Step-By-Step Guide to Create Talking Videos

Step 1: Access the Tool.

1. Navigate to Video Tools and select Lip Sync AI.
   
2. You’re now in Pollo AI’s AI video maker workspace—fully online, no install needed.
   

Step 2: Prepare Your Input Video

• Accepted formats: MP4 or MOV.
  
• Free-tier limits: 2–10 seconds or ~100 MB, 720p minimum resolution.
  
• Higher-tier credits support longer clips.
  
• Best practices:
  
  • Use stable, clearly lit footage.
    
  • Keep the speaker’s face fully visible and centered.
    
  • Use high-resolution video (at least 720p).

Step 3: Upload Video

• Click “Upload Video” or drag-and-drop into the workspace.
  
• Wait for confirmation that the video is processed.
  
• An embedded preview player will appear showing your clip.

Step 4: Add Audio Input

Pollo AI enables two simple ways to synchronize speech:

1. Text-to-Speech
   
   • Enter your script in the TTS box (up to 600 characters).
     
   • Choose voice avatar, set speech rate, emotions (e.g., happy, sad).
     
   • Preview the voice before finalizing.
     
2. Upload Audio File
   
   • Upload an existing audio clip (MP3, WAV, M4A, FLAC, etc., up to 20MB, <40 seconds).
     
   • Useful if you recorded voice or have a custom narration.

Step 5: Configure Lip Sync Settings

• Voice selection: Pick the ideal voice avatar from Pollo AI’s library.
  
• Speech speed + emotion: Adjust for natural or stylized delivery.
  
• Multi-speaker scenes: Optionally add additional voice-track syncs for dialogue.
  
• Visibility/copy protection: Set privacy and watermark options.

Step 6: Generate Preview

• Click Create to initiate lip sync processing.
  
• Processing completes within a few minutes, depending on duration.
  
• A preview is available in-browser—review lip sync accuracy and head movement alignment.

Advanced Tips & Techniques

Multi-Speaker Dialogue Scenes

• Upload multiple audio files or TTS scripts.
  
• Pollo AI supports syncing up to 10 distinct speech lines in one clip.
  
• Use face boxes to assign dialogue accurately.

Dynamic Head Movement Synchronization

• The AI still performs well even with angled faces or subtle head turn—ideal for natural scenes.

Non-Human Characters

• Characters with realistic face structure may work, but quality is best with human faces.

Sample Creative Use Cases

1. Educational Tutorials
   Create professional-looking instructor videos with clear lip syncing.
   
2. Product Demos
   Add narration to product walkthroughs using real audio.
   
3. Social Media Engagement

Why Pollo AI Stands Out

Pollo AI distinguishes itself in the AI video generator category by combining:

• Multi-engine flexibility: Choose Kling, Runway, Hailuo for lip sync.
  
• Motion and depth: Realistic head movement and emotional expression detection.
  
• All-in-one suite: Lip Sync works alongside other AI tools like face swap, dance, anime converters, and filters.
  
• SEO-ready design: Keywords like AI video generator, online, and free are embedded in both UI and content flow.
  
• Budget-friendly access: Generous free credits and tiered plans support diverse creator needs.
