Adjusting the shutter angle for motion blur


    Adjust the intensity of motion blur by changing the shutter angle setting. The shutter angle is measured in degrees, simulating the exposure allowed by a rotating shutter. If you are not applying motion blur, shutter angle has no effect.

    The shutter angle uses the footage frame rate to determine the simulated exposure. For example, typing 90 degrees (12.5% of 720 degrees) for 24-fps footage creates an effective exposure of 1/96 of a second (25% of 1/24 of a second). Typing 1 degree applies almost no motion blur, and typing 720 degrees applies a high degree of blur. By default, the shutter angle is set to 180 degrees.

To set the shutter angle and phase for motion blur:

  1. Choose Composition > Composition Settings.
  2. On the Advanced tab, type a value for Shutter Angle.
  3. In Shutter Phase, type a number (up to 360) for when you want the shutter to open relative to the frame start (optional) and click OK.
  4. Note: You can also change the shutter angle for a composition in the Render Queue window. See Changing render settings.
