new with Tiger i would imagine. intermediate.. meaning maybe in between coreimage/corevideo and the codec?

Used in iMovie because working with HD is too resource intensive.

Me three...

This isn't showing up on my software update (nothing has yet in Tiger) but I did find it on the Apple site along with this update for the Pro Apps

Pro Application Support 3.0 (Mac OS X 10.4)
This update improves general user interface reliability for Apple’s professional applications. It is recommended for all users of DVD Studio Pro, Final Cut Pro, Logic Pro, Logic Express, Motion and Sountrack.

Showed up in my Software Update (using Tiger) just fine. Installing it now.

Now I REALLY wonder why iTunes 4.8 isn't showing up in Software Update?

Apple Intermediate Codec (AIC) is what HDV is transcoded to on-the-fly when importing into iMovie 5 and FCE 3 (iMovie HD and Final Cut Express HD).

It's slightly bigger (file-size wise) than DV but it's a bit smaller (file-size wise) than DVCProHD. The resulting files are a little over 2x bigger than the native HDV that's on the tape.

AIC is a compromise between bandwidth and quality.

Rod Rod, since you seem to know what you're talking about, why would they use something that's twice the file size than the original HDV? Is it due to HD requirements on processors?

I installed it regardless, and am really curious why iTunes 4.8 hasn't shown up yet.

Please, please be more descriptive in subject lines. "New In Software Update" could apply at any time. It's not much better than "Read Me".

It's because AIC is easier on the CPU than the native HDV (MPEG2 transport stream).

For a parallel example, H.264 HD video will play back choppy on a 1GHz PowerBook. However, using QT Pro and exporting the file to DVCProHD will give you a file that plays back with no dropped frames. The file itself will be way bigger than what you started with, of course.

FCP 5 has native HDV support but it requires some serious hardware for any sort of realtime effects in that codec - more so than DVCProHD (the Dynamic RT will help for lower-powered systems, of course).

A little off-topic, but where'd you get that desktop background?
