Video in...3D out? can you get 3D out from a video capture card?
Is it possible to get 3D output from something like a video capture cards input, streaming live? If this was possible couldn't you essentially play your PS3/XB in 3D using your computer to convert it.

Please explain.

WHOA! That would be really nice! Now that I think about it though... I don't see how that would work... Maybe someone has some experience with this?

I was trying to capture the signal but when I play it back, it's always shows just one image. Not the double image.

Did a little bit of reading and concluded that to capture the 3D image, the driver has to capture the image after the 3D vision wrapper and not before. Because this seems to be the case now.

Capturing 3D with hardware capture does work, that's the way i use to record my own videos. [url="http://www.youtube.com/user/BlackSharkfr"]http://www.youtube.com/user/BlackSharkfr[/url]
But you have to know exactly what you are doing and be very clever.
Video capture cards record at best 60fps (in fact for most of them it's only maximum 30 interlaced fps = 60 fields per second).
If you just try to record the nvidia 120Hz signal you'll just miss every other frame and only get one of the two eyes.

So if you want to record 3D you have to find a way to put both views in one single frame.
The nvidia driver is locked if it does not detect the right 3D hardware, so it does not allow hardware capture but the iz3d driver does allow it. The DDD Ignition driver also has an interlaced mode which is theoretically usable for capture but it's much much harder to achieve.

Wait... I'm not trying to record the 3D. I'm only using the capture card for a means to get the signal from the console to the computer.
Then trying to stream that video input from a capture card and turn that into 3D output in real time.

possible?

Does the 3D get processed in the GPU or is it software?

All right, 2D to 3D conversion then.
Well automatic on the fly 2D to 3D conversion is still black magic.
Every report i've read about automatic real time 2D to 3D conversion said basically the same thing : it's crap.

I've myself tested one or two conversion filters that try to do that but when i saw the results i just deleted them and forgot their names... I don't even want to try again.

2D to 3D conversion is possible but it's just like colourizing an old black and white movie : it takes a lot of human manual intervention, and a lot of time to get a conversion look right.

Is the 3D effect rendered in the NV card or is it software?

I found a few DVD decoders that work for 3D but nothing streaming:

For 2D to 3D conversion, the ones i've tried were 100% software and were graphics card independant.

I'm wondering if the ATI all-in-wonder would be better suited for something like this.

3D is basically produced by moving the "camera" between two points very quickly to produce the images we see.

This can't work for an XBOX or Playstation console because the image being sent out to the display is just that, an image. There is no way the graphics card can take that image, and move the "camera" to get the other eye's view, because it is no longer a 3D environment (like DirectX) but an image. :(

Maybe one day Microsoft or Sony will catch on and include the nVidia card and the drivers to display 3D, but this is the only way it can ever happen.

What you are talking up is bordering on impossible. You can't just hook up a PS3/360 to the PC and expect it to automagically become 3D. There are some algorithms that produce a faux-3d effect on video files but nothing I know of that could handle a live stream. So no, its not possible.

Makes sense,

What about the new game "[b]Invincible Tiger: The Legend of Han Tao[/b]" on XB/PS3 which is a true stereoscopic 3D game with the right TV and glasses.

Invincible Tiger is a NATIVE stereoscopic game. The developers added support directly into their game engine, no drivers required. That has nothing to do with 2D conversion or anything of the sort.
