The short answer

Open Settings > Twin Mode > Fidelity. If voice or visual score dropped more than 3 points week over week, the most common cause is a vendor model update. Wait 24 to 48 hours; ENCORE auto-recalibrates. If it persists, re-enroll.

Three causes

  1. Vendor model update. Hedra or HeyGen pushed a new model version. ENCORE adapts but the first 24 to 48 hours can show a temporary dip. No action needed.

  2. You shipped renders outside your normal context. If your last 10 renders were all in unusual settings (e.g., extreme close-up, low light, rapid motion), the system's fidelity score can dip because the audience signal data is mixed. Solution: ship a few renders in your standard format. Scores recover.

  3. Your face or voice changed. New haircut, new glasses, gained or lost noticeable weight, recovering from cold. The twin was trained on your prior look/voice. Solution: re-enroll (free for the first 60 days post-initial).

How to re-enroll

Settings > Twin Mode > Re-enroll. Same 5-minute flow as the initial enrollment. The system blends your old training with the new, preserving render history.

When to file a ticket

If fidelity has dropped more than 5 points week over week and stays low for 7+ days, file a ticket. We can investigate vendor-side issues.
