Thanks for the reply. I'm still having trouble I'm afraid. Here's a screen grab of the settings we've got in the Nvidia driver:

It appears from Vegas 10 to 11 the implementation of stereoscopic output changed. Whereas in 10 you would specify a 'Stereoscopic Graphics Card' on the preview device tab of the preferences menu, in 11 there is no such option and you have to select 'Windows Graphics Card' and set the stereoscopic options to 'left and right'. All this seems to give us is a black output. It will output other steeo modes eg anaglyph perfectly but not 3D Vision.

What version of the quadro drivers are you running?

It is correct that you have to slect "left and right" and "windows graphics card" - but that is fine and works here with my Quadro 2000D.

What I miss in your picture is below "stereo - enable" (you are right: that must be on) another option that is called "stereo - Anzeigenmodus", what you could translage with stereo - display mode. Here you have to choose "generic active stereo (with nvidia)", as you see it in the picture in that German publication:

http://www.slashcam.de/artikel/Test/Sony-Vegas-Pro-10---Multitalent-auf-Speed--Nvidia-Quadro-4000.html

That seems to be missing in your driver, since it comes between "stereo - enable" and "stereo - swap eyes" - but there is nothing. No idea why that is missing.

I have to come back to you with the information what quadro driver I run - I am not at home until the weekend.

Hi Wolfgang

The article is outlining a procedure for Vegas 10. We don't have a problem with Vegas 10 in terms of stereoscopic playback. It is Vegas 11 that doesn't work. Unfortunately without the GPU acceleration of 11 the software is pretty much unusable for us.

The option for "stereo - Anzeigenmodus" or "stereo - Display mode" does exist in our driver settings, it just lives above the "stereo - Enable" option instead of below. see: http://www.redstar3d.com/temp/settings.jpg

I would be most interested to know which version of the quadro driver you are running, and which OS and if there are any settings you have particularly enabled/disabled within Vegas 11 - GPU accelleration springs to mind.

Many thanks!
Jan.

I am running in my system both a nvidia Quadro 2000D and a nvidia Geforce GTX570 (the later for CUDA supported rendering).

I had to install FIRST the Geforce driver - at the moment it is 285.62. But there is no monitor connected to that system.

In a second step - so after the Geforce driver - I installed the Quadro 2000D driver - that is 285.58 at the moment.

Since you use a Quadro only, I would try to use the Quadro driver 285.58.

I run Win7 64 bit, so all drivers are the Win7 64 bit version here.

I see that there are new driver for BOTH the Quadro and the Geforce availabel - 295.73. But I have not tested that yet. Given that I run two cards I tend to be conservative here (never touch a running system :) - or I have a backup of the system at least with Trueimage).

Settings in nvidia system settings are:
- stereo enable: on
- strereo display mode: generic active stereo (with nvidia 3D vision)
all other settings are on global mode

Settings in Vegas Pro 11 build 595 64 bit:
- preferences/view
dynamic ram preview: 0 (since then Vegas is more stable)
GPU acceleration of video processing: off (since my i7 2600K is stronger then even the GPU acceleration of the Geforce 570 - the Quadro 2000D is even weaker)

- preview device (I use a 120 Hz 3D Asus monitor with nvidia 3D vision, connected via DVI - hdmi does not work for that hardware)
device: windows graphic card
stereoscopic 3D mode: left and right

Frankly spoken, I see no difference between Vegas Pro 10 and Vegas Pro 11. The same settings work both for 10 and 11, beside the fact that SCS had in Vegas Pro 10 the device "Stereoscopic 3D Graphic card", what was integrated by SCS with Pro 11 in "windows graphic card". Here Vegas Pro 10 works fine beside Vegas Pro 11 on the same PC.

Settings in Vegas 7 64 bit:

Actually they have released v296.10 WHQL

Yes I know - but it must not be true that the latest driver are the best choice.

Just another hint - IMPORTANT: off course, you have to run the setup for 3D from the nvidia pannel - otherwise you will have a black monitor for the 3D preview.

I have also tried to install the latest quadro driver version 295.73 - that works fine here too. After the installation of the new driver I had to run the nvida setup of the 3D function again - as said above.

The only issue I see - but that is my specific setting only with two nvidia cards - is that I am not able to install the latest driver for BOTH cards. So in my case I have installed the latest Quadro driver 295.73 only, and stay with the nvidia Geforece driver 285.62.

Hi Wolfgang!

Apologies for the delay in getting back to you, I was away last week blissfully ignorant of all Vegas related obstacles!

Many thanks for your advice, we have now solved the problem. It sounds ridiculous now but it was down to running the 'enable stereoscopic' wizard. I had assumed this was an automated way of setting the already exposed nvidia 3D parameters but it appears that it does something behind the scenes that Vegas 11 hooks into. The confusion was that Vegas 10 doesn't require this wizard to be run. Plus the way nvidia have set up the wizard makes it appear as if it's only necessary for openGL/games.

Anyway the long and the short of it is (a little embarrassingly!) that to get 3D output on a secondary display in Vegas 11 you have to run the 'enable stereoscopic 3d' wizard. For anyone having the same issue...

1 Install the driver (it works with the latest (295.73) quadro driver
2 Make your secondary display (ie projector) the only system display
3 Run wizard (it doesn't see multiple displays and will pick the primary)
4 Enable multiple displays and set primary display back to desktop

Many thanks again.
