Minimalist Product Ad Generator

Use this Skill to guide non-professional users through a flow-style workflow that creates a minimalist product advertising video for e-commerce promotion and product launches. The target users are e-commerce sellers, small brand owners, indie creators, and individual sellers; the user should provide at least one product image or related asset.

The core principle is: confirm assets and brief first, build product facts and a product narrative spine, lock product visuals with independent anchor photos, control video with a precise beat storyboard, then finish the film with native audio or music-based editing. This Skill no longer defaults to a 4-panel anchor sheet, because video models may reproduce the panel layout. By default, it uses three separate anchor photos plus one precise beat text storyboard as the video control system.

Start Gate

Every time this Skill is triggered, run a complete but lightweight start gate before any analysis, copywriting, anchor generation, or video generation. Confirm only the information required for production. Do not ask about music here; music is handled later in the music step.

The start gate must confirm all of the following in one pass:

  1. Product images and related materials
    • Ask the user to upload product images and related materials, such as product photos, packaging images, renders, detail shots, existing video assets, or visual references.
    • If the current message or current canvas / session already contains materials, state that materials have been detected. Do not ask the user to upload again; only confirm whether to use the current materials.
    • If there are multiple candidate materials and their roles are unclear, ask which one should be the main product image.
  2. Product variant status
    • Confirm whether this is a single variant or multiple variants / colors / models.
    • If there are multiple variants, confirm which one is the main variant.
    • If the user does not specify, the agent may recommend one based on the product image, but the later storyboard must still write the concrete color or variant name.
  3. Target duration
    • 5s / 10s / 15s, with 10s as the recommended default.
  4. Aspect ratio
    • 16:9 / 9:16 / 1:1 / 4:3 / 3:4 / match reference image.
    • Once selected, the anchor sheet, video, and final delivery must strictly keep this ratio.
  5. Apple-style template
    • White-tech / dark rim light / brand color field / light lifestyle scene.
  6. In-frame copy
    • User-provided copy, or agent-generated Apple-style English copy.
  7. Video model strategy
    • Default model is MiniMax-H3, because it often produces cleaner Apple-like product close-ups, negative space, and premium product-film camera language.
    • Do not ask the user to choose a video model during the start gate. Show “default model: MiniMax-H3” as part of the adopted start-gate result.
    • If the user explicitly asks for another model, follow the user's model choice after capability checking.
    • Seedance is only a backup when the user explicitly wants stronger multi-shot execution, asks for Seedance, or accepts a fallback after H3 fails or cannot satisfy the requested structure.

Start gate is mandatory. If the user has already uploaded product material, only skip the upload request; do not skip the rest of the start gate. The agent must still confirm product variant status, target duration, aspect ratio, Apple-style template, and in-frame copy mode in one pass before analysis, anchor generation, storyboard, or video generation. The video model is not a start-gate question: use MiniMax-H3 by default and display it in the completed start-gate result. If the user says “you decide / just do it,” the agent may choose recommended defaults for the remaining fields, but must still display the adopted choices as the completed start-gate result before continuing.

Operating Principles

  1. Independent anchor photos are the default visual control system
    • Generate three separate anchor photos by default, not one 4-panel sheet, because video models may copy panel layouts into the final film.
    • The three anchor photos usually cover: hero / striking main view, material or functional detail, and final copy composition.
    • Do not create a separate structure-action anchor when it overlaps with the hero view. Merge structure / action cues into the material-detail anchor unless the product truly needs a distinct mechanism reference.
    • Each anchor photo must be a complete standalone product photo. Do not create grid layouts, split screens, collage boards, framed panels, product walls, or storyboard sheets.
    • The precise beat storyboard determines the actual shot order, action, and text behavior. Do not use anchor photos as direct shot replacements.
  2. In-frame copy must appear as integrated video motion, not a subtitle fallback
    • Text in the copy anchor photo is only a reference for font, position, single-line layout, and two-part color treatment. It does not mean the whole video can use only that one copy line.
    • The precise beat storyboard may define multiple short English copy lines across shots. Each line must be 3-5 English words, single-line, readable, and follow the two-part color rule: in white-tech style the first half uses black or dark gray, in dark rim-light style the first half may use white, and the second half always uses the specific product color. Do not use isolated 1-2 word feature labels.
    • Video generation must include the storyboard copy inside the frame.
    • The copy does not need to appear in every shot. If the video model tends to make typography mistakes, reduce copy frequency proactively. For a 10-second film, usually keep only one mid-film copy moment plus one final copy moment; do not put text in every shot. The final shot must include one stable single-line copy.
    • By default, ask the video model to generate in-frame typography and its timing directly. Do not silently degrade text into post-production subtitles or reserve empty space for later overlay. Use post-production fallback only when the user explicitly asks for it or when integrated video typography fails and the user accepts a fallback.
  3. Product body color is a hard fidelity constraint
    • Apple-style means clean composition, premium light, restrained motion, and negative space; it does not mean turning the product itself white, silver, or AirPods-like.
    • The product's original body color, accent color, material tint, and visible finish from the user's image must be preserved in all anchor photos and videos.
    • Only the background, lighting environment, and composition may shift toward the selected Apple-style template. Never recolor the product body unless the user explicitly asks.
    • The final copy emphasis color must come from the real product main color, not from a generic silver / white Apple palette.
  4. Every product needs a product-specific narrative
    • Do not reuse a fixed earbud template or write vague phrases like “product state changes.”
    • The storyboard must be based on product category, form, material, structure, and visible actions.
    • Product motion must be visual and concrete, such as “the lid opens 30 degrees and inner reflection appears,” or “the crown rotates while a highlight slides along the edge.”
  5. Progress must be visible
    • After each step, show what was produced and what decision is needed next.
    • Do not auto-run the entire pipeline without user confirmation.

Typography Rules

STEP 1: Asset Check and Product Fact Summary

If no product material is available, ask the user to upload it. If material is already available, use it and analyze:

If the image quality is not usable, stop and give concrete reshoot advice.

Output a short product fact summary:

STEP 2: Confirm the Production Brief

Turn the start gate answers into an executable production brief. Do not ask again for parameters that have already been confirmed. The brief drives the narrative spine, copy, anchor sheet, and storyboard.

The production brief must include:

Multi-variant product rules:

STEP 3: Choose a Product Narrative Spine

Before copywriting and anchor generation, choose a lightweight product narrative spine. Do not use a broad corporate brand-film structure; this Skill focuses on short Apple-style films for physical products.

If the user has not selected a direction, offer 2-3 concise directions, recommend one, and continue after confirmation. If the user says “you decide,” use the recommended one.

Recommended spines:

  1. Product Launch (default recommendation)
    • Negative-space opening → main variant establishes hero view → material / structure detail → natural product action → variants or color relation → full-copy closing.
    • Good for earbuds, watches, digital accessories, small appliances, fragrance devices, etc.
  2. Feature Touch
    • Product stillness → interaction trigger → feature action → detail magnification → result / feeling → closing frame.
    • Good for products with clear opening, rotation, magnetic snap, light change, screen, folding, mist, or similar actions.
  3. Color Family
    • Main variant appears alone → supporting variants slide in lightly → color order forms → material and structure stay unified → full set closes → copy lands.
    • Good for multi-color, multi-variant, or multi-model products.

Output one sentence describing the selected narrative spine, for example:

This film uses the Color Family spine: the purple main variant establishes the hero view, other colors enter as supporting layers, and the full product set closes with the English copy.

STEP 4: Direct the Motion Language

Before copywriting and anchor generation, define the motion language of the film. This step does not generate assets; it defines motion intensity, transition logic, and rhythm peaks for the later storyboard.

Rules:

  1. Transitions are driven by real product or visual elements
    • Prefer product edges, material highlights, opening / rotation / snapping / sliding actions, geometric changes in variant arrangement, color entry and exit, matched camera direction, or matched product silhouette.
    • Do not use meaningless white flashes, abstract particles, random light effects, or random cuts to fake premium motion.
  2. One main action per beat
    • Secondary elements should appear with slight delay and should not compete for attention at the same time.
    • Examples: product enters first, then text appears; main variant stabilizes first, then supporting variants slide in; material highlight sweeps first, then text motion begins.
  3. Set strong and quiet moments
    • 5s film: 1 small peak + 1 stable closing.
    • 10s film: 1-2 peaks + 1-2 braking moments.
    • 15s film: 2-3 peaks + 2 quiet braking moments.
    • Peaks may be product action completion, variant entrance, second-half copy reveal, or full-product closing.
    • Braking moments may be material-detail pause, readable copy hold, or final frame hold.
  4. Keep safe space clear
    • Product silhouette remains clear, single-line copy stays readable, and the main variant is not blocked.
    • Add a logo only when the user provides one. Do not generate a fake logo.
  5. Avoid fake tech decoration, mirrored white stages, and empty openings
    • Avoid fake technology interfaces, meaningless glass cards, decorative text walls, unconfirmed metrics, random particles and stacked light effects, one identical easing style across the whole film, and full-screen product walls.
    • White-tech style is not a mirrored white stage and not dead flat white lighting. Do not place the product on reflective floors, glass tables, or cheap studio mirror surfaces.
    • Apple-style white space should be a simple white background; impact comes from striking product angles, real product actions, camera rhythm, and negative-space composition, not from mirror reflections or waiting on empty frames.
    • The opening must not be empty dead time. It should quickly reveal an attractive product action or angle, such as the product rotating smoothly out of its own structure, emerging from an opening mechanism, sliding along its silhouette, or being revealed by an edge highlight. The exact action must be inferred from the current product form, not hardcoded to earbuds.

Output one short “motion language” statement, for example:

This film uses product-edge highlights and the purple main variant sliding motion to drive transitions. The main peaks are variant entrance and full-copy landing, with a stable final hold for the product and copy.

STEP 5: Generate or Confirm Apple-style English Copy

Before generating the text anchor and storyboard, obtain a final English copy line for the frame.

Rules:

  1. Analyze product category, usage feeling, and narrative spine.
  2. Generate 2-3 Apple-style English options, each 3-5 words.
  3. Do not use fixed templates or fixed slogans; infer new copy for every product.
  4. Avoid promotional language.
  5. If the user already has copy, prioritize it. Chinese copy must be localized into concise English.

After the user confirms the copy, proceed to anchor generation. If the user says “you decide,” choose the recommended copy and continue.

STEP 6: Generate Three Independent Product Anchor Photos

Generate three independent anchor photos in the same aspect ratio and resolution as the user-selected video setting. They must be three separate image outputs, not one combined 3-panel or 4-panel sheet. Background follows the selected style, and all three photos must share unified light, shadow, grade, and background language while remaining standalone product photos.

Anchor photo roles:

Multi-variant handling:

Final copy anchor typography rules:

Show the three independent anchor photos and ask the user to approve, edit, or regenerate a specific photo before proceeding to the precise beat storyboard.

STEP 7: Precise Beat and Text Storyboard Table

Before generating any video clip, create and read back a precise beat text storyboard table. It is not artwork; it is the execution table for the video model.

The storyboard table must be organized as “User Choice Statement → Beat Content → Principles.”

User Choice Statement

Write the confirmed style, aspect ratio, duration, narrative spine, main variant, product main color, variant strategy, and copy. Example:

White-tech style, 16:9, 10 seconds, Color Family spine, purple as the main variant, other colors as supporting layers, copy: Color Meets Sound.

Beat Content Table

Recommended columns:

Time rangeShotShot purposeVisual leadVisual / camera moveVariant stateCopyText colorText effectTransition / continuityRhythm intent

Table rules:

Rhythm intent vocabulary: setup, establish, prepare, impact, brake, settle.

Principles

  1. Keep core text on a single line.
  2. At any moment, only one single-line English copy line may appear; forbid two text rows, upper/lower line splits, title + subtitle pairs, or multiple text blocks at the same time.
  3. Use exactly two text colors: black or white + confirmed specific product color.
  4. The text must appear inside the video; do not rely only on post-production fallback.
  5. Shot continuity = element continuity + motion continuity + form continuity.
  6. Smoothness = easing + no awkward timing + seamless entrances and exits.
  7. Total pacing follows the user-selected duration.
  8. Text motion must be visible: the first half fades in or slides in subtly first, then the second half fades in or slides in subtly later. When the second half appears, the first half shifts subtly within the same line to make room. Do not make the text completely static, and do not split it into upper and lower rows.
  9. If the style is confirmed, the table must strictly follow that style.

After the user confirms the storyboard table, proceed to video generation.

STEP 8: Video Generation

Generate video directly from the confirmed three independent anchor photos + precise beat text storyboard table. Video style, background, lighting, mood, and pacing follow the selected style. Aspect ratio and size must strictly follow the user-selected setting; if the user chose 16:9, generate 16:9 and do not auto-change to another ratio.

Video reference rules:

The video prompt must include:

STEP 9: music-2.6 Tech BGM

Video generation defaults to MiniMax-H3 native audio first, and the Apple-style tech BGM direction below should be written into the video prompt. If H3's native music is unpleasant, too loud, too weak, out of sync, or the user asks for new music, use music-2.6 to generate a longer standalone instrumental BGM and replace the video audio track. Do not default to ElevenLabs; use ElevenLabs only when the user explicitly requires a strict target duration, and follow the fee-confirmation rule.

Default music direction:

Around 100 BPM, fast tech feeling, block chords, pluck and airy noise bed, kick + sub-bass + sine sweep, wooden percussion, sudden cut-off, within 0.5s everything stops, leaving only the pluck tail to decay.

Extended interpretation:

STEP 10: Music Analysis, Beat-synced Editing, and Delivery Verification

Before final delivery, edit or assemble based on music analysis. Do not simply lay music under the video.

Music analysis:

Audio assembly rules:

Pre-delivery verification:

Delivery includes:

Failure Handling
