Video Sampler Modifier
Updated: 4 Dec 2023
Samples a video to generates a modifier value.
Video Sampler Modifier
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.
Parameters
These properties control the core behaviours of the node.
Parameter Details Sample Location U Point along the U axis that is sampled.
Sample Location V Point along the V axis that is sampled.
Smoothing Adjust the amount of smoothing to applied to the output value.
Scale Adjust 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.
