Exact author/compute contracts and package-owned author Surfaces for MiniMax H3 video generation.
Text, frame-guided and subject-reference modes are separate Surfaces rather than one dynamic port mode. Each produces an ordinary video Artifact. This package owns request semantics and validation only; Provider calls, credentials, retries and queueing belong to a Runtime Endpoint selected in the Runtime Profile.
<h3:TextVideo id="idea" prompt={prompt} duration="6" resolution="768P" aspect-ratio="9:16"/>
<h3:FrameVideo id="motion" prompt={motionPrompt} duration="6" resolution="2K"
first-frame={cover.image} last-frame={ending.image}/>
<h3:ReferenceVideo id="montage" prompt={montagePrompt} duration="8" resolution="768P" aspect-ratio="9:16">
<h3:Reference image={person.image}/>
<h3:Reference video={gesture.video}/>
</h3:ReferenceVideo>The Surface makes every prompt/media dependency an explicit graph edge and leaves execution to a Provider.
FrameVideo accepts a first frame, a last frame, or both; either frame is an ordinary image Artifact edge.
