This is the best tool that I was able to find, maybe there are a lot better tools. But hey, doesn't WoL already have it?
You know how to make a cinematic, right - you just don't know how to change the pitch? To change pitch, click on the little camera icon like if you were going to create a new camera movement, then click on "zoom" or pitch, and you can choose the desired pitch. Of course you are still able to zoom in and out.
