Blue Planet III Intentionally Retains Flaws: Over-Perfection Makes the Footage Look AI-Generated

BBC's Blue Planet III has done a counterintuitive thing: it leaves far-from-perfect clips in the official cut.

As reported by The Verge, this nature documentary wants to prove its authenticity with these retained flaws. Executive producer Elizabeth White told The Guardian that back in the days when there was too much plankton floating in the water, or ships and buoys appearing in the frame, the team would cut the footage, recompose the shot, or even discard the material completely if the water quality was not good enough. All these elements are now kept in the final work.

The logic behind this move is easy to figure out. One of the most common telltale signs of AI-generated images and videos is excessive smoothness, seamlessness and cleanliness. Nature documentaries used to be famous for crystal-clear footage, and audiences have long taken wallpaper-like perfection as a sign of high quality. After generative models can mass produce this kind of perfection, perfection itself has become suspicious.

The choice Blue Planet III made is somewhat like leaving production traces in the footage: plankton, passing ships, and ordinary water conditions all serve as circumstantial evidence that the footage is filmed in real scenarios. This practice may not convince everyone, since AI can also be prompted to generate noise and flaws. But it points out a new shift: when flawless footage becomes cheap, imperfections start to take on the function of credibility endorsement.
