Hides where the cut happens so several clips look like one take.
Long-take-style ads that follow a space without a break.
Write the last 0.5 seconds of A as "the camera passes a dark pillar or someone's back, and the frame is blocked" and the first 0.5 seconds of B as "emerging from behind the same object, revealing a new space". Cut at the most blocked frame, and if needed cover it with a 3 to 6 frame xfade.
Two-shot sequence: Shot 1, the camera tracks a girl walking down a bright corridor and passes behind a dark stone pillar that fills the whole frame in the last half second; Shot 2 starts on the same dark pillar filling the frame, then slides away to reveal her in a sunlit courtyard, same walking pace, 3 seconds each.
