Youtube 3D, its super simple!!

[Rachel vd M]

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

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:

Never knew about this, kinda cool! Makes me wish I had 3d glasses .

anyone looking for a new screen should consider the zalman trimon,
its a 22 inch monitor with a polarised screen, and its price is fairly low compared to other tft screens of the same size.

though dont expect it to be a photographicly 100% clean and error free screen, theres minor light leakage and it has a mirror like finish on the screen.
still, it gets picked up by youtube3d and games are great to play on it! (though you'll need a(ny) nvidia card to power the 3d of the monitor)

I recently taught myself how to view crosseye 3D. Before then, I used parallel viewing.
Alot easier to do once you can do it.

Nice work

While on holiday in Ibiza, I took some cross eye 3D shots.

YouTube is down for maintenance and will be back shortly.

i hope others here will come with their 3d tests

hm nice... where can i get some 3d glasses...

[Rachel vd M]

some shops sell them,
ofc ebay does aswell.

just google it a bit

you could always make your own from filters or candy wrappers

I could only view pararell, and then I taught myself how to view Cross eye in about 15 minutes. You have to train your eyes to look at your finger, get the focussing right, and then move the finger away while still holding that focus.

The plusses of cross eye viewing is, you can view larger 3D pictures/films without as much strain.

The negative I find of cross eye viewing is, instead of pararell, where the image is going into the screen, with cross eye, its coming out, and theres not as much depth this way, but its easier to see.
