FAQs

Common questions about Happyhorse models and workflows.

What is HappyHorse?

What makes HappyHorse-1.0 different from other AI video models?

HappyHorse-1.0 generates audio — including dialogue, ambient sound, and Foley — natively alongside the video in the same forward pass. Most other models either skip audio or add it in a separate post-processing step, which can result in timing mismatches. HappyHorse-1.0 also supports multilingual lip-sync across 7 languages at the phoneme level.

What resolutions and durations does HappyHorse-1.0 support?

Can I generate videos without audio?

Yes. Audio generation is optional — you can toggle it off in the settings if you only need the video output.

Is HappyHorse-1.0 free to use?

You can try HappyHorse-1.0 with free credits after signing up. For unlimited generations or higher resolutions, a paid subscription plan is required.
