TechCrunch is reporting that Facebook is adding video capability to Instagram, which will be announced at the former's press event on June 20th. According to The Desk, the videos would last between five and 10 seconds, but there's no word on if the photo-sharing app's litany of filters would feature in the new service. Presumably the move has come in response to Vine's popularity as Facebook and Twitter square off against each other -- a fight which would make Blu-Ray vs. HD-DVD look like playground squabbling by comparison.
