I'm a bit of a self-educated After Effects fanatic and only recently discovered the lovelyness that is "expressions". I'm usually a bit afraid of all things code, but expressions are just amazing. I still have a long way to go though, because I mostly just wiggle a lot.
Now, I'd like to create an effect, and I would like some help, as I can't get it to work like it should.
I have a 3D scene, a landscape with mountains and trees, and I'd like to have it flash in pure black and white, like a Sin City style lightning.
So I set up an animation preset:
1) Saturation:0
2) Contrast: 100
3) And I guess I need a Invert with a random expression, setting the blending with original being either 0 or 100, but I'm not to sure how to set up that to begin with.
Code: Select all
x=random(1,100)
x<1>99
I do this because I want the parts that become black, alternating with white and vice versa. So, when the landscape and trees flash black, the sky flashes white.
And then I suppose I'd to make all these happen at the same time, but at random points in my timeline, and though it sounds easy, I'm not too sure if it's even possible.
Any thoughts?
