Facebook's Instagram is officially launching its answer to the hit short video app TikTok — Instagram Reels.

The new Instagram feature will let users record and edit 15-second videos with audio, and will let users add visual effects. Users will be able to share Reels with followers in Instagram in a dedicated section called Reels in Explore, or in the Story feature where posts disappear after 24 hours.

The Reels option will be available in the Instagram app. The company has been testing Reels in Brazil since November and in France, Germany and India since earlier this summer.

Facebook has a long tradition of cloning competitive services. The Instagram "Story" feature, which lets people share photos and videos that expire in 24 hours, is similar to Snapchat. Facebook CEO Mark Zuckerberg faced tough questioning about the company's habit of copying rivals before a congressional hearing on July 29.

Facebook earlier launched a TikTok knockoff called Lasso in 2018, but closed that down in July. It also tried services similar to Snapchat called Slingshot and Poke before Instagram Stories caught on. But those were separate apps — it might have more success with a feature built into Instagram.

In fact, copying Snapchat's features was successful for Instagram in part because Snapchat was difficult to figure out for new users. They were already comfortable with Instagram. But TikTok is very easy to use -- easier than Instagram -- and part of its appeal is that you're able to sit back and scroll endlessly with just swipes, without the need to follow anyone or post anything.

For Reels to succeed, Facebook will have to lure video creators away from TikTok. This might be easier to do with Reels since many creators are already on Instagram. In response to published reports that Instagram is paying TikTok influencers to join Reels, Instagram said in a statement that the company "have a long history of reaching out to emerging creators and working to break new stars on Instagram."

"As with previous products, we remain committed to investing in both our creators and their overall experience, and in certain cases, we may help cover production costs for their creative ideas," the company said.

TikTok, in turn, launched a $200 million "creator fund" in July that it says will grow to over $1 billion in the U.S. in the next three years and more than double that globally, to pay video creators for their material.

TikTok, however, is under fire, possibly opening an opportunity for Facebook.

Microsoft is in talks to buy part of TikTok in what would be a forced sale, following threats from President Donald Trump to ban the Chinese-owned video app, which claims 100 million U.S. users and hundreds of millions globally.

Since early July, TikTok users have been posting videos urging viewers to follow them to other platforms like Instagram, reflecting the threat of a TikTok ban. Mary Keane-Dawson, Group CEO at influencer marketing agency Takumi, said the influencers she works with have been sad, angry and upset about the threat of a ban. Still, they're "pragmatic," she said, and the smart ones were already active on TikTok, Instagram and YouTube.

Reels is debuting in over 50 countries, including the U.S., the U.K., Japan, Australia and others, as well as officially launching in the test countries — Brazil, France, Germany and India.

Instagram has more than a billion users worldwide. TikTok says it has 100 million users in the U.S. and hundreds of millions globally.
