Flicker

Scales the colors of the source clip by different amounts over time for a flickering effect. The pattern of flickering can be random, a periodic wave, or a combination of the two.

In the Sapphire Time effects submenu.

Flicker

  • Source: The current layer. The clip to be processed.
  • Load Preset (Push-button) Brings up the Preset Browser to browse all available presets for this effect.

  • Save Preset (Push-button) Brings up the Preset Save dialog to save a preset for this effect.

  • Amplitude (Default: 0.2, Range: 0 or greater) Scales the amplitude of all flickering.

  • Rand Luma Amp (Default: 1, Range: 0 or greater) The amplitude of smooth but random flickering affecting the brightness.

  • Rand Color Amp (Default: 0, Range: 0 or greater) The amplitude of random flickering affecting the color channels independently.

  • Rand Freq (Default: 30, Range: 0 or greater) The frequency of the random flickering. Increase for more variation between frames. Decrease for slower flickering.

  • Wave Amp (Default: 0, Range: 0 or greater) The amplitude of periodic wave flickering.

  • Wave Freq (Default: 5, Range: 0 or greater) The frequency of the wave flickering. Increase for faster flickering, decrease for slower. This has no effect if Wave Amp is 0.

  • Wave R Phase (Default: 0, Range: any) Shifts the wave pattern in time, for the red channel.

  • Wave G Phase (Default: 0, Range: any) Shifts the wave pattern in time, for the green channel.

  • Wave B Phase (Default: 0, Range: any) Shifts the wave pattern in time, for the blue channel.

  • Red Amp (Default: 1, Range: 0 or greater) Scales the amount of flicker applied to the red channel.

  • Green Amp (Default: 1, Range: 0 or greater) Scales the amount of flicker applied to the green channel.

  • Blue Amp (Default: 1, Range: 0 or greater) Scales the amount of flicker applied to the blue channel.

  • Brightness (Default: 1, Range: 0 or greater) Scales the brightness of the result.

  • Seed (Default: 0.123, Range: 0 or greater) Used to initialize the random number generator. The actual seed value is not significant, but different seeds give different results and the same value should give a repeatable result.
