How Bilibili differs from YouTube
Bilibili viewers tolerate more information: split comparisons, longer titles, and meme references are common. The underlying rule is the same though — the subject must read from afar and the title in under 3 seconds.
Three high-CTR patterns
1. Comparison
Left/right split showing "before / after" or "expectation / reality" — built-in conflict drives clicks.
2. Face + big type
Creator close-up with a 4–8 character headline; great for knowledge and lifestyle content.
3. Scene suspense
A frame that makes viewers ask "what happened here?", paired with a question headline; great for documentary and review formats.
The AI workflow
- Pick the "Video thumbnail" scene at 16:9.
- Describe the pattern and emotion, e.g. "knowledge-zone cover, surprised host on the left, big title zone on the right, high contrast".
- Add the headline with text overlays — large type, 8 characters max.
