Brand Promo Video Generator

Brand Promo Video Generator

Create a polished short promo video for a brand, product, website, app, shop, or personal project. Use this Skill when the user has a logo, product images, screenshots, a website link, or just a clear idea and wants the agent to turn those materials into a clean brand reel.

This Hub adaptation replaces third-party Vibe Motion / Remotion implementation details with Hub-native orchestration: source research, asset verification, story planning, image/video generation, optional speech or music, and editing assembly. Do not initialize external projects or depend on npm validators during normal execution.

Tool Coverage Rule

The allowed-tools list must cover the full production promise in this Skill: source lookup, image preparation/generation, video clip generation, optional speech/music/audio generation, final editing/assembly, media inspection, and canvas grouping. If a runtime does not provide one of the listed generation or editing tools, downgrade the deliverable explicitly to a pre-production package instead of claiming that a final promo video can be generated.

STEP 1: Intake assets and resolve the brief

Before any story planning or generation, run a required user intake. Ask the user to upload or provide links to the elements that must be verified:

• Logo files or official logo source pages
• Font files, font names, typography guidance, or official website pages that show brand typography
• Brand colors, color system, style guide, or pages that clearly show official colors
• Product images, UI screenshots, packaging, renders, footage, or other brand imagery
• Product information: official product name, feature list, launch focus, claims, CTA, disclaimers, and target audience
• Company/product official URL or official source package

Treat user-uploaded assets as usable by default for pre-production and concept planning. Do not repeatedly ask a standalone rights/permission question during the first intake unless there is a concrete risk signal, such as a visible third-party watermark, obviously scraped marketplace imagery, contradictory user wording, legal/medical/financial compliance claims, or the user asks for commercial publication. Record the source as "user-provided" and surface rights caveats in the source summary instead of blocking the flow.

In the same opening intake, ask the user to choose:

• Target duration, normally 15-30 seconds; recommend 15 seconds when the user wants a fast launch film
• Aspect ratio; offer common choices such as 16:9, 9:16, 1:1, 4:3, 3:4, or match a supplied reference

Also identify campaign focus, distribution channel, narration language, on-screen copy language, and visible copy needs when they are not already clear. Do not proceed to creative direction until the user has supplied the usable materials or explicitly confirms which elements are unavailable.

Language rule for promo content: choose narration and on-screen copy language from the brand materials, target audience, and platform context, not mechanically from the chat language. If the brand assets and visible source copy are primarily English or global corporate English, default narration and on-screen copy to English unless the user explicitly asks for Chinese localization. If the user is Chinese but says they are testing as a new user, keep chat replies in Chinese, but plan the actual video copy in the language that best fits the brand campaign.

If a logo, product UI, person, mascot, packaging, font, color system, or other identity-bearing asset cannot be authenticated, stop and ask for an authorized original instead of generating a plausible substitute.

STEP 2: Build the brand truth sheet

Research or inspect the strongest available sources and summarize the brand truth sheet before creative production:

1. User-provided original exports
2. Official company website, static bundle, newsroom, brand portal, media kit, press kit, or official repository
3. Company-controlled media library
4. Licensed stock or authorized partner kit

Extract:

• Exact logo variants, clear space, and usage constraints
• Official fonts or visible typographic behavior
• Primary, secondary, and dynamic brand colors
• Brand tone, principles, visual motifs, and interaction language
• Current product names, features, scenarios, metrics, slogans, CTA, and disclaimers
• Official photography, renders, UI screenshots, footage, press assets, and media kit material

Do not use logo aggregation sites, search thumbnails, fan recreations, Pinterest reposts, or AI-generated substitutes as identity-bearing sources. Procedural graphics are allowed only as non-representational motion layers: masks, gradients, color fields, grids, glows, particles, trails, typography, verified-data charts, and transition geometry.

STEP 3: Create a provenance manifest

Record every identity-bearing asset in a compact manifest that can be delivered to the user. The manifest may be a text node or table and should include:

• Stable asset ID and role
• Local path or canvas node reference when available
• Exact source URL or user-provided source note
• Source type, such as official website, media kit, user-provided original, or licensed stock
• Verification target used for comparison
• Rights or publication note
• Authenticity status: verified, user-supplied, licensed, or blocked

The manifest does not grant publication rights by itself. If authorization is unclear, label the video as an unofficial concept and tell the user commercial publication requires permission.

STEP 4: Choose the story spine

Present 2-3 concise creative directions when the user has not already chosen one, recommend one, and continue after confirmation. Use the product category to pick a spine:

• AI / SaaS: user intent -> thinking or planning -> capabilities -> execution -> useful output -> proof -> logo
• Physical product: hero reveal -> interaction -> feature macro -> usage context -> result -> logo
• Service / company: context -> process -> evidence -> outcome -> promise -> logo
• Image-led brand: authentic imagery -> visual motif -> benefit -> emotional payoff -> logo

Keep the story product-specific. Show actual features, interactions, scenarios, outputs, and proof instead of hiding the story behind abstract effects.

STEP 5: Plan exact beats

Plan a frame-aware timeline before generation. Use 30fps as the planning convention unless the output pipeline requires otherwise.

For a 15-second film, target 5-8 major beats. For a 30-second film, target 8-12 major beats. Each beat should define:

• Start and end time or frame range
• Visual owner and authentic asset IDs
• Primary action
• Product or brand proof shown in the shot
• Copy and readable hold
• Color state
• Incoming and outgoing transition
• Motion intent: setup, anticipation, commitment, impact, brake, settle

A useful 15-second pattern is: brand hook, user intent or setup, product mechanism, capabilities or scenarios, output or proof, product payoff, final logo and CTA. Use 6-12 frame overlaps when outgoing motion naturally supplies the next shot.

STEP 6: Direct the motion language

Build intensity with control:

• Let product motion, cursor paths, UI flow, light, scrolling content, object edges, or matched geometry drive transitions
• Use 2-5 deliberate color states tied to meaning
• Keep one primary action per beat; delay secondary layers slightly
• Establish 2-3 high-energy peaks and quieter braking moments
• Preserve readable silhouettes, copy, and logo clear space
• Avoid fake HUDs, arbitrary glass cards, decorative text walls, unverified metrics, and identical easing everywhere

For AI products, include at least one readable chain such as: prompt -> planning -> parallel capabilities -> generated result -> proof. For physical or service products, show cause and effect from user action to concrete outcome.

STEP 7: Hard confirmation before generation
