Set Speed

Set Speed

The Set Speed behavior lets you change the speed (playback rate) of a clip. The speed specified in the behavior begins at the behavior’s In point and exists for the duration of the behavior. The clip continues playing at its default speed after the behavior’s Out point. For example, if the Set Speed behavior begins at frame 60 and ends at frame 300, the clip plays normally until frame 59, plays back at the rate specified in the behavior from frame 60 to frame 300, then resumes its default playback speed at frame 301. You can apply an ease-in or ease-out effect to the speed change.

Adjust this behavior using the controls in the Behaviors Inspector:

  • Speed: A slider that sets the speed of the clip as a percentage. The default is 100% (the clip’s normal speed). A Speed setting of 50% plays the clip at half speed.

    Note: The Speed parameter can be keyframed to create variable playback rate changes.

  • Ease In Time: A slider that sets the number of frames over which the ease-in speed change occurs (from the start of the behavior). The default value is 20 frames.

  • Ease In Curve: A slider that defines the curvature of the ramp when easing into the speed change. A value of 0 creates a sharp transition to the new speed; a value of 100 creates the smoothest ease in to the new speed. The default is 50%.

  • Ease Out Time: A slider that sets the number of frames over which the ease-out speed change occurs (from the end of the behavior). The default value is 20 frames.

  • Ease Out Curve: A slider that defines the curvature of the ramp when easing out of the speed change. A value of 0 creates a sharp transition from the new speed to the original speed; a value of 100 creates the smoothest ease out. The default is 50%.
