maybe you can help with a question-
i know there is no right answer per se, but which camera would record a better image-
a cam with 1/2" CCDs recording at 25MBs in a 4:2:0 color space or a cam with 1/3" CCDs recording at 100Mbs in 4:2:2
everything else being equal

without even thinking twice
1/3" CCDs recording at 100Mbs in 4:2:2 which is Panasonic's DVCpro 700 and 900 series
Now the type of ccd will also have an impact, Mind you there is only HAD CCDs in 1/2" though I don't think they are made anymore ... The last half inch CCD camera I know of was the BVW 100 (mind you there could be others, I just don't know them) Today you'll find two major CCDs in use .. CMOS and HAD ... you'll find HAD on broadcast cameras, SD or HD ... CMOS are much cheaper to produce and ate the CCDs you'll find in HDV cameras, Even the less expensive Canon 300D (Rebel) or Nikon D40 (digital photo SLRs). CMOS are also used for lots of Point and shoot cameras. I can't rrealy get into the techonlogy of it. Let's just say they are less expensive to produce (this doesn't mean a lesser image) .. Hense why your able to get 3 hd cameras at under 1500$ or D-SLRs under 1000$, For the d-slrs other things come into play to reduce the cost. Such as Body sturture and material and the type of prism used.
Please explain what 4:2:0 color space is .. I've never heard that term before
As far as I know a ratio is used to explain Compression (detailing) not color
