"Trailer Artist" still needed?

I was perusing the active threads and saw one about a "trailer artist needed for dev videos." I am unable to access this thread as I'm a lowly member (even though I'm a contributor).

What exactly does one mean by "trailer artist;" does that imply "video editor?" If so that's my actual profession (like, how I make a living, not just a hobby) and would like to either actually help out or at least provide useful input.

I've been working with the Skywind project as a writer but am happy to provide video help as well, if that's what "trailer artist" implies.
