YouTube will now automatically convert standard flat 2D videos into simulated stereoscopic movies for 3D viewing.
Last year YouTube offered tools to convert videos into 3D with a click, and since then users have “converted hundreds of thousands of videos to 3D,” the site says. Now its expanding the beta test by adding automatic 3D conversion for short-form videos uploaded in 1080p.
Users can select “3D viewing” in the Quality settings on the YouTube player, don 3D glasses, “and see YouTube in another dimension.”
For the conversions, YouTube adds it looks at video characteristics such as color, spatial layout and motion to estimate a depth map for each frame of a monoscopic video sequence. Also, machine learning from the “true 3D” videos on YouTube understands video depth characteristics, and applies them in depth estimations. The generated depth map and the original monoscopic frame create a stereo 3D left-right pair, which a stereo display system needs to display a video as 3D. “With this broader knowledge of 3D conversion, we then apply cloud computing scalability to make conversion possible.”
