I'm filming a 360 video of a group of singers in a circle, with the singing leader and the 360 camera positioned in the middle of the circle. I'm also filming a 2d video of the singing leader from the back of the room. What I'd like to do is overlay the 2d video of the leader onto the 360 video but have it always appear in the bottom right of the 360 video no matter how the YouTube viewer spins around the 360 view (like the classic picture in picture effect). I've tried the Plane to Sphere effect in Premiere but that fixes the 2d video into a set location on the 360 video; I'd like the 2d video to almost be like a logo that just stays fixed to the bottom right of the frame when viewing a 360 video on YouTube. Is this possible? Thanks for any help folks can provide.
