Yeah, It'll be tricky getting the hang of it, but it's not as hard as some may think. Just set up your stage and put reference points (golf balls, or the equivalent) in the corners of your stage. Then model out a to-scale version of it in your software with the reference points. Next, you'll go through the camera footage and move your software camera so that the reference points line up. It may be somewhat time consuming, but it's worth it.
We're also exploring other options. But so far, so good.
As for the rendering techniques, I totally agree. High quality textures, good use of ligthing, and some minor effects can do alot.
(No one's tapped into my other hint yet...)
