Shake is a discontinued image compositing package used in the post-production industry developed by Nothing Real for Windows and later acquired by Apple Inc. Shake was widely used in visual effects and digital compositing for film, video and commercials. Shake exposed its node graph architecture graphically. It enabled complex image processing sequences to be designed through the connection of effects "nodes" in a graphical workflow interface. This type of compositing interface allowed great flexibility, including the ability to modify the parameters of an earlier image processing step "in context" (while viewing the final composite). Many other compositing packages, such as Blender, Blackmagic Fusion, Nuke and Cineon, also used a similar node-based approach.
