I have to chime in on this. I agree the video isn't the best entertaining 5 minutes of your life, if you haven't seen the 3D effect in real life. Yet it shows exactly the convergence. But you can only appreciate if you saw the translite first
Sounds weird, but it's the truth.
It is impossible to show the three dimensional depth (depth perception) in a 2D video.
It is impossible to let your brain translate the convergence/movement you see in a 2D video to the real deal.
Such a video will always be less than impressive. Bending does not over exaggerate it - it can't: if it's too much bending, the images will jump form their most left to the first right position. The real thing is always superior.
Moving the camera forward and back doesn't work either. There is nothing in that axis that can be captured by a 2D camera. It is only left and right images, that your brain uses to calculate a 3D image from (thus let you believe there actually is a 3D space) you are looking at.
I don't want to get too scientific about the issuse, but in short: the effect is only in your head
