How to properly watch 3D YouTube videos
Some years ago Google changed the rules to upload 3D videos to YouTube and the way they show them on a screen, from that moment YouTube treats any screen as 2d, except 3DTVs, so any other device receives a creepy anaglyph version of the video. That is a shame because 3D screens of other types are far more numerous than 3DTVs, including mobiles, monitors, and game consoles. Suddenly, all of them started receiving a low quality distorted 3D image instead of automatically enabling the native 3D screen of the device. Knowing these limitations 3D creators started uploading their videos in SBS 3D, without any 3D flag to fool YouTube into thinking those are regular 2d videos. This way any 3D screen can activate the 3D when watching these SBS videos, as almost all 3D devices support SBS and have a button to enable 3D, so the Side by Side image generates a 3D image.
YouTube is the biggest 3D content source, and every day new 3D content is uploaded
But there’s still people thinking 3D videos were deprecated from youtube. You can forget old yt3d videos. YouTube is the biggest 3D content source, and every day new 3D content is uploaded. But almost every 3D video uploaded today is uploaded as SBS with no 3d flag, to preclude YouTube from activating the creepy anaglyph mode. However, if anyone wants, 3D videos encoded with a 3D flag can still be uploaded, thus 3DTVs and VR headsets with properly players can still show the 3D image. Unfortunately, that way they’re discarding milions of users with other types of 3D screens. There’s no reason to condemn so much people to watch the anaglyph version.-
With SBS you can activate the 3D playback on almost any 3D device, including 3DTVs without internet or any YouTube App, using an attached set-top-box, game console or smartphone. If you use a 3DTV you simply have to activate the 3D button, most of 3D devices have a switch to activate the 3D, default mode being SBS images (some also support other formats, as column interlaced and above/under). Therefore, SBS is a universal way to distribute 3D content, even for pictures and videogames, also is a format supported by the new Holographic 3D screens. Your viewers can also use any smartphone attached to a Cardboard or VR headset and play SBS 3D videos directly without even needing to touch anything, just make sure you upload your SBS videos not squeezed (100% SBS or Full SBS);
Most devices will detect automatically between Full SBS and Half SBS. Some old 3DTVs will always stretch images even if in Full SBS, but there are too few devices and there are far more viewers with VR headsets. PSVR and PC VR headsets users can play 3D SBS videos without any 3D flag encoded from YouTube too.

If you use a PC with nvidia 3d vision: if you have a 3d vision ready monitor you have only one option: Use PowerDVD (PCs connected to a 3DTV doesn’t have this limitation, as previously said you only have to press the 3D button on the TV). With PowerDVD 19 (17 no longer works with YouTube, we don’t have checked with version 18) and above you can stream videos from YouTube and Vimeo. PowerDVD detects all these 3D flagged videos and plays them in your 3D monitor instead of anaglyph. For SBS videos you have to use the secondary button of your mouse above image (while playing the video) and select 3D Source Format and then Side by Side format (or one of the other 3D formats if you watch a video on that format). You can also use a VR headset instead the monitor.
There are some 3D smartphones that doesn’t have a way to play 3D videos from YouTube
(nor 3D flagged, nor SBS), ironically the old HTC Evo 3D and LG Optimus 3D can, but no one of the new 3D mobiles -except the ZTE Axon 7 Max– are able to do this simple thing, almost any new user of a brand new 3D mobile the first thing he/she tries is to watch 3D videos from YouTube, so is strange and pitty brands does not offer this obvious function. In that cases you have to use a YouTube downloader (as Arktube, NewPipe or a Telegram bot).
On the Red Hydrogen One you also have to rename downloaded video so filename ends with _2x1 for Half SBS or _fullWidth_2x1 for 100% SBS (not squeezed), so a file named Asphalt8SBS3Dgameplay.mp4 becomes Asphalt8SBS3Dgameplay_fullWidth_2x1.mp4, that way Red Player will recognize it, maybe on a future update you will not need to download or rename video, as is a feature longly requested on the H4V forum and on the Red Hydrogen feedback App. Remember you can directly upload H4V videos from RH1 to YouTube in SBS, so other 3D devices can watch a 3D version of the Holographic video.
Google introduced another stupid problem; if you’re using the Nintendo 3DS, the official Youtube App will play 3D videos in anaglyph mode instead of using the glasses-free screen from the handheld…. Yes, they suck. But if you use the Nintendo web browser to visit youtube you will play the old yt3d videos in 3D, but in a reduced quality. The browser also allows to play Youtube SBS 3D videos on your 3DS, but with better quality than videos flagged as 3D. If the 3DS is your only 3D device we recommend you to buy a 3D Smartphone. For watching 3D videos directly from YouTube App (or even websites) we recommend the ZTE Axon 7 Max.
When looking for 3D videos on YouTube remember avoiding videos that say VR trailer or even VR 3D trailer, as they’re usually fake, they only show a 2D image even with a VR headset. Try using “SBS 3D” words on your search and ocassionally “real 3d” or “stereoscopic“.
If you find a video with fake 3D give it a thumb down and write a comment on the video saying: FAKE 3D, so other users will not lose time trying to watch in 3D that video. When browsing 3D videos you can suspect from videos with bad reviews.
