peterfallow This is in an intriguing set up and will indeed provide 4K x 2 as long as you make sure you are set to 8:7 (7:8 since these camera are set up in portrait mode) and 5.7K, 60Hz. Someone stated in the comments below that resolution is 7600x3800, not sure where they came up with that. An 8:7 ratio 5.7K (5760) horizontal would give you a vertical resolution of 5040. Adding a fish-eye lens attachment to push the FOV 178 at 5760x5040 with cropping is still capable of 4096x4096 1:1 ratio, or 8192x4096 in half-equirectangular.
The problem I have with this camera setup is the 1/2” sensor and fishy claims of 10-bit, which I think can’t be done unless you apply HDR, which uses to frames halving the frame-rate. Which would be okay for minimal motion, static camera arrangement. I do like the fact they have a G-Log mode and LUTs for post work.
Keep in mind this is hemispherical stereo capture can only be done with the additional cost of the add on 177 degree fisheye attachment lens, which not only adds another piece of glass to refract, reducing sharpness (and adding its own aberations) but I have to think it also reduces the already slow lens. Probably putting in somewhere around 3.2f - 3.4f, add to this a 1/2” sensor, and noise will become a problem in medium to low light shooting. In my experience, due to the magnification in HMDs, noise, compression and weak optics reduce the quality of such high-resolution action cameras.
That being said, the immersive experience with 155-160 degrees FOV, is still pretty impressive. And might be an option to start off without adding another lens to your setup. In fact this was direction I went with the two OSMO Action 2s, which provide 4096x3072 or 8192x3072 at 60fps. Sadly I am not too happy with the bitrate and noise level at lower light levels due to its 1/2” sensor, but I run everything through TOPAZ AI which improves detail, compression blur and less noise. Too bad DJI went away from the modular design (as did Insta360), I would have loved to see this form-factor with their Action 4, which is close to a 1” sensor with the same resolution, but a true 10-bit capture at a higher data rate.
I will be adding more of my OSMO Action 2 160FOV stereo videos on my DeoVR channel (warped and lens corrected to 180 semi-equirectangular in Davinci Resolve) over the next few days as part of my “Owl Creek Forest” series. I mounted the two Action 2s on a $100 Gyro Stabilizer with a AmbiX recorded simultaneously with a Zoom H3VR attched to the bottom of the stabilizer grip with dual suspension system and neoprene baffle to reduce noise from regripping the stabilizer. Not sure if DeoVR supports spatial audio or Dolby Atmos, but they are recorded in this format and can be viewed on the Quest 2 or 3 with DXVR and Vision Pro via ‘Reality Lens’ Here is a link to folder that contains a number of these tests over the past months: https://mega.nz/folder/ZuYhULhb#PD-EXDIzy6vX0kBEURecrw
