GlowNoise

Sapphire’s GlowNoise filter generates glowing light from areas of the source clip that are brighter than the given threshold. The glows are also attenuated by a solid noise texture to give them a noisy or grainy effect. If the Jitter Frames parameter is positive, the noise will be regenerated for each frame for a fizzling look. If Jitter Frames is zero, two noise textures are combined and slide over each other at a rate depending on the Spread Speed.
