IS THERE REALLY A DIFFERENCE IN VIDEO QUALITY BTW CMOS AND CCD SESNORS?
I’m rattling confused. Last weekend, I bought a Canon 2MB CCD camcorder and I wasn’t mitigated with the recording calibre (can’t rattling feature what’s compassionate though), and today intellection of effort a Sony camcorder that comes with 3MB CMOS sensor. Just same to ask whatever (i wish they’re not “stupid”) questions:-
a) Is there rattling a disagreement between a CMOS and CCD sensor?
b) Or what most the calibre from 3-CCD sensors on JVC / Panasonic camcorder?
Thanks in advance.
yes
CMOS is noisey and CCD isn’t, so you can make a camera with less electronics.
CMOS requires a design circuit to limit the noise of the sensor.
I’m not exactly sure what’ you’re talking about in terms of quality.
I’ve never seen a significant quality difference between a $3,000 3 CCD camcorder and a $300 1 CCD camcorder.
The quality difference comes with less compression, faster recording speeds, large CCD chips.
Here you’re talking in the $10,000 range
Also the lenses are better.
You get a Panasonic 1/2″ 3 CCD camcorder with an Angenieux 12-120 zoom lens for $12,000 that records in DV CAM 50 or DV CAM 100 and you will start to see a difference.
You are also capturing more like 700 lines of resolution instaed of 520 lines.
520 lines is about the limit of Mini-DV at the speed it runs and the 4:1:1 compression rate and the 7:1 AVI compression.
Now you double the recording speed and switch to 4:2:2 color with a 5:1 compressioin rate AVI file and you have a better quality image.
Were talking DVCAM100 here and you get about 20-30 minutes recording time on a cassette twice the size of a Mini-DV.
You go to what George Lucas uses, which is a special recorder with 4:2:2 or 4:4:4 and zero compression on the final file and you are now talking 1,000+ lines of resolution.
But you are also spending $50,000+ on a camera that requires a separate recorder.
And you’re talking a Tech or Engineer that sets it up with a Tektronics Monitor.
Your talking a set of Taylor Hobson Cooke lenses, Panavision Lenses.
You’re talking a D-1 or D-3 system.
Canon are generaly very good, so it may be your camera’s faulty or it may not be the camera at all. Was everything on automatic, or if you had manual settings, were they correct? I was bitten this way a couple of weeks ago when I switched my autofocus off by mistake!
