The pictures are hosted on CoralCDN. That site is still up, and it doesn't say anything about the .nyud.net:8080 suffix having changed, so I guess it's just temporary downtime.

Your images for the comparison: http://boredzo.org/codec-comparison are not appearing - I'm getting server not found errors for the pictures' host http://boredzo.org.nyud.net:8080/codec-comparison/screenshots/ishowu-codecs.png

I remember Apple pushing Pixlet as a lossless codec, turns out it is a lossy codec afterall I guess. Thanks for such a rigourous investigation :)

Ah, that makes sense. And you're welcome. ☺ By the way, you don't need QT 6 for “Embedded Cocoa Frameworks”. Sorenson 3 was introduced in QuickTime 5, and PureVoice seemingly was introduced in QuickTime 4 (some sources claim 3, but I can find nothing at Apple's site to corroborate that). All versions of OS X come with QuickTime 5 and later, so I think everybody who watches that movie already has everything they need.

I seem to remember for the Embedded Cocoa Frameworks vid that QT6 didn't have H.264 yet and thus Sorenson 3 was the best filesize-wise. Nowadays I record in Animation, edit in Component Video and output to H.264.

Thanks for the codec investigative legwork!
