Today I've taken one of our shots, converted it to Iff format and put it into Autodesk Maya to match a ground plate to its perspective. It was extremely challenging as our raw footage ground wasn't entirely flat, in fact it was a slope road, and slanted sideways! I matched the ground nearest to the camera first, and extended the plane with lots of divisions so that I could move its edges and vertises to match the slope further away from the camera.
The biggest challenge was matching the slopes, it seems almost impossible to do a awesome match as perspective gets smaller towards the vanishing point, and it is impossible to zoom in nearer to see while not moving any geometry or changing perspective. Hence it was hard to align the plane to the footage.
This part of the process took the longest period of time, once it was done, I added other geometries like cubes to test out my perspective against buildings further away in the shot, it seems perfectly fitted!
Once this was set up, I can add objects into my scene and have less worry. I tried to add pavement at both sides of the road with 3d texture of fractal noise, assigned "use as background" shader to the main road so as to cast shadows. I've also lighted the scene using directional lights with raytraced shadows and afew point lights with depth matte shadows as well as area lights for bounced lightings.
I've also tried to play with something new that I wasn't taught yet, under dynamics - shatter, to create debris from geometries. This is be something I need to find out more to make it photo realistic as its another eye candy to an "Apocalypse" shot.

Thank You
