2D to 3D newbie

i really hate to ask this to you guys, but for the life of me, i cant seem to find the answers online, or i'm just plain looking in the wrong spot...

Running Vegas pro 11, with 64 bit windows 7, 3D NVIDEA graphics card with 3D vision 2 shutter glasses. In vegas, i set properties to allow stereo vision, that splits the video i have in the timeline (which is only one video stream, and one audio stream) into two in my preview window. I put on the glasses and nothing. I add in the stereo adjust video FX and get nothing but two images in my preview that my glasses (which didnt click on, anyway) arent fusing.

i know theres probably a setting with the graphics card, but i cant seem to figure out what to do, and i cant seem to figure out how to get the glasses to view a single stereo image.

can anyone please help me with the settings thing here? Frustrating the hell out of me!!!!

Sorry, you are out of luck. There is NO way this can be done in Vegas.

The big movie studios can / and do convert 2D movies into 3D .. but it takes mega bucks of equipment and time.

To have a stereo image you need two *different* images. The "difference" is very slight and corresponds to what would be seen by one eyeball vs the other eyeball. When you split a 2D video into two tracks .. they are identical because each track is what was seen by the same "eyeball" (the camera's lens)

damn...really? I thought Pro 11 would allow me to do this?... i can convert it to red green....but not side by side?

This is not a Vegas issue but one of spatial information. That is, stereo is achieved by having TWO slightly different viewpoints of the same image (e.g. your two eyes) and the subsequent correlation of the image disparity. That is why people who have only one eye cannot see depth. You state that you are splitting ONE source, meaning that they are identical images and therefore have no image disparity (i.e. no way of generating 3D).

There are some machine vision techniques for deriving depth from motion, but most of these algorithms only work under certain circumstances such as when there is an extensive non-ambiguous velocity vector field. Where the information is ambiguous, human intervention is required. This clearly goes way beyond anything you would encounter in your editing endeavors.

In project properties under stereoscopic 3d mode, select side-by-side. What brighterside was trying to explain is that one can't make 3D from 2D. The 3D options within Vegas are for editing video that has been shot in 3D. Even if you split your 2D into side-by-side and stare at it cross-eyed, it isn't going to be 3D.

If you are dying to edit some 3D footage but don't have the budget for a 3D camera, there are some affordable DIY setups that produce decent results. GoPro makes a 3D rig for their cameras (of course you'll need the rig plus two GoPro cameras). There is a ton of information online. http://filmmakeriq.com/2011/10/how-to-build-a-diy-3d-camera-rig/Start here[/link] and see what fits your budget.

cool...thanks so much guys. I know about the needing of two images, i just thought that this software did something to help convert. No biggee...

Thanks everyone!

i just thought that this software did something to help convert.You can’t “convert” 2D to 3D, just like you can’t convert B&W to color. You may colorize B&W but that requires you to manually edit the image and it looks fake. You may also move objects forward and backward in 3D space by hand (though not in Vegas) and it looks just even more fake because not only are objects placed in 3D space, the objects themselves are three dimensional (for example, a person’s nose sticks out of the face, so do his lips but less so, while the eyes are behind the face and his ears even more so.

To simply convert something automatically would require additional information that is simply not there. So, you can convert color to B&W and you can convert 3D to 2D but not the other way round.

A great example of this are some of the Viewmaster slide reels that were converted to 3D (not animated, but things like scenes from a movie set) They appear to be FLAT, cardboard cutouts placed in the scene. I hate wasting my money buying such crap .. but you don't know until you view it that it wasn't shot originally in 3D.

Hi,
Interestingly, my 3D TV has an option to convert a 2d moving images (movies, broadcast, video, or whatever) into 3D. I was intrigued with this & it actually works for most contexts. About a year ago, I did some internet research on it.

I believe that there is some sort of digital image processing that determines which objects are traversing across the frame more rapidly & assumes that those objects are closer. I also believe that the process creates a second image (for the other viewing eye) with objects digitally shifted as needed to place them stereoscopically appropriate with their calculated Z-axis offset.

I think if you search, that you can find more on this.

The algorithmic digital analysis conversion I refer to is, I'm sure, much simpler than that which is used in the industry to convert cinema for release, though I wouldn't be surprised if this technique is used as a component in the overall studio workflow.

There are ways to fool the brain. One that was used by a Coca-Cola Superbowl commercial about 15-years ago required that the viewer pick up a free pair of "magic" glasses. One eye was clear and one was about one f-stop darker. You can do the same thing by popping out one lens of a pair of light sunglasses. Anytime there is horizontal motion in the image, the delay of the image through the darker lens fools the brain into seeing stereo.

OP - the Hollywood studios achieve a 3D effect by doing a temporal shift in the image for one eye. You can experiment with it by duplicating one video track and offset it by a few frames to give each eye a slightly different image.

The following info is from the same wikipedia article. See it for details & descriptions of the following software.

There's a really easy way to do it in Vegas, it's not like shooting 3D, and it doesn't work well in static imagery, but Youtube converts 2D to 3D as well, and I believe it's the same practice as this, it's not perfect but it works enough to fool the ol' noggin.

The way I do it, is I just take the 2D footage, split it onto two tracks, create a stereo paired clip, and apply some separation in one of the 3D filters in Vegas ( can't recall the name at this very moment ).

Not as good as real 3D acquisition, but it does the trick on moving content.

This may do what you are looking for, but it's Mac only.

This is not true, that's not what they do in 3D conversions.

I found an interesting article on how Hollywood converts 2D films into 3D.
