I don't think it's a different frame rate rather it's just that the two are not synced

Something is different in the settings of the two cameras. Framerate? Notice the difference in speed of the turbine on both vids. Am I crazy?

I agree with Josh. Camera setting are here different, the 5D mII pulls up much more details than the Mark III. It is obvious that there is a significant improvement in the red noise reduction, however I am still a bit suspicious about what's been said: "We have gained 2 steps up in ISO compared to the markII" as on this actual footage, footage of the Mark III has been softened, that's why it looks less grainy, but the loss in details can be here neglected.

Well.... the Noise improvement, and moire its very noticeable on the 5DmkIII. in regard of the appparent softness the newer model is showing. i really think the camera went out of focus. 1. Narrow Depth of Field 2. PowerLines show out of focus characterisitcs on the 5d3 footage. u can tell when something is soft and something is sharp. 3. new focus system, ergo more chance to fail on camera you are just getting used to. 4.It doesnt make sense... Canon can not kill this feature.... this is why the 5dmkII is the 5dMkii.... not because it can record uncompressed via hdmi like nikon... because of the image quality it produces. I suggest we all wait for well placed daytime 5dmkii vs 5dmkIII footage.

when looking at the downloaded version, pause the side by side, look at the yellow thing painted at the bottom of the turbine, you can see a big difference in detail, sharpness. so to if you look at the branches. if settings on both cameras and lenses are the same this is not a good sign, i have to admit looking at the videos that canon have shown so far the footage seems disappointing and to my eye lacking that 5d 2 "magic something". i hope to be proved wrong in the very near future.

When i saw the demo versions in Canons website i thought quite the same as now: is it real the plastic or more video-like style of the 5d MKIII? Idont know, the MkII was made in an really special moment when the crisis lead Canon to brake the market, also, and as a good Director of Photography said, 5dMkII is an error a fantastic and strange error! We will have to wait for better footage...

Yeah I see it too Eric. I still think even though I can see that. the 3 does look way better. Which will be nicer for those looking to shoot at night. Granted, that alone is NOT going to make me wanna pay an extra grand for not much more than the 2. Least not that I can see.

Rodrigo I hope your right about the 5d3 being out of focus, but it does seem a bit odd that this guy could make such a mistake. Here's hoping its the best dslr to date, when I see some footage comparison done properly by Philip B or someone we know then I'll put my order in.

I'm waiting for a full review at http://www.the-digital-picture.com before I take the plunge. So far, no one has done a reliable ISO-ISO comparison at useable ranges under good conditions, same lenses etc.
