Uneven gradient in exported AE files!?
When I export mov’s with ie 3D light, i never can get the gradient (of the light on the background for instance) to make a smooth gradient. Any ideas as to why that is the case?
My exports are 1920×1080 HDV25p.

Without seeing an example image, it sounds like banding. There are tons of posts for what banding is and how to deal with it.
Short explanation is that RGB color space in 8-bits only has a limited number of colors. (When you compress it for web – such as using h.264 codecs – it makes that issue even worse.)
Short solution: add noise. It’ll make your video look more realistic anyway.
Two ways to do this off the top of my head.
1. Create a solid at 50% grey, add noise, crank it up to 100%, turn the layer’s opacity very low. Somewhere between 2% and 5% usually works. Switch color noise off or on and scale the layer depending on how you want it to look.
2. Add Fractal Noise to your background layer and turn the blend with original option way up to about 97%-ish.

anyway, thanks a lot! this makes sense, and finally i’m rid of these nasty “lines”…!

A simple way to add noise to your gradient is just to use the scatter effect. It’s quick and’ll get er’ dun
