Split Screen Vr Videos

Picture of Split Screen Vr Videos

YouTube is home to several zillion videos, but until recently, only Android users could take advantage of Cardboard mode -- a split-screen view designed for use with Google Cardboard and other VR headsets. That changed today with the release of YouTube 11.18 for iOS, which adds support for Google Cardboard. Now anything on YouTube can be viewed in VR mode -- even if it's not a VR or 360 video.

This bears a bit of explanation, starting with how you actually activate the setting:Step 1: Open the YouTube app and start playing any video. (Might I recommend something from CNET, or perhaps this episode of "Comedians in Cars Getting Coffee"?)Enlarge ImageTap the three-dot More icon to access Cardboard mode, unless there's already a Cardboard icon showing, in which case tap that. Screenshot by Rick Broida/CNET Step 2: Tap the three-dot "More" icon in the upper-right corner of the screen.

Step 3: Tap Cardboard, then insert your phone into your VR headset.Presto! Assuming it's an ordinary video, Cardboard mode effectively gives you the equivalent of movie-theater viewing.However, if you head to YouTube's 360 Videos channel, you'll find a huge collection of clips that really take advantage of Cardboard mode. That's because they were shot in 360 degrees, which is where the whole VR thing really starts to shine.

In fact, these videos are so VR-ready they have a Cardboard icon right on the main screen; no need to venture into the More menu. This is just the latest step in Google's increased support for iPhone VR.

Back in March, the company introduced a Cardboard-oriented SDK designed to make it easier for software developers to integrate 360-degree video.Meanwhile, Google's I/O conference kicks off Wednesday, and if the scheduled VR at Google session is any indication, there's more VR news to come. (My prediction: "Google Cardboard" gives way to a bigger, broader "Google VR" branding.) Share your voice Tags iPhone Update Mobile Google

The key reason of contemporary laptop display savers is amusement and occasionally even, security. Having said that, they had been at first created to avert phosphor burn-in on plasma laptop screens also as CRT gadgets. Screen savers aided to prevent these detrimental results by quickly altering the pictures when the pc wasn't getting used.



Let me inform you of the brain maximizing approach I'd stumbled on immediately after loading an exceptionally substantial quantity of visuals into My Pictures file, which was mechanically hooked, most likely like your computer system set up, to my monitor saver application. Immediately after sitting and looking at it at some point, I observed how it spurred on my mind and amplified my spatial reasoning ahead of creating periods. It definitely aided and that i was amazed.

5m answer viewsMost modern VR HMD's are stereoscopic 3D.  Most stereoscopic methods present two offset images separately to the left and right eye of the viewer. These two-dimensional images are then combined in the brain to give the perception of 3D depth.What you game play video you watching is a stereoscopic [split screens] Side-By-Side (aka SBS video) which is often recorded from VR.For stereo SBS video, they need to put two of those equi-rectangular frames into one video frame and then show just one to each eye.

They can put the two sets of frame next to each other, Side-By-Side (SBS), or on top of each other, Over-Under (OU). Two Eyes = Three Dimensions (3D)!image source: "What is Stereo Vision? Stereoptic? Stereopsis? Stereoscopic Vision? Depth Perception? Lazy Eye? Strabismus? Seeing Avatar 3D movie" Each eye captures its own view and the two separate images are sent on to the brain for processing. When the two images arrive simultaneously in the back of the brain, they are united into one picture.

The mind combines the two images by matching up the similarities and adding in the small differences. The small differences between the two images add up to a big difference in the final picture! The combined image is more than the sum of its parts. It is a three-dimensional stereo picture.Every video player app I've seen for Cardboard allows you to select which method to use to show the video.There is also some non-360 content SBS available on YouTube.

As you mentioned, like split screen gameplay VR videos. Lot of them are recorded gameplay from VR games, but the recorded video is just SBS video, not VR. Additionally, this is content that phones without gyroscopes (unfortunately still common) can view.I hope now you an get better Idea about what is this video is and why it is so.John L.

Answered 96w ago · Author has 2.2k answers and 24.8m answer viewsHarshal B Kolambe has the best explanation, but I'm not sure the particular tree stands out from the forest in it. The video looks like this because that's how it was rendered for consumption in a 3D headset, and they want people with 3D displays to be able to see the 3D rendering, even if it looks funny in 2D.Every frame of 3D video - what people are calling VR video here - has the same scene rendered from two slightly different positions.

3D display devices such as VR goggles need to get these two different images somehow. Ideally, the 3D video should be encoded in a way which can be passed through normal videos, so it can reuse youtube and other video channels. Two common encodings for this are side-by-side (SBS) and over-under (OU).Suppose you've got a 1920 x 1080 video stream, and you want to squeeze both the left and right images into each frame.

If you shove SBS video into that stream, then you've really got two 960 x 1080 images, one for the left eye and one for the right eye.If you shove OU video into the stream, you keep the horizontal resolution of 1920, but only get 540 pixels of vertical resolution per eye.There's probably other encoding standards too, such as alternating full-resolution images at twice the refresh rate, and interlacing the two images.

SBS and OU are what I usually see on youtube, probably because they don't materially affect the HD streaming rate.That was longer than I intended, but yeah, the answer is, it looks funny so people with 3D displays can see it just like the original player did.Neressus Decimus Meridius, PC Gaming, MMORPG, ArtsAnswered 71w agoIt is just a conversion of virtual reality imaging into 2 dimensional video.

On youtube, you can only see 2D images, so they make this split screens method to facilitate the viewer who wants to see how it is like in 3D without using glasses. In order to see the stereo/3D result, you have to learn how to cross your eyes. It will create another “splinted screen” in the middle of those 2 screens.You can watch this tutorial video:Jeff Kesselman, Been developing video-game for over 25 years, have taught game development at muAnswered 96w ago · Upvoted by John L.

What you are seeing is what is called the "stereo pair", one image for each eye.

Varun Priyan, Working on AR and VRAnswered 96w ago · Author has 139 answers and 175.9k answer viewsCause everything in VR is split screen. For VR to work you need to split the image and show one image per eye. Be it a game or video. If its captured directly from the screen then you get the split image though there are options to do it in single screen while displaying it on the primary monitor and capture it from there.
