IMO, 65mm is a bit too much separation for objects closer than 3'. It would be better for 6' or more. If you look at the interocular specs for virtually all of the 3D camcorders made between 2011-2014- not really anything made since then - virtually all of them were in the 32mm- 45mm range. Even the pro ones were generally under 64mm. If your goal is to create nagative parallax - popout - which is generally strongest at distances of 4' feet or less, I would suggest using an IA distance of 35 - 45mm. 45mm should be good for overall 3D out to 75' or so. Most of your overall 3D effect will be in that zone with negative parallax best for objects within the first few feet. Beyond 75' or so, you will need to use a greater IA distance, but be aware that when the IA distance increases, it has the effect of miniaturizing the foreground.

Don Landis, one of our regular forum members, is the go to guy when it comes to doing longer distance landscape 3D. He has developed some mathematical tables and dual camera bench systems for this. My specialty is underwater 3D video.

Thanks for the useful info Secondphase.
