A while ago youtube got their "3d" option added as a beta feature,
recently it got the support for interlaced screens aswell!
So if you have a 3d screen, anaglyphic glasses, or just a crosseyed look on things. you can make and watch movies on youtube in 3D :eek:
heres a short howto:
Youtube likes the mp4 H264 1280x720 format, use that for the total size,
to get youtube to view your seperate viewpoints you have to fill your frame with 2 squished 640x720 frames,
so you are gonna lose some resolution vertically but remember its still a beta,
later it might have dual video upload.
you can scale 1280x720's afterwards or render 640x720's with a pixel aspect ratio of 2, it makes your renders look funny, but that is normal.
put the left channel left, and the right channel on the right with a vid editing program like adobe premiere
once u did that you can upload it to youtube,
and when adding comments and description tags (like: animation, short, cake, lie) , add this piece of code to the tags:
yt3d:enable=true
yt3d:aspect=16:9
yt3d:swap=1 (only when having the left eye's picture left, and the right eye's picture right)
it will activate the 3d player in youtube!
if you try to setup a camera for 3d in 3d software, try to keep 6 cm of space between the cameras
(assuming you use real scale, else you have to guess what would be 6 cm)
A bigger "eye to eye" distance makes things look smaller but more "in your face", a smaller distance makes things look bigger but more flat.
Compare it to the difference of perspective between a tele lens or a fisheye
For optimum results use a 50mm FOV,
that is about the same FOV a human eye has.
To keep the camera's the same, create 1 targeted camera where your left eye would be, and instance that camera to the right eye, and group them.
that way you will always have 2 cameras with exactly the same settings.
make sure both targets are on the same spot, and lock/group them. you need to animate the target to make sure the eyes are always converging at your point of interest.
it could be that the target is where your neutral screen depth would be precieved, but i havnt tested that yet.
here is a example i just put online:
