@hypit/seedance-kits

Data-only authoring Kits for recurring Seedance semantics. They are TextTemplate source modules, not model wrappers, Providers or new execution nodes.

This package has no activation and no Runtime dependency. Running npm run pack:independent -- packages/seedance-kits preserves the ordinary package exports, the SVS files and their documentation; projects select its npm release through their package manager and lockfile.

The official Hypit Distribution currently obtains this data package as a default npm dependency; it is not copied into the root tarball and does not share the root package's release cadence.

Import a selected public Source from the installed package, for example @hypit/seedance-kits/speaker. The package manager or active Distribution owns the installed version; Source Closure reads that Source and its relative dependencies without copying it into the video project or reaching through a physical ../../packages/... path.

Each Kit is rendered by the domain-neutral text:Render Surface. Its Text output then feeds one of the three low-level @hypit/seedance invocation modes. Reference media and duration remain ordinary explicit graph edges:

<import as="text" from="@hypit/text@1"/>
<import as="seedance" from="@hypit/seedance@1"/>
<import as="broll-kit" source="@hypit/seedance-kits/broll"/>

<text:Render id="broll-prompt" template={broll-kit.broll-v1} recipe={recipes.broll}>
  <text:Set name="story" text={copy.broll}/>
</text:Render>

<seedance:ReferenceVideo id="broll" model="mini" prompt={broll-prompt}
  duration="5" resolution="720p" aspect-ratio="9:16">
  <seedance:Reference image={scene} person-reference="false"/>
  <seedance:Reference image={product} person-reference="false"/>
</seedance:ReferenceVideo>

Speaker uses the same graph vocabulary. The Kit assumes @image1 is the visible person and @audio1 is the voice-timbre reference; it owns no media counting or generation wrapper:

<import as="speaker-kit" source="@hypit/seedance-kits/speaker"/>

<text:Render id="hook-prompt"
  template={speaker-kit.speaker-v1}
  recipe={recipes.speaker.host}>
  <text:Set name="dialogue" text={story.segment.hook.dialogue}/>
  <text:Set name="action" text={hook-action}/>
</text:Render>

<seedance:ReferenceVideo id="hook-take" model="mini"
  prompt={hook-prompt} duration="8"
  resolution="720p" aspect-ratio="9:16" generate-audio="true">
  <seedance:Reference image={presenter} person-reference="true"/>
  <seedance:Reference audio={voice}/>
</seedance:ReferenceVideo>

Choose a template

Each import below has the prefix @hypit/seedance-kits/. The selected Source exports the listed template id. Its linked .svs file owns the exact fixed wording, default choices and allowed values.

| Import suffix / template | Intended relationship and media references | Text slots | | --- | --- | --- | | speaker / speaker-v1 | One visible speaker: @image1 is the character-and-scene view; @audio1 is that speaker's voice. | Required dialogue; optional action | | broll / broll-v1 | A silent visual micro-story; images appear in authored reference order, with their roles explained in the story. | Required story | | podcast / podcast-v1 | Two fixed views: images 1/2 show A/B, and audio 1/2 supplies their corresponding voices. | Required dialogue; optional action | | call / call-v1 | Image 1 shows A in the main tile and B in the inset; image 2 reverses them. Both are live views, with audio 1/2 for A/B. | Required dialogue; optional action | | street-interview / street-interview-v1 | Images 1/2/3 are interviewer A, guest B and shared street setups; audio 1/2 is A/B. A holds the microphone. | Required dialogue; optional action | | motion-reference / motion-reference-v1 | Image 1 supplies the subject; video 1 supplies body motion, gestures and pose dynamics. | Optional direction | | camera-reference / camera-reference-v1 | Image 1 supplies the subject; video 1 supplies camera framing, lens, movement and photographic rhythm. | Optional direction |

For example, source="@hypit/seedance-kits/call" imported as kit exposes kit.call-v1. Text slots use text:Set; scalar Recipe choices use the selected template's named axes. Reading the template reveals what each choice actually asks the generator to do. Rendering the Text Output as a Run Target lets an author inspect the assembled prompt without generating media.

Speaker, B-roll, Podcast, Call and Street Interview expose prompt choices through their Text Templates. The examples above use author-chosen literal durations. Measure adopted speech with hypit estimate first, then choose a duration within the selected model's declared range; there is no duration-estimation node on the generation route.

Recipe, dialogue and action

The Recipe carries recurring choices exposed by the selected template. dialogue receives the Script Segment's .dialogue Text, retaining pronunciation and Role turns. Optional action supplies this passage's attitude, vocal delivery, attention, interaction and any motivated cuts admitted by the Kit. In Speaker, performance selects the recurring approach to voice and visible expression; gesture selects body language, while action directs the particular thought and response. Do not retype the complete spoken text into action or treat each Role turn as a required new generated clip. For B-roll, story carries the silent visual events rather than spoken dialogue.

These files are reusable packaged authoring material. When one production needs a different prompt structure, author a project-local Text Template and import that Source explicitly rather than modifying the installed package. A Kit is not a Core restriction or a hidden media-generation wrapper. Reference order, duration, audio generation and output aspect ratio remain explicit on the model Surface. Setting a prompt option cannot create a media reference or execute a postprocess.

Speaker: edited UGC from one useful view

For ordinary direct-to-camera social video, explicitly select edit-rhythm: pause-trim-jump-cuts as the starting rhythm. Read the Hypit Skill's Video direction page for the directing judgment, and the Speaker template for the exact wording of its Recipe choices. Choose performance and gesture for the character's intended presence.

Reuse the same person-and-scene image and voice for ordinary generated clips belonging to one UGC performance. Each clip can begin from that shared reference and meet the others at a natural cut. There is no required previous-tail-frame chain. Independent generation follows the intended edited form.

For example, a lively ranking host can use:

speaker.host {
  composition-stability: strict-locked;
  camera-motion: none;
  edit-rhythm: pause-trim-jump-cuts;
  performance: high-energy-ugc;
  gesture: expressive;
}

edit-rhythm: pause-trim-jump-cuts asks the model for an edited pause-trim rhythm at phrase boundaries. It is compatible with a fixed camera and active performance. The template uses continuous-take when edit-rhythm is omitted; select that value when the passage calls for a continuous shot. Actual speed changes, trimming or audio extraction are explicit media operations; selecting this Recipe does not perform them on the returned video.

Podcast: two views and living listeners

@image1 is Host A's view, @image2 is Host B's view; @audio1 and @audio2 correspond to those hosts. If Script uses names such as GIRL and GUY, state their correspondence to A/B in action. One Segment can contain the entire short exchange. Choose speaker or reaction cuts for the conversation rather than splitting it into a generation per line.

Derive a complementary host view from the first useful scene image. Product variations normally derive from each host's own view plus the product reference. Action can state the meaningful handoff and resulting possession. Silent listeners can adjust posture, glance down and look back up; they must not speak the partner's lines. A split-screen opening has a different layout from this two-view template and can use its own explicit prompt and combined reference image.

Street interview: three supplied setups

The image order is interviewer A, guest B, shared two-person setup; the voice order is A, then B. The interviewer always holds the microphone, moving it between speaking positions. The guest does not take ownership merely because the microphone is extended toward them.

Action chooses cuts among the supplied setups. Guest answers can favor the guest close view, brief neutral questions the shared view, and a meaningful interviewer reaction their close view. Small opening and closing actions can establish an encounter: the guest looks up from another activity as the interviewer approaches, and begins to leave after the final answer. These are examples of motivated direction, not mandatory actions on every request.

Keep gesture and scene direction readable

Use attitude and a few decisive actions. Prefer an explanatory hand movement or emphatic gesture over exact numerical finger arrangements; speech or downstream graphics can state the number. Avoid exaggerated reactions or constantly moving every person simply to prevent stillness.

For a multi-scene B-roll montage, story can name the references in scene order and give each a small action. Choose an edit language compatible with cuts. “Continuous within each scene” and “one continuous shot for the whole montage” ask for different results.

Every Seedance image/video Reference requires person-reference="true|false": true if the supplied material contains a person, false otherwise. Audio must omit it. The Seedance author package explains person-reference and its frame variants. The Kit supplies direction; the actual reference edges supply media and metadata. For movement-led work, a reference video can carry the motion while the text explains what to preserve and change.
