When Section 9 launches an assault on the Puppet Master’s headquarters, Department Chief Aramaki watches via a portable computer. It looks and behaves much like a modern laptop, with a heavy base that connects via a hinge to a thin screen. This shows him a live video feed.
The scan lines on the feed tell us that the cameras are diegetic, something Aramaki is watching, rather than the "camera" of the movie we as the audience are watching. These cameras must be placed in many places around the compound: behind the helicopter, following the Puppet Master, to the far right of the Puppet Master, and even floating far overhead. That seems a bit far-fetched until you remember that there are agents all around the compound, and Section 9 has the resources to outfitted all of them with small cameras. Even the overhead camera could be an unoticed helicopter equipped with a high-powered telephoto lens. So stretching believability, but not beyond the bounds of possibility. My main question is, given these cameras, who is doing the live editing? Aramaki’s view switches dramatically between these views as he’s watching with no apparent interaction.
A clue comes from his singular interaction with the system. When a helicopter lands in the lawn of the building, Aramaki says, "Begin recording," and a blinking REC overlay appears in the upper left and a timecode overlay appears in the lower right. If you look at the first shot in the scene, there is a soldier next to him hunched over a different terminal, so we can presume that he’s the hands-on guy, executing orders that Aramaki calls out. That same tech can be doing the live camera switching and editing to show Aramaki the feed that’s most important and relevant.
That idea makes even more sense knowing that Aramaki is a chief, and his station warrants spending money on an everpresent human technician.
Sometimes, as in this case, the human is the best interface.
