Widescreen and High Definition Videos

Hot on the heels of YouTube's upgrade to High Quality videos, the site now lets users upgrade and viewers watch widescreen videos, as well as high definition videos. The default video player is now widescreen, and any widescreen videos you upload will display at the wider aspect ratio. You can also upload videos up to 720p resolution -- that's 1280 pixels wide by 720 pixels tall. When the high definition option is available, viewers need only click the HD option to view in full high resolution.
