Epic Machinima Tool
Epic cinematic video:
UPDATE 12-16-16 Machinima Tool: This tools is not always updated for the latest live WoW.
Be careful with this one, Bliz does not like these kinds of tools and it is against TOS. The reason is because it can sometimes be used to give players (PvP) an unfair advantage.
On the other hand, its common use is for Machinima, so just use it for that (if you use it).
Personally, I love it and support it. Cheers!
