Any chroma keying stories yet?
 

I'm hoping the 7d will key better than my HDV camera, which isn't so great. Will the high data rate theoretically improve the chances of getting a good key? Who has keyed so far?

Check this:

I have only done one quick interview in our studio with the 7D... and as rush a job as it was one thing was really clear. They 7D footage was WAY easier to key than HDV! I think it has the same chroma sampling as HDV, but there is just so much more information there and less noise which must help quite a bit. So I guess that's good news... oh, and I just used keylight in aftereffects. I hear you can get even better results with some of the other plugins such as dvmatte pro.

I have used a chroma key setup with Reflectmedia and it seems to be the same as my A1. I didn't notice anything different.

Well that's disappointing to hear...
