Video walkthrough

[Seth]

I am trying to make a video walkthrough of my model. My questions are..

Can i make it more frames per second, withOUT making it faster? because i dont want it to be choppy, but i dont want to zoom through the house either.

What settings should i use for best quality?

Can i make several small videos, then somehow link them together into one movie type file, with music and effects? Because if i mess something up, and have already gone almost through the whole house, i dont want to have to redo the entire thing.

Is there an easier way to go about this that i just dont know about?

PLEASE PLEASE PLEASE, help me out. THANK YOU!
