The monoscopic bullet time video created by the Insta360 ONE camera can easily be converted to a 3D video by showing it separately to each eye with a time offset (1 frame). Because the camera is in motion (mostly) horizontally, a time delay creates a virtual left and right eye's point of view. For example, let's say you are swinging the camera counter from right to left (as I was in this video), if you freeze time, you can assign that view to the left eye. In the next frame, the camera will have moved counter clockwise a bit (to the "right", from the point of view of the camera), which can be used as the right eye's view.
This video is presented R-L for "cross-viewing." If you cross your eyes and look at the video, you might be able to fuse and see the 3D image. Here's more information about cross-viewing (practice! It's useful if you like this stuff).
You can also download a side-by-side L-R version to view in a VR headset or on a 3D TV. Drop the file into your Samsung Gear VR (I put it in /Oculus/3D/), and it will show up in the "My Videos" section of the Gear VR's Oculus Video experience. If you have an Oculus Rift, you can put it your computer's "Videos" folder to view in the Rift's Oculus Video experience.
The cross-viewed version is roughly converged at where I'm standing (which was default behavior). I had to converge the SBS version at infinity in order for it to look right in headset.
