I am stuck with a strange export problem in Premiere that I haven't seen anywhere else. My 360 looks fine on the timeline and in the Media Export Preview. But when I export (direct export or Media Encoder) it comes out like it was filmed with a fish eye lens. The sequence settings are equirectangular for the projection and monoscopic, 4096 by 2048.
I am using proxies after importing ProRes files that I output from a different project with identical settings (see screenshot). I set it up like this to make playback smoother and get rid of complexity. Anybody else seen this? I include a screenshot of the distorted output. Tried exporting H265 and also Adobe's default monoscopic VR
