Audio Layer The audio layer you want to display as a waveform.
Start Point, End Point The position at which the waveform starts and ends, if Path is set to None.
Path If set to None, the audio waveform is displayed along the path of the layer.
Displayed Samples Number of samples to display in the waveform.
Maximum Height Maximum height, in pixels, of a displayed frequency.
Audio Duration Duration of audio, in milliseconds, used to calculate the waveform.
Audio Offset Time offset, in milliseconds, used to retrieve the audio.
Thickness The thickness of the waveform.
Softness How feathered or blurry the waveform appears.
Inside Color, Outside Color The inside and outside colors of the waveform.
Waveform Options Mono combines the left and right channels of the audio layer. Nonstereo audio layers play as Mono.
Display Options Digital displays each sample as a single vertical line connecting the minimum and maximum source sample. This option
simulates the display used on digital equipment. Analog Lines displays each sample as a line connecting the previous and next sample from either
the minimum or maximum audio source sample. This option simulates the retracing seen in the display of an analog oscilloscope. Analog Dots
displays each sample as a dot representing either the minimum or maximum audio source sample.
Composite On Original Composites the audio waveform with the original layer using the Add blending mode. When deselected, only the audio
waveform is visible.
Beam effect
The Beam effect simulates the movement of a beam, such as a laser beam. You can make the beam shoot, or you can create a wandlike beam
with a stationary start or end point. The beam looks best when motion blur is enabled and the shutter angle is set to 360.
John Dickinson provides a video tutorial and example project on the Motionworks website that demonstrate the use of the Beam effect.
This effect works with 8-bpc, 16-bpc, and 32-bpc color.

The Length control specifies the length of the beam based on a percentage of the Time specified. For example, a setting of 100% means that the
visible beam length is at its maximum when the Time control is 50%. Time specifies the time of the beam’s travel from start to end as a
percentage. The 3D Perspective control uses 3D perspective based on start and end thickness if Time is animated.
Cell Pattern effect
The Cell Pattern effect generates cellular patterns based on cellular noise. Use it to create static or moving background textures and patterns. The
patterns can be used in turn as textured mattes, as transition maps, or as a source for displacement maps.
John Dickinson provides an example project on the Motionworks website that demonstrates the use of the Cell Pattern effect in a seamlessly
looping background animation.
Richard Harrington provides additional information and examples for using the Cell Pattern effect on his website .
