How to keep AI story characters consistent across scenes

Create the cast before drawing the story

Start with one or two recurring characters and a small number of locations. In Clippie, the story cast holds up to eight characters. Each character can have a name, a “Looks like” description and a picture. Describe the traits that must remain stable: body shape, clothing colors, hair or head shape, and one recognizable accessory.

Make the description concrete enough to reuse. “A small clay gardener with a round head, mustard raincoat and green watering can” is easier to compare across scenes than “a cute, memorable person.” Keep decorative details short so the identifying traits stay clear.

Keep a character sheet you can reuse

Separate permanent traits from temporary state. A red scarf belongs in Wren’s character description; a wet scarf belongs in a scene note. Changing the saved description to suit every shot can accidentally change the design for the rest of the story.

Use the same short sheet when you return for another episode. Keep the voice assignment too: a familiar silhouette with a completely different voice can feel like a new character. This production note is for your reference; it is not a special import format.

Check how the selected look uses references

Reference support depends on the selected look. Clippie’s model-based looks use character pictures when their image model supports references. Other Clippie styles carry the character through the written “Looks like” description. Saving a picture does not mean that every style will use it as an image reference.

Choose the look first, then prepare the character in that visual language. A photographic reference and a thin stick figure are very different representations. Compare the first few generated scenes before producing a long sequence, and revise the description or reference when an important trait drifts.

Make the cast easy to identify in every scene

Use the same name throughout the script. Clippie supports character mentions such as @Wren, which connect a named character to the cast. Avoid repeatedly renaming one character as “the stranger,” “the traveler” and “the man” when that makes the intended subject ambiguous.

Separate appearance from action. Keep the appearance description stable and change the scene instruction: walking toward the shelter, looking through the window, setting down the backpack. If a character should be heard but not seen, use the cast’s “Keep off screen” setting and describe what the viewer should see instead.

Fix the cause of a character changing between scenes

If the face or body changes, check whether the selected look uses the saved picture and whether the right character is named in the scene. If clothing changes, shorten the appearance note to its defining colors and shapes. If a prop appears twice, state who holds it and remove contradictory directions.

Compare the problem scene with its neighbors before regenerating. Keep the working look, cast and reference unchanged while you correct one scene instruction. If only the animated version drifts, return to the approved still and simplify the motion. Changing the whole cast to fix one shot makes it harder to tell what helped.

• Identity drift: check the cast, name and supported reference.
• Wardrobe drift: keep identifying clothing in the appearance note.
• Prop drift: specify the owner and position in that scene.
• Motion drift: simplify the action, then review the start and end frames.

Review continuity before adding motion

Look at the scenes as a sequence. Check the character’s silhouette, clothing, important props and relative size. A good individual image can still be wrong for the story if an object switches hands or a character suddenly wears a different outfit.

Correct mismatched stills before animating them. Motion does not repair an inconsistent starting image and can introduce its own changes. After animation, watch the transition between neighboring scenes and check the first and last frames. For a returning series, save the cast in the character library and use the same references for the next episode.

• Stable names and appearance notes.
• Reference support checked for the chosen look.
• Important props match neighboring shots.
• Voice stays assigned to the same character.
• Animated shots preserve the approved character design.
