After a few more testing, it looks like that the Temporal AA Effect gets not recordet. Even not when the scene is paused
through matinee or Set Global Time Dilation. In the Moment the Screenshot got taken, the Image in the Editor gets back to little Alias. So the only way to record absolutely perfect Movies is to take Snapshots with an external tool from the Monitor. This all occurs most notably in Scenes, where hard edges are present (Architecture).
