How can I convert the video frames into a 3D stage?

[GTFoxN6Y]

I started making the Xross Fighters: Ultimate Versus demo for Christmas and I think I could make my first 3D Stage for myself.

I got the frames from the video, but can you teach me how to I convert the video frames into a 3D stage for my screen pack demo,please?

 

Stage demonstration:

Stage name: Neon Tokyo

 

I wanted the stage look like this:

 

PS: If possible, teach me how to make a Zoomdelta code For the Stage.

 

THANKS!
