"Machinima" productions can remain close to their gaming roots and feature stunts or other portrayals of gameplay. Popular genres include dance videos, comedy, and drama. Alternatively, some filmmakers attempt to stretch the boundaries of the rendering engines or to mask the original 3-D context. The Academy of Machinima Arts & Sciences (AMAS), a non-profit organization dedicated to promoting machinima, recognizes exemplary productions through Mackie awards given at its annual Machinima Film Festival. Some general film festivals accept machinima, and game companies, such as Epic Games, Blizzard Entertainment and Jagex, have sponsored contests involving it.\
