You confirm a 2D fisheye 180 video looks like a 2D VR180 video without distorsion, I don't need to convert fisheye to equirectangular format. Edit: So this got me on the right track, just using fisheye equidistant setting at 180 degrees with the panoramic camera instead of equirectangular. However, the image is not properly mapped onto the 3d object. I want to create a music video (which would have to be a single file) that is a compilation of multiple different 180 degree FOV VR videos, some of which are fisheye and some of which are equirectangular (thanks for telling me that term lol), so I'd need to convert all to the same type and compile them in a video editor. The only thing I'm still working to fix is a sort of pointiness at 12:00 and 6:00 when viewing in the HMD that other videos appear to fix by clipping off the edges of the oval shape, so we'll see output the VR360 footage into a equirectangular format crop the footage (i.
