Mechanism

How HappyHorse 1.1 works

HappyHorse renders from a prompt with an optional first frame and optional references, under a seed you can fix. The unusually wide aspect menu plus a stable seed is the combination that matters: one approved take can be re issued in every crop a campaign needs without becoming a different shot each time.

Questions

HappyHorse 1.1 FAQ

Which aspect ratios does it support?

Eight, from square through both portrait and landscape crops to ultrawide. The specs table on this page lists them exactly.

Can I reproduce a clip exactly?

Yes, by fixing the seed and keeping the prompt identical, which is what makes delivering one take in several crops realistic.

Does it take a last frame?

No, first frame only. Use the seed rather than a last frame to keep repeated runs consistent.

How many references?

Up to 4 per run, which is how you keep a product or a face steady across every crop.

Does it generate audio?

No, picture only, so what comes back is a clean plate for your own sound.
