HappyHorse 1.1 vs Seedance 2.5 for Talking heads
Talking-head generation benefits from a stable face reference, restrained motion and synchronized speech. Native audio and explicit lip-sync or avatar capabilities matter more than cinematic effects.

Run the same brief, not two different demos
Use one stable face reference and a short speech line. Keep duration, aspect ratio and creative intent identical across models, then judge only the constraints that matter for talking heads.
- Use identical source media, wording, duration and aspect ratio.
- Keep the same number of attempts for both models.
- Change only syntax that is required by the target model; keep creative intent constant.
- Score each output against the workflow constraints, then compare retry-adjusted cost.
Success signals for talking heads
- Face shape and gaze remain stable during speech rather than morphing between phrases.
- Mouth motion follows the intended speech rhythm without exaggerated or delayed articulation.
- Head and camera motion stay restrained enough that speech remains the visual focus.
