I'm looking to create the effect of TV haze/snow. Similar to what you get if you turn the TV onto a channel that isn't tuned. Probably not too hard. Can anyone explain how it's done or link me to a tutorial please.
The quickest and dirtiest I can think of:
Make a solid thats' 1/4 to 1/2 the size of your comp. Apply the Noise filter. Then scale that solid to fill the frame. Then maybe apply Sharpen to give it a really crisp look.
The upscaling is what makes the noise chunky and more TV like.
Thanks Navarro, will do!
Make sure you uncheck Use Color Noise.
