First, that's a very long shot. I'd work with just the part you want.
Second, you should stabilize the footage first then render a DI (digital intermediate) to a lossless or nearly lossless codec.
Then you try a 3D camera track. At a mid point in the shot set a ground plane and then add a plane and a camera.
Now just draw a mask line on the ground plane and apply stroke. That's about it. There are lots of tutorials but I'd look first at Adobe TV for the basics.
