I'm guess I'm saying this:
So that's from the side, where my eyes would be in the middle of the circle. Her body is the orange line. So to get her body upright, I need to change the 'pitch' so her body moves around that circle. But when she's finally upwards, she's floating like a meter above my floor.
And like said, with that 'taste of egypt' video at 3:40, as a comparison, I don't have this problem at all.
Actually I just tried: if I go and sit myself on the floor (instead of in a chair) so I phyiscally lower my eyes about half a meter, then I actually see her walking on my floor in a normal posture. But then the dick is floating like 30-40 cm in the air. And also if she then moves closer, her body kinda 'morphs' I feel something is off.
Actually I now realize, by watching in non PT mode, that at this point the actor was also sitting on the ground (actually on a cushion/low chair it seems). So I guess that for PT to work, you need to take the same position as the actor, so you'd need to sit on the ground (or a low chair) too in this case. And then indeed she walks on my floor correctly. However like said, not sure why the dick is then floating around about 30 cm above mine.
I guess there are two things at play here:
1) My eyes need to be at the same distance from the floor as where the camera was. So if the actor in PT is sitting on a low chair, you'd need to do that too for it to look correct. For example if you stand up, the model of course will always float up in the air since the camera was way lower.
2) The distance between the actor's dick and the camera needs to be the same as the distance between my own eyes and my dick.
Point 1 I can change (by just physically moving up/down), point 2 I can't. I think that's causing the problems I'm experiencing in that part of the movie. Of course I can somewhat 'correct' for all that with the settings but it will just morph the image and will introduce new problems. I'm a tall guy, I'm now speculating that it actually might look better for a small guy.

i see what you mean
but look at the male performer position, he is almost laying on that chair
so in order to get same perspective you just gotta put yourself in the same position
sadly thats the only way it would work in this case
we could ask @George to get a higher chair perhaps, but if another user with a lower chair will watch this scene for him her leg will be under floor.
thats sadly just a camera heigh and in post we cant change that
for another thing i was talking about i made a simple video sample where you can see how the distance (ipd) between the two background images affect model position and scale as well
harigeharry So I guess that for PT to work, you need to take the same position as the actor,
exactly what i meant here
Manny_S switch to the non-pt mode to see how the dude is sitting on the chair and just sit same way and the dick will be there
It's an interesting remark about asking George to use a higher chair. I never even thought about all this stuff, I'm just that guy watching porn LOL. And i'm quite sure that's how it works most of the times and most wont even realize that their eyes need to match the camera's height. So the question then should be, what position does the average guy have when watching VR porn? I'd say he's sitting in a chair most of the times so in that case using a higher chair indeed would make sense.
In a previous post, I believe Manny commented that production is using the same camera and/or lens as earlier Simsense Media releases but I have to question this (please take no offense). With respect to scaling and perspective issues, I would assume that the lens being used is wide angle. Wouldn't a 35-50mm lens be more appropriate?
In contrast to SLR PT videos displaying models too small when further away from the camera, competitor videos have the opposite where the model becomes too large.
Could lens use (focal length) and possibly magnification be what's so different from when these AR PT videos were so great/immersive?
So I just viewed the Cherry Candle scene. Again, the image improvement is a huge step up, really love that! But the first position that the male actor takes (sitting on his lower legs) definitely will be a position most viewers won't have when watching this. So when the viewer needs to rotate the image to correct for that, it all starts to look worse. So again, please make sure that the male actor doesn't use positions like this. I think it's best to stick to only a few positions and sitting on a (normal height!) chair definitely should be the main one. I think @George shoots these, right? So please have that in mind, it would definitely improve things.
Actually I think that until we have real 6DOF available, passtrough video's should limit themselves to only 2 positions, either lying or sitting on a chair. Nobody wants to continually figure out which positions the male actor has and move themselves into uncomfortable positions. And the alternative, manipulating the image via rotation, zoom etc only makes things worse. That never should be necessary.
EDIT Actually I just came across this thread and the topic starter made that exact same suggestion (as some other great ones like not fucking back, that's really a no-go in PT indeed!) https://forum.sexlikereal.com/d/5934-lets-discuss-passthrough-not-a-yay-or-nay-thread
I think if you guys improve on that, your video's are going to be really good.
harigeharry But the first position that the male actor takes (sitting on his lower legs) definitely will be a position most viewers won't have when watching this
Hehe - this is very much on point. It is a bit comical to be in PT, not able to line things up, turn it off to check the positions and see that "Oh, yeah the stunt is on his knees on a low couch with an extra long seat and the actress is placed on a box in front of him" 
harigeharry Thanks for the feedback and new chair has been bought 
Just you have to wait a while ... 
George That's just awesome news!! Really looking forward to seeing that change, thanks again!!
I red throuht this whole tread. Passthroug will be the thing in the future and I am fan of it. I still don't understand why it is so hard to film passthrough videos correctly. I picked up the best points that seems to be problem although they should be obvious to every director.

takabom "Oh, yeah the stunt is on his knees on a low couch with an extra long seat and the actress is placed on a box in front of him"
Why isn't this still not obvious to directors? This tread people are talking about different IPD etc. nonsense. Why not use common sense instead? You have to decide which positions to use (what fits for average guy) and stick with that (Cowgirl, missionary, doggy etc). Nothing extreme only because you can and are able to do. "Booring" is good in PT. No leaning or much back and forth movement, it has to be in same plane. Be in the center of the screen. Otherwise you get scaling issues and distorsion when users try to correct image.
Deploy "porn filming chcklist". Same method as they use in aviation (flying checklists). This way you can measure and be sure of proper lighting, focus, distance, angle etc. Someone said it is just math ant that is correct. Everything should be measured and checked, no feeling or intuition. Otherwise there is possibility to screw thins up. For example you have to measure how close girl can come to kiss you (don't want crosseyed video) and what is the spot to kiss. Attach some "fake lips" and eyes to the rig and teach girls where to look and kiss properly.
Nothing is so sad as if seeing gorgeous woman in passthrough ruined by left lens out of focus or smudge in the lens (as there has been in StacyQ videos more than one year) or hot girl looking only other lens and kissing your ear or eye instead of lips.

This indeed is SUPER important for any PT director to realize. This is all about logic, about thinking this through and then make sure to have procedures in place so that everything is optimal. There's no place for 'artistic feelings' or 'intuition' here, that will only mess things up. This is just boring logic. A checklist is an awesome idea. I also really loved the laser pointer idea that someone had above, to attach a laser to the cam and make sure that the dick is always in the right place relative to the camera.
I also love the 'boring is good in PT' strain of thought. That's exactly how the PT director should think. Nothing fancy, just 2 positions for example (sitting and lying), no weird movement by the male actor (even way better, no movement at all, have him lie still like a dead body LOL) and let the actress do all the work. And actually I'm starting to agree, all this is NOT that difficult at all. In the end it's all about understanding how viewers are watching the scene, making sure that the male actor's position matches the viewer's position, that their eyes and dicks are in the same place. And then of course the regular filming techniques like lighting etc that any director should already have. This isn't rocket science.
harigeharry I said "that their eyes and dicks are in the same place" of course is not correct, should be that the camera is where the viewer's eyes are and the dicks should indeed be in the same place, but that's obvious. That's why the laser pointer on the cam is such a great idea, the type of pointer that also registers distance so that also continually can be checked. https://www.amazon.com/s?k=laser+distance+measuring+tool&crid=3R9A6TUL7D3NZ&sprefix=laster+distance%2Caps%2C281
harigeharry Those laser pointers are really accurate. I have used them at work before.
Regarding the latest Era Queen PT vid, I know we'll have to wait for the new chair But also @George please avoid male fucking back in PT, it just results in this floating dick syndrome LOL. The girl should do ALL the work in PT.
harigeharry Got it! Thanks for feedback 
been out for a few months, I cant believe how inconsistent PT continues to be, some recent scenes are completely unwatchable like the Lia Lin scene, was everybody on set sleeping, that modded canon lens obviously needs more attention when being used. Then again you have scenes like Era Queen scene that completely blew me away how sharp and crisp everything was, granted the scale was a little big, I cant tell if its was a vanilla canon VR lens or if the SLR team has been using the FMDUO camera of their own or from the VRBANGERS team. If our options are either modded canon lens with poor results trying to "achieve" better scaling but terrible focus or slightly larger scaling with near perfect sharpness then the choice is obvious, at least give us the sharpest picture possible.
