Vector blur is a great way to add realism to your animation. Your eye naturally sees moving objects moving as a blur, because that is how your brain processes the motion. Without some sort of blurring, animated moving objects don't look as if they are realistically moving. Blender's animations are by default rendered as a sequence of perfectly still images. This is unrealistic, since fast moving objects do appear to be 'moving', that is, blurred by their own motion, both in a movie frame and in a photograph from a 'real world camera'.

To obtain such a blurring effect with moving objects, Blender can be made to render the current frame and some more frames, in between the real frames, and merge them all together to obtain an image where fast moving details are 'blurred'. The goal of this tutorial is to demonstrate how to blur moving objects in Blender.

Hi Tiago...Glad to have helped. I hope to see you at my Blender 3D form where there are many other people who can help you.

To get the Speed socket, go to the Scenes panel (F10), then click the Render Layers tab. Make sure that the Vec (Vector) button is clicked on before you go to the Node Editor. This should give you the Speed socket in the Render Layer node.

Some interesting gotchas with vector blur: * if an object is vector blurred, its shadow is not! * if a vector blurred object is moving behind a (ZTransp or RayTransp) glass, it won't appear blurred through the glass * if a vector blurred object is moving in front of a (EnvMap or RayMir) mirror, it won't appear blurred in the reflection
