Recently I've switched to Mac and am experimenting with different types of compression. I'm awed by the quality of the movie trailers on the Apple QuickTime site. As a novice, I don't know if there is a way to determine what compression strategy is being applied to their trailers. I would appreciate any insights from forum members. Thank you in advance.

You can view them with QT Pro, all the one's I looked at were either Sorenson3 or mp4. Judging from my own expirements, I also believe they use somethign like Sorenson Squeeze to make the sizes even smaller

The Apple movie trailers that use the S�renson codec are typically encoded using variable bit-rate encoding.
The standard codec included with QuickTime only allows for fixed bit-rate encodeing. For VBR, you will also need the S�renson Developer Codec. You can usually get this in a bundle with Squeeze for about $300 or so.

for free video compression, 3ivx is arguably the best codec on MacOS

Having the media you are compressing shot on 35mm film certainly helps a bit....it can stand up to the compression a lot better than something shot on your camcorder
