360 video render of media playback???

Can’t seem to find a way to render a 360 video along with a video playing in the background smoothly (media playback), whenever I do render it skips the frames of the video almost as if its playing while its rendering because it starts at frame 0 then next png sequence/frame its on frame 100+.

Any solution to do this?

Thank you

If i may ask, how are you rendering the 360 video?
