VR180 Stereo video and perceived scale
dudder Hey, this is actually more important on how they shoot on set. Just avoid going that close. There is a limit on how much you can fix the doubling effect since if the subject gets too close, the left and right image differ so much the brain cant join them into coherent image.
But what you describe is actually autofocus feature, just limited to really close stuff only.
dudder When things get too close they go beyond the "near point of convergence" making you see double.
Or see one, me and this female I use date we use to be upclose cuddling and what not and we be so close are eyes would turn into one, we use to think it was weird how it did that, lol make you look like you had one eye. It's cus you looking at an object up close, the closer you get to the middle of eyes you looking at it crossed eyed.
Put two fingers up in front of your face and move it closer to the middle of your eyes touching your forehead, you'll see one fat finger. Lol
It does that in vr too, I would see viewers complain, "why I see double during close ups" I'd be there just thinking well it does that in real life" lol 
To me that double vision up close just added more realness, but only during close up kissing it was ok, during close up 69 or ass eating I'd rather have no double vision during them parts. 
Sandi_SLR Hey, this is actually more important on how they shoot on set. Just avoid going that close
Oh God please don't say that
Xzibit A
Sum 69 are way to far 
, sum are even further 
, the female will be there asking you to eat her, and I'm thinking well I would if you come closer. Lol
Xzibit b,
This how close a 69 should be 
Closer the better, imo
Even in like laying cg, she'll lean in, and say you like my tits in your face, and I'm like yeah but come closer, lol ...smother me, motorboat me with them! GET CLOSER! just don't get to close the cam accidently moves. Lol
Sandi_SLR I see what you're saying about how shifting the horizontal offset makes it similar to autofocus. I tried messing around with that and at least the close up images look better when they're maxed out at 7.5+. I'm not sure if there's a way to stitch the image back together without goofy looking scale downsides like you mentioned. At least the autofocus is going to be cool to have!

Vrsumo2017 I mean... in real life you don't even see pussy when you licking it. You see the belly maybe but you don't see pussy. One have to have eyes inside his mouth to see pussy while licking it.

So if you want to focus your eyes on close-ups it has to be further away. Which in missionary and pussy-licking or kissing is not an option, you can't reach it.
Or either its like in real life so close to your face that you can't focus on it.
Put your hand in front of your face and imagine its a girls face and try to focus on it. In real life there is no such a thing as focusing on an object that is too close! But do we complain about it? That's our physiological limitations, no way to do that and that's ok. That's how you feel that something / or someone is too close.
By the way, who's kissing with his eyes open?
metaverse You see the belly maybe
Lol, or looking up at under boobish, 
Lol, or if its non shaved you looking at hair, or if its shaved you might be looking at razor bumps

metaverse ima post this here as a suggestion since we discussing upclose oral
But I've suggested on forums before why studios don't do pov oral with the male actors during 69
It'll look like this
Or do standing pov oral like this
I think it would work but we would have to see what kinda feed back it gets from the viewers, I would do a studio just focused on upclose pov trying to get them kinda shots, 69, kissing, sucking tits, sucking ass and what not. It be sum kinda pov oral fetish I guess
And please no one say kissing pov can't be done cuz look at this shot
And heres how sucking tittys pov can be done
See how you see down dudes nose, all she had to do was stick a titty in his mouth and you got your self sum pov titty sucking.
It can be done, imo.
And tha camera that far back you really don't see guys nose down depending on how you got your tilt with the tilt option in vr players like deo.
Thought I throw this out there as a suggestion cuz there's no real pov of oral situation.
Vrsumo2017 Hey, please keep posts on topic, thanks.
So I tried adjusting the horizontal offset on a Melody Marks JAV VR scene where the scale was too small.
While it increase the scale nicely when she was close to the camera. It wreaked havoc to the background. Where the images from both eyes no longer converged properly. And gave me double vision.
I think I prefer to simply zoom in or out to fix the scale. Versus playing with the horizontal offset. Yes, zooming will introduce geometric distortion, but it’s much more watchable to me personally.
Unfortunately, I don’t really see adjusting the horizontal offset as a long term solution. 
bacula8630 Adjusting horizontal offset was only an example that mimics what the initial post is talking about.
This step is done by post production when they prepare the video you watch, so they kind a set the default value.
Ah…got it. Thanks for the info.
What about a beam splitter camera rig? It looks like that can adjust the convergence down to 0 for close up shots. That should clean up any of the double vision effect.
It's a new camera setup though so bleh... It would also have to adjust the convergence quick enough to keep up with the performers, no idea if that's possible.
