3D filter or trick to simulate 3D glasses

Hello...I filmed a show that has a 5 minute 3D section where the audience wears 3D glasses. I don't have to use this section if I don't want, but I'm wondering if anyone knows of a way (trick, filter or something) that I can make this segment look like it does through the 3D glasses. Thanks!

This should be pretty easy. Put the video clip on two tracks in sync and set the upper track to 50% opacity. Use the B&W effect to reduce them almost to pure black & white. Use the color correction tool to change one track to reddish and the other track to cyanish. Use track motion to move one clip a few pixels to the left and the other clip a few pixels to the right.

It won't be perfect because you'll just have two slightly offset identical images on the screen. Any astute observers will probably notice that there isn't any difference between them. However, if there's lots of motion and action it may be convincing enough. Perhaps you can keyframe the track motion to constantly vary the offset between the two images.

I saw an interesting "On the fly, cheap and dirty" version of 3d not too long ago. Still needed the red and green glasses, but nothing else. It was not TRUE 3d, but it did offer SOME depth.

The user shot with only one camcorder. He then put that on two timelines and synced them so that they played in perfect match.

On one line he applied a monochrom filter, and then somehow changed it to an odd blue green. This one he said he shifted one pixel down and three to the left.

I never got all the details, but he made one or the other partially transparent, I expect it was the monochrome one.

So, when they played, you got the effect of a slightly odd, blurry picture with a bit of a blue-green fringe on it. Once you put on the glasses, you got the artificial, and admitedly very limited 3d effect.

If you could get two camcorders shooting EXACTLY the same scene from the same tripod sitting about 1 foot apart (side to side), you might get more depth.

Not very good, but interesting.
