The feature, which is still being tested internally, would allow a user to upload somewhere between five to 10 seconds of video from their mobile device to the photo sharing website, the source said.
The source requested anonymity as they were not permitted to speak publicly about the feature.
While the video feature is being tested internally, it is unclear if it will launch to Instagram’s 100 million monthly active users, who collectively upload around 40 million photos per day. It’s also unclear if the app will have Instagram’s hallmark filters.
Adding video to Instagram would pit Facebook’s photo sharing application against Vine, an application acquired by Twitter in October 2012 and launched to the public in January 2013. Vine allows users to upload six seconds of video with audio, then cross-post video to Twitter, Facebook and other social networks.
User statistics for Vine have not been released to the public.
