The Strobe Light effect performs an arithmetic operation on a layer or makes the layer transparent at periodic or random intervals. For example, every five seconds the layer could become completely transparent for one-tenth of a second, or a layer’s colors could invert at random intervals.

This effect works with 8-bpc color.

Strobe Color

The color of the strobe light.

Blend With Original

The effect’s transparency. The result of the effect is blended with the original image, with the effect result composited on top. The higher you set this value, the less the effect affects the layer. For example, if you set this value to 100%, the effect has no visible result on the layer; if you set this value to 0%, the original image doesn’t show through.

Strobe Duration (secs)

How long, in seconds, each strobe lasts.

Strobe Period (secs)

The time, in seconds, between the start of subsequent strobes.

Random Strobe Probability

The probability that the strobe operation will apply to any given frame.
