You can modify the motion blur applied to the render camera(s) in your composition. This gives the appearance of movement in the scene relative to the camera—see Adding Motion Blur and Depth of Field to a Scene.

To modify the motion blur:

1. Select the Cameras tab.
2. From the Cameras list, select the render camera(s).
3. Under Motion Blur, modify the Time Dilation. A higher value increases the blur effect giving the impression of faster motion, and vice versa.
