Hi guys :)

So yeah. I was uploading a new video to the good old tube last night, and noticed there was an option to convert the video to 3d. Looking at it today, it seems to work pretty flawlessly.

So, my question is, how does it work? Seems pretty amazing that YT can convert any video you upload to 3d.

Thanks guys :)

To give you more dimension on 3D, here’s some background how the conversion technology works at YouTube. Since last September we’ve been constantly improving the underlying technology, which now uses several techniques:
We use a combination of video characteristics such as color, spatial layout and motion to estimate a depth map for each frame of a monoscopic video sequence
We use machine learning from the growing number of true 3D videos on YouTube to learn video depth characteristics and apply them in depth estimation
The generated depth map and the original monoscopic frame create a stereo 3D left-right pair, that a stereo display system needs to display a video as 3D

3d conversion like this annoys me off as the results are rubbish compared to proper 3d and mean that people make poor 3d films. Ignore it cos it won't work properly
 
Youtube's native 3D support is pretty poor. I am trying to upload a 3D gaming video, and it was recorded in 3840x1080 resolution (as it was side by side 1080p). Youtube only supports half res 3d, so you have to fit two side by side pictures in a single 1920 x 1080 frame. After converting my original recording and uploading it, the 2D video is fine but the 3D video is completely the wrong aspect ratio (it seems to be squashed pretty horrendously). I still haven't found a fix for it, even forcing aspect ratios doesn't work.
