Umm...

Er...

The only thing I can think of is - ask Peter Jackson or George Lucas to help you out. This kind of photorealistic animation is an enormous project.

The room area looks like a fairly simple shape. Can you still get access to it? Does it look the same? You could maybe take some photos and put them onto a UV-mapped model, built e.g. in Wings3D.

As for the girls, you might find clothing and hair to match, and morph some faces, but they definitely will look CGI.

Poser works for Final-Fantasy style animation, where everything has a superclean CGI look.  As for making things look down and dirty, that's something the major studios are still trying to perfect. It might well be possible, with a lot of work, to get some kind of interesting fight animation. But it's unlikely to match your camcorder footage.
