YouTube and Daydream partner up to improve the look of VR videos
YouTube says that its ability to deliver quality VR footage depends on the speed of one's internet connection and the device employed. To make VR look realistic to mobile users, 360 degree video has to be projected onto the rectangular screen. The process employed is called equirectangular projection. But there are some issues with this. The higher quality images appear at the top and bottom of the screen, not really the spots where people look the most. So YouTube and Daydream are using a projection process called Equi-angular Cubemap (EAC) which improves the image in the center of the screen, where most people do look.
Using different forms of projection, YouTube and Daydream conducted a survey and found that EAC was more pleasing to the eye. Android users are already seeing the benefits of this. And soon, so will iOS users and those using YouTube to view VR on their desktop PC. Check out the slideshow to see why EAC provides a better VR experience for YouTube viewers.
