Mod Mark said in the comments that it's from runescape. So Indeed they have much in store for runescape.
Too bad it's not :/
"Our tools guys recently created a brand new editor for creating cutscenes. Since then, our modellers, animators and video editors have been hard at work creating a brand new trailer for RuneScape. We are very happy with the results, especially given that this is the first time we’ve attempted a project like this before.
Thanks especially to Mod MikeW who created the original storyboard for this (expect a dev blog in the new year with more details). Please note that although this was all shot in our game engine (effects like depth of field are not faked), this trailer is not a teaser for any future content.
