Video on Instagram, with filters

It wasn't really the surprise that Facebook had been hoping for, after TechCrunch had speculated that today's announcement would involve Instagram and video, and be a competitor to Twitter's Vine. So what does Instagram's video-clip sharing feature have to offer? Well, first and foremost there are filters. Thirteen of them to be precise. How could there not be?

Then users can choose the length of their videos, anywhere between three and 15 seconds.

Clips can be stitched together to form a collage.

And unlike Vine, videos won't loop.

Finally, if you're using the service on an iOS device, you can deploy the Cinema Stabilsation function, to help reduce camera-shake.

My guess is that it won't tempt people to Instagram who weren't already there, but it might well eat into Vine's market of existing Instagram users.
