Video Processing

Method #

Video processing nodes control video post-fx in the scene.

Depth Processing

Depth Processing nodes generate and change depth data using various techniques.

Luminance From Depth Generates a greyscale luminance image from a depth source, usually a Depth Camera / Kinect Source

Feature Tracking

Feature tracking nodes detect and track features in an image.

Blob Tracker This node generate blobs from an input image, and outputs transformation information for each of those blobs.
Face Tracker Searches the supplied image or video for faces.
NVIDIA AR Body Tracker Utilise the NVIDIA Broadcast SDK on RTX GPUs to generate rigged skeleton poses based on 2D video.

Image Processing

These nodes analyse and modify the image with different effects.

AI Upscale Upscales the resolution based on the machine learning algorithm.
Composite Sources Composite two image sources to one image.
Downsample Downsample the resolution of the input image.
Frame Buffer Buffers a frame for a period of time.
Frame Delay Frame Delays the image played by a specified frame amount.
Generate Normal Map Generates a normal map based off the luminance values from an image.
Resize Resizes an image to specified size.
Upsample Upscale the resolution of the image.

Input Output

These nodes control where video is imported from, and where video is output to.

Colour and Depth Source Combines two input images and generates a depth camera source from them.
Depth Camera / Kinect Source Read colour and depth data from a Kinect or RealSense camera.
GBuffer To Image Allows GBuffer channels from a rendered scene to be used as video nodes for compositing or export purposes.
Image File Loader Loads an image from disk based on a specified filename.
Image Tile File Loader Loads a series of images from disk and composes them as tiles inside a single large texture.
Multiplex Sources Takes multiple video inputs and outputs a single video based on the Source Index attribute.
Rendered Video Source Output the rendered image from a Render Layer node for other nodes to use.
Video Clip An alternative source for an imported video or image source from the resources window.
Video In Source Use input from a video capture device (DirectShow / Media Foundation).
Video Loader Source for a video or image from a file or from a media server (when running as a block).
Video NDI Source Use input from an NDI IP video stream.

Motion Processing

Optical Flow Analyses an image and visualise the movement of objects in the scene.
Temporal Filter Combines multiple frames together and filters out overlapping values.


Video Null Creates a copy of the upstream video node.
