It's really just their app with this cover.
Yes. You need the app to properly format the VR180 3D to the flat screen and display in 3D at 5.7K or at least the pixel density of a 4K screen which I believe is still the highest resolution on a smart phone.
viewing these square images on a iPhone would look terrible anyway, same as a flat 3D screen, you really need a VR headset.
NO NO. The images is corrected for the flat screen. It's just that you have to use the app. Unfortunately, the app can only work with the way the EVO formats their video. If you look at the insta format from the camera each video is two insv files that the app creates a SBS VR180 3D MP4 file. This can be displayed directly in an HMD such as the Oculus GO, or you can use the app with the attached glass screen, select that in the app and the video is corrected for flat screen 3D viewing, glasses free. I haven't seen it yet so not sure how it will look in quality. I did buy a $20 clip on a couple years ago that did something similar for displaying 3D image of an MTS 3D file and it worked about as well as the glasses free screen on the TD10.
This system will not work with other VR180 3D cameras because they format the files differently than the insta camera the app just won't recognize the files. ( I'm guessing here because I obviously haven't tested this. )
And the 5.7K resolution that a lot of these 180 cameras are boasting these days aren't really 5.7K, that's actually combined resolution for both views. It's only half that per eye. That's like saying my 4K rig is 8K because it's 2x 3840x2160. You have to look at what each lens is producing.
No, not in all cases. The elements are 5.7K for each of two lenses in the 360° configuration. In the VR180 3D configuration the VuzeXR is indeed 5.7K per lens as the camera element doesn't change. So by your math then the Vuze XR shold be claiming 11.4K divided by 2.
Now with the older Vuze+ VR360 3D it has 8 cameras, each is a 2K per lens but the stitched and over under 3D composite is sold as a 4K VR360 3D camera.
The Insta360 One X 2D VR360 camera is the same, each half of the sphere is shot with a 5.7K camera.
On all cases the main shortfall is the HMD, Here the manufacturers do fool with the math and often quote 2 times the resolution for each eye. Then claim the HMD resolution is higher than what it really is. There is a movement in the industry now to stop using resolution and spec as PPI or Pixels per inch. But this is still not telling. A better way is to describe the HMD as a % of retina pixel density which is about 300 microradians. This means that a panel per eye must have a pixel density of about 2500 PPI. Most state of the art HMD's are only 10% of that so we have a long way to go. Part of the problem is we are viewing the panels at very close range so the diameter of the pixel has to be about 10 times what Apple claimed is a retina display which is measured at 10 inches, not 1-2 inches.
