Niš Fortress
At least three positions
Each video has a filming point and a camera direction. The sightlines from all positions meet at the same place on the rampart — for an AI fabrication to be convincing, the same fire would have to look consistent from each of these points: the same size, in the same place, with the same smoke and at the same time.
Landmarks: South bank of the Nišava, looking north-west across the river: the lit Fortress Bridge at the left edge, embankment terraces, fireworks above the Fortress, red flares and flames along the rampart.
Position of the earliest video (19:30:02). Cameras face north-west (≈ 319–333°).
Landmarks: The crowd on the southern part of the Fortress Bridge and King Milan Square, where the rally ended: a lamp post with a coiled cable (ring), a blue square sign, flags; across the river, flames along the top of the rampart and red flare smoke.
Most posts come from here, but reposts, screen recordings and stills of the original are not counted as separate angles. Cameras face north (≈ 0–22°).
Landmarks: Closer to the rampart, on the northern part of the bridge: a round crenellated stone tower on the left, a traffic light and a lamp post, flames along the wall on the right.
The closest position, about 30 m north of position B; cameras face north-east (≈ 31–32°).
