Decay Main Core Decays the main core along with its forks.

Composite On Original Composites the lightning with the original layer using the Add blending mode. When

deselected, only the lightning is visible.

Complexity Specifies the complexity of the turbulence in the lightning.

Min. Fork Distance Specifies the minimum pixel distance between new forks. Lower values create more forks in the

lightning. Higher values result in fewer forks.

Termination Threshold 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.

Main Core Collision Only Calculates collisions only on the main core. The forks aren’t affected. This control is

relevant only if you select Alpha Obstacle.

Fractal Type Specifies the type of fractal turbulence used to create the lightning.

Core Drain 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.

Fork Strength Specifies the opacity of the new fork. This amount is measured as a percentage of the Core Drain

value.

Fork Variation 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

ApplytheAudioSpectrumeffecttoavideolayertodisplaytheaudiospectrumofanaudiolayer.Theeffectdisplays

the magnitude of frequencies in the range you define using Start Frequency and End Frequency. This effect can

display the audio spectrum in a number of different ways, including along a Bezier path of a layer. Apply the effect

to a layer that contains a solid or an image, and that may contain audio.

Note: 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.

This effect works with 8-bpc, 16-bpc, and 32-bpc color.
