First result of the Google search is a decent tutorial for the basics and the second has some links to more advanced issues including motion path which is what you asked for (though I see now that I can't access it). Fifth result is also a tutorial about moving cameras (https://www.arch.columbia.edu/index.php?pageData=9634/ )

My point is I didn't post that link without actually checking the content... Let-Me-Google-That-For-You is just for fun :p

More specific how? Only animation with a moving camera?
If so, check the link above... And I'm sure others can contribute as well. If not, What exactly do you mean?

Hope this helps,
Benny
