The most popular video broadcasting website which already allows users to upload true HD videos has just achieved another milestone. Google is well know for letting its employees explore their own projects to promote creativity. As a result of the same, one of its employee, YouTube Pete (His display name on support forum) has developed this cool feature in his granted project time. To upload the video, he suggests to upload the videos in crosseyed. But even if the video is in parallel mode, you can always add the tag yt3d:swap=true this will make sure that the it will work correctly. He has also given two more tags that can be used in the tags area while uploading

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

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

Also, to fix up the old videos, there is a tag that lets the uploader to set the exact cordinates for both, left and right sources. An example he gives is yt3d:left=0_0.1_0.5_0.9 and yt3d:right=0.5_0.1_1_0.9 where the numbers are of the form x_y_z representing the exact co-ordinate. Since this is his side project, he says the fixing of the bugs will take some time. For example, the above mentioned anaglyph bug makes it confusing for the uploader regarding the stacking of the left and right views. None-the-less, the viewer can watch the videos in many different modes by selecting them from the drop down menu just below the video screen.

3D video in crosseyed mode

There are many videos already on youtube that can be viewed in 3D. As shown above, you can view them in different modes. I do not have 3D glasses  right now on me. So, I just used the cross-eyed mode and viewed the video with my eyes crossed. What you need to do is this, cross your eyes (Meaning bring them towards each other) while looking at the video. During this, there will be a time when the left and right videos will co-incide. Stop at that point and try to focus on it. If you are not getting it, you can try this first by drawing two points (thick) 10 cm apart on a white sheet and try to see them as a single point in the same way as above. Then you can shift to the video. This will make the video appear 3D. But of course, this will become irritating after some time . So, the best way is to watch it using the 3D glasses and the anaglyph mode. You can buy one as the videos are going to increase anyways. Or, you can make one yourself. Its quite easy and explained on many websites. For your convinience I will be putting up the procedure here.

Material needed:

• Cardboard – For the frame
• Cello tape or glue
• Glass papers Red and blue. Also called acetate sheets usually available in the shops where you buy art supplies. or you can use transparent plastic sheets and colour on them. Make sure the plastic is sufficiently thick. As thick as 5 pages of a good book.

Stencil for the glasses

Procedure:

First cut the cardboard in the shape of the 3D glasses. I have uploaded an image that can be used as reference. The small squares need to be made hollow on which the blue and red plastic will sit.

Next cut the glass papers a little bigger that the square holes that you made. Stick the red paper on the LEFT (It must come on your left EYE) and the blue on the right. Then stick the entire frame together. Thats it you are done and ready to watch the 3D videos using the colour modes (anaglyph) from the menu. Try with different colours and choose the best one.

Note: You can also use the CD case which is essentially transparent plastic. If you can cut it into squares and fix it on the above stencils then good. Later you can colour them with permanent markers. Else, you can use the above frame that you cut as stencil and colour directly on the case itself and use it to watch the video (For the lazy people ). Anyhow, do check them out and enjoy.
