VR180 promises “the world as you see it.” That is, people with normal peripheral vision can see the world in front of them and to the side, but not behind them. Google is looking at it as a way to bring practical 3D video to YouTube. The technical effort comes from Daydream, Google’s mobile VR division.
Limiting the view to a hemisphere lets a video contain denser information in the same number of bytes. It’s also a lot easier to build a camera that takes 180 degree pictures than 360 degree ones. Adobe is joining the effort, promising support from Premiere Pro in the near future.
But just what is the format? Google hasn’t put any technical details on the Web yet. There’s a website for VR180, and you can sign up for a mailing list, but at the moment it gives no clues about the specs. According to Google’s blog, the videos “look great on desktop and on mobile,” which suggest they can fall back to a flat view.
