Export 720P Video in QuickTime

In an undisclosed and largely unnoticed update to its QuickTime video playback and conversion software, Apple has quietly added an “Export to Apple TV” feature capable of creating high-definition videos viewable on the Apple TV accessory. Export to Apple TV creates not only full DVD-quality 720 by 404 videos, but also 1280 by 720 videos that are viewable in iTunes.
