According to Meta, all new Facebook videos will soon be categorised as reels.

The social media behemoth Meta Platforms (META.O) announced on Tuesday that all newly posted videos on Facebook will soon be categorised as Reels, making it easier for users to produce visual material.
According to the parent company of Instagram, Facebook Reels will no longer be limited by duration or format and will feature all kinds of video material, including live, long, and short videos.
Videos uploaded after the change will be categorised as Reels, but previously uploaded video content will stay that way on the platform. Additionally, the Video page will now be called the Reels tab by the corporation.
Users who presently have various settings for their feed posts and reels will be invited to confirm their audience option or choose a new one as part of the change. Additionally, the upgrade will provide users with additional creative tools.
Over the next few months, Meta plans to progressively implement these modifications to profiles and sites worldwide.
