPUT 2 uses subtunnel 2, etc.
  
• INPUTS BILLBOARD POSITION BASE: The 3D position for each billboard. Same as the Transformation parameter on the Billboard panel. Uses a subtunnel per input: INPUT 1 uses subtunnel 1, INPUT 2 uses subtunnel 2, etc.
• SCENE BASE CAM TRANSF: Base Cam Transformation of the SCENE panel; available only in compounds with camera tracking.
• STUDIO BASE CAM TRANSFORM: Base Cam Transform parameter from the Studio panel in tracked green camera compounds.
• STUDIO CAMERA TRANSFORMATION: Studio panel's Camera position in tracked green camera and LED Wall compounds. This can be useful when adding Studio Models or Digital Extension Aux Masks.
• STUDIO GLOBAL TRANSFORM:  Studio panel's Global Transform parameter in LED Wall compounds. This is useful when adding Digital Extension Aux Masks or positioning models according to the Global Transform or LED Walls position.

Text

• INPUT TECH DATA: Technical input metadata, used internally in the camera compound for the ON SCREEN panel's SDI information.

Video

• INPUTS INPUT: Raw video from each input. Uses subtunnel per INPUT: INPUT 1 uses subtunnel 1, INPUT 2 uses subtunnel 2, etc.
• INPUTS CROPPED: Video after cropping. Uses subtunnel per INPUT: INPUT 1 uses subtunnel 1, INPUT 2 uses subtunnel 2, etc.
• INPUTS KEYED: Video after cropping and keying. Uses subtunnel per INPUT: INPUT 1 uses subtunnel 1, INPUT 2 uses subtunnel 2, etc.
  
• INPUTS STUDIO: Video after both keying and studio mask are applied. Uses subtunnel per INPUT: INPUT 1 uses subtunnel 1, INPUT 2 uses subtunnel 2, etc.
• INPUTS STUDIO GREEN MASK:  The mask of the green area in the red channel of the video. Uses subtunnel per INPUT: INPUT 1 uses subtunnel 1, INPUT 2 uses subtunnel 2, etc.
  
• ELEMENT - AR_BACKGROUND: Used internally in TrackedCam+AR_Unreal compounds.
• ELEMENT - AR_COMBINED: Used internally in TrackedCam+AR_Unreal compounds.
• SIMULATED CAMERA VIEW: The rendered Frustum of the LED Wall camera compound after applying lens distortion, cropping, and any Digital Extension adjustments, such as LUT.
• MIRROR-1: Aximmetry rendered scenes only, used by Render compounds ([Common_Studio]:Compounds\Render) to provide a mirrored camera image for reflective objects (see Planar Reflections).
