Can you provide a link to the video you are comparing...in fact just embed it straight into this blog.
Why animate the band just playing? Well for one it is now cheaper to do so than to hire a sound stage, film crew, lighting technicians etc etc.
The reason a music video is usually told via animation, is because you can stretch the boundaries, than you would with live action. For example, Daft Punk’s Interstella 5555: The 5tory of the 5ecret 5tar 5ystem, an animated film about an intergaltic band using the duo’s music. That’s probably why the Hey Negrita vid was animated, to easily show the carnage and comedy inflicted upon the zombies?
Bold statement there Nick. I can tell you that I have not seen it, but it may well be a contributing factor for why Hey Negrita chose animation. Considering the huge number of zombie films in live action outweighing those made in animation, is it clear cut why animation was chosen as a medium? What does animation allow in this instance which live action would not? What are the down sides of using animation, especially from the client perspective?
There is plenty written about animation, its use and audience perception. Propoganda(educational) films are good place to start.
Since this was an animated film, was there anything about the film which made it particularly suitable to this medium?
