Instagram users uploaded a whopping 5 million clips in the first 24 hours after Facebook added video to the popular photo-sharing platform, CNET reports. This is a good sign for Facebook, as the social network hopes to compete directly with Twitter’s Vine. According to CNET, Instagram users were uploading as many as 40 hours of video per minute at one point within the first 24 hours.

Instagram’s “video mode” lets users record up to 15 seconds of video, while Vine only gives users six seconds. According to The Washington Post’s Hayley Tsukayama, creating videos with Instagram is similar to making videos on Vine. Users tap their phone to begin and end their recording session. Unlike Vine, however, Instagram users have a number of editing features available to them, including the ability to delete sections of their videos and the ability to add unique filters like the ones that can already be added to photos.

Several notable celebrities have shown a liking to Instagram. Canadian pop star Justin Bieber posted a 15-second video clip of himself giggling and muttering semi-coherently over the weekend. In fact, Bieber’s clip was so popular that it became the first Instagram video to receive more than one million “likes.”

Miami Heat star Lebron James also enjoyed Instagram’s new video feature by posting a video clip of himself celebrating the fact that he just led his team to a second NBA championship. “Man, I don’t know what to say. I’m a champion — two times! Two rings! That sh*t stink, don’t it?” King James said from his couch.

The Post’s Tsukayama goes on to point that the 15-second video features could attract companies attempting to drive their brand via Instagram, noting that Lululemon is already using Instagram video to advertise its yoga gear.

Nate Elliott, an analyst at Forrester Research, told The Huffington Post that Facebook has borrowed ideas and improved on them from a variety of different companies. For example, Facebook added check-ins; an idea that came from Foursquare. Now, in the eyes of many users, Facebook has improved on the video sharing app offered by Vine.
