Fusion at the moment does not have tools for 360 video. But, Domemaster Fusion Macros from Andrew Hazelden has some macros for working with 360 content.

I haven't used them yet. Right now i'm working on a panoramic 360 instead of full spherical 360 videos. I think the macros that Andrew has will do what you need.
