You probably saw the fancam last week. Twenty-six seconds of focused crowd-eye coverage of one member of one of the larger K-pop groups, cut to a snippet of the new single, posted to a fan account with thirty thousand followers. It went viral on Tuesday. By Wednesday afternoon it was clear that no human had made it.

The fancam was generated. Not the footage — the footage was real, lifted from a recent music show appearance — but the cut, the timing, the colour grade, the caption, the sub-thread of replies that pushed it into the algorithm. All of that was a system. A small one, but a system.

The fan account did not run the system. Someone else did. The system was, by all accounts, an open-source toolkit being passed around in a corner of the discourse where the more obsessive parts of fandom have always lived.

What I want to talk about is what this does to fancam culture, which is one of the strangest and most generous corners of pop fandom and which has, until now, been recognisably human.

A fancam, as a form, has always been an act of love. Someone in the audience pointed a phone at one specific person on stage for a song and a half and stayed locked on. The cut was clumsy. The colour was bad. The energy was perfect. The form was the proof: a person had spent a song’s worth of attention on the bias, and the result was, in the deepest sense, a gift.

The autonomous fancam is not that. It looks like that. It moves like that. It hits the same emotional beats. But the act underneath it is, quietly, missing. Nobody chose. Nobody held the phone. Nobody cared, in the song’s worth of held attention, about the person on the screen.

The fans noticed. Not all of them, and not immediately, but the conversation on Wednesday was real. There were posts. There were threads. The most striking ones came from fancam veterans — the people who have been making these videos for ten years — and they were not angry. They were sad.

The sadness is the right register. The autonomous fancam does not steal anything. It does not pretend to be human. It just renders, smoothly and competently, an artefact whose value was always in the human roughness. The competence is what is wrong.

Most of the fan accounts I follow have, since Wednesday, started adding a small mark to their own posts. A timestamp. A behind-the-scenes glimpse. A note about the camera they used. They are, in effect, hand-stamping their work. It is a small thing and it is happening across the fandom faster than I expected.

The platforms have not yet responded. The algorithm cannot tell, on the front end, the difference between a fancam made with hands and a fancam rendered by a system. Both look the same in the feed. The fans are doing the differentiation themselves, in the captions and the threads and the small marks.

That is, at the moment, working. It is working because the fandom is small enough and tight enough to know who is who, and because the autonomous-fancam toolkit has not yet got cheap enough to flood the zone. Both of those things will change.

What will the fandom do then? I think — and this is a hopeful read — the fandom will do what fandoms have always done: develop new rituals to mark presence. Fancam veterans will start posting more pieces, with more handheld marks, and the audience will learn to look for the marks. The autonomous fancams will, paradoxically, make the human ones more recognisable as gifts.

The bias is on stage. The bot is in the discourse. The fans, the actual fans, are still in the room with the bias. That has not changed. What has changed is that the room now needs proof, and the proof is the small handmade mark.
