In addition to photos, TweetDeck provides the ability to upload videos directly from TweetDeck. There’s only one catch.
One of the ways to add videos is identical to how you add pictures. Click the camera icon, choose the file, hit the button to upload.
The other feature allows you to record a video using an attached camera.
This interface has a simple record and play button. Record your video, play it back to check it. Only catch: You only get 12 seconds this way.
After you record, a Save Video button appears. Click this when you’re happy with your video and it inserts the URL to twitvid where the video gets saved. Write your tweet and hit send!
