Quicktime X is the new version that will be comming to Snow Leopard. Quicktime X is re-built from the ground up to put content center stage. Elegant controls overlaid on the video until you mouse away (even the titlebar hides.)
Quicktime X lets you trim and share video using a visual timeline that makes it easy to select the part of the video you want. The edited clip can then be directly shared with YouTube, MobileMe, or iTunes.
