The Velocity Render Channel is a color or grayscale image that stores velocity information about objects that have moved between the current frame and the next frame. 


## **Overview**

---


## **Parameters**

---


## **Common Uses**

---

The Velocity Render Element is useful for adding motion blur in post production at a composite level, without the need for rendering. See the render before and after compositing.



## **Notes**

---

- It is recommended to disable this render channel when rendering with Motion Blur. This channel is generated when 3D motion blur is enabled in V-Ray. However, the pass will also be motion blurred along with the rest of the image. This will make the element not usable in compositing.
