Parameters
These fields come from the same schema we check every request against. Fields that are not listed are rejected.
promptstringRequiredWhat happens after the first frame, or between the first and last frame.
image_urlstringRequiredThe picture to start from.
last_image_urlstringOptionalOptional final frame, so the clip ends exactly where you want.
resolutionstringOptionalChanges the priceOutput size. Bigger sizes look sharper and cost more.
duration_secondsintegerOptionalChanges the priceHow long the clip runs. You pay per second.
generate_audiobooleanOptionalChanges the priceAdds sound made to match the picture: voices, ambience and effects.
shot_typestringOptionalsingle keeps one continuous shot; multi lets the model cut the clip into several shots.
seedintegerOptionalReuse the same number to get a repeatable result.

Responses, polling and callbacks
Every model works the same way: create a task, then poll it or wait for a callback.
Price it first
