HappyHorse 1.1 Lip Sync Guide

Build HappyHorse 1.1 talking-head prompts for multilingual lip-sync with stable faces, short dialogue and controlled camera motion.

How this workflow works

For lip-sync shots, face stability matters more than decorative motion. Use a readable crop, restrained gestures and one concise spoken line so mouth motion remains the dominant synchronization task.

Step 1

Favor a stable face crop

Head-and-shoulders or medium framing gives the model enough facial detail without overloading the shot.

Step 2

Reduce competing motion

Avoid fast camera movement, complex hand choreography and multiple speakers unless the shot truly requires them.

Step 3

Keep speech duration realistic

Write a line that can be spoken naturally within the clip. Dense copy is more likely to create rushed or unstable mouth motion.

Prompt example

A practical starting structure

Head-and-shoulders shot of the same presenter from the reference image, locked camera, soft window light. She smiles slightly and says in Spanish, “Te enseño cómo funciona en menos de diez segundos.” Precise natural lip-sync, stable eyes and facial identity, restrained head movement.
