What Business Problems Does This Tool Solve
Pain points for content creators, marketers, self-media operators, and enterprise social media teams: Recording a 1-hour video takes 5 hours to edit, write copy, and adapt for multiple platforms.
Typical Scenarios:
- Knowledge bloggers recording podcasts → Need to cut into 3-5 short videos for Xiaohongshu/Douyin
- Training instructors recording courses → Need to create clips for student review
- Merchant livestream replays → Need to edit highlight clips for secondary distribution

The Value of This Tool: Upload and get your video ready. Generate a multi-platform short video package ready for publishing in just 5 minutes.
Business Logic and Underlying Workflow
Phase 1: Multimodal Analysis
- Audio → Transcription + Emotion curve + Keyword density
- Video → Shot transition detection + Visual change points
- Subtitles → OCR + Keywords + Key sentences
Phase 2: Highlight Identification
- Three-dimensional fusion scoring (Emotion peaks + Visual changes + Key sentences)
- Output 1-10 highlight clips (with timestamps + reasons)
Phase 3: Smart Editing
- Auto-segmentation + Transitions + BGM recommendations
- Generate "first 3-second hook" versions (specifically optimized for short video algorithms)
Phase 4: Multi-Platform Copywriting
- Xiaohongshu: Clickbait titles + Emojis + Hashtags + 500-word body
- Douyin: Hook titles + 60-character intro + 8-12 hashtags
- WeChat Channels: Approachable titles + Long-form body + 3-5 hashtags
