How do you create this effect?
Posted by Ernie Geefay on March 4, 2009 at 3:48 pmHi
I have a video of a man’s face.
I’d like to use the whites and blacks of fractile noise layer I’ve created to make random parts of the of the man’s face appear and disappear
Any idea how to achieve this effect?Ernie Geefay replied 17 years, 2 months ago 3 Members · 3 Replies -

March 4, 2009 at 4:03 pmThe simplest way I can think to achieve this is to use the fractal layer as a track matte (luma) for the video layer.
If you just want it to affect the man’s face, you may need to use some masking.

this will take the light and dark values of the noise layer and use them for transparency on the face layer. then it’s a matter of animating the noise and adjusting settings like brightness/contrast, scale, etc. within the effect to achieve what you are looking for.
you could do this all on one layer, but it will take 3 effects…
- add fractal noise to the face layer.
- add unmult to create transparency from luminance (free download from redgiantsoftware.com it’s labeled knoll light factory unmultl).
- add cc composite to composite the original face layer back, but keep the transparency
