Video: High Definition Trailers
I'm really into movie trailers. I like to download them to my computer and show them to friends at parties and conventions, or associates at business meetings, for that matter. For quite a while, Apple has been my staunch ally in this effort, putting almost every movie trailer of note online on their site in high quality, easily downloadable Quicktime movies.
Now, it may be that they've gone too far.
With last week's release of Apple's new OS, Tiger, they've included a new version of Quicktime. (Version 7, for those keeping track). One of the things introduced in the new version is a video codec called H.264. From wikipedia:
The intent of the H.264/AVC project has been to create a standard that would be capable of providing good video quality at bit rates that are substantially lower (e.g., half or less) than what previous standards would need (e.g., relative to MPEG-2, H.263, or MPEG-4 Part 2), and to do so without so much of an increase in complexity as to make the design impractical (expensive) to implement. An additional goal was to do this in a flexible way that would allow the standard to be applied to a very wide variety of applications (e.g., for both low and high bit rates, and low and high resolution video) and to work well on a very wide variety of networks and systemsNow, with each movie trailer for a movie I'm really interested in, it can sometimes be hard to resist the temptation to go through the trailer frame by frame, analyzing

And my lowly 867Mhz G4, so good at so many things, is totally and completely unable to play them at speed. It drops frames like crazy. If I want to peek at the all the HD goodness that Apple is offering, I practically have to do it one frame at a time.
