How to Keep Characters Consistent in Seedance 2.0 Mini Videos

Keep a recurring character consistent by locking one approved reference set and one short identity description before you generate the sequence. Then change only the shot-level elements-camera, action, location, lighting, and emotion. Where your Seedance 2.0 Mini environment supports them, use image references, reference video, or video extension as continuity inputs, test them in short clips, and reject takes that alter the character's defining traits.

The key is not adding more description to every prompt. It is separating what must remain unchanged from what the story needs to change.

Start with the Inputs Available in Your Environment

Officially documented, environment-dependent: Seedance 2.0 Mini implementations can support text-to-video, image-to-video, reference video, reference audio, video extension, and video editing. The exact inputs, limits, labels, and compatible combinations vary by provider.

Choose the strongest continuity input your environment offers:

1
1. Reference-led image-to-video: Use an approved visual reference as the starting point when image input or character reference images are available. This is the clearest way to carry visible traits such as hairstyle, garment silhouette, and a signature accessory into a new shot.
2
2. Reference-video workflow: If reference video is available, use it to guide the desired style or motion. Treat it as motion or visual guidance, not as a guaranteed identity lock.
3
3. Video extension: If you need the next moment to follow directly from an approved clip, an extension workflow can continue an existing video from a text description. Test the result before building a sequence around it.
4
4. Text-only workflow: When no usable visual reference option is available, rely on a tightly controlled character bible and repeat its identity block unchanged in every shot.

Some documented implementations accept one to four reference images for characters, avatars, clothing, or environments; another supports larger multimodal reference sets. Do not assume those limits apply everywhere. Verify your particular environment before planning an asset package.

For a fictional courier named Mara, a compact reference set could include:

1
1. A front three-quarter portrait
2
2. A full-body wardrobe view
3
3. A close image of her red enamel star pin
4
4. A neutral, well-lit view that clearly shows her short curly bob

Use only assets you have the right to use. A virtual-avatar option, where available, does not create permission to use a real person's likeness.

Build a Character Bible Before Writing Shots

General creator best practice: A character bible should be brief enough to repeat without contradiction and specific enough to identify the character at a glance.

Create one fixed identity block, then place shot instructions after it. In one documented API, a text prompt is required and limited to 2,000 characters, which is a practical reason to keep the repeated description compact even though that exact limit is not universal.

For Mara, the fixed block might be:

Mara, adult woman, warm brown oval face, short black curly bob, athletic build, mustard utility jacket, charcoal trousers, red enamel star pin on the left lapel.

A shot prompt then adds only the variable material:

Mara, adult woman, warm brown oval face, short black curly bob, athletic build, mustard utility jacket, charcoal trousers, red enamel star pin on the left lapel. Three-quarter medium shot, walking through a rainy night market, looking alert, reflected neon light, controlled handheld camera movement.

Avoid rewriting the identity from scratch for each clip. "Short black curly bob" in one prompt and "long wavy dark hair" in another is not visual variation; it is a contradiction. The same applies to changing the outfit's color, body description, or signature accessory without a story reason.

Test Continuity Before Producing the Full Sequence

Do not discover the limits of your character package after generating every planned shot. Run a small proof set first.

Officially documented, environment-dependent: One set of model guidance recommends starting with 5-second clips while prototyping, then increasing duration for final versions. Use short tests to make decisions quickly, not as proof that a character will remain stable in every future scene.

Run a Three-Clip Stress Test

Generate the same character under three ordinary changes:

1
1. Identity baseline: A calm, front or three-quarter view in simple lighting.
2
2. Movement test: The same character walking, turning, or handling a simple object.
3
3. Context test: The same character in a different location or lighting condition.

Keep the reference package and identity block unchanged. Change only the variables required by each test.

Then choose the next action:

1
1. All three clips hold: Approve the reference set and begin sequencing.
2
2. One trait drifts repeatedly: Revise the reference package or simplify the variable instructions.
3
3. The continuation looks closer than independent clips: Use extension for directly connected story moments, while still reviewing every result.
4
4. The character changes across all tests: Rebuild the identity block before adding more complex scenes.

A fixed-camera control or a reproducibility seed may be available in some implementations, but neither is documented as a guarantee of consistent character rendering. Treat them as workflow options to test, not as replacements for references and review.

Use a Continuity Gate Before Accepting a Clip

A clip is not ready simply because it looks polished in isolation. Compare it directly with the previous approved shot.

General creator best practice: Review these elements at the edit point:

1
1. Face shape and overall recognizability
2
2. Hairstyle, hairline, and color
3
3. Age presentation
4
4. Body proportions
5
5. Wardrobe silhouette and core colors
6
6. Signature accessories
7
7. The character's apparent scale and presence in the scene
8
8. Whether the cut makes the two shots feel like the same person

Use a simple pass/fail rule: if a viewer would reasonably read the clip as a different character, do not use it as the next continuity shot.

Correct the First Visible Problem

Change one likely cause at a time. If you rewrite the character, action, lighting, composition, and environment together, you will not know what improved-or caused-the drift.

There are also implementation-specific input trade-offs to check before designing a repair workflow. In one documented API, reference-image inputs cannot be combined with first- or last-frame images. In that same implementation, a last-frame image works only when a start-frame image is also supplied. Choose the continuity method your environment actually permits rather than assuming all reference controls can be stacked.

Finish the Sequence with Editorial Continuity

Once you have approved clips, editing can protect continuity without asking generation to solve every problem. Select the best matching takes, cut away before a mismatch becomes obvious, use tighter crops where appropriate, and keep color and transition choices consistent between shots.

Bring approved clips into CapCut for final sequencing, cut-point comparison, and visual continuity work. Consistent transitions across multiple videos can help a sequence feel intentional, but they should not be used to hide an unresolved identity change.

Before producing the full video, verify the tools available in your Seedance 2.0 Mini environment, lock the character bible, run the three-clip stress test, and approve only the clips that pass your continuity gate.
