0 to 4.5 s: the stand-off
One wide, still shot of a narrow brick alley with fire escapes, green dumpsters, cardboard boxes, bin bags, wall lamps and cracked asphalt. The Loser stands on the left and the Winner on the right, and they square up in martial-arts stances with small kicks and jabs. Check that there are exactly two people, that the alley matches the reference and that nothing is written on the walls or the bags. In the first five seconds or so there are dark bands across the top and bottom of the picture. They belong to the reference clip and stay.
