With a max resolution of 5760 x 3840, I think there might be something to do with it being perfectly divisible by 1920.

5760/1920=3

Someone can shed more light on why this is significant since I don't know too much about line skipping or binning or whatever...

From Chuck Westfield
"I’m curious about the move up to 22.3 mp – it isn’t that much of a move from 21.9… so why change at all?
CW: There were several considerations, but the biggest one had to do with the substantial improvement of video quality along with overall image quality."

Chuck Westfall of all people should know that the 5DII's sensor is 21.1 megapixels, not 21.9.

forget pixels. More important is DR. And canon has done the right thing to improve it by 2 stops over the MKII

I don't know or care much about video or pixel binning, but would have been happy with 15 or 18 MP and 10 FPS and super dynamic range, but then I guess it would be stepping directly on the toes of the 1Dx at a much lower price.

Meh

I imagine he does.  In the quote of the conversation above... Chuck starts talking where you see "CW".  The mention of the 21.9 was from the interviewer or a typo by whomever transcribed it... I didn't actually read or listen to the interview just pointing out what is posted here.

the camera takes pics at 3:2 while video is at 16:9

Full hd resolution is 1920x1080

3x3 pixel binning would yield 5760x3240 at 16:9

16:9 / 3:2 = 1.851.... (lots of decimals)

1.851.... x 3240 = 3840 which is the exact pixel height of the 5D3

5760x3840= 5d mark 3
