In my view, the Black and Yellow trailers are definitely canon. The Black Trailer is to establish Blake's back-story. Additionally, both it and the Yellow Trailer have a lot of world-building, establishing the nature of the world in which the characters live.

The Red Trailer is a bit iffy; thanks to it appearing in the Opening, the Cliffside Altar is established as canon but I'm not sure about the rest. Monty has said that Ruby is OOC in it.

The White Trailer is very difficult to assess. The way the others react to Weiss, she doesn't seem like a pop idol. The Armour Giant is also very different from the other enemies faced both in the trailers and in the show so far.
