visible.
Specifies the complexity of the turbulence in the lightning.
Specifies the minimum pixel distance between new forks. Lower values create more forks in the lightning. Higher values result
in fewer forks.
Specifies the level at which a path terminates, based on resistance in the atmosphere and possible alpha collision. At
lower values, the path terminates more easily when encountering resistance or alpha obstacles. At higher values, the path more persistently
moves around alpha obstacles.
note: Increasing Turbulence or Complexity values causes resistance to increase in some areas. These areas change as conductivity changes.
Increasing the Alpha Obstacle value causes resistance to increase at alpha edges.
Calculates collisions only on the main core. The forks aren’t affected. This control is relevant only if you select Alpha
Obstacle.
Specifies the type of fractal turbulence used to create the lightning.
Specifies the percentage by which the core strength is drained when creating a new fork. Increasing this value reduces the opacity of
the core where new forks appear. Because forks draw their strength from the main core, decreasing this value reduces the opacity of the forks as
well.
Specifies the opacity of the new fork. This amount is measured as a percentage of the Core Drain value.
Specifies the amount of variation in the opacity of the fork and determines how much the fork opacity deviates from the amount
set for Fork Strength.
Audio Spectrum effect
Apply the Audio Spectrum effect to a video layer to display the audio spectrum of a layer that contains audio (and optionally video). The effect
displays the magnitude of audio levels at frequencies in the range that you define using Start Frequency and End Frequency. This effect can
display the audio spectrum in several different ways, including along a mask path.
Jerzy Drozda, Jr. provides a demonstration of the Audio Spectrum effect on the Motionworks website .
Audio Spectrum uses the audio source footage without time-remapping, effects, stretch, or levels. To display the spectrum with such
effects, precompose the audio layer before applying the Audio Spectrum effect.
To prevent other masks on the layer from clipping the output of the Audio Spectrum effect, set their mask modes to None. (See Mask modes.)
This effect works with 8-bpc, 16-bpc, and 32-bpc color.
