Facebook announced at its @Scale Conference 2016 in San Jose, Calif., Wednesday that it developed a custom-designed stabilization technology for 360-degree videos.
Other announcements by the social network at @Scale included the open-sourcing of its Zstandard compression algorithm and the deployment of its MyRocks next-generation MySQL storage engine based on RocksDB.
Facebook said in an email to SocialTimes that current video-stabilization technology is generally designed for videos with narrow frame views, such as those captured via smartphones, and for 2-D motion models, which is inadequate for 360 video, adding of its new technology:
This new approach combines 2-D and 3-D stabilization methods with a new ?deformed rotation? motion model to make shaky 360 videos incredibly smooth so that they’re easier to watch with less chance of motion sickness. It improves efficiency, with a 10 percent to 20 percent reduction in bit rate for the same video quality. And it’s fast?it can stabilize video in less than 22 milliseconds per frame, meaning that you can improve your video stability with no major wait or interruptions when you upload. In fact, videos can be stabilized using this technology in less time than it takes to play the video at normal speed.
Research scientist Johannes Kopf provided a detailed look at the development of Facebook?s news 360-degree video stabilization technology in a blog post, citing its advantages over current 2-D and 3-D models:
