Get two video camcorders. Build a bracket or device that will hold each camera so the two lenses are about 3 inches apart. You can accentuate the 3D effects when you move them farther apart up to about 8 inches. But start with three inches apart.
Using the new double camera try filming something perhaps a person or thing coming at you. Be careful, damnit.
Start a new project in your NLE. Put one video on a track over the other so you can see both. Line them up. On the left camera, overlay the track with red. On the right overlay the tack with blue. When you play them, you should see the person coming at you like double vision. the two colors will be apart with purple look.
Render and export the video. Scavange or make some 3D glasses. Here’s one I like, but you can do better than this.
Watch your 3D video. If it doesn’t work you will have to play with the controls in your NLE. You must be able to put one video on top of the other so you’re seeing both at the same time. You can try making the color overlaysighter or darker.
Post your 3D video on YouTube and make a comment here. I’ll add your video.
