I was pointing out that there's a compressed AIFF format that does 4:1 compression that's a standard part of QuickTime (although you need Pro to access it via the QT Player).

You will only have access to its features (including the audio export options being discussed here) if you have a QuickTime Pro 7 key. 10.6 has two separate QuickTime Player applications. The one called "QuickTime Player" in Applications is the brand new player for QuickTime X. It is targetted at newer video formats and has some basic editing and export capabilities whether or not you have QuickTime Pro. It doesn't have access to the standard QuickTime export features. The one called "QuickTime Player 7" in Utilties is the old QuickTime Player which has all the features of QuickTime Player from earlier system versions. It requires a QuickTime Pro key to enable its editing and export functions. QuickTime Player 7 is not installed by default, except in the case where you upgraded to Snow Leopard on a system which already had a QuickTime Pro key entered. Otherwise you can choose to install it as a custom option when you install Snow Leopard, or install it after the fact using the Snow Leopard DVD. In either of these cases you would need need to enter a QuickTime Pro key to enable its pro features. The QuickTime Pro key only affects the operation of the QuickTime Player 7 application. Other video editing software (including some versions of iMovie) can provide access to full QuickTime (7) editing and export features whether or not you have a QuickTime Pro key. (This is the same as earlier system versions.) -- David Empson dempson(a)actrix.gen.nz

For some reason I initially thought that 10.6 included a Pro version of QT7, but that's not the case. > 10.6 has two separate QuickTime Player applications. > > The one called "QuickTime Player" in Applications is the brand new > player for QuickTime X.

Fairly sure I also said pretty much the same thing, but thank you for confirming that the Pro aspect basically unlocks the QT Player app and nothing else. I was a tad hazy on that bit.

I saw Jethro Tull many years ago, in a very small intimate venue, and the mix was dull and lifeless, Ian's voice sounded like it was coming through three layers of wool jumper. Very disappointing. I put it down to age (theirs, not mine), but I've since heard them infinitely more crisp and bright so I guess it wasn't due to decrepitude. -- Pd

The codec is stored in the header of the file. Even uncompressed AIFF files can be marked as being compressed. The original AIFF format was big-endian, naturally, as the then processors were big-endian. Which the switch to little-endian Intel processors it required a change of the AIFF format, but of course there's no endian support in the standard AIFF headers. To get around this little-endian issue, Apple introduced a fake AIFF-C codec called AIFF-C/sowt, which is nothing more than a little-endian standard AIFF. The term 'sowt' is just twos backwards, you see! |
