Pro Tips for Viral TikTok Subtitles
1. Use Word-by-Word Highlighting
Karaoke-style highlighting keeps viewers engaged. Their eyes follow the text, increasing watch time.
2. Position Subtitles Correctly
Place captions in the lower third of the screen—above the TikTok UI elements but below the speaker's face.
3. Match Font to Content
- Educational: Clean, bold fonts
- Entertainment: Playful, animated fonts
- Business: Professional, minimal fonts
4. Keep Text Readable
Maximum 2 lines on screen. Use high contrast colors. Avoid thin fonts.
5. Add Strategic Emojis
Place emojis at emotional peaks—laughs, surprises, key points. Don't overdo it (3-5 per 30 seconds).
Common Mistakes to Avoid
- ❌ Too much text: Keep it to 2 lines max
- ❌ Wrong timing: Subtitles should sync perfectly with speech
- ❌ Low contrast: White text on light backgrounds is unreadable
- ❌ Covering faces: Don't block the speaker
- ❌ Ignoring accuracy: Always review AI transcriptions
