Question about making Trailers/Music Video

Me and my team are in the process of creating Trailers and Music Videos.
My question is, is it alright to use EVO or any Tournament Footages to reference players coming to our tournament?

With all these copyright law popping around, I don’t want to be breaking anything.

So for example:
I create a trailer of let’s highlighting PRBalrog and I take footage from EVO.
Am i gonna get court ordered to stop that?

Somebody please explain to me so that I don’t get fined or what not.
