Video Sampler Modifier

Video Sampler Modifier

Samples a video to generates a modifier value.


Method #

This node outputs a modifier value based on the RGBA values of pixels from a video input. You can either sample a single spot, or sample an area with the Sample Rectangular Area Parameter.

The output is a numeric value that can be further processed with other modifiers, or directly connected to a parameter in another node, using the operation method selected.


These properties control the core behaviours of the node.

Sample Location UPoint along the U axis that is sampled.
Sample Location VPoint along the V axis that is sampled.
SmoothingAdjust the amount of smoothing to applied to the output value.
ScaleAdjust the scale/range of the modifier.
OperationThe 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 ModeHow 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 PixelsThe sample location describes the location in pixels, not a percentage along width and length.
