Effect Overview

Applying this effect on a per-object basis will enable motion blur on moving objects. The Motion Blur effect can be found under the Stylize tab in the Effects Browser.

PREREQUISITES: Effect must be applied to the object that is in motion, not the scene.

  1. Movement: [ Default 50 ] [ Range 0 - 100 ] Determines the length of the motion blur. 0 being no blur and 100 being a long blur

  2. Jitter: [ Default 10 ] [ Range 0 - 100 ]

    • Applies noise to the MB with 0 being no noise and 100 being a lot of noise

    • By default, Jitter alone doesn't do much at high blur samples

    • When used in combination with lower blur samples, notably 5

    • The lower the jitter, the sharper the blur, which leads to more of a banding effect

    • The higher the jitter, the smoother the blur. Compounds the already smooth motion blur with high samples, which may cause artifacts

  3. Blur Samples: [ Default 30] [ Options: 30, 16, 5, 1 ]

    • This value determines the blur samples.

    • The higher the sample, the smoother the blur

  4. Chromatic Aberration - also known as Color Splitting

    • Strength [ Default 0 ] [ Range 0 - 100 ]

      • Determines the strength of the Chromatic aberration effect

    • Method: [ Default Channel Shift ] [ Options: Channel Shift, Additive, Additive Selective]

      • These options determine the blend mode of the aberration.

      • Channel Shift: This blend mode applies a straight RGB shift to the motion blur.

      • Additive: This blend mode adds RGB colors and adds the pixel values on top of the existing values of the affected object.

      • Additive Selective: This blend mode adds pixel values to the full image, both the values below, the chromatic aberration, and the object in motion itself.

        • In layman, the RGB Shift affects all the pixels it crosses paths with.
