- Increases the playback reliability of Motion JPEG media

Audio:
- Improves AAC encoding fidelity
- Audio tracks from MPEG video files now export consistently

Application Support:

Downloading now. Hopefully all goes well. Bug fixes and improvements are always welcome in my book.

Hopefully it won't be so sluggish when loading now.

Interesting about the H.264 video encoding - hopefully my EyeTV exports will be not as blocky/faded.

I'm guessing this doesn't pertain to Apple Lossless files because that's what I'm currently ripping my entire CD library with.


No, it's AAC and I'm curious to know more, especially if Apple screwed something up in the past. Wonder if they'll comment on this over at HydrogenAudio at some point soon?

Apple: so incredibly infuriating with releasing useful information that may potentially cast them in a bad light.

I'm curious too. "Improvement" could mean fixing a past audio screw-up (albeit one people may never have managed to hear) or it could mean that software and encoding techniques improve, and Apple is bringing us the latest (which, again, we may not be able to hear).

I'd be interested in some blind listening tests--which I'm sure someone is bound to do soon!

Luckily, I had not yet begun re-ripping my CDs at 256 :)

Can someone confirm this won't break the 7.5 Pro key I bought just a couple months ago?

EXCELLENT. This shows that Apple is more than alive, and that SJ might come sooner that we expect...

A great update on the white MB (for the same price) and even more improvements to the already excellent QT...GO APPLE!

Say what? I can imagine millions of people now cursing at their lovingly-ripped libraries.

Well AAC > Mp3, but lossless FTW. Had been ripping anything I buy with loseless for 5+ years.

Guess today will be iTunes / Quicktime updating / loud speaker testing day.

Don't hold me responsible if I'm wrong, but my understanding is that the key you bought is a Quicktime 7 Pro key, not one specific to 7.5. Past Quicktime 7 updates have not broken my own 7 Pro key — so no, this one shouldn't, either.

Here's the Quicktime 7 Pro key page at Apple, for reference:

When will they fix the inability to play Dolby Digital 5.1 from Apple's own HD TV shows. These work fine in AppleTV, but in PCs/Macs, they play in 2 channel only. Hopefully fixing that will also fix people that use Handbrake to rip their DVDs to MP4 file can get DD 5.1 also.

Just upgraded and mine's still OK.
The key is for QuickTime 7 Pro - I don't think it'll be a worry until Quicktime 8 or whatever is next.

QuickTime X.

Though, I can see Apple dropping the whole "pro" part of QuickTime all together. Plenty of free alternatives that do a better job.

They took out the 'full screen' costs for QuickTime - and the QuickTime video encoding API's are available throughout OS X, so I don't see any point in paying for QuickTime Pro.

Audio:
- Improves AAC encoding fidelity

Does this in any way affect older iTunes store tracks? Or are the store tracks encoded using an entirely different brand of audio codec?

Mine is ok after the upgrade from 7.5 to 7.6 as shown below:

I hope they improved AC3 support so I can easily use Perian + QT Player to export MKV (with AC3 audio) to an MP4 container that my PS3 can recognize.

I had a slight issue with this update. I installed this update, which then automatically restarted my computer. It rebooted and everything loaded as normal. Then I opened Safari, Mail, and iTunes and all crashed instantly. I tried again numerous times and same result. I tried opening up Disk Utility to repair permissions/verify the disk and that also crashed. I was about to dig up my Leopard install disc, but I wanted to try just restarting it. I did and now obviously everything works. I started to freak for a second. It must've just been a caching issue? Maybe for some reason my computer didn't restart a second time and it was supposed to?
