Keylight Fine Tuning

I just had my first experience using Keylight (I know, we're a little behind the times) and I'm amazed at how powerful of a tool it is. However, I am still having some pixelation issues.
I created a loose matte around the talent because she moves slightly while talking. Then I applied keylight to the remaining greenscreen elements. There are still some pixelation issues within the mask.
Since this was my first experience with keylight, I'm not entirely sure what adjustments I can make to try and soften/eliminate the artifacts in the mask. Outside of tightening up the mask and animating it as she moves, are there any adjustments that I can make within keylight to help get rid of some of the pixelation?

Sorry, I forgot to mention that we taped on DVCPro, and the segment was imported into AE as a quicktime file. Hope that might help a little. I know that the digital format isn't going to provide the best keying in the world, but I'm just curious about keylight. Thanks!

...DVCPro 25 or DVCPro 50? You'll get a MUCH better key out of the second one.
If you haven't done the Keylight tutorial provided by The Foundry, you really owe it to yourself to do so. It'll help you learn how to adjust the controls in the plugin.
My AE machine is currently rendering, so I can't get to keylight to look at the terminology they use, or I'd give you a quick lesson.
Check out the tutorials on the COW. I'm pretty sure there's one on keylight basics, which can help.

this may or may not help but i exported a qt from avid xpress pro using the dvcpro codec and imported into ae, applied keylight and had terrible artifacts around my subject. i then tried exporting from avid using the avid dv codec and the terrible artifacts around the subject went away. so you may want to experiment with different codecs.
