# Scene: Copywriting / Script
|
||
|
||
## Scope
|
||
|
||
Broadcast scripts, product promotion copy, livestream scripts, presentation scripts, speeches, hosting scripts, short video scripts — any document where the goal is **spoken delivery**.
|
||
|
||
→ Placeholder convention & universal prohibitions — see `references/common-rules.md`
|
||
→ Font profile: **B (Visual)** — see `references/common-rules.md`
|
||
|
||

|
||
|
||
## 1. Core Principles
|
||
|
||
⚠️ **A broadcast script is NOT a report, NOT a spec sheet, NOT an encyclopedia.**
|
||
|
||
The goal is for the audience to **understand on first listen, remember key points, and take action.** Therefore:
|
||
|
||
1. **Highlight selling points, don't pile specs:** Each paragraph covers only 1–2 core points with relatable scenario descriptions
|
||
2. **Conversational tone:** Use "you" not "the user"; use natural speech, not corporate jargon
|
||
3. **Rhythm:** Alternate long and short sentences, insert pause markers, avoid wall-of-text paragraphs
|
||
4. **Length discipline:** ~250–300 words per minute of speech; a 5-minute script should not exceed 1500 words
|
||
5. **Information consistency:** All data, model numbers, prices must be consistent throughout — no self-contradiction
|
||

|
||
## 2. Document Structure
|
||
|
||
Completely different from reports:
|
||
|
||
```
|
||
Title (centered, short and punchy)
|
||
────────────────────
|
||
[Opening] ← Grab attention, 1–2 sentences
|
||
[Core Para 1] ← One selling point/opinion + scenario
|
||
[Core Para 2] ← One selling point/opinion + scenario
|
||
[Core Para 3] ← One selling point/opinion + scenario (max 3–5 paras)
|
||
[Closing] ← Summary + Call to Action (CTA)
|
||
────────────────────
|
||
[Notes] ← Supplementary info, data sources (optional, small grey text)
|
||
```
|
||
|
||
### Decisions
|
||
- **Cover:** ❌ Not needed
|
||
- **TOC:** ❌ Not needed
|
||
- **Header/footer:** Optional, minimal
|
||
- **Sections:** Single section sufficient
|
||
- **Line spacing:** `line: 400` (slightly larger than standard 1.5x for reading/marking ease)
|
||

||
|
||
## 3. Layout Standards
|
||
|
||
### Font Specifications
|
||
|
||
| Element | Font | Size | Style |
|
||
|---------|------|------|-------|
|
||
| Title | SimHei | 18pt (size:36) | Bold, centered |
|
||
| Section heading / highlight | SimHei | 14pt (size:28) | Bold |
|
||
| Body | Microsoft YaHei | 12pt (size:24) | Left-aligned |
|
||
| Rhythm markers | Microsoft YaHei | 10.5pt (size:21) | Grey 999999, italic |
|
||
| Notes | Microsoft YaHei | 10pt (size:20) | Grey 666666 |
|
||
|
||
### Paragraph Spacing
|
||
```js
|
||
// Generous spacing between paragraphs for reading/breathing pauses
|
||
spacing: { before: 200, after: 200, line: 400 }
|
||
// Larger gap between core sections
|
||
sectionGap: { before: 400, after: 200 }
|
||
```
|
||
|
||
### Key Point Highlighting
|
||
Use **bold** or **accent-colored text** to mark key selling points:
|
||
```js
|
||
new TextRun({ text: "Key selling point", bold: true, color: c(P.accent) })
|
||
```
|
||
|
||
### Rhythm Markers (optional)
|
||
Insert small grey markers where pauses, emphasis, or tone changes are needed:
|
||
```js
|
||
new Paragraph({ spacing: { before: 60, after: 60 },
|
||
children: [new TextRun({ text: "[Pause 2 sec]", size: 21, color: "999999", italics: true })] })
|
||
// Or inline: new TextRun({ text: " [emphasis] ", size: 18, color: "999999", italics: true })
|
||
```
|
||

||
## 4. Content Quality Rules
|
||
|
||
### Information Density Guide
|
||
|
||
| Script Type | Duration | Word Count | Core Paragraphs |
|
||
|-------------|----------|-----------|----------------|
|
||
| Short video | 30–60 sec | 150–300 | 1–2 |
|
||
| Product promotion | 2–3 min | 500–800 | 3–4 |
|
||
| Presentation / Speech | 5–10 min | 1200–2500 | 5–8 |
|
||
| Hosting script | Per agenda | Per segment | Per segment |
|
||
|
||
### Scene-Specific Prohibitions
|
||
|
||
1. **No spec dumping:** Do not list all product specifications in tables. Select 2–3 most persuasive data points and express them through scenarios
|
||
2. **No information contradiction:** Model numbers, prices, data appearing multiple times must be perfectly consistent
|
||
3. **No report tone:** No "in conclusion", "research indicates", "as mentioned above" — this is spoken word
|
||
4. **No lengthy citations:** Broadcast scripts do not need quotes, footnotes, or references
|
||
5. **No dense layout:** Paragraphs must have visible spacing — no screen-filling text walls
|
||
|
||
### Product Promotion Specific Rules
|
||
- **Opening:** Lead with pain point / scenario ("Does your washing machine still smell after a cycle?"), not self-introduction
|
||
- **Product intro:** Compare only 1–2 competitive dimensions at a time — not a full review
|
||
- **Price anchor:** State original/market price first, then discount price — create contrast
|
||
- **CTA:** Explicitly state the action ("Click the link below", "Type 1 in comments")
|
||

|
||
|
||
## 5. Palette
|
||
|
||
Broadcast scripts use clean, simple colors — no complex visual design needed:
|
||
|
||
```js
|
||
const P = {
|
||
primary: "#1A1A1A", // Title
|
||
body: "#333333", // Body
|
||
secondary: "#666666", // Notes
|
||
accent: "#E85D3A", // Key highlight (warm, energetic)
|
||
surface: "#FFF8F5", // Background (if needed)
|
||
};
|
||
```
|
||
|
||
---
|
||
|
||
## 6. Scene-Specific Quality Checks
|
||
|
||
In addition to universal checks (see `references/common-rules.md`):
|
||
|
||
- [ ] Total word count within target range (not exceeding)
|
||
- [ ] Each core paragraph has only 1–2 selling points (no dumping)
|
||
- [ ] Conversational tone present (not report/formal style)
|
||
- [ ] Information consistent throughout (model, price, data — no contradictions)
|
||
- [ ] Paragraph spacing sufficient (visually not crowded)
|
||
- [ ] Clear attention-grabbing opening + closing CTA
