Recording Guidelines

What to Record

For HeyGen (2-5 minutes):

Script content variety:
- Read a passage naturally
- Count from 1-100
- Read tongue twisters
- Explain something casually

For Synthesia (10-15 minutes):

Multiple segments:
- Neutral talking
- Explaining content
- Different expressions (happy, serious)
- Various head positions

How to Perform

Eye contact:

• Look directly at camera lens
• Use a teleprompter app (place near lens)
• Avoid reading from paper off-camera

Facial expression:

• Natural, slightly positive expression
• Don't be too animated
• Don't be too stiff
• Think "professional news anchor"

Head movement:

• Subtle, natural movements
• Don't nod too much
• Don't be perfectly still
• Keep within frame

Speech:

• Natural pace (not too fast)
• Clear enunciation
• Consistent volume
• Brief pauses between sentences

Common Mistakes

Too much movement: Creates sync issues and artifacts

Unnatural stiffness: Avatar looks robotic

Looking away: Breaks eye contact illusion

Inconsistent lighting: Face lighting changes cause glitches

Poor audio: Background noise trains into the model
