That makes much more sense. Apple shouldn't be in the business of making cameras. Its only the final edit that would need to be in their proprietary format. I wonder if they can do some post processing to fix the iPhone 15 pro's interaxial. I do enjoy the home made 3d videos on my Quest 2 but mostly the 180 and 360 degree 3d videos which there aren't many of. Having 3d capability on so many phones should increase the amount of 3d home vidoes to watch immensely. Unfortunately, its not going to be 180 or 360 degree videos which are so immersive.

Interaxial is the distance between the two camera lenses. The iPhone 15 Pro uses its standard and wide angle lenses to capture 3D "spatial" video. These lenses have different field of views, which would create two mismatched images, and are fixed at only 20mm apart. You can't move the lenses to be wider apart because they are built into the phone without a sliding mechanism. The average human interpupillary distance is 63mm, so 3D video from the iPhone is going to look roughly 3x flatter than what you see in real life, unless you are shooting small objects up close and assuming they are somehow able to correct for differences in FOV.
So really, this phone is not and can never be suitable for traditional stereoscopic 3D capture. It must be doing something completely different with it's Lidar depth sensor to create "spatial" video that will work in VR but not on a standard 3D display. I suspect that you will have to sort of circle around the subject as you record them, but I don't know. My understanding is that the phones do not even have this update yet. https://360rumors.com/iphone-15-pro-spatial/ So Monarch may not even be shot with a traditional twin-lens 3D or VR rig, but just a single camera + some Lidar sensors. They haven't seen fit to provide us with details yet. Last edited by BleedOrange11; 10-17-2023 at 09:55 PM. |

A little more information, regarding the iPhone's spatial video, in the comments of this article from someone who seems to know what he is talking about.
https://www.roadtovr.com/apple-iphon...3d-vision-pro/ Sounds like the iPhone will capture a 2D image with one lens and Lidar depth sensor data with the other lens. Then on playback, AI software constructs a depth map with the Lidar data and sort of wraps the 2D image on top of the depth map, like a stereoscopic conversion. The improvement over stereoscopic capture here is that it creates a, sort of, 180-degree hologram with exact true-to-life dimensions where you can get up and move to a different viewpoint to look around the sides of the subjects. The downside is that it only captures one image, so the further you move from the center to look around the sides of subjects, the more the image is going to start breaking down with artifacts. So it's more like a 3D conversion, but provided true measurements for the depth map. I expect some wonky artifacts inferior to well-shot native stereoscopic 3D, but it will probably be pretty fun, especially from the original centered position. Regarding Monarch, I think wearing a VR headset has the potential to widen the field of view, enlarge the image, and lessen the negative impact of frame violations. So potentially filmmakers could be much more aggressive with pop-outs and send objects whizzing by your head without the image breaking down or getting too uncomfortable when the objects are close to you. So we will see if they are really trying to create a new form of immersive entertainment or if the show is just another 3D conversion, shot to work equally well in both 2D and spatial 3D.

I'm sure that Monarch will be a great content.
Nonetheless... yes, we're still unsure if it will be a stereoscopic movie (with wider cameras, so to give the audience the possibility to look "a bit" around, like in a stereoscopic VR180) or they will use depth sensors to generate some side details (evident artefacts, even if AGI technologies will improve). The REAL PROBLEM is that RealD3D (Cameron's Avatar) and stereoscopic VR180/360 have NO PARALLAX and INDUCE NAUSEA. The first is ZERO degrees of freedom, the second is a 3 DoF format. But we humans see the world in SIX degrees of freedom. If at the theatre (or in the headset) we translate the head horizontally, vertically or we get closer/more distant, our brain WANTS to see what is behind/around the objects. If in an headset I "get closer" within a VR360 video the worlds moves away. I do not get really closer. And I get discomfort, nausea in some minutes. Today the only real 6DoF format is V-Nova PresenZ, that renders at Hollywood-grade quality a volume of space, and then efficiently compresses it (as a cube meter of "infinite" points of view you may imagine would occupy gigabytes per frame). I immediately and honestly admit that I'm part of this (wonderful and passionate) venture that I believe is the most pivotal innovation in movie history, following sound, because really allows the audience to "step in" and live into a movie. You could even circle around Po in Kung Fu Panda, as rendered in Maya/Arnold + the PresenZ plugin. Or get closer/around/by side of Tom Cruise or Lady Gaga, if volu-capped (a technique that is more and more commonly used in major movies, like Matrix or Star Wars). PresenZ format is already available for a demo view in SteamVR (a simple tech demo named ConstructVR), and we've started the production of the first V-Nova Studios Originals. More important, major Hollywood Studios like DreamWorks have already shown V-Nova PresenZ converted clips at the last Siggraph in LA (How To Train Your Dragon, Abominable... they're impressive!). Next Monday I'll be in LA at the ITTV conference to explain and demo the format. Should you be around... dm me! Last edited by gmeardi; 10-26-2023 at 12:20 PM. |

Monarch will not be in 3D.

Its not a false rumor, it showed up with a 3D option on the beta version for apple tv device. It sounds like it is definitely post converted and the guy(s) you quoted was not informed about it.
