Well, one thing to consider beside codec limitations is that often in a green-screen set-up a shallow DOF is not desirable, rather the opposite. So a small sensor camera can actually have a advantage over a vDSLR here as you don't need to pump up the light levels as much to step down the aperture for a deeper DOF. For example hair strands slightly out of focus are a ***** to key even at 4:4:4, they tend to pulse in and out of the matte with a life of their own.

most of my work involved compositing, and even though i ordered the 7d I had my fears. seeing this totally erased those fears.
Thanks for posting.
Fur looks nice, but I couldn't help but notice artifacts on the whiskers. Now most blondes don't have whiskers, but they do have stray hairs. I guess you can always choke the stray hairs out.

two schools of thought here:
if by artifacting you mean the aliasing and brief reflections, then yes its a little funny.
if by the fact that you can actually see the whiskers, I would consider that a plus.
DV and even DVCProHD used to just produced one huge blurry pixel where that whisker would be.

Ill post more stuff soon.

OMG, I've seen it all now. :cheesy::cheesy::cheesy:
I don't know the term for it, but sometimes parts of the whiskers become big white blocks. This is distracting, and it shows that you've manipulated the image. I'm not saying that DVCPro HD can do better, but for me, I would mask out the whiskers rather than show the flashing.
So I agree that it is a plus that you can see the whiskers, but until you can see it correctly, it is not an advantage.

I thought the flashing was from the whiskers getting a little shine from the lights, i.e. the whiskers are molded plastic and are reflecting the lights back at the camera, which creates the white blocks for a moment. At least that what it looks like to me. It doesn't look like the codec is failing.

If you are going to be chroma keying in a studio, I would recommend a camcorder with an uncompressed HDMI out and capture with the Black Magic card. You aren't going to get much cleaner than that, and you want the BG to be in focus for tracking markers when necessary.
One of the Canons like the HV-20, 30, or 40 would be a good choice. I think the HVX-200, 170 are uncompressed out of the HDMI as well.
You'll get the fine detail of smoke and hair better with these than anything else in the price range.

I don't think the 7d would be ideal since you wouldn't need a shallow depth of field for green screening or compositing. And its 4:2:0 color space and aliasing could be issues. However, it'd still be miles better than standard def mini-dv, which is a nightmare even with something as great as dvmatte.

Yeah it was the guys over at the Syndicate, the same fellas who make the Prime Lens mount for the 7D. here is their blog, as well as the info regarding the Maxtor HDMI capture setup.

Its the best sharpness 7D can do or something is not right wit the lens?
Looks like upscaled SD

I think it was you who asked this in another post. It's kind of misleading because that's not the actual image size... If in doubt download the commercial they shot that's on their site. The commercial is rendered at 1024x576 but looks pretty sharp to my eyes. But I still need to see an HD version.
