While there are a number of unofficial clients for social video site Vimeo in the Marketplace, many of us have been waiting for an official client. The wait is now over, and you can download the application now. While the application does support HD video upload, because of the silo nature of Windows Phone you cannot upload existing HD videos on your phone, only those captured in the Vimeo application.

From the features list:

• Watch and manage all your existing Vimeo videos
• Watch videos from your Vimeo inbox, Watch Later queue, or videos you have liked
• Easily like, comment on, and add videos to your Watch Later queue
• Discover new and fascinating featured videos
• Quickly search for videos on Vimeo
• Easily upload your footage in HD
• Pause and resume uploads
• Replace existing videos
• Edit titles, descriptions, tags, privacy settings, and credits
• Share via Facebook, Twitter, email, or SMS
• Add videos to your Groups, Channels, and Albums
• Get stats on plays, likes, and comments

The main focus inside the application is consuming content from Vimeo. Logging on to your Vimeo account you'll have quick access to your own videos, and the playlists of videos that you have marked up as "liked" as well as those you have decided to watch later. You also have the ability to explore the categories around Vimeo - arguably the closest competitor to YouTube in the minds of many, although there is a far stronger community of indie film-makers on Vimeo than YouTube.
