| description | Use when planning promotional videos for software products - guides through style selection, content structure, script writing, and title/thumbnail design. Triggers on "视频宣传", "promotional video", "B站视频", "YouTube video", "产品演示视频", or video marketing requests. |
A data-driven workflow for planning software product promotional videos targeting B站 and YouTube. Based on creator best practices and platform algorithm insights.
| Metric | Data | Source |
|---|---|---|
| First 3 seconds | Verdict window - stay or leave | TechGig research |
| Hook window | 5-10 seconds to capture or lose viewer | Retention studies |
| Thumbnail decision | 10-20 milliseconds | Eye-tracking research |
| Face in thumbnail | 11x more noticeable | YouTube data |
| Silent viewing | 83% watch with sound off | Platform analytics |
| Caption impact | 80% more likely to finish with captions | Accessibility studies |
| Long-tail views | 40% of views happen after 30 days | Creator analytics |
| Pattern interrupt | +23% retention rate | A/B testing |
| Open loops | +32% watch time | Content experiments |
| Short demo sweet spot | 30-60 seconds for product demos | Product Hunt data |
Ask the user:
| Style | Best For | Characteristics |
|---|---|---|
| Screen Recording + Narration | Developer tools, complex features | Direct, efficient, shows real usage |
| Motion Graphics | Consumer apps, brand awareness | Polished, engaging, highlights benefits |
| Scenario Story | Lifestyle apps, emotional appeal | Relatable, shows transformation |
| Hybrid | Feature-rich products | Combines demo with storytelling |
Platform DNA:
| Video Type | B站 | YouTube | Notes |
|---|---|---|---|
| Quick Demo | 3-5 min | 2-3 min | Single feature, fast value |
| Full Introduction | 8-12 min | 5-8 min | Complete overview |
| Tutorial | 10-15 min | 8-12 min | Step-by-step guide |
| Story-driven | 5-8 min | 3-5 min | Emotional narrative |
| Shorts/竖屏 | <3 min | <60 sec | Hook → Value → CTA |
Golden rule: Content density > raw length. Cut ruthlessly.
The first 3 seconds are a verdict, not an introduction.
The viewer's brain asks three instant questions:
If any answer is "no", the thumb wins. You have 5-10 seconds max to prove value.
Hook Types:
| Type | Formula | Example |
|---|---|---|
| Negative Bias | "Stop doing X if you want Y" | "别再手动加字幕了，如果你想..." |
| Story Tease | "I almost lost everything when..." | "我差点因为字幕问题丢掉这个项目..." |
| Bold Claim | "Everything you know about X is wrong" | "你对字幕工具的认知可能完全错了" |
| Result First | Show impressive outcome immediately | [展示完美字幕效果] "这只用了3分钟" |
| Problem Pain | Relatable frustration | "字幕翻译要花3小时？我懂那种痛苦" |
Micro-Hooks (信号，不是句子):
Micro-hooks are signals, not sentences. They trigger instant attention:
Hook Techniques:
Anti-patterns to avoid:
AIDA Framework for Software:
1. ATTENTION (0:00-0:30) - THE HOOK
- Pattern interrupt or bold claim
- Show the "aha moment" immediately
- State the core benefit
2. INTEREST (0:30-2:00) - THE PROMISE
- Product introduction (brief)
- Core value proposition
- Quick demo of main feature
- "By the end of this video, you'll be able to..."
3. DESIRE (2:00-6:00) - THE PROOF
- Feature walkthrough (3-5 features max)
- Each feature: Pain → Solution → Demo
- Social proof if available
- Address common objections
4. ACTION (last 30s) - THE ASK
- Clear, specific CTA
- Links and resources
- Engagement ask (platform-specific)
Alternative: PAS Framework (shorter videos)
Problem (0:00-0:30) - Agitate the pain point
Agitate (0:30-1:30) - Make it worse, show consequences
Solution (1:30-end) - Your product as the hero
Script Template:
## [Section Name] (MM:SS-MM:SS)
**画面**: [What appears on screen - be specific]
**旁白**: [Narration text - conversational, short sentences]
**字幕**: [On-screen text/captions - 83% watch muted!]
**BGM**: [Music mood: upbeat/calm/dramatic/none]
**视觉效果**: [Zoom, highlight, transition notes]
[PAUSE] - Mark breathing points
[PATTERN BREAK] - Mark visual/audio changes

Script Principles:
Voice Guidelines:
Thumbnail Design (10-20ms to decide):
| Element | Guideline |
|---|---|
| Face | Include if possible (11x more noticeable) |
| Text | 3 words MAX, large font, readable at 100px |
| Contrast | High contrast colors, test at small size |
| Emotion | Curiosity, surprise, or transformation |
| Consistency | Series recognition for returning viewers |
Title Formulas:
| Formula | B站 Example | YouTube Example |
|---|---|---|
| [Result] + [Tool] | "10分钟生成专业字幕 - MioSub教程" | "Professional Subtitles in 10 Minutes" |
| [Problem] → [Solution] | "字幕翻译太慢？AI帮你搞定" | "Slow Subtitle Translation? Try This" |
| [Number] + [Benefit] | "5个让效率翻倍的技巧" | "5 Tips to Double Your Speed" |
| [Comparison] | "MioSub vs 传统工具：实测对比" | "MioSub vs Traditional Tools: Tested" |
| [How-to] | "如何用AI自动生成双语字幕" | "How to Auto-Generate Bilingual Subs" |
Title Rules:
Provide the user with:
"Knowing who watched, how long they watched, and where they dropped off makes the demo a real growth lever, not just a nice-to-have."
After publishing, track:
| Metric | What It Tells You | Action |
|---|---|---|
| Drop-off points | Where viewers lose interest | Tighten that section |
| Completion rate | Overall engagement | Adjust length/pacing |
| Click-through rate | Thumbnail/title effectiveness | A/B test variations |
| Replay sections | What viewers found valuable | Double down on that content |
| Comments/弹幕 | Audience questions/confusion | Address in next video |
Iteration cycle:
MrBeast's Core Insight:
"If your motivation for grinding is so you can buy a nice car and maybe buy a nice house, you're not going to be one of the greats."
Content compounds over time:
One Asset, Multiple Channels (复用策略):
The same demo video works across:
Create once, distribute everywhere. Adapt length/format per channel.
Cross-platform workflow:
| Mistake | Fix |
|---|---|
| Weak hook | Show result or pain in first 3 seconds |
| No captions | 83% watch muted - captions are mandatory |
| Feature dump | Focus on 3-5 benefits, not all features |
| Generic thumbnail | Face + 3 words + high contrast |
| Same for both platforms | Adapt pacing, style, and metadata |
| Marketing speak | Talk like a builder, be honest about tradeoffs |
| Ignoring long-tail | Content keeps working for months - invest in quality |
| No tracking | Can't improve what you don't measure |
| Cluttered background | Distracts before message lands - clean your frame |
| One-and-done | Iterate based on drop-off data |
