True Stereoscopic 3D Trailer of Avatar is Available on YouTube 3D

May 1st, 2010 · 17 Comments · 3D Movies & Videos


We finally have a true stereo 3D trailer for the movie Avatar available, it is in German, but that should not bother you much. The trailer was made available on YouTube 3D where you can watch it, but below you can also find download links for the full quality MP4 video saved from YouTube to watch with 3D Vision Video Player or the Stereoscopic Player. The video format is Side by Side and you need to select 16:9 aspect as the video is squashed into 1080p horizontal resolution. The quality is not the best possible, but is still quite good and the 3D effect is of course better than the autoconversions to 3D we already have for some time now. Don’t forget to leave your comments below if you watch the trailer…

And thanks to weir3d, who originally uploaded the stereo 3D trailer to YouTube, now we have the source with better quality and English audio. The file below is the Avatar true stereoscopic 3D trailer with the full quality, 1080p squashed (you need to select 16:9 aspect in the player!) in a Side by Side format.

What New Features is NVIDIA Preparing for the 3D Vision Owners

January 19th, 2010 · 10 Comments · GeForce 3D Vision

You can say that in the last month Nvidia has been keeping pretty quiet regarding driver updates for its 3D Vision product line. One can say that this was due to the holidays and then the CES and this might as well be true. However it also seems that Nvidia has been working on some new and interesting features for 3D Vision that should be introduced pretty soon. So here are some bits of information on what to expect in the near future…

3d-vision-surround-avatar

3D Vision Surround. This new mode will be introduced with the release of the new GF100 “Fermi” video cards based on the latest Nvidia GPUs. This mode will allow you to use up to 3 different 3D-ready monitors or projectors as one and in stereoscopic 3D mode. The application and games support here is still a bit questionable as this will introduce much wider resolution and will need more FOV, but we’ll have to wait and see how will these possible issues be addressed. With 3D Vision Surround you should be able to use up to three 120Hz displays with Full HD resolution in 12

YouTube 3D for 3D Vision. YouTube has been working on adding stereoscopic 3D video support to their free online video service for a few months already. The required support for 3D Vision and frame sequential format was still lacking as it seems that adding it requires some new features. That is why a new version of Adobe Flash Player would most likely be required and such update is already been worked on… Nvidia has demonstrated a working beta of the YouTube 3D support during CES.

3D Gaming in a Window. Not this is very important, especially to all the people playing MMO games and willing to play them in Stereoscopic 3D. So far you could only use S3D mode not in a fullscreen mode only with Quadro and professional applications supporting Quad Buffer OpenGL. Being able to use games in S3D along with 2D applications in the same time would make it quite easier to do more wile playing on a bigger resolution screen and this is good with all these Full HD monitors coming out.

3D photo web browser plug-in. Another good thing is the option to view stereoscopic 3D photos directly from your browser of course if they are in the respective supported format. For that an additional plugin should be needed and it is supposed to be available for Internet Explorer, FireFox and Chrome.

Stay tuned for more as additional information about these upcoming 3D Vision features becomes available…

How to Upload Stereoscopic 3D Videos to YouTube

December 9th, 2009 · 4 Comments · Other S3D Tech


Some time ago YouTube has added support for uploading stereoscopic 3D movies in a side by side format (left and right frame into a single video stream next to each other) and then view them in different mode. This feature has not generated too much attention, simply because there is still not that much stereoscopic 3D content that can be freely distributed. And to tell you the truth I’ve known for this YouTube feature for quite some time, but I’ve tried it just today by uploading a clip recorded with FRAPS to test it…


youtube-s3d-video-upload


If you already have the stereoscopic 3D video clip ready you can quite easily upload it to YouTube and you just need to enter something specific in the field for tags at the end of the list of tags you’ve provided for your video. The tag you need to enter as a last one is “yt3d:enable=true” (without the quotes) as you can see in the screenshot above – have in mind that this tag needs to be at the end and not specifically to be the only one entered. And that is it your stereoscopic video is uploaded an being processed and when it is ready you should be able to view it in the available Stereoscopic 3D modes that YouTube currently supports.


youtube-s3d-video-modes


Here s a list of stereoscopic 3D modes that the YouTube player currently support with the main focus being the anaglyph modes, but there is also support for cross-eyed viewing method that does not require special hardware and there are even experimental modes for row interleaved viewing for passive polarized display users and a few others (including option to view just the left or right video frame in “plain 2D”). As you can see so far there is not way for you to directly watch the videos in stereoscopic 3D mode if you are using Nvidia’s 3D Vision setup, but do not loose your hope as there is actually a quite easy workaround. You just need to download the High-quality or High-definition version in MP4/MOV format of the YouTube video you want and then play it back through the NVIDIA 3D Vision Video Player without problems. And if you have some issues with playing back the downloaded movie you might need to first setup the codec list of the 3D Stereo Player in order to add the installed MP4/MOV splitter/decoder in your system (Settings / Decoder / MPEG4 Stream Splitter).

Have in mind that there are some possible issues when sharing Stereoscopic 3D videos through YouTube. I’m talking about the limited resolution the Stereoscopic 3D videos are being processed at and then made available for the user. And then there is the issue wit the quality as when the video gets re-encoded with a lower resolution an bitrate than the original one being used, so watching through the player or downloading it afterwards might result in not that great quality. If you want to upload 1080p stereoscopic 3D video or even a clip with 720p quality to YouTube you should forget about that with the reason being that you still get 1280 and 1920 maximum width for the re-encoded content you’ve uploaded as stereoscopic content. So for true 720p quality you’ll be uploading video with resolution of 2560×720 that will be downsized to 1920×540 (1080p HD) and 1280×360 pixels (720p HD), so you might consider recording the video in one of these two resolution, if you plan to share it exclusively through YouTube. This way you might achieve better quality when the video is being just recompressed and not resized by YouTube, but still it depends on a lot of other factors so it still might be considered to be a trial and error at first.
