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…

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.

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.

    I found these lines on a youtube forum that might help:

    yt3d:enable=true
    Enables the view mode. (obviously you’ve already discovered this)

    yt3d:aspect=3:4
    Sets the aspect of the encoded video.

    yt3d:swap=true
    Swaps the left and right sources. You may need to add this to videos when the player with fixed anaglyph modes ships.

    yt3d:left=0_0.1_0.5_0.9 and yt3d:right=0.5_0.1_1_0.9
    These tags are very provisional and most useful for fixing up old videos. They set the source area for each eye as pairs of coordinates x1_y1_x2_y2. The scale of these coordinates is 0,0 for the the top left down to 1,1 for the bottom right.

    First, scuse for my bad english!

    I want to report a major bug of the new function “3D”, on some youtube videos!

    We start with this exemple: http://www.youtube.com/watch?v=W4IH2OS3SKY&feature=player_embedded

    If I want to see this video, on youtube site, there is no problem. I click “3D” and I choose my favorite viewing mode: magenta green, red cyan, crosseye etc. etc.
    But if I want to embed this video on my site I don’t have de 3D button to select the prefered viewing method, and the video is crosseye, by default, even I select on youtube the red/cyan mode! (My website is for anaglyphic content and is a major problem!) This happend on some 3D videos, not in all the cases!
    I see two way to solve this big problem:
    1. When I customize the embed code, would better to have the option of viewing mode (red/cyan, green magenta, crosseye etc.).
    2. The second and more complicate solution is the design of 3D button on the embeded players because this selector is show only when I watch a video on youtube site!

    I am the first that report this bug?

    Well, actually it is not a bug, but a well known lets call it a limitation… YouTube usually remembers the last choice you made watching 3D video and applies it when watching embedded 3D videos by default. I suppose that YouTube just wants the viewers to go to their website to watch the 3D content and not just to watch embedded 3D videos.

    Hello mate, how can I embed the video in 3D on my site?
    Because when I embed it I see it on “side by side” and I cannot to select the type of 3D.
    Please help me.
    Thanks a lot
