TwitVid, a free app for tweeting videos.

Smartphone owners wanting to use their mobile device to post a video to go with their tweets, now have options in the form of apps.
For instance, Blackberry users now can post short videos on Twitter from their phones using an app called TwitVid which is one of several such apps that are available on the iTunes App Store for a while.
According to the New York Times, TwitVid is easy to use. After downloading the free app, users will look for the "record" function then record their video, enter their tweet and hit send. From there, the tweet will appear as usual on users' Twitter page with a link to the video which stays st0red in TwitVid servers with no limit on the length.
Anyone with a camera phone can use the service without downloading the app by simply visiting the company Web site at TwitVid.com . Once there, users will be assigned to be used to send videos as an MMS or an e-mail with the video as an attachment with the tweet in the subject line. After that, it will post just like a normal tweet.
