How to Send Videos to Twitter
Around the world, more than 50 million tweets are sent out through Twitter every day (that's 600 Tweets a second). If 140 characters aren't enough to get your point across, sending videos to Twitter will help you make much more of a statement. While it may be a little tricky to figure out how to post videos directly to Twitter, a number of third-party websites make the process much easier.
Visit a Twitter video hosting site such as Twiddeo, TwitLens or TwitVid. These sites both host video files and post them directly to your Twitter account.
Log in to the site using the username and password you use to log in to Twitter. You may need to respond to a dialogue box to allow the site access to your Twitter account.
Click "Choose File" or "Browse" to locate your saved video file. At this point, you can also add a text message to accompany the video.
Click "Upload" to upload your video and post it to your Twitter account. You can now log in to Twitter to make sure the post was completed.
