Giant social network Facebook launches a new video-messaging feature which enables you to send or post a 15 second video to your friends on their birthdays. This feature is known as the 'Birthday Cam'.

The feature would also help you tap and record the message and also there are a series of birthday - themed frames to make your videos attractive and special for your friends.

This feature is only available on iOS for now and would be seen on your friend's profiles on their birthdays.
