Hi there, first post here. I usually spend enough time searching for tutorials and browsing forums that I don't have to ask for any advice, but frankly i'm stumped. I'm sure that sleep deprivation has alot to do with my frustrations at this point.
A client would like a simple slideshow video done but they want a rather unique transition to reveal text and new images. They linked the following video because they would like the exact effect:
What you're looking for is a Gradient Wipe - it's in the Transitions panel of AE. It essentially takes the greyscale values of your gradient, and makes them transition from light to dark, or dark to light, with a few other settings thrown in:
Set up your noise, making sure that there's a nice mix of light and dark greyscale values, and making sure that they more or less transition from top to bottom, or bottom to top in terms of their grey values. If you can't get noise to give you this, you can quickly create a linear gradient in Photoshop, then chop that up into squares and randomize it a bit (yes, by hand), and use that as your greyscale map for the Gradient Wipe.
