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
