YouTube Brings 3D to all
Now YouTube converts videos to 3D
YouTube last year allowed video creators to convert their clips to 3D. Now, they're giving ordinary viewers the chance to do so. The online video site yesterday announced that when users access certain 1080p 3D videos from the site, they'll be given a 3D option under the Quality settings pane. Upon clicking it, the video is automatically converted to 3D, which will require users to don their favorite 3D glasses to view it.
In order to get the 3D effect to work, YouTube analyzes a host of video components, including "color, spatial layout, and motion to estimate a depth map for each frame of a monoscopic video sequence." The technology also takes cues from actual 3D videos to get hints for proper depth. After all that information is cataloged, YouTube creates a depth map and finally converts the video to 3D.
