Facebook is introducing a new, full-screen video player on Wednesday, which offers a more consistent design and experience for all types of video lengths, including short-form Reels, long-form videos and even Live content. The upgraded player, which will first launch in the U.S. and Canada, aims to streamline the experience for both watching and sharing video content. But more importantly, it will default to showing videos in vertical mode and will also allow Facebook to recommend the most relevant video to watch next, no matter what type of video that may be: long, short or live.
