band of rings instead of smooth tone?
Im getting a band of concentric rings instead of a smooth even tone in my background.. Anyone know why?

my effects are just spotlight and brightness contrast.
thanks!

you have just witnessed the amazing 8 bits per channel, go to 16 in project settings.

i did. i even tried 32 and it still has rings.

what is your output codec?

hey chris-
using animation but i see it even in the Aft Effects viewer..

AE’s ramp effect is 16bpc. Perhaps you used some effects that aren’t 16.
right click effects box and select show only 16 compatible. -
It’s conceivable that it could be a limitation of your monitor causing the banding, particularly if it’s an LCD. Can you check it on a CRT?

I’ve seen this happen on LCD monitors, while the same project looks fine on a CRT. Can you check it on a different monitor?

I see it too after I download it.

cc spotlight (the version that shipped with ae) is only 8 bpc. cycore does have ‘hd’ versions of their plugins that are 16 bpc, but you’ll have to buy them.
you can try the old trick of adding noise to sort of dither the colors and trick the eye into blending those bands. try a little noise effect (like 5%) on an adjustment layer and see if it helps out.
also, i believe apple’s animation codec is 8 bpc, you might try digital anarchy’s ‘none16’. it’s a free uncompressed 16 bpc codec with alpha channel support… i’m having trouble finding it on their site, but i did find a mac version on version tracker….
upon further investigation, they seem to have sold things to red giant, maybe they’ll have it… not sure if it will be free though.

i tried noise. didnt work. i even tried blurring.
would i need an HD version of spotlight as well as 16 none (didnt see it on red giants site) for exporting?
