Smooths noisy motion-vector or auxiliary vector data before temporal interpolation, motion blur and other vector-driven effects.
Overview
What VectorDenoise does
Smooths noisy motion-vector or auxiliary vector data before temporal interpolation, motion blur and other vector-driven effects.
VectorDenoise cleans motion/vector data rather than visible film grain. Average smooths unstable vectors and Threshold decides which changes are treated as noise, so aggressive values can remove real local motion as easily as they remove jitter.
Place it immediately before tools that consume the vectors—interpolation, vector motion blur or other temporal effects—and use the Layers options when vectors live in auxiliary passes. The goal is stable direction data, not the smoothest possible vector field.
Mental model
Imagine a motion-vector pass as a field of arrows. VectorDenoise removes small random disagreements so neighboring arrows represent coherent motion instead of jitter.

Important parameters
Start with these controls before reaching for more complicated workarounds.
Threshold
Defines which vector differences are treated as noise instead of real motion.
Use Layers for Input Vectors
Reads vector data from image layers/AOV structure when vectors are not stored in the default channels.
Practical setup
A reliable workflow
- 1
Connect the image or multilayer source containing vector data.
- 2
Enable layer input if the vectors live in AOV layers.
- 3
Increase Average only until small jitter is reduced.
- 4
Set Threshold so fine real motion is preserved.
- 5
Feed the cleaned vectors into the temporal or motion effect.

Using VectorDenoise as ordinary image noise reduction
Over-averaging and erasing small motion
Setting Threshold so high that real vectors are suppressed
Cleaning vectors after the effect has already used the noisy data
Production notes
Practical tips
Judge vector cleanup in motion, not just on a still frame.
A slightly noisy but accurate vector field is often better than an over-smoothed one.
