After Effects Banding

I see some banding on my comps (only on my laptop, not on my desktop), I haven't render anything yet, but it looks pretty bad.
I saw a tutorial on Grayscale Gorilla that shows you how to get rid of it if you are using ramps
http://greyscalegorilla.com/blog…But I'm using solids with circular mask, is there anything under comp settings I could be doing to get rid of it?
I would appreciate the help!

Check the settings on your laptop monitor. Check the AE project to see if it is in 8bit mode or 16 bit mode. Do some render tests see what it looks like on both machines.

Gminor, where do I check the 8bit/ 16bit thing?
is it under preferences? I think I've seen it before but don't remember where, never used that feature before :(- http://help.adobe.co…Julesvm
- bottom of the project window on the left (will say 8bpc - click to change) :]vivid

keep in mind also how you will be delivering this content. if it's compressed and on the web, then changing the colour mode to 32bit, etc, won't help.

Try and do as much as you can without relying on noise - you'll loose noise straight away and get banding and pixelation when compressed for the web.

thanks guys!
I don't really mind what happens after I give it to the client, if they want to compress it and put it on a 640 by 480 I won't have control over that. My concern was mainly directed to my macbook pro showing banding when I'm working on the project inside after effects (prior to render) on my desktop I open the same project and it doesn't happen.I think there's some setting on after effects in terms of display maybe? or maybe the monitor on the imac just has more color depth?

The Genarts Sapphire Deband spark does a reasonable job.

...given me my fair share of head-aches.
Follow the advice above (checking bit settings + testing on other devices) but sometimes I admit defeat. All depends where its going - I did some titles for a tv program a while back that looked fine everywhere until it was broadcast...its a fine science really Best of luck :]
- Yep. Once it leaves your hands and is compressed to something like a low bitrate mpeg2 for broadcast you have no control.jamesjohnston

- yep - no mater how much time you spend perfecting things! :]vivid

Note: Ramps often don’t broadcast well; severe banding occurs because the broadcast chrominance signal doesn’t contain sufficient resolution to reproduce the ramp smoothly. The Ramp Scatter control dithers the ramp colors, eliminating the banding apparent to the human eye.

90% of the time you just need to use noise.
switching to 16 bit or 32 isn't going to fix a regular gradient, it'll fix banding from stacked blend modes over it however.
