Apple Insider has unearthed proof that YouTube uploading will be built into the upcoming version of QuickTime that ships with OS X 10.6.
According to beta testers, several video-sharing options will be baked into the latest release of Apple's QuickTime media playback and editing software, including the capability to directly upload to YouTube. With the new QuickTime, you will be able to convert and upload any supported video file type to the online video service and all you will need is to be a registered YouTube user. You also will be able to seamlessly upload supported video to the MobileMe Gallery.
In addition to these new sharing options, iTunes also will offer ways to convert and export your video files to work on your iPod, iPhone, or Apple TV. All of these options will be available to you from the same convenient location and will automatically be imported to iTunes before being synced to your supported devices.
With this latest discovery, Apple will effectively offer built-in support for YouTube across all of its main products. Both the iPhone and Apple TV already offer YouTube support, along with some of Apple's other software including recent releases of iMovie. With the addition of direct uploads through QuickTime, Apple is providing support for desktop and laptop Macs.
