There's already short movies of DA made by fans , although it's done with the game engine.
Bioware also has some fan creation months where they show fanart etc...
And there's countless let's play DA O/2/Inquisition where people make money with Youtube.
So even if there isn't any official word about fan creation , I'd say Bioware is pretty supportive about it.
Now if it were me I'd be careful , people make money with the DA franchise via fan art , let's play etc...it seems so far Bioware is alright with that , but it doesn't mean it's always going to be the case.
And if you make a video , make sure it's understood it's fan work and nothing official , no Bioware /EA trademark or whatever.
Anyway I'm no expert but as far as I can tell the worst that can happen on youtube is the video is taken down for copyright issues.And there's a higher chance you'll have trouble with copyrighted music than Bioware asking to remove the video anyway.
