YouTube has announced via a blog posting that it will start supporting the 1080p high definition format.

The company says if you have already uploaded videos in 1080p, they will be converted automatically in the coming days.

The highly requested feature will fully launch by the end of next week.

1080p support will now mean very clear and crisp videos that can be displayed on large wide-screen TVs. YouTube videos you watch now on your TV via your PlayStation 3 or simply TV-out (via HDMI), will now be even more clear when viewed on full-screen. We can also expect higher quality video from channel content providers such as the Discovery channel.

You can see how clear 1080p is by watching the video embedded below.
