I also have Quicktime (player) 10.2, creation date August 2012, and I'm running OS X v. 10.8.3 on an MBP 15" retina; I want to buy QT Pro but the Apple web page for Quicktime Pro says QT Pro registration codes don't work with Quicktime X. They do not offer any other path for me to get Quicktime Pro. I don't plan to buy a code for 30 bucks unless it's likely to work.
Can anyone advise me? Is Apple abandoning development of Quicktime? Surely not...
Thanks Kirk for 'quick-time' response: going to try it now.
It still feels strange to have to go backwards in order to go forwards, but I guess we have to live with it.
Quicktime is one of Apple's greatest technologies ever, so I hope they don't neglect its maintenance and development; that's all I can say.
QuickTime X seems to be the future development for Apple and it has features not found in version 7.
Likewise, QuickTime Player 7 with the "Pro" license has a lot of features not (yet) available in QuickTime X. Most notable are the extensive export options, movie property editor, & "old school" window style with easy to set in & out timeline points that don't block the image.
But because it is a 32 bit application it is much slower for some things than QT X, most notably playback of HD movie content.
So I use QT 7 for editing & exporting and QT X for playback-only stuff.
