When you first launch iTunes 11, it's going to feel awfully different from the iTunes you've grown accustomed to. That's because it is awfully different, from many of the user interface choices right down to the brand new icon, which now even more strongly resembles that of the Mac App Store. The latest iTunes 11 promises a simpler interface for interacting with your media library and iOS devices. But before you can sync music and movies to iPad, iPhone, iPod Touch, you need to add your music, video, and other items to create your iTunes library.
Do either of the following to transfer videos to your iTunes 11 library:
Drag a file or folder from the desktop to the iTunes window. If you add a folder, all the files it contains are added to your library.
In iTunes, choose File > Add to Library, locate a file or folder, and click Open.
Download 1080p movies and TV shows to iTunes 11 from iTunes Store
The iTunes 11 now supports up to 1080p full HD video contents. You can add HD movies to iTunes 11 by purchasing them from the iTunes Store or by downloading them from the Internet. Video purchases from the iTunes Store are delivered SD and HD. HD content is offered in either 720p or 1080p. iTunes 11 by default is set to purchase, download, and playback HD content in 720p. You must change your local preference setting if you prefer to download, purchase, and playback HD content in 1080p:
1. From the iTunes menu, choose iTunes > Preferences > Store (for PC, choose Edit > Preferences > Store).
2. Next to "When downloading High Definition videos, prefer:" set your preference to 1080p. Click OK.
Depending on your computer's hardware configurations, you may be unable to purchase, rent, or playback content in 1080p though.
Transfer 1080p videos/shootings to iTunes 11
You can transfer QuickTime, H.264 and MPEG-4 movies (files that end in .mov, .m4v, or .mp4) to iTunes and use them in a video-enabled iPad or iPhone and with Apple TV. Just drag and drop the HD videos to iTunes. But not all kinds of music and video are compatible with iTunes 11 – videos in MKV/WMV/MPG/MTS formats will not import to the software, so you may need to convert some videos before you can add them to iTunes library.
