Best Practices

Script Writing

• Keep it conversational: Write scripts as natural speech, not formal text
• Use contractions: "We're" instead of "We are" for natural delivery
• Break into segments: For longer content, split into multiple shorter clips
• Include pauses: Use commas and periods to indicate natural pauses
• Avoid jargon: Unless your audience expects technical terminology

Visual Quality

• High-resolution source: Use clear, well-lit portrait photos for lip-sync
• Front-facing angle: Best results with subjects looking at camera
• Neutral expression: Starting images work best with neutral or slight smile
• Clean background: Simpler backgrounds produce cleaner results

Audio Considerations

• Clear audio source: Use high-quality audio for lip-sync features
• Consistent volume: Normalize audio levels before processing
• Natural pace: Speech that's too fast may affect lip-sync quality

Brand Consistency

• Use session_id: Maintain consistency across multiple videos
• Document appearance: Keep notes on presenter descriptions for future use
• Standardize backgrounds: Use consistent settings for brand recognition

When creating talking head content, include these details in your prompt:

1. Presenter Appearance: Age, gender, attire, professional style
2. Script: The exact text to be spoken
3. Tone/Delivery: Professional, friendly, energetic, serious, etc.
4. Background: Office, studio, neutral, custom environment
5. Aspect Ratio: 16:9, 9:16, or 1:1 based on platform
6. Emotional Expression: Neutral, happy, serious, empathetic
7. Language: Specify language and accent if needed

Example Prompt Structure
