This node is used to read colour and depth data from a Kinect Or RealSense camera. This node carries both colour and depth information. Post Effect nodes and Video Processing nodes attached to this node will operate on the colour data only, unless specifically designed to read the depth data – such as the Depth Camera / Kinect Colour Key node. The RGB channel is read from the camera directly, or set to white if the camera does not provide colour data. The alpha channel is set to a mask value based on the depth, using the near and far clip plane parameters. If “Output Depth” is selected the depth data is output in the colour channel as luminance values.
Where multiple Kinect cameras are connected they may be selected via the “Kinect Camera Index” parameter. A pre-recorded stream may be used instead of live Kinect camera data by setting its resource via the Kinect Stream parameter.
Multiple Nodes can be used for streaming both Kinect 2 and Kinect 4 sources together on the same PC.
For the output node to work, the correct sensor type has to be selected and enabled within Devices/VideoIn/Kinect settings.
When Kinect 4 Sensor Type is selected, additional options are enabled: Depth Sensor Mode and Colour Sensor Mode as Kinect 4 supports a number of range/FOV and colour sensor resolutions. Typically Near/narrow range/FOV depth modes have lower noise characteristics and therefore higher quality than Far/Wide range/FOV depth modes.
Colour modes supported on Kinect 4 can go up to 3072p 4k resolution but the higher the resolution the higher real-time cost. We recommend 1080p colour resolution for real-time.

|Near Clip Plane||The closest distance that will be rendered. NB: Reducing this value too low can reduce the accuracy of aspects of the render.|
|Far Clip Plane||The furthest distance that will be rendered by this camera. NB: Increasing this value too high, without increasing the Near Clip, can reduce the accuracy of aspects of the render.|
|Depth Clip Hardness||How harsh the falloff is for depth data.|
|Edge Fade Width||Refinement width for depth edge mask|
|Kinect Depth Scale||Scaling of the Kinect Z depth|
|Colour Image Offset X/Y||Manual alignment of the colour image to align with depth.|
|Output Depth||Toggle whether only the depth image is output.|
|Camera Type||Choose the camera type: Kinect 1, Kinect 2, Kinect 4, Realsense, Realsense 2 or First Detected to choose the first sensor Notch detects (has specific sensor type ordering)|
