The included QuickTime Player is limited to only the most basic playback operations unless the user purchases a QuickTime Pro license key, which Apple sells for US$xx.xx Apple's "ProApplications" (e.p. Logic Studio) come with a free QuickTime Pro license. Pro keys are specific to the major version of QuickTime for which they are purchased. The Pro key unlocks additional features of the QuickTime Player application on Mac OS X or Windows (although most of these can be accessed simply by using players, video editors or miscellaneous utilities from other sources).[3] Use of the Pro key does not entail any additional downloads.

Features enabled by the Pro license include, but are not limited to:

Editing clips through the Cut, Copy and Paste functions, merging separate audio and video tracks, and freely placing the video tracks on a virtual canvas with the options of cropping and rotation.
Saving and exporting (encoding) to any of the codecs supported by QuickTime. QuickTime 7 includes presets for exporting video to a video-capable iPod, Apple TV, and the iPhone.
Saving existing QuickTime Movies (*.mov) from the web directly to a hard disk drive (HDD). (This is often, but not always, either hidden or intentionally blocked in the standard mode. A download manager can often work around this.)
