Quick Time 7 was tossed into the Utilities folder when you updated to 10.6.

I did not update to 10.6, kid. My newest MBP (17", Early-2011) came already with 10.6.7. What now!? :D

Quick Time X replaced QT7.

No, QuickTime X in 10.6 uses still the old QT7 API, "under the hood". I know this, because i write QuickTime-based software.

AVFoundation is a new technology that first appeared in iOS and has just been included in OS X with the 10.7 release.

The AV Foundation framework appeared first in iMovie for iOS. Final Cut Pro X (https://www.macrumors.com/2011/06/21/apple-announces-final-cut-pro-x-motion-5-and-compressor-4-available-today/) included it first on the desktop OS platform (one month before Lion). That is the reason why FCPX runs also on Snow Leopard (not just Lion).

They replaced it in OS X 10.7 (with AV Foundation (http://developer.apple.com/technologies/mac/whats-new.html#av-foundation)), not 10.6.

AVFoundation is a new technology that first appeared in iOS and has just been included in OS X with the 10.7 release. Apple expects developers to use it instead of the older QT technology for new development.

I guess it's time for Apple to drop QuickTime for Windows as a separate product, fold it into iTunes and remove all extra features like QT Player, control panel and internet plugins. And especially get rid of the absurdity that is QuickTime Pro.

The thing about QT7 Pro, that QTX does not do is sequence of images into a movie, it very fast and efficient, that is why I still use QT 7 pro. Wish :apple: would of added the pro features to QT X

looks like a pretty big update security wise but, I'm guessing i've already got it for Lion then?
Quicktime 7 is absent from Lion unless you specifically download it.

That's not true. Quicktime 7 was replaced with Quicktime X in 10.6, although both are still supported in both 10.6 and 10.7. What you linked to is just a new framework.

It's nice to see that Apple still provides security updates for Leopard. A lot of people still use it, and Apple's recent decisions regarding backwards compatibility have bothered me a bit. (Rosetta's demise, as well as Xcode 4's inability to develop for anything before 10.6, and Apple's removal of Carbon tools from Xcode 3).
