I have read conflicting reports about if the new AIR models have FaceTime in HD or not? what is the real difference and is it notable cause i have the 13 pro i7 and cannot really tell the difference compared to my 13 pro model before this one...
Actually yes FaceTime on the 2011 MacBook Air is capable of HD. The built-in isight is not capable HD so you would need to use a USB camera that is HD capable.
It's capable of projecting an image at 2560x1440 resolution, but that doesn't really matter at all: the native resolution is not HD, so it's simply expanding a low-res picture. It'd be like finding a thumbnail picture and expanding it 5 times in size. You don't get any more detail. You simply blow up a low-detail picture in size, so it's a large low-detailed picture.
The FaceTime camera is decent at best. And not good at worst. I wouldn't call it bad... it's just a notch up from that.
The FaceTime software and the iSight camera are two separate things. Like I previously said the FaceTime software is fully HD but to achieve that you have to use an external USB HD camera. I never said that the iSight camera was HD, in fact I even said that the iSight camera was not capable of HD. The OP asked if FaceTime was capable of HD not if the iSight was capable of HD. I answered the question he asked and the question that he didn't but intended to.
It is very obvious that the original poster is asking if the FaceTime camera is capable of HD video: And it's not. Your answer was misleading in the way you articulated yourself.
On Apple's website, they refer to the "iSight" as you call it as a "FaceTime Camera": http://www.apple.com/ca/macbookair/specs.html. So I don't know where you're getting this "iSight" terminology from: that said, I'm a new Apple purchaser, so maybe there is an alternative name for the camera. However, I've never heard the term "iSight" when reading my Air's manual. I've only seen the camera referred to as "FaceTime Camera".
So, for future reference, don't refer to a piece of hardware as software.
If you say "FaceTime", when we're talking about hardware, don't follow up with a defensive post at me because you were talking about software when you referred to the word "FaceTime".
It's rather obvious that when you hook an HD camera up to a computer that you can get an HD picture... I think even computer dummies know that.
Fact of the matter is this: You're getting into an internet rage here, and spamming the OP's thread. You failed to call the camera what it is: It's a FaceTime camera. It's not an iSight camera. That would be like calling an i7 processor a Core 2 Duo. You're simply wrong. And finally, the OP was asking if the FaceTime camera can do HD Video: It can't. Getting off-topic talking about how the FaceTime software can handle HD video is blatantly obvious. If you feel it isn't, then well... be happy with yourself, I suppose?
Let's not get off-topic. Others have answered the OP quite clearly and concisely.
