AI Talking Head Best Practices

Production-ready guidelines for creating high-quality talking head videos at scale, from script writing to quality assurance and distribution.

Script Optimization

• 150 words per minute: AI TTS sounds most natural at this pace; plan script length accordingly
• Front-load key messages: Put the most important information in the first 30 seconds
• Use contractions: "You'll" instead of "you will" sounds more conversational
• Break into segments: Use multiple scenes rather than one long monologue
• Include SSML markers: Some platforms support Speech Synthesis Markup Language for precise control

Video Length Guidelines

Platform	Optimal Length	Max Recommended
Social media	30-60 seconds	90 seconds
Marketing	1-2 minutes	3 minutes
Training	3-5 minutes	10 minutes (with chapters)
Sales outreach	30-45 seconds	60 seconds

Quality Assurance Workflow

1. Script Review

   Have someone else read the script aloud before generating. Fix awkward phrasing and pronunciation issues.

2. Audio Preview

   Preview the TTS audio alone first. Check for mispronunciations, pacing, and tone.

3. Test Render

   Generate a short test clip (first 30 seconds) before rendering the full video.

4. Full Review

   Check lip sync, artifacts, audio quality, and timing across the entire video.

5. Stakeholder Approval

   Share for feedback and approval before publishing externally.

Scaling Production

• Templates: Create reusable video templates with consistent branding, intros, and outros
• API automation: Use platform APIs to generate videos programmatically from data sources
• Batch processing: Queue multiple videos for overnight rendering
• Content calendars: Plan and produce videos in batches rather than one-off
• Version control: Track script versions and video iterations systematically

Distribution and Analytics

• Export in platform-optimized formats (16:9 for YouTube, 9:16 for TikTok/Reels, 1:1 for LinkedIn)
• Add captions/subtitles for accessibility and silent autoplay
• Track engagement metrics: view duration, completion rate, click-through rate
• A/B test different avatars, scripts, and formats to optimize performance
