HD 816p (!) of the post-credits teaser/scene from Cap Blu-ray + screencaps

816p is the actual resolution of the teaser on the Cap Blu-ray, if you take into account the actual letter boxing of the film (with them it's 1080p, without it's 816p) and the pillar boxing of the teaser, much like in the cinemas.
