So far, my unqualified opinion is no.
I tested several video processors that allow the input of 3d refresh rates. I also tested this with 3d generated content at 50hz/60hz (25/60 per eye) on vps that only allow standard refresh rates.
The problem with 3d when run through a video processor is that the left eye and right eye information is switched every few seconds - the frame "1" left eye and frame "2" right eye will be switched every few seconds to: Frame "1" rigth eye and frame "2" left eye.
That will force you to switch polarity of your glasses every few seconds (time is depending on the difference between input and output refresh rate behind the comma between 3d source and edge blender or other vps).
The reason might be that some vps do not process all frames, but I guess there is most of the time a different reason. As the refresh rate probably differs on certain 3d sources on three digits behind the comma (96,02hz). The vps will have the same refreshrate before the comma (96,04) - but probably a different rate than the 3d source behind the comma. So I guess a vp that can handle 3d, must have a refresh lock function? Are any edge blenders, geometry- and pip videoprocessors known to have this?
