The intro of Metal Gear Solid V: Ground Zeroes’ consists of a single camera shot, with no cuts. This same style will be applied to the cutscenes of The Phantom Pain, as well as transitioning from and to gameplay seamlessly. According to Kojima, achieving this style is a pain.
Earlier Kojima has stated that this is done to emphasize the open world, and to connect the gameplay with the cutscenes, creating an ongoing sense of realism.
Today Kojima mentioned this technique again, comparing it to a more recent movie that applied it as well, Birdman.
BiRDMAN directed by Inarritu shows one continuous long take, surpassing Cuarón’s GRAVITY/Children of Men (his name’s in credit). “TPP” also offers one long shot which is pain in directing, taking the rhythm as not being able to edit inbetween the events.
TPP consist almost one-shot w/cut scene & gameplay (POV style). Only edit was made in the specific occasion to balance out. “BiRDMAN” was on the other hand more like stage performance where ensemble casts are framing in and out.
Last year Kojima compared this technique to the one used for another movie, Rope by Hitchcock. Hitchcock had to ‘cheat’ a little because of technical limitations.
