BURST FRAME — Universal

The BURST FRAME technique generates 20 consistent, full-resolution reference frames from a single Seedance 2.0 generation. Instead of running multiple separate image generations, all 20 angles or moments are encoded into one Rapid Fire video prompt. Seedance's consistency within a single generation ensures every frame shares the same subject identity, visual style, and lighting logic. ffmpeg then extracts the individual frames.

The result: 1 prompt → 1 Seedance video → 20 usable reference frames ready to feed back into Seedance as start frames, or into Nano Banana as consistency anchors.

Step 1 — Identify the subject type

Determine which category the subject falls into. This shapes the angle strategy.

| Type | Examples | Primary goal | |---|---|---| | Character / humanoid | Knight, samurai, cyberpunk hacker, alien, robot | Pose variety + identity lock across angles | | Creature / non-human | Dragon, wolf, mech beast, monster | Form clarity from key angles + detail closeups | | Product / object | Sneaker, weapon, armor, gadget, jewelry | Material texture + 360° coverage | | Environment / world | Cyberpunk city, fantasy forest, space station | Establishing coverage + atmosphere | | Hybrid | Character in world, creature with rider | Identity lock on primary + world integration |

---

Step 2 — Lock the inputs

Extract from context or ask:

| Input | Examples | |---|---| | Subject | Dark fantasy knight, cyberpunk samurai, dragon, artifact | | Visual style | Cinematic 3D, cel animation, hyperrealistic, stylized | | Environment | Studio void, battlefield, rooftop, forest, canyon | | Color system | Dominant palette + accent relationship | | Animation / live action | Seedance handles both; specify if key |

If the user provides a reference image, extract subject, style, and environment from it.

Step 3 — Build the 20-shot list

Select the 20 shots that best serve the subject type and context. Draw from the banks below.

Character / Humanoid — Angle Bank

Full figure

• Dead front (0°) — full height, centered, confrontational
• Dead rear (0°) — back silhouette, armor/costume detail
• Side profile (90°) — complete silhouette line, stance
• Front 3/4 (45°, one side) — dominant shoulder + face readable
• Rear 3/4 — back detail + opposite shoulder
• Overhead top-down — helmet/crown, shoulder spread, footprint
• Ground level extreme low — looming, heroic, menacing
• High angle looking down — vulnerability or grandeur

Portrait / Detail

• Face extreme close-up — eyes, expression, skin/texture detail
• Helmet or headgear detail — visor, horn, crest, battle damage
• Chest armor close-up — crest, material, engraving, wear
• Hand close-up — gauntlet, weapon grip, sigil, gesture
• Weapon or accessory detail — blade, hilt, crossguard, material
• Boot / foot close-up — ground contact, material, weight
• Back detail — cape, spine armor, cape clasp, wings

In-Context

• Action pose — attack — weapon raised or mid-swing
• Action pose — defend — shield raised, guarded stance
• Environmental integration — subject in world, environment visible
• Dynamic motion blur — movement through frame, speed lines
• Silhouette against sky or light source — pure form read

Creature / Non-Human — Angle Bank

• Full body front — complete form, scale reference
• Full body side — complete silhouette, limb proportion
• Three-quarter front — dominant mass + key features
• Overhead — wing span, body footprint, symmetry
• Low front looking up — scale and threat
• Head extreme close-up — eye, horn, teeth, texture
• Claw or limb close-up — weapon appendage detail
• Spine or dorsal — back ridge, fin, wing root
• Tail close-up — tail tip, scale texture, coil
• Mid-action (leap, strike, spread wings) — dynamic moment
• Environmental scale — creature small in world, world visible

Product / Object — Angle Bank

• Dead front — face-on, symmetrical
• Dead rear — back face
• Side profile left — clean silhouette
• Side profile right — opposite silhouette
• Top-down — footprint, top surface
• Three-quarter front — primary reading angle
• Three-quarter rear — secondary reading angle
• Bottom/underside — sole, base, engineering
• Material close-up (x3) — texture, finish, detail at different points
• Brand/logo close-up — badge, mark, signature element
• Environmental context — object in use or in world

Environment / World — Shot Strategy

• Wide establishing — full environment, horizon
• Mid establishing left — leading into scene
• Mid establishing right — opposite reading
• Atmospheric foreground — bokeh detail, texture, scale element
• Overhead aerial — full geography from above
• Ground level — immersive, inside the world
• Key architectural detail (x3) — specific elements that define the world
• Light source close-up — neon, fire, moonlight, volumetric ray
• Reflection / surface — puddle, mirror, window, lake
• Human scale element — figure-scale reference in the world
• Transition moment — dusk, fog roll, weather

Step 4 — Write the Seedance BURST FRAME prompt

Use this template. One line per shot — verbosity exceeds the character limit.

same subject throughout all shots, same [subject name + key visual trait] consistent identity every shot.

10 seconds, 20 shots (Rapid Fire). [Subject identity sentence]. [Environment]. [Style + mood]. [Color palette]. [Film format].

[1] [one-line shot description].
[2] [one-line shot description].
...
[20] [one-line shot description].

Global: same [subject] identity every shot, [environment constraint], [style/lighting rule], no [unwanted elements]. Audio: [sound design].

Identity lock — non-negotiable

Open every prompt with the identity lock. The subject's key traits (color, material, markings, silhouette) must be named explicitly and repeated in the Global line. Seedance drifts without this.

same character throughout all shots, same dark fantasy knight in obsidian plate armor consistent identity every shot.

Style language — use precise descriptors

| Style | Exact language | |---|---| | Cinematic 3D | cinematic hyperrealistic 3D render, volumetric lighting, subsurface skin scatter | | Cel animation | delicate thin black line work, vivid flat color within lines, cel animation quality | | Dark fantasy | dark fantasy aesthetic, deep shadow, candlelight or cold moonlight, desaturated with accent color pop | | Cyberpunk | neon-saturated cyberpunk, rain-slicked surfaces, holographic overlay, crushed blacks | | Editorial photo | luxury editorial photography, medium format lens compression, clean and minimal | | Anime | high-contrast anime style, speed lines, expressive key frame, flat cel shading |

Physics — name these explicitly

Seedance won't infer physics correctly without explicit direction:

| Element | Exact language | |---|---| | Cape / cloth | cape billowing under wind load, fabric catching light at trailing edge | | Weapon swing | sword arc motion blur trailing from blade tip | | Particle effect | ember sparks radial displacement from impact point | | Rain / wet surface | wet surface mirror reflection, rain streak motion blur | | Smoke / breath | breath visible as white condensation in cold air | | Fire / glow | fire source illuminating underside of subject, heat shimmer rising | | Wing spread | wing membrane stretching, leading edge catching light | | Speed / movement | radial motion blur from center of action outward |

Step 5 — ffmpeg extraction

Always include this in your output. The ffmpeg command is the final step the user needs — don't skip it.

# Fixed interval — 1 frame per 0.5 seconds (10s video = 20 frames)
ffmpeg -i your_video.mp4 -vf fps=2 frame_%02d.png

# Scene-change detection — better when Seedance cuts are crisp
ffmpeg -i your_video.mp4 -vf "select=gt(scene\,0.25)" -vsync 0 frame_%02d.png

Tell the user to drop the Seedance video here when ready — offer to run extraction directly.

Environment presets

Apply these when the user names an environment without specifying the visual system:

Studio void Seamless [color] backdrop, matching floor, soft overhead diffused light, no hard shadows, mirror floor reflection. No environment, no props, pure subject.

Dark fantasy battlefield Smoke-filled battlefield, distant fire on horizon, cold moonlight through cloud breaks, churned mud ground, armored corpses in deep background. Desaturated, deep shadow, single accent color.

Cyberpunk rooftop / street Rain-soaked neon city, reflective tarmac, holographic ad panels, night environment, crushed blacks. Cold blue + saturated neon accent.

Fantasy forest Ancient forest cathedral, god rays through dense canopy, moss-covered stone, fog at ground level, teal-amber grade.

Void / abstract Pure black void environment, subject floating, dramatic single-source rim light, studio fill, no environment cues.

Space / cosmic Deep space, distant nebula cloud, star field, planet limb visible, cold starlight as key, warm engine glow as fill.

Quality rules

• Identity lock is non-negotiable — open every prompt with same subject throughout all shots, same [subject description] consistent identity every shot
• One line per shot — shot descriptions that run longer than one line push past Seedance's character limit and cause drift
• Name style and physics explicitly — unnamed physics and style ambiguity renders flat, generic, weightless
• No STOP MOTION — rapid-fire pacing and freeze frames conflict with BURST FRAME technique
• Repeat the subject description in the Global line — this is a second identity lock that prevents late-shot drift
• Keep color system in the header — stating the palette once globally in the intro line overrides per-shot color drift

Reference: subject type examples

For automotive BURST FRAME (cars, bikes, trucks), use the burst-frame-cars skill instead — it contains a dedicated automotive angle bank, environment presets, and worked examples specific to car photography.

For this generic skill, the following subject types have been used successfully:

• Dark fantasy knight (studio void, battlefield)
• Cyberpunk samurai (rooftop, rain-slicked street)
• Creature — dragon (aerial, cave, cliff environment)
• Product — sneaker, weapon, armor piece
• Environment — cyberpunk city block
