Black and white only
I’m trying to make animations for a scoreboard that only have black and white values.. 2 colors and thats it. Is there a way to adjust after effects pallate to only use black and white and use different patterns of the 2 to simulate greys in the middle?
I want a gradient that has full white and then fewer and fewer white pixels as we get to the black.. simply crushing the levels gives me all white until half way then all black which is not what I want.. any suggestions?

No, AE does not use dithering patterns. Even if it did, it probably would use adaptive 8 bit instead of ordered 2 bit. However, you might have some succes by using posterization in combination with Particle Playground or the Checkerboard pattern effect… You should also try to mangle your image sequence thru Image Ready or Photoshop via automation. They might provide just what you need.

Maybe I am way off as to the effect you are looking for, but I am doing a scoreboard style effect on a project right now, too.
I am getting great results using “CC Ball Action”. It breaks a layer down into..well… balls. If you adjust their size and spacing and add some creative glow effects, it looks perfect.
just my two cents.

how about channel mixer to create your greyscale then posterize to divide it into however many levels of gray you need?

Colorama may help. Create a gray ramp, switch off interpolation and move the triangles around. Experiment.

I can’t think of anything in After Effects that does dithering. If all else fails, you can export to an image sequence and batch convert it in Photoshop. There was a recent tutorial on creating a slideshow that used Photoshop batch processing.

If you are looking for a lights on/lights off thing try searching the archives for “ticker” I seem to recall a method (including a project file) that did just such a thing. (There was one in 3d around a corner and one that was straight up on/off)

I put this off for a while as other things piled up. But I’ve figured it out. As you may know the Oakland A’s and Raiders scoreboard will only display the lights as on or off. Which makes creating grey values quite difficult. However I have figured out a way
1. create after effects animation
2. output as jpeg sequence
3. batch action. Convert to Index mode. Pallette-Uniform, Colors-2, No Transparency, Dither-Diffusion, Amount-100%, No-preserve Exact Colors. OK. Convert to RGB mode
4. import converted jpeg sequence back into after effects.The before and after result
