3D video and Vegas?

Just saw Friday the 13th 3 in 3D tonight at my local theater. Had the glasses and everything. I also thought this was a gimic, but it was really cool I have to say.
I'm just wondering what you have to do to make a 3D movie. When I took my glasses off it looked like there were 2 copies of the movie- one slightly up and to the left of the other. Surely there's more to making 3D than just making a copy of your footage, lowering it's opasity, and moving it up and to the left in the frame.
I'm helping some friends make a zombie movie next month and thought 3D might be an interresting marketing gimic.
Any thoughts?

Expensive.
i've done a bit of work on 3D video. You need two cameras, if possible locked with an SPG although not vital. The cameras should be about the same distance apart as your eyes. Withour special rigs zooming is a no no as they have to zoom at exactly the same rate.

One it's shot you then have to edit the two tracks excactly the same. Each video can the be projected through a spearate projector, one woth a vertical and the other with a horizontal polarizing filter. The images are put onto the screen a small distance apart and glasses with corresponding filters feed the two images into each eye.

I've also seen it done with one PD150 and a revolving mirror fed from two lenses. The mirror is synced to the video so that one field comes from one lens and the next field from the other. Pretty wierd experience pointing the camera at yourself and looking at the screen to see your hand coming out of the screen.

Lens kit was about $18K.

Okay, that does sound expensive, especially as they're shooting on 16mm and are paying for it themselves. If I ever tried it I'd do the cheapo way with my pd150 and maybe borrow a friend's pd100a or something like that. But it sounds like if you get anything off, you're pretty much screwed and all your footage would be a wash. When you're talking about the projectors and the filters, could you use digital projectors for that? Oh well, doesn't sound like it's going to happen on this project, unless you could rent one of those mirrors you were talking about.
About your experience with 3D, how did it turn out? Is it a movie you can buy or rent?
Thanks for the help.

I think there's a plug-in to photoshop if you want to play with 3D stills. You'll need the red/green glasses I think. Other than that there's the polarizing method of making 3D-video. The left eye only lets through horisontal lines and the right only the vertical, or something like that. Still you need the two cameras as farss says. Dunno much about either method though.

The 3D turned out quite well, its only brief footage shot around the Sydney Observatory. Its part of a very slick display in the observatory's 3D cinema. Mostly NASA iamges used to create 3D views of the universe. Developed by some fo the local scientists. Program appear to run off DVD but using specialised controls, you can zoom in on a planet, rotate it and move it in and out from the screen all at very high definition.

The 3D footage is only about the history of the observatory which is now a museum. Projection is done through two data projectors using polarizing filters and a special screen, I suspect that's to preserve the polarization of the light. Big advantage of this system is it preserves the color balance.

I tell you have Jupiter come out of the screen and hover over the head of the person in front is pretty freaky. If you're ever in Sydney it's worth a look, admission is only a few dollars and that's for a good cause.

Thanks for the info, y'all. farss, that does sound really cool and I'd love to check it out some time. Unfortunately, it will probably be some time as I live in the deep south in the u.s.
Always thought the 3D stuff was a gimic and didn't do anything, but it was really cool last night and I'm sure your project is something to behold.

Canon makes a nice 3D lens for about $8000.00 that fits on,the front of an
XL-1. Don't know how the editing is handled.

Look at this. They use anaglyph and a software solution to adjust the left and right perspective on a single clip. I haven't used it but it may be fun to play with. They even send the glasses. Good Luck John.

you can rent one of our 3D camera's : )
(we have several)
-- we have a smaller version also but here is some pics of one at a shoot recently ..

The idea of two cameras with your eye distance will work gor you buteveryone have different eye distance and will not work good.
The 3d perspective is based on difference of angle of image betwine two eyes.Cover one eye and notice the video the cover anothe and see the difference of angle.The images are shifting.
With two cameras you get indentical two images,but your eye are not indentical.One can see more detail that other. With all the image shifting,angle and detail difference betwine the eyes some my come with idea of 3d video.
