Colors and Compression for huge LED wall visuals (avoiding banding and general ugliness)

Hi all!

Anybody here with experience creating motion graphics for huge LED walls? How do you deal with banding and blockiness in the darks?

We just had a big event with loads of video on a ginormous LED wall. It all looked great except for the darker videos...there was quite a bit of banding there. I'd like to improve that for the next time we do this. Are there any general guidelines about levels, compression, colors, etc. that I should keep in mind for next time?

Cheers,
Lori

Was the gamma on the LED wall possibly not set properly?

As was as the graphics design goes, make sure to keep away from single color gradients, add a little bit of a secondary color to ramps.
Second, add noise to gradients to keep banding at a minimum. In After Effects, that would be the grain effect.
