Quicktime HD Gallery

Apple maintains an HD Gallery on their website. This gallery features Quicktime videos of movie trailers and other documentary-style shorts that are available in a variety of formats. These videos are encoded using the H.264 codec (a subset of MPEG-4), which is able to achieve very high data compression without loss in picture quality. Apple has a page of recommended systems for playing back this video of course.
