Seedance 2.0 Consistency Guide

Consistency is not a single toggle. In Seedance 2.0, consistency comes from how you design the shot, how you choose inputs, and what you ask the model to protect.

If your current outputs look good frame-by-frame but break across the full clip, the problem is usually not style. It is continuity planning.

What consistency actually means

In practice, teams usually mean one of four things:

• the same face stays the same face
• the same product keeps the same geometry
• the same hand interaction stays believable
• the same scene keeps the same visual logic

Those are related, but not identical. Solve the exact version you have instead of asking for a vague “more consistent” result.

Start by defining the invariants

Before you prompt, write down what must not change:

• face identity
• bottle or pack shape
• wardrobe
• background layout
• color palette
• hand-to-object relationship

Anything not placed on this list is more likely to drift.

Use the narrowest workable mode

The best consistency workflows usually follow this order:

1. text-to-video for broad concept exploration
2. image-to-video for first-frame lock
3. reference-to-video for identity or product lock

When continuity becomes the main objective, move to the more constrained mode rather than endlessly adding adjectives.

Build continuity into the shot

Keep the shot small

Consistency improves when the shot asks for:

• one subject
• one action
• one camera move
• one lighting setup

It gets worse when you ask for:

• multiple interacting subjects
• many props entering and leaving frame
• fast camera changes
• large pose shifts

Keep the framing honest

If the product or face must remain stable, keep it visible and readable. Tiny hero objects in wide shots are much harder to preserve than large, dominant subjects in tighter compositions.

Keep the visual language stable

If one shot says:

• warm daylight
• soft shadows
• natural lens feel

the next retry should not suddenly ask for:

• glossy high-contrast studio light
• extreme anamorphic look
• aggressive handheld movement

Continuity is partly a prompt problem and partly a shot-language problem.

Continuity rules for products

For ecommerce and product work:

• use a clean anchor image when possible
• keep one hero product in frame
• limit splash, particles, and extra props
• protect label readability and silhouette in the negative prompt

If the product keeps warping, the fastest fix is often to reduce motion complexity, not to add more descriptive copy.

Continuity rules for people and UGC

For creator or character work:

• use one strong identity anchor
• keep gestures simple
• avoid long multi-beat performances in one clip
• protect face, hands, and product visibility explicitly

If the person is speaking, do not also ask for heavy body movement, prop interaction, and a complex camera transition in the same shot.

How to keep continuity across multiple clips

If you are building a sequence instead of a single shot, keep these locked:

• aspect ratio
• core lighting direction
• lens feeling
• subject styling
• negative prompt guardrails

Think of each clip as a controlled variation, not a reinvention.

A continuity-first debugging checklist

When results drift, ask these questions in order:

1. Did I define what must stay fixed?
2. Is the selected mode too open-ended for this job?
3. Is the camera move too aggressive?
4. Is the subject too small in frame?
5. Are multiple prompts or references fighting each other?

This sequence usually finds the real cause faster than random regeneration.

Frequent consistency failures and fixes

What not to do

Do not try to “buy” consistency with:

• more adjectives
• more references that disagree
• longer prompts with multiple scenes
• bigger camera moves

Consistency improves when you reduce ambiguity, not when you increase volume.
