What not to assume.
Every request has to fit the HappyHorse 1.1 envelope of 3–15s and 720p / 1080p; values outside it are refused before rendering.
HappyHorse 1.1 always renders its own audio; the catalog lists no silent HappyHorse 1.1 policy.
Motion can drift in identity, geometry, small text, logos and continuity, so HappyHorse 1.1 output still needs review before publishing.
A HappyHorse 1.1 request is asynchronous: a pending job is not a finished clip.
What the HappyHorse 1.1 envelope allows
HappyHorse 1.1 currently lists 3–15s durations, 720p / 1080p output and 16:9 / 9:16 / 1:1 / 4:3 / 3:4 / 4:5 / 5:4 / 9:21 / 21:9 aspect ratios. Length is a free range from 3 to 15 seconds, so pacing is set by the request rather than by the model.
Choosing the workflow
HappyHorse 1.1 starts from a prompt alone or from a reference image, so the first decision is which of the two carries the framing. Up to 9 reference frames are accepted per request, so more than one source frame can carry the look. Audio is rendered natively with the clip rather than added later.
How a request runs
Vizify inspects the selected policy before it sends the request, so a value outside the published envelope is refused rather than quietly adjusted. Video generation is asynchronous: a pending job is not a completed artifact, and the returned clip still needs a review pass for identity, geometry, small text and continuity before it is published.
