One midnight, chasing a deadline for a documentary about a vanished neighborhood, Chingliu found a clip he did not remember shooting: three minutes of empty streets at dawn, shot from a window with the camera slowly panning as if someone worriedly searching for something. The light was wrong for the day he thought he’d filmed that area—blue-pale, not the amber of his memory. He stared at the timecode: 00:03:43:12. The filename was a string of numbers that matched no project.
