Section 4: Character Consistency · Lesson 4 of 5 (19 of 45) · 60 minutes · Evidence: Two-character continuity test
Two characters on screen double the ways a shot can go wrong. A generator may give both of them the same face, move one person’s scarf onto the other, or make a child as tall as an adult. Audiences notice these slips at once, even if they cannot say why the scene feels off. Today you learn to keep two people distinct, correctly sized and correctly placed.

What must a filmmaker understand before they can keep two or more identities separate and maintain wardrobe scale eyelines and screen direction?
Most generation tools were built to draw one subject well. Put two in a prompt and several failures appear. Identity blending is when features of one character leak into the other, so both get the same hair or the same face. Wardrobe moves across, so a red cap appears on the wrong head. Sizes drift. Left and right swap between shots. Each failure has a specific control.
Keep each character’s identity block as its own labelled paragraph, and mark who is who by position and by one unmistakable feature. For example: “Person on the left: [block A]. Person on the right: [block B].” Never merge the two descriptions into one flowing sentence. If a tool lets you attach a reference image to each character separately, attach each to its own character and nothing more.
Scale is the relative size of characters and objects in the frame. Write it as a comparison, not a measurement: “the boy’s head reaches her shoulder.” Fix one comparison per pair and reuse it. A generator drifts on scale most often in close-ups, where the difference is cropped away.
Screen direction is which way characters face and which side of the frame each occupies. If Nia is on the left looking right at Omar in the first shot, she stays on the left looking right in matching shots of that conversation. Swapping sides without a reason confuses the viewer about who is where. The eyeline is the direction a character’s gaze travels. When two characters talk, their eyelines should meet: one looks slightly right, the other slightly left. A character who stares off at the wrong angle breaks the sense that the two are in the same room.
Wardrobe continuity means every character wears the same clothes through a scene unless the story changes them. Colour-code the pair: give each character a dominant colour that the other never wears. Nia is yellow and grey; Omar is green and brown. Colour coding also helps viewers tell characters apart on a small screen, but not everyone sees colour the same way, so add a second difference such as a hat or a silhouette.
A student tests two market sellers, Nia (tall, yellow raincoat) and Omar (shorter, green apron). The first result gives both yellow raincoats. She rewrites the prompt with labelled blocks, adds “Omar comes to Nia’s shoulder” and “Nia on the left facing right.” The coats separate. Omar’s face still resembles Nia’s, so she generates each separately first and combines them afterward.
When a creator needs two characters in one image, the safest path is rarely one big prompt. Study how they break the job into controlled steps, and notice that most of the checking is visual.
The creator first builds each character separately, with a labelled reference and a locked description, so each one is stable on its own. They then write down the relationship: who is taller and by how much, who stands on which side, where each is looking. Only then do they request the two together. When a result blends or swaps features, they diagnose by symptom: wrong face means separate the descriptions or generate each one on its own and combine; wrong coat means strengthen the colour coding; wrong size means state the comparison again. The tool places both figures; the creator verifies each against its own bible and against the pair’s placement plan, one symptom at a time.
As you study, record each decision point in your production journal.
| Decision point | What the filmmaker does | What the tool automates | What still needs human review |
|---|---|---|---|
| Prepare each character alone | Confirms each reference and identity block works solo | Draws each character individually | Whether each character is stable before combining |
| Write the pair’s relationship | States relative height, sides, facing direction and colour codes | Nothing | That the plan matches what the script needs in this scene |
| Generate the pair | Uses labelled blocks and the placement plan in one prompt or in combined parts | Composes both characters in the frame | Face blending, wardrobe transfer, scale and side placement |
| Diagnose and correct | Chooses the control that fits the symptom and changes one thing | Redraws the result | That the fix did not break something else, such as eyelines |
Studio task: Diagnose face blending wardrobe transfer and scale mismatch.
Work in a trio. Your teacher gives you a flawed image or sketch of two characters with at least three continuity problems (for example, matching faces, one coat on both, and a child as tall as an adult). If no image is available, use the written description sheet your teacher supplies.
Coaching tips. Fix one symptom per revision so you know which control worked. If both characters keep getting the same face, stop prompting them together; produce each alone and combine the results in your editor. Use a colour code and a second difference, such as a hat or a bag, so the pair stays readable in grayscale. Name the characters by role and look, not by group membership, so that nothing in the prompt relies on a stereotype to tell them apart.
Character A (name, identity block, colour code): ______ Character B (name, identity block, colour code): ______ Relative size (comparison, e.g. B's head reaches A's shoulder): ______ Frame placement (who is left/right, who faces which way): ______ Eyelines (where each looks, so the two meet): ______ Wardrobe that does not move between them: ______ Problems found and the control used for each: ______
Studio task: Create a two-character interaction test with stable identity and placement.
Create a two-character interaction test with stable identity and placement, using two characters from your film (or one from your film and a second original character).
Checklist before you submit:
Name the control that prevented identity blending.
Deliverable: Two-character continuity test.
Submit the two-character continuity test. The file must use the course naming convention and include enough process evidence to show the student's decisions and revisions.

| Criterion | Advanced | Proficient | Developing | Beginning |
|---|---|---|---|---|
| The work addresses the stated story or production purpose. | The test is built around a real moment from the film and shows how the pair will be staged in that scene. | The test serves a clear scene from the film. | The test is a generic pair with little tie to the film. | The test has no story connection. |
| The student applies the required method accurately and produces usable capstone evidence. | Both characters are stable alone and together; the placement plan covers size, sides, eyelines and colour code and matches both frames. | The pair is mostly stable and the plan is complete. | The plan is partial or the frames contradict it. | No plan and no control over identity or placement. |
| The student identifies at least one quality issue and records a meaningful revision decision. | Diagnoses a specific failure, applies one matching control, retests and records the result. | Names a failure and records a fix. | Names a failure but the fix is unclear. | No failure or revision recorded. |
| The work complies with consent rights attribution privacy disclosure and school policy. | Characters are distinguished by role and appearance, not stereotype; both characters’ sources and permissions are documented. | Characters are distinguished fairly and sources are recorded. | Some shorthand relies on stereotype or records are incomplete. | Assigns protected traits as behaviour shorthand or records no sources. |
Requirement: Do not assign protected identity traits as shorthand for character behavior.
When you need to tell two characters apart, use design choices such as hats, colours, silhouettes and props, never a protected trait such as race, religion, disability or accent as a shortcut for personality or behaviour. Check that your pair does not make one group the villain or the helper by default. If a classmate or any real person is the model for a character, you need a signed release. Keep a note on any frame you rejected because of this check, and offer a text description of each frame for anyone who cannot see the image.
