The Motion Blur section of the Properties Inspector has two settings:
Samples: Use this slider to set the number of subframes rendered per frame, where
1 frame represents 360 degrees. Higher Samples values result in a higher-quality
motion-blur effect, but are more processor-intensive. The default Samples value is 8. The
maximum possible value is 256.
Shutter Angle: Use this slider to define the size of the motion blur that appears for
animated objects. Increasing the shutter angle increases the number of frames over which
the shutter is open.
The following image shows a shape keyframed to move quickly across the Canvas
horizontally.
In the next image, Motion Blur is enabled and Samples is set to the default value of 8.
Note: When using larger Shutter Angle values, it may be necessary to increase the Samples
value to eliminate unwanted artifacts.
In the above image, the Shutter Angle is set to the default of 360 degrees, which represents
1 frame. In the following image, Shutter Angle is set to 600 degrees.
