Watch: Over B's shoulder to film A speaking, then over A's shoulder to film B responding, cutting back and forth. When the two shots share the same size and face opposite ways, the audience feels they're talking face to face.A line-art demo that only illustrates the technique, not finished footage.

This is a step in making a film, not a visual technique. For the whole process, see Make an AI short from scratch.

Prompt templates are written from how generation models usually behave and have not yet been verified one by one with real generations. “Common pitfalls” are judgment from experience, not official limits.

01

When to use it

Almost every dialogue scene; interrogations, negotiations, confessions.

02

Prompt template

a shot/reverse-shot pair: shot 1, over B's right shoulder onto A, A on frame left facing right, speaking; shot 2, over A's left shoulder onto B, B on frame right facing left, replying. Matching shot size, camera height, and lighting.
03

Sample prompt · generate a video directly

The technique comes first, followed by the scene, action, performance and duration. Paste it straight into a video model and swap in your own characters and plot.

Shot one (shot): over the ticket clerk's right shoulder onto the delivery rider, who is on the left of the frame facing right, close shot, focus on his face; he asks, “There's really not a single bus left?” Shot two (reverse): over the rider's left shoulder onto the clerk, who is on the right of the frame facing left, close shot; she shakes her head: “Six tomorrow morning.” Both shots with the same size, the same camera height and the same warm yellow ticket-window light, 3 seconds each.
04

Common pitfalls

  • Light and background differ between the two shots, as if filmed in two places.
  • One shot wide and one tight, so the conversation feels unbalanced.
  • Crossing the line, so both people face the same way.
05

Parameter tips

Generate it as two prompts; keep the shot sizes symmetrical, and push in on both sides together at the emotional peak.
