(Modified YT Codec) Quest 3 Passthrough 3D Video Test
Unfortunately, there is still warping in the footage despite using perception 3D like 3D game footage and not the depth IR sensor next to the outer lens.
Because this is passthrough mode on the headset's regular end and is exactly what I was seeing with my own eyes, this can't be fixed unless it's a third party/externally sideloaded app I'm recording with instead. As far as I'm aware no such app exists for solely 3D footage yet and who knows If this can be fixed.
Raw Codec is also 60 FPS but YouTube will not detect 3D or frame rate beyond 30 without special mkv modifications oddly enough.
I recorded in 16:9 but it seems this feature is only supported in the 1:1 aspect ratio due to the crop leading to a weird stretch.
This one is the modified codec which should appear 3D with proper 3D settings on supported platforms.
