lighting in motion tracking

Does anyone know of any good lighting tips or tutorials for motion tracking concerning shadows in blender internal and is it possible to use cycles instead because I’d rather use that instead?

I don’t understand your question. Motion tracking has nothing to do with the renderer you choose.

Sounds like the OP is wanting to know how best to integrate CG elements into motion-tracked live footage. Fair question. The new BF DVD will fit the bill nicely, and Sebastien König has some ideas embedded in his tracking tutes on Blender Cookie. I haven’t touched cycles much yet myself - only used BI for compositing. Depending on what you’re doing, it can still give pretty convincing results.

@ Hammers: Thanks for the directions I’ll go over and check it out.
