Gradient

Yes, cool, useful plug-ins really can be this inexpensive. Gradient! allows you to create 16-bit, 6 color gradients within Adobe After Effects. It gives users unprecedented control over the look and animation of the gradients. Gradient! offers many features expected from a gradient tool: transparency for all colors, direction dial, built-in transfer modes, four different gradient types, and the ability to repeat the gradient.

Requirements:

After Effects 4.16.0, Final Cut Pro 3.0
