in the intro to the movie Seven (with Brad Pitt) there is this random flashing that occurs - also - the text is moving very jittery - any idea on how this is done?

Well, in the actual Se7en movie, they used an optical printer and beat it up while it was running.

In After Effects, I could try to emulate the look by playing with blur, levels, position, distortion effects, and applying some fast wiggle and random expressions to all of them.

I've also had a fun time printing titles out on card stock, taping it to a rocking chair and taking a bunch of photos of it.

You might also check out Video Copilot's Twitch plug-in for After Effects. It makes it easier to randomize (or "twitch") a variety of parameters all at once.

One way i like to do this is throw an adjustment layer on your comp, play with the levels, maybe a transform position and scale, colors, get crazy with it...but then throw this script onto its opacity

probability = 9;
r = random(-probability+2,1);
c = clamp(r,0,1);

Math.round(c)*100

adjust the probability # to control how often it glitches. Also if you want to glitch just the text you can use this, this will glitch in the y axis but you can throw the "s" in place of the "value" if you want to move the x as well, same if you want to add a z axis.

probability = 3;
r = Math.round(random(-probability+2,1));
v = clamp(r,0,1);
s = wiggle(10, 400*v);
x = value[0];
y = s[1];

[x,y]
