Anyone notice that since 6.3 came out the trailers that have been released since then are all fudged up like they are interlaced? The old ones work fine...what gives?
They are slightly different, but close enough for comparison. You see a lot more jaggies and artifacts in the MPEG-4 version, while the Sorenson 3 version looks smoother over-all. Also note that Sorenson 3 fools around with the contrast of the video...the darks get darker and lights get lighter...
I just noticed the same thing. The Seabiscuit trailer looks like garbage in some parts!
I think this might be an unfortunate side-effect of Apple switching from Sorenson 3 to MPEG-4 to encode their trailers. What gives? It's not like they're saving any bandwidth, since the new trailers still weigh in around 25 MB.
Hmm. QT for Windows is even stranger. In Mozilla, the Sorensen film plays back just fine. The MPEG-4 looks like a time-lapse of a Jasper Johns painting in a microwave.
In IE, except for a jitter at the beginning, the MPEG-4 movie looks fine. I didn't notice any radical difference in quality, but I admittedly wasn't looking closely. There were a few areas with what looked like pretty obvious interlacing.

So whoever encoded these trailers either accidentally used interlacing
or
interlacing helps keep over all video quality up and artifacting down at the expense of frame detail.

[Looks like Eugene beat me by a few seconds!]
they look so bad in high movement parts and so much pixel sticking occurs especially in the new 2 fast 2 furious trailer
