Output file has digital junk? 3D lighting issue?
3D solids with 1 light, moving fast with motion blur.
See the bad pixel blocks on top of only the red squares.
I tried different Comp settings and got the same output. i.e. Standard 3D render – Faster and More Accurate – Advanced 3D. I didn’t try OpenGL
Output file is standard Microsoft DV with lower field first. What else could I try to get rid of these bugers? Is it compression or a lighting contrast issue? It doesn’t show while scrubbing the timeline.
Please advise

Looks like a codec issue. DV doesn’t like bright red. Heck, most codecs don’t, from what I’ve seen. Have you tested rendering to other codecs? Is there any chance you can render to another codec for delivery? If not, will those dots even be noticed when the thing is in motion?

… do you have enough Z-axis separation between your red and blue solids? Just a thought — they might be too close.

Reds are at zero and blues are at 74 so what is too close?
A quick render to uncompressed shows no bugers! So the question is what will show on the Mpeg2? I’ll reply with that result later.
If it is the bright red and that’s the color that the client wants then will an broadcast colors effect fix it?

Okay, they’re not too close. I thought they might both be in the same plane.
RGB 255/0/0 will give you fits on TV, so it will need to have its saturation knocked down before it leaves AE. Your client should be made aware of this.
If you don’t have access to a scope, try applying levels, hue/sat and broadcast safe to an adjustment layer over the comp. Levels & hue/sat should be above safe in the effects stack. Set the safe effect to “key out unsafe”. Set levels to output black to 16, white to 235. Make sure your comp’s background colour is something wild, something that you will notice when the effect keys out your hot reds. Scrub the timeline until you find something that the effect keys out. Tweak the saturation if it is too colourful. If you have a hot yellow, try turning the yellow layer towards orange a bit using the hue/sat on that layer alone.
The Hue/Sat might only need to be applied to hot layers such as red — no need to take down a dull blue in an adjustment layer.
Will knocking down the red fix the boogers? Maybe. Try adding 1 pixel of vertical blur to the red stuff.
