hello, I'm using a spot light on a solid colour layer in after effects, moving the light from one side of the comp to another. I'm getting really nasty banding occurring which i cant seem to get rid of, tried blurs etc. Anyone come across this problem before and is there any way round it.
Thanks in advance y'all.

full res, and best setting. looks fine on an apple cinema display, output through a broadcast monitor all the banding shows up

one of the other designers here started getting weird banding on his broadcast monitor that didn't show on his computer monitor, think it was because of his graphics card for the broadcast monitor but he's not here so i can't ask

I think this is due to what vespa said, I am quite familiar with a variety of graphics cards can you tell me which one you are using to output, also is it going through a legaliser?? and can you tell me what color is banding as some frequecies of colors can make a dogs dinner of your picture.

also can you tell me what codec you are using

thanks chossy, i'm using a kona sd card, and yes i am going through a legaliser, codec is blackmagic 8 bit, its a bit of a strange one, seems to be really bad on reds and not so bad on other colours. not sure it is the card as i can see the banding on a qt viewed on a crt monitor.

i think the problem is to do with your graphics card. unless your using 10-bit card you will get a banding problem. or that's what i've been lead to believe.

yep it's a bit issue I think, if you are using ten bit images and use an 8 bit card you get an effect called quantisation I think it is called this is the 'banding' you are referring to it happens on dithered images what I suggest is that you convert all your origional images or settings to 8 bit then when the card plays them out it should be ok.
Legalsiers also can create this problem when they think there is too much gamut but I would say it is the ten bit to 8 bit issue.
