This video is an example or a demonstration of the Photos App in #Windows10 showcasing capabilities of the application. However, the #PhotosApp outputs 1080p for the original 4K videos and all #360 footages are flattened to produce equirectangular output like this.
The Windows 10 Photos app is really a powerful video editing tool that can even handle some 3D images but when it comes to 360 images and videos, they all are considered to be the flat media files.
I shall post the original video once I find a proper clip joining application for Windows 10. This video was taken at the Davis Falls (Patale Chhango) in Pokhara. You can see how beautiful the place is (if you can't see, I'll post the original 360 video link here.)
