Instagram is introducing a new feature called "Features" that allows for long-form, horizontal video content. Creators can now upload videos up to 90 minutes long, a significant increase from the previous 20-minute limit for Reels. This new feature is Instagram's first major entry into this format. Instagram's head, Adam Mosseri, initially opposed long-form video on the app but now sees it as essential for meeting creators' evolving needs. Features is designed to work in conjunction with existing short-form content. Creators can post Reels that link directly to their longer "Features" videos. This allows users to discover longer content through shorter promotional clips on Reels. Mosseri explained that these long-form videos will be discoverable through various means, including links on short-form content and the Explore page. They will also be integrated into Instagram TV for a bigger screen viewing experience. This move positions Instagram as a platform for all types of content, from quick "snackable" videos to more in-depth viewing. The introduction of "Features" makes Instagram resemble YouTube, a platform dominant in long-form video content. This expansion is likely motivated by the significant advertising revenue generated by long-form video on platforms like YouTube. Instagram aims to keep creators and their audiences engaged by offering a comprehensive suite of content formats.
