Prompt Blocks
Prompt Blocks
Good Seedance prompts usually read like stacked production notes.
Block 1: Style And World
Bad:
- cinematic
- high quality
- cool lighting
Better:
- what kind of piece this is
- what visual tradition it borrows from
- what the light behaves like
- what the environment feels like
Example shape:
[Style] high-end fashion commercial, photoreal, glossy black studio, controlled specular highlights, cool blue edge light
The point is not fancy vocabulary. The point is specifying a usable visual world.
Lighting — The Biggest Quality Lever
If you only add one thing to a weak prompt, add a lighting description. Lighting has the single biggest impact on video quality.
| Lighting Type | Mood | Use case |
|---|---|---|
| golden hour | Warm, magical, nostalgic | Lifestyle, outdoor, hero shots |
| rim light | Dramatic, cinematic | Portraits, action, product |
| natural window light | Soft, authentic, clean | Talking heads, UGC, corporate |
| overcast | Moody, neutral, grounded | Drama, documentary |
| neon | Urban, energetic, bold | Night scenes, music, fashion |
| backlit | Silhouette, mystery, contrast | Cinematic, artistic |
| candlelight | Intimate, warm, romantic | Lifestyle, mood |
| blue hour | Cool, melancholic, cinematic | Outdoor transitions, drama |
| soft diffused | Clean, commercial, safe | Product, corporate, talking heads |
| dramatic stage lighting | High contrast, performative | Keynote, presentation, music |
Block 2: Subject Identity
Say what must stay stable:
- person
- outfit
- silhouette
- product form
- key prop
If the identity matters, say so directly:
[Subject] one female performer, stable face, silver bob haircut, reflective black jacket, no extra performers
If it is a product, state the invariant:
[Subject] one foldable phone, purple-to-ice-blue gradient body, ultra-thin hinge, no human model
Block 3: Time Slices
Use explicit segments for any multi-beat prompt.
Examples:
[00:00-00:05]0-3 secondsShot 1 / Shot 2 / Shot 3
Each time slice should define:
- camera
- action
- payoff
Not an entire paragraph of unrelated wishes.
Time slices define what happens — not how the model cuts between them. Do not specify transition types or editing rhythm; the model handles that natively. See failure-modes #13.
Block 4: Camera Language
Specify one camera move per shot. Combining multiple moves causes jitter and instability.
The 8 Types
| Movement | Use it for | Example prompt phrase |
|---|---|---|
| Slow push-in / dolly in | Emotional focus, intimacy | slow push in toward her face |
| Pull-out / dolly out | Reveal context, scale | gradual dolly out revealing the full cityscape |
| Pan left / right | Horizontal scanning, following action | slow pan right across the mountain ridge |
| Tracking shot | Following subject movement | tracking shot following the runner through the crowd |
| Orbit / arc | Product showcase, hero motion | smooth orbit around the subject, 90 degrees |
| Aerial / drone | Scale, geography, epic establishing | aerial shot descending slowly toward the rooftop |
| Handheld | Realism, urgency, documentary feel | handheld camera, slight natural shake |
| Fixed / locked-off | Tension, stillness, stability | camera holds fixed framing |
Critical Camera Rules
- One camera move per shot — always
- Use rhythm words, not technical specs:
gentle,gradual,smoothwork —24fps,f/2.8do not - Separate subject motion from camera motion: "the dancer spins slowly, camera holds fixed framing" — not "spinning camera around a dancing person"
- The camera should intensify as the scene intensifies, not show off independently
Block 5: Action Choreography
The subject needs a visible behavior:
- sings
- points
- unfolds
- snaps fingers
- cuts vegetables
- presses NOS
- draws sword
If the hero is not doing anything concrete, Seedance fills the gap with mush.
Block 6: Sound And Rhythm
This is one of the repo's biggest tells about Seedance.
The better prompts often specify:
- beat type
- SFX cues
- dialogue energy
- cut rhythm
Use sound when it affects motion or pacing:
[Sound] trap beat, heavy 808 kick, metallic click on product unfold, cuts land on beat
Block 7: Constraints
Seedance only responds to positive instructions. Negative phrasing (no blur, don't shake) is ignored by the model. Always rewrite constraints as what you want to see:
| You want | Don't say | Say this |
|---|---|---|
| Good anatomy | (nothing) | anatomically correct, natural proportions |
| Stable hands | no broken hands | detailed natural hands, correct finger count |
| No shaking | no camera shake | stable framing, smooth motion |
| No flickering | avoid flickering | consistent lighting, no temporal flicker |
| Person stays consistent | don't change the face | avoid identity drift, consistent appearance |
| Clean background | no clutter | minimal clean background, simple composition |
| Realistic motion | no stiff movement | physically accurate, natural motion flow |
Use constraints to preserve the core subject, not to write a wall of generic negatives.
Block 8: Intensity And Motion
Seedance responds to explicit intensity. Never be vague about how fast or strong something is.
| Weak | Strong |
|---|---|
| car drove by | car blazed past at high speed |
| wings flapping | wings beating vigorously, rapid powerful strokes |
| she walked | she strode with purpose, quick determined steps |
| fire burned | fire erupted violently, flames leaping 10 feet high |
| rain fell | heavy rain sheeted down diagonally in the wind |
| he nodded | he gave a sharp decisive nod |
Useful intensity words: vigorous, rapid, explosive, forceful, sudden, dramatic, gentle, gradual, subtle, delicate.
Avoid the literal word fast — it is the #1 quality killer, causing jitter, artifacts, and unstable output. Use high speed, vigorous, rapid instead.
Practical Rule
If a prompt block cannot be linked to a visual decision, cut it.
