AI short dramas: keep the character and story consistent across shots

Start with a story that fits three shots

A short drama needs a change the viewer can understand. For this invented exercise, a courier reaches a closed shop, notices a light inside, then decides to knock. This gives you an arrival, a discovery and a decision. You can sketch all three on paper before choosing a tool or spending generation credits.

The useful question is whether the viewer can follow the same person through that change. A beautiful isolated frame is only one part of the answer. The following production plan is our own suggested exercise, not a report of a completed film.

Make a small continuity sheet

Write down the character's hairstyle, jacket, bag and distinguishing features. Add the shop door, the time of day and the direction from which the courier arrives. Mark which details must survive every cut and which can change deliberately.

Runway's Gen-4 Image References guide ↗ describes reference-based character and scene workflows. Use that specific guide as one possible starting point; references guide generation but do not replace inspection of each output. Keep a selected reference beside your continuity sheet so a changed bag or jacket is easier to spot.

Give each shot one job

Shot one establishes the closed shop and the courier approaching. Shot two shows the light behind the door from the courier's point of view. Shot three returns to the courier raising a hand to knock. Write the necessary action and framing beside each sketch. This limits how many things must work in one generation.

Runway's Gen-4 Video Prompting Guide ↗ separates motion description from details already present in an input image. In our exercise, the still image establishes the person and doorway, while the motion instruction describes the approach or hand movement. Check the guide for the model you actually select; these references are about Gen-4 and are not a claim that it is the newest model.

Review the cut, not only the clip

Place the sketches or selected frames next to each other. Ask whether the courier faces a compatible direction, the bag stays on the same side, and the light appears before the reaction. If a shot fails, identify the missing story information before rewriting every prompt.

Plan sound and subtitles after the visual sequence reads clearly. A short caption can explain the decision, but it should not repair a missing discovery shot. For this exercise, keep the dialogue to one line.

Try a low-cost pre-production exercise

Prepare three sketches, one continuity sheet and a single sentence describing the turning point. Ask another person to put the sketches in order without seeing the script. If the sequence is unclear, revise the storyboard first. This check requires no generated video. Later, if you choose to generate clips, record the model, settings, discarded attempts and actual cost; a plan is not evidence of a finished result.
