Synthesys Common Mistakes to Avoid
Mistake #1: Writing Long Scripts in One Scene
❌ Wrong: Putting a 5-minute script into a single scene and wondering why it looks stiff.
✅ Right: Split your script into shorter scenes of 30 to 60 seconds each for smoother rendering.
Mistake #2: Skipping Voice Preview
❌ Wrong: Picking a random voice and generating the full video without listening first.
✅ Right: Always preview 3 to 5 voices with your actual script before committing to one.
Mistake #3: Using Low-Quality Photos for Talking Photos
❌ Wrong: Uploading a blurry selfie or side-angle photo and getting weird lip movements.
✅ Right: Use a high-resolution, front-facing photo with even lighting for best results.
Synthesys Troubleshooting
Problem: Video Takes Too Long to Render
Cause: Your script is too long or you have too many scenes in one project.
Fix: Break your video into smaller segments of 1 to 2 minutes each and render them separately.
Problem: Avatar Lip-Sync Looks Unnatural
Cause: The script contains unusual words or abbreviations the AI can’t pronounce.
Fix: Spell out numbers and abbreviations, and add phonetic hints for unusual names.
Problem: Voice Clone Doesn’t Sound Like Me
Cause: Your recording sample was too short or had background noise.
Fix: Record a clean 5-minute sample in a quiet room with consistent volume.
📌 Note: If none of these fix your issue, contact Synthesys support at support@synthesys.io.
