Facebook has recently made it possible to upload profile videos (instead of your basic profile photo).
With VideoStir you can now replace the background of your profile video within seconds.
Just upload your video and any background image and you are done – the background is replaced automatically and you get a mixed video (mp3) that you can upload as your new cool “Facebook Video Profile”. No need to install any app, it all happens online. Click this link to see how it’s done.
