Josh Constine of TechCrunch discovered the feature, and Facebook confirmed the test to him, saying it only applied to organic videos uploaded to Facebook, and not to ads, or to videos uploaded to other platforms, such as YouTube.
Facebook told Constine the new feature is being tested with a “subset” of users, adding:
This is a new feature we are testing on mobile to help people find more videos they might be interested in.
Constine said the feature appears after users play videos from their News Feeds, with videos reverting from full-screen mode to thumbnail mode and the carousel appearing at the bottom of the screen. The carousel darkens when users are watching videos and brightens again when they scroll through the suggestions.
Readers: Would this feature be a useful addition to Facebook?
