Method

This node outputs a value based the luminescence values of specific pixels from a video input.

Example Nodegraph

Attributes

Name Description
Sample Location U Point along the U axis that is sampled.
Sample Location V Point along the V axis that is sampled.
Smoothing The amount of smoothing to applied to the output value.
Scale The scale/range of the modifier
Operation The operation to be performed on the targeted parameter.
  • Add, adds to the parameter value.
  • Subtract, subtracts from the parameter value.
  • Multiply, multiplies the parameter value.
  • Replace, replaces the parameter value.
Latency Mode How the video is sampled with respect to performance.
  • Performance, The video is sampled with some latency, to avoid stalling the GPU and giving higher performance.
  • Low Latency (Slower), The video value is sampled immediately, stalling the GPU but giving the lowest possible latency.
Location In Pixels The sample location describes the location in pixels, not a percentage along width and length.

Inputs

Name Description Typical Node Input
Video Node The video node from which values will be generated. Video Loader

Outputs

The output is a numeric value that acts upon a connected parameter input of another node, using the operation method selected.
