Facebook Testing 4K Videos (2160P UHD-1)

After launching a host of video-centric features over the last year, Facebook is now finally testing 4K quality of videos that can be played on the platform.

According to a report in Engadget, Facebook is testing Ultra-High-Resolution video uploads that use the 2160p UHD-1 standard for both uploaders and watchers. The social network confirmed testing of 4K video with the publication.

The website also said some Facebook pages and profiles can post and watch 4K videos. To check if you're watching the highest available resolution, click on the gear icon on the video, and switch to 2160p (4K) if available.

Video hosting platform YouTube has been working with 4K video since 2010 with 4K live streaming rolling out last year.

TechCrunch notes that while the social network has support for 4K live streaming 360-degree videos, regular live streaming is capped at HD quality (720p).

On Tuesday, Facebook-owned photo sharing service Instagram announced users could now live stream with a friend. Called 'going live with a friend', the new feature can be found in version 20 of the Instagram app for Android and iOS, already live on the respective app stores. The feature will be rolling out globally in the coming weeks, Instagram said.

Detailing the new feature in a blog post, Instagram said, "Live video helps you share in an authentic way, but sometimes it can be intimidating when you're on your own. It's easy to add a guest while you're broadcasting. Simply tap the new icon on the bottom right and tap Add to invite anyone who's currently watching. Once they join, you'll see the screen split into two and your friend pop up right below you."
