Legal advice on Envato footage ?

Hello!
Just a legal question. I’ve read the terms and conditions of the licenses, but I’d rather double-check.
I’m working on a Fake Out Of Home project for a social networking campaign for a brand. To do this, I’ve spotted some footage I’m interested in on Envato. One of them is a shot of the Oculus WTC Station in NYC. I’m supposed to add a layer of CGI that interacts with the building’s architecture. We’re talking about something that respects this architecture, I’m not distorting or destroying it (“fair use”). However, am I covered in terms of rights? Does the Envato license cover the use of the image of the building (in addition to the use of the footage itself)?
Let me know
