Use Material As Progress Clock

Use Material as Progress Clock — Heritage Craft Documentary Ad

Use this Skill when the user wants a heritage-craft documentary ad where the material's own appearance is the clock: a Miao silversmith forging an ornament through eight steps, with "silver-white" spreading from zero to everywhere as the film's time marker.

Core principle: lock the final piece to the reference, let the material's transformation (not effects) mark time, keep it a top-tier craft-brand birth record — not a tourism or heritage propaganda film.

The prompt follows the three-part H3 structure (reference locking → core concept → timecoded 8-step shot list) with subtitle-card rules, a restricted palette, and on-site-only sound design.

1. Trigger

• An intangible-heritage craft documentary ad
• A slow, elegant process documentary for a handmade product
• A "from nothing to finished object" brand film
• A craft piece where the material's transformation drives the narrative

Do not use this Skill when:

• The user wants a flashy national-style VFX show or a tourism promo
• The user wants a museum-style exhibition film
• No reference image of the finished piece exists

2. Inputs

• One reference image of the finished silver piece (@图片1) — locks form, proportion, silver surface color, chiseled pattern and overall temper. No added dragons/phoenixes/buddhas/text/decorations that don't exist.
• Packaging & workshop scenes are described in text (no reference images needed).
• Duration 15s, aspect 9:16, subtitle-card driven, on-site sound only.

3. Eight Steps (timecoded, 9:16)

1. 0–1.7s Main shot: dim Miao stilt-house workshop at night, one warm lamp lights only the hands; raw silver grains, dark crucible, repeatedly beaten silver mass; the hands beat/press/knead a soft blank. No silver-white yet. Subtitle: 第一道 · 锤银成坯.
2. 1.7–3.3s Extreme macro: the silver piece on anvil under hammer, thick block spreads into a thin even sheet; tight shot shows slight oxidation, fine hammer marks, finger pressure. Subtitle stays: 锤银成坯.
3. 3.3–5.0s Main shot: the chiseled sheet appears for the first time; the smith drops the first line of pattern — a small curling-cloud motif; the first faint warm reflection. Subtitle: 第二道 · 一錾起纹.
4. 5.0–6.8s Macro insert: chisel/press/push on the surface; sub-millimeter fine lines form low-relief motifs — curling clouds, tangled branches, ruyi. Subtitle stays: 一錾起纹.
5. 6.8–8.6s Main shot: most chiseling done; very slow push-in as the piece is rotated, light sweeps the dense pattern; still matte grey-white, no polish shine yet. Subtitle: 第三道 · 錾刻成纹.
6. 8.6–10.2s The film's most important audio+visual peak: extreme macro, a small clump of silver chips and solder trembling in the firelight; the smith draws solder to the seams with a torch; the moment it flows, silver-white appears en masse for the first time. Subtitle: 第四道 · 一火成器.
7. 10.2–11.7s Macro: a soft cloth wipes the surface; excess solder and oxidation are rubbed away and the sharp silver pattern emerges from dull grey — the second visual peak, an explicit "dull grey → bright silver-white" reveal. Subtitle: 第五道 · 银光醒来.
8. 11.7–13.8s Main + insert: finished piece on dark wood bench, hands rotate it slowly for inspection; then it is placed into the custom box (dark wood, warm beige soft lining, restrained no-logo lid) and the lid closes. Subtitles: 第六道 · 最后一眼 / 第七道 · 入盒.
9. 13.8–15s Final shot: cut to a minimal modern craft boutique; a hand places the finished piece at the center of a display and exits; the piece stays perfectly still in morning light. Subtitle: 第八道 · 上架. Tiny center text: 贵州苗族银饰 / 一锤成器. Final frame must read like high-end craft-brand static product photography.

4. Subtitle-Card Rules

Only one subtitle card: lower-third, horizontally centered, same position in every shot; restrained rounded rectangle, deep navy background, warm off-white text; two lines (thin step number + bold short action); it never moves/scales/fades/jumps — text changes only at edit points, always legible.

5. Palette & Light

Restricted to: aged silver-grey, dull silver-white, fire-warm orange, wood-dark brown, warm off-white, bright silver-white. Front half grey-brown dominant, middle warm orange grows, back half silver-white takes the visual center. Silver-white must come from real metal and real light — never glow VFX. No cyan-tech, neon, purple, cyberpunk, saturated national-style palettes.

6. Sound (on-site only, no music / narration / dialogue)

0–3.3s quiet dawn workshop (faint ambient, silver hitting the anvil, dense hammer strikes, hand-kneading friction); 3.3–8.6s even lower (chisel touching silver, small hammer taps, faint contact, wooden rack creak); 8.6–10.2s the film's key sound moment — all else dipped, only the torch's soft hiss, tiny crackles of flame licking silver, tools touching material, near-silence as the solder sets; 10.2–12.8s cloth rubbing silver, fine oxidation grit, the piece turning on the wooden rack; 12.8–15s paper folding, fabric friction, lid closing, then the shop: a "tock" as the piece meets the wood stand, then near-silence with faint room tone.

7. Generation

• Mode: I2VA with @图片1 as the finished-piece reference only — never used as the first frame unless explicitly requested.
• 15s, 9:16, native H3 audio (on-site sound only).
