Can DSLR Video cameras do chroma keying?
-
True, it may not be. I’ll test with the gear I have and consider if it’s worth the money to upgrade, but I’ll probably come to the conclusion that it isn’t at this point. I just hope I can get some decent keys with my current toy. 😉

After some tests, that didn’t turn out perfect, I still got an idea about what can be done. Have a look at this youtube clip from the experiment to see the results and some comments on this on the voice over. It’s actually my first 720p youtube upload too which seemed to work just fine, nice!

FWIW just finished a job that was shot with 3 Canon 5D Mk IIs all green screen.
Best keys we’ve ever pulled. I am not joking. We had talent behind plexiglass smoking a pipe that we were able to key through. Simply amazing.It’s not just the codec it’s the lens and the sensor as well. A big sensor means little noise. Great glass means clean images.
The chroma keys were performed in Final Cut Studio and Adobe After Effect with Primatte Keyer 4.0.

i know its been a while since the thread was started but if anyone can explain to me how a canon 5d, 7d or 60d are different when it comes to shooting video?

A little off topic for this thread… but here we go. The biggest differences between the cameras you mentioned come to sensor size and convenience features inside the cameras. I don’t know that I will hit everything here… but here are a few.
The 5D Mark ii is a full frame sensor. The 7D and 60D are 1.6x crop sensors. This means that the field of view of a 50mm lens on a 5D Mark ii is equal to what you would get on a 35mm film camera. Because the sensor on the 7D and 60D is smaller it doesn’t capture the entire image projected by the lens and a 50mm lens is cropped. The effective field of view is equivalent to a focal length multiple of 1.6x on a 35mm camera. Our example of a 50mm lens on a full frame would look more like 80mm (full frame) on the 7D or 60D.
I haven’t used the 60D, but I think its IQ is very similar to the 7D. I own both the 5D Mark ii and 7D. Both cameras are very good, but the 5D Mark ii has less noise at higher ISO’s. It becomes most noticeable to me over 1250 iso. This is due to the full frame sensor on the 5D. Larger pixels.
Otherwise, between the 5D Mark ii and the 7D, the biggest things that stand out in my mind are… The 7D can shoot 720p60. The 5D does not shoot this format. The 5D has a histogram for setting exposure. The 5D allows you to manually set an audio level from within menus. Not convenient but something you cannot do on a 7D. The 7D has a dedicated switch for video/photo modes. The 5D has a button to enter live view and you need to set the live view mode up within the menu. The 7D has a dedicated video record button. The 5D uses the center button in the navigation wheel thing to start and stop recording.
The 5D is more expensive than the 7D. They have similar build quality. In general IQ is comparable across the line. Fast quality lenses are important. I shoot with several primes that are f/1.4-f/2.0. I also use a few f/2.8 zoom lenses. Mostly Canon L glass.
