Strobe Light--AE

This effect performs an arithmetic operation on a clip at periodic or random intervals. For example, every five seconds a clip could appear completely white for one-tenth of a second, or a clip's colors could invert at random intervals.

Blend with Original Specifies the intensity, or brightness, of the effect. A value of 0 causes the effect to appear at full intensity; higher values diminish the intensity of the effect.

Strobe Duration Specifies in seconds how long a strobe effect lasts.

Strobe Period Specifies in seconds the duration between the start of subsequent strobes. For example, if the Strobe Duration is set to 0.1 second and the Strobe Period is set to 1.0 seconds, then the clip will have the effect for 0.1 second and then be without the effect for 0.9 second. If this value is set lower than the Strobe Duration, the strobe effect is constant.

Random Strobe Probability Specifies the probability that any given frame of the clip will have the strobe effect, giving the appearance of a random effect.

Strobe Specifies how the effect is applied. Operates on Color Only performs the strobe operation on all color channels. Make Layer Transparent makes the clip transparent when a strobe effect occurs. This option works only if you place the clip in a superimpose track, apply Transparency, and select the Alpha Channel key type.

Strobe Operator Specifies the arithmetic operator to use when Operates on Color Only is selected from the Strobe menu. The default setting is Copy.
