Social Media Video Creator

End-to-end pipeline: Brand Files → Storyboard → Reference Images → Seedance 2.0 Video.

Reads your brand identity, ICP, and messaging documents to produce on-brand social video — fully optimized for Seedance 2.0's instructional prompt grammar and your target platform.

Agent Execution Protocol

Step 1 — Read Brand Files

Before writing anything, the agent MUST read all available brand files. Look for them in the working directory or any brand/ subdirectory:

File	What to extract
brand-identity.md	Visual style, color palette, tone, logo/product aesthetics, brand personality
ICP.md	Target audience — who they are, their pain points, what motivates them
messaging.md	Core value props, hooks, CTAs, campaign themes, taglines

If a file is missing, proceed with what's available and note the gap.

---

Step 2 — Write the Social Post + Storyboard

Use brand context to produce:

Social Post Copy (for caption/copy):

• Hook line (first 1–2 sentences — must stop the scroll)
• Body (3–5 sentences: problem → solution → proof → CTA)
• Hashtags (5–8 relevant tags)
• CTA (one clear action)

Storyboard (match duration to platform spec):

0–3s:  [Opening scene — hook/visual surprise — camera move]
3–7s:  [Core message — product/subject in action — camera move]
7–10s: [Resolution — brand moment — CTA text on screen]
10–15s: [Logo/tagline hold — background music fade]

Tone must match brand personality. If brand is playful → upbeat transitions, bright grade. If brand is premium → slow reveals, dark luxury aesthetic, moody lighting.

Step 3 — Craft the Seedance 2.0 Director Prompt

Transform the storyboard into a technical Director Brief for Seedance 2.0.

Rules:

1. Never use vague descriptors ("beautiful", "amazing", "8k"). Use technical cinematography language.
2. Always specify camera movement, lens type, and lighting physically.
3. For 10s+ videos, use timecode segments: 0–3s: [...] 3–7s: [...] 7–10s: [...]
4. Integrate @image1, @image2 reference tags if images are provided.
5. Always include sound direction (even brief) — Seedance generates audio.
6. Lead with composition, end with texture and micro-motion.

Director Brief Template:

[SCENE] {environment, lighting, time of day}
[SUBJECT] {product/character/subject with specific detail}
[ACTION] {what happens — fluid, continuous, physically plausible}
[CAMERA] {movement + lens + framing}
[STYLE] {color grade, mood, film reference if helpful}
[SOUND] {music tone, sound effects, ambient}
0–Xs: {if multi-beat}

Step 4 — Generate Reference Images (If Needed)

When to generate reference images:

Scenario	Mode	Images Needed
Product showcase	i2v	1 product shot as first frame
Scene transition	first-last	2 images — opening and closing frame
Brand character	i2v	1 character reference
Pure concept	t2v	None — text only
Mood/style anchor	i2v	1 style reference image

Image generation — best models by use case:

Use Case	Recommended Model	Why
Photorealistic product/scene	google-imagen4-ultra	Highest realism, great lighting
Concept art / stylized	flux-kontext-pro-t2i	Creative fidelity, style adherence
Fastest turnaround	google-imagen4-fast	Speed with good quality
Highly detailed/editorial	hidream-i1-full	Fine detail, editorial quality
Character with identity	ideogram-v3-t2i	Strong text + character rendering

Reference image prompt format: Write a clean, technical image prompt (not a Seedance prompt). Include:

• Subject description + key product/brand visual elements
• Lighting (studio, golden hour, etc.)
• Shot framing (medium shot, product close-up, etc.)
• Mood/color palette matching brand identity
• NO motion language (this is for a still frame)

Execute image generation:

bash core/media/generate-image.sh \
  --model google-imagen4-ultra \
  --prompt "your image prompt" \
  --aspect-ratio 9:16 \
  --view

---

Step 5 — Generate the Video

Choose mode, tier, and camera based on content type and available assets.

Mode selection:

Situation	Mode	Command
No reference images	t2v	default
1 image (first frame)	i2v	--mode i2v --file ref.jpg
Start + end frames	first-last	--mode first-last --tier global --file start.jpg --file end.jpg
Multi-ref blend	i2v	up to 9 images

Invoke the script:

bash library/social/social-media-video/scripts/run-social-video.sh \
  --prompt "your director brief here" \
  --platform instagram \
  --camera drone \
  [--mode t2v|i2v|first-last] \
  [--file ref_image.jpg] \
  [--gen-ref "reference image prompt"] \
  [--tier global] \
  [--quality high] \
  [--view]

Platform Specs

Platform	Format	Aspect	Duration	Notes
Instagram Reels	Vertical	9:16	10–15s	Hook in first 1s
Instagram Feed	Square	1:1	10s	Static-feel works well
TikTok	Vertical	9:16	10–15s	High energy, fast cuts
YouTube Shorts	Vertical	9:16	15s	Max quality
LinkedIn	Landscape	16:9	10–15s	Professional tone
Twitter/X	Landscape	16:9	10s	Punchy, direct
YouTube (long)	Landscape	16:9	15s	Cinematic, slow builds
Pinterest	Portrait	4:3	10s	Lifestyle-forward

Tier note: Use --tier global or --tier vip for 1:1 and 21:9 formats. Chinese tier supports only 16:9, 9:16, 4:3, 3:4.

Camera Language Reference

Standard Camera Intents (--camera / --intent flags)

Intent	Movement	Best For
reveal	Slow crane up, wide establishing	Product launches, brand reveals
epic	Dolly in + orbit, low hero angle	Brand manifesto, emotional story
product	Static macro orbit, precision reveal	E-commerce, product demo
narrative	Tracking shot, Steadicam	Testimonials, story-driven
tense	Handheld jitter, dutch angle	High-energy, urgency
comedy	Reactive handheld, punchy zooms	Lighthearted brand content

Specialty Camera Intents (New)

Intent	Description	Best For
fpv	First-person subjective POV — immersive GoPro-style, continuous forward motion, peripheral detail close-ups	Action brands, travel, sports, tech demos
drone	Aerial cinematic flythrough — smooth gimbal-stabilized, sweeping laterals, descend from high altitude into scene	Real estate, luxury, outdoor brands, epic reveals
flythrough	Ground-level architectural flythrough — continuous dolly through space, seamless portal transitions	Architecture, interior design, venue showcases

FPV Prompt Enrichment:

Immersive first-person POV shot. Camera glides forward through [scene] at eye level.
Slight natural motion stabilization with GoPro-style wide angle.
Peripheral detail rushing past — [details]. Smooth continuous forward motion.
No cuts throughout. [Subject] visible in foreground periphery.

Drone Flythrough Prompt Enrichment:

Cinematic aerial drone shot. Camera descends from 200m altitude toward [subject/scene],
sweeping lateral arc as it descends. Gimbal-stabilized smooth motion.
Golden hour atmosphere, long shadows across [terrain/scene].
Final frame settles into medium establishing shot.
Aerial cinematography, DJI Inspire aesthetic.

Prompt Quality Checklist

Before finalizing the Seedance prompt, verify:

• Scene environment is physically specific (not "nice background")
• Camera movement named explicitly (dolly in, orbit, drone flythrough, FPV, etc.)
• Lighting described technically (volumetric god rays, rim lighting, soft diffused, etc.)
• Subject/product described with visual specifics from brand-identity.md
• Sound direction included (even one line)
• Timecodes used for 10s+ videos
• @image1 etc. referenced if images are provided
• Brand CTA or tagline included in final seconds
• No vague adjectives ("amazing", "beautiful", "stunning") — replaced with technical terms

Example: Full Workflow

User: "Make an Instagram Reel for our cold brew coffee brand, drone shot, premium feel"

Step 1 — Brand read: Read brand-identity.md (minimalist packaging, dark roast, black + gold palette), ICP.md (urban professionals 25–40, values quality), messaging.md ("Precision Brewed. Zero Compromise.")

Step 2 — Storyboard:

0–2s:  Drone descends over rooftop terrace at sunrise, fog below.
2–5s:  Drone swoops down toward coffee cup on white marble, steam rising.
5–9s:  Close-up orbit of bottle, specular gold highlights, ice cubes.
9–11s: Product settles, black screen fades in: "Zero Compromise." + logo
Sound: Minimal lounge beat, coffee pour sound effect at 5s.

Step 3 — Seedance Director Prompt:

0–2s: Cinematic aerial drone shot. Camera descends at 30° angle toward a rooftop terrace at sunrise.
Golden hour atmosphere, San Francisco bay fog below horizon. Gimbal-stabilized smooth descent.
2–5s: Drone rapidly closes toward a glass of cold brew coffee on white marble.
Steam curling upward. Macro lens approach. Caustic light patterns on wet glass surface.
5–9s: Slow precision orbit around cold brew bottle. Black matte label with gold embossed text catching
specular highlights. Ice cubes with subsurface light scattering. Commercial macro aesthetic.
9–11s: Static product hero shot. Letterbox crop, deep focus, black fade in from sides.
Sound: Minimal ambient beat, single piano note, coffee liquid sound effect at 5s mark.
Maintain cinematic color grade — deep blacks, warm gold midtones throughout.

Step 4 — Generate reference: google-imagen4-ultra → cold brew bottle product shot (9:16)

Step 5 — Generate video:

bash library/social/social-media-video/scripts/run-social-video.sh \
  --prompt "0–2s: Cinematic aerial drone shot..." \
  --platform instagram \
  --camera drone \
  --mode i2v \
  --file media_outputs/coldbrew_ref.jpg \
  --duration 11 \
  --tier global \
  --view

Common Mistakes to Avoid

1. Reading brand files and ignoring them — the storyboard must visually match the brand palette and tone.
2. Generic prompts — "a nice video of a product" produces generic output. Every token must direct.
3. Wrong tier for aspect ratio — 1:1 and 21:9 require --tier global or --tier vip.
4. Forgetting sound — Seedance generates audio. Direct it, or you get random results.
5. FPV with static subject — FPV requires continuous motion in the scene. Pair with movement-rich environments.
6. Drone without establishing shot — drone works best when it resolves INTO something (a product, a scene, a subject).
7. Too many scene changes in 5s — match complexity to duration. 5s = 1 beat. 15s = 3–4 beats.
