Your stuff looks great, are those going to be the final background?
I love keylight! it's is the best I've been able to find. Did you shoot in 720 or 1080? as far as the stepping edges I find that you can easily fix that by either blurring the alpha channel slightly by using a channel blur, or do the pre-screen blur that's part of keylight. OR BOTH!
Whenever I shoot greenscreen I shoot 1080, I find the edges look much better with the higher resolution, then later I down-convert it to 720 after it's been keyed and the backgrounds have been put in. I shoot everything else in 720 usually.
But overall I think the HVX is the best camera to do greenscreen with because of its 4:2:2 colorspace which makes it infinitely easier. Just for fun you can do a quick comparison by shooting standard definition dv25 (4:1:1) and dv50 (4:2:2) You can see an incredible difference in the edges with the higher color sampling of dv50.

thanks for the helpful info!
I shot it in 720p/24pn, but I'm doing another green screen project next week so I'll try 1080 and see how that looks. I added the pre screen blur inside keylight and it did help some, as well as the simple choker but I still have a little bit of "flickering". I'll look into the alpha channel blur this weekend because I'm going to fix the end sequence a bit to make it look better, I simply had to turn it in due to the deadline for school. But thanks!
