activationHint
Invoke this before any media generation when the user asks for 宣传片, 广告片, 短片, 短视频, 视频, 口播视频, 数字人视频, 分镜, 分镜图, 图片转视频, reference-image video, product promotional video, character talking-head video, or an attached/reference image to become a video. In AI chat, all video-generation requests must enter this skill first. Do not call cosyvoice-ssml, tts-director, image.generate, voice.speech, or video.generate first; load this skill and follow its staged workflow.
Video Director
Use this skill before calling Operate(resource="video", operation="generate", input={ ... }) for video work.
For AI chat, this skill is the single entrypoint for video generation. If the user says "做一个口播视频", "生成一个视频", "产品宣传片", "广告片", "数字人视频", or any similar video request, invoke video-director first. Do not start from cosyvoice-ssml; that skill is an internal digital-human TTS substep and must not drive the video workflow.
If this skill was loaded because the user attached an image and asked for a promotional film / 宣传片 / 视频, treat the attached image as a product or visual reference for the video workflow. Do not generate a replacement product image as an "analysis" step.
Default Workflow
Treat the workflow as a gated state machine. Do not skip or reorder states:
plan_draft: Clarify the intended video mode from the user's goal and assets, then draft a concise but detailed video script and shot table.
storyboard_preview: Immediately after the shot table exists, generate storyboard contact-sheet preview image(s) with Operate(resource="image", operation="generate", input={ ... }). The storyboard image is a preview of the planned shots, not a standalone product poster, replacement product render, cover image, or final video keyframe.
user_review: Show the script, storyboard preview image(s), and explicit video specs together. Ask the user to confirm or revise the whole plan.
production_prep: After confirmation, decide whether this should be a <=15s single upstream clip, a long video_sequence request, or a manual editor/project assembly. Only use a video project pack if the user explicitly asks for a project/package/editor workflow, or the task is already bound to an existing pack.
tts_if_needed: If the confirmed task is a character talking-head / 口播 video, complete the TTS-first workflow below.
video_generate: Only after confirmation and any required TTS audio is complete, call Operate(resource="video", operation="generate", input={ ... }).
If the user has not yet confirmed the script, do not generate the video.
If the user has not yet seen and approved the storyboard preview image(s), do not generate the video.
If the shot table exists but no storyboard contact-sheet image has been generated yet, the next tool call must be image.generate for the storyboard preview, not video.generate, voice.speech, , or .
tts-director
cosyvoice-ssml
The storyboard contact-sheet preview is mandatory after the first shot script is written. It is not the same as final video keyframes; it is a quick visual proof of the planned shot sequence so the user can approve direction, composition, product placement, and continuity before video generation.
For product promotional videos from an attached/reference image:
The first image.generate call, if any, must be for a storyboard contact sheet after the script and shot table exist.
The storyboard prompt must explicitly say it is a multi-panel storyboard preview for the video, and it must preserve the attached/reference product's visible shape, material, color, and distinctive details.
Do not call image.generate just to "analyze", "extract", "enhance", or recreate the product reference.
Do not call video.generate until the user confirms the storyboard direction.
Asset-Library Character Talking-Head Rule
When the user wants a talking-head / 口播 / presenter / livestream welcome video using a character from the asset library, the character image is only the visual identity reference. It is not the speech track.
Keep these three inputs separate:
voiceId: the reusable cloned voice identity stored on the character asset. This is the primary voice field for future TTS calls.
voice sample / reference audio: fallback source material for cloning when no ready voiceId exists. Do not keep analyzing or presenting it once a ready voiceId has been found.
generated TTS audio asset: the completed spoken script. This is the only audio that should drive a character talking-head video.
Use this exact order:
Script and storyboard first
Confirm the final spoken script.
Confirm the storyboard / shot table.
The Sound column must contain the actual spoken lines, not vague labels like “角色讲解”.
Resolve the character voice
Read the selected character asset before generating media.
If the asset has a ready voiceId / voice_id, treat that as the resolved voice and stop inspecting voice samples. Report the resolved voiceId, not the reference-audio filename.
If the asset has a voice sample but no ready voiceId, call Operate(resource="voice", operation="clone", input={ ... }) first, wait for completion, and use the returned voiceId.
If there is no ready voiceId and no usable voice sample, stop and ask the user to provide or choose a voice. Do not fall back to a generic voice silently.
Generate the complete voice track with TTS
Call Operate(resource="voice", operation="speech", input={ ... }) with the full approved spoken script and the resolved voiceId.
Prefer one complete audio asset for the whole talking-head segment unless the user explicitly wants separate clips.
For expressive narration, long scripts, poetry, ads, or any multi-emotion performance inside this confirmed digital-human / VideoRetalk flow, activate tts-director first with Operate(resource="skills", operation="invoke", input={ "name": "tts-director" }), then use its guidance to split the approved script into semantic beats and assign model-appropriate delivery controls.
If the selected TTS model is CosyVoice, tts-director may activate cosyvoice-ssml only here, after the video-director workflow has confirmed this is a digital-human / VideoRetalk / asset-library talking-head video and the script plus role voice are resolved.
Add restrained delivery controls when they improve the approved performance: use speed for pace, pitch for tone, emotion for mood, expressive punctuation such as ～, ？, ！, ……, and MiniMax text markers such as <#0.6#>, (laughs), (sighs), or (breath) inside input only where the spoken rhythm needs them.
Do not write control instructions into the spoken text. For example, pass "emotion":"happy" and speed:1.08 instead of making the character say “用开心快速的语气”.
If the approved voice track needs multiple emotional beats, submit one voice.speech call with ordered segments; the media runtime will generate each segment and merge the final audio. Do not make repeated voice.speech calls and then manually merge.
Wait until the TTS result contains a usable audio asset path, URL, or asset id.
Do not start video generation while the TTS job is only queued or running.
Generate video with visual reference plus generated audio
Use the selected character image as the visual reference.
Use the newly generated complete TTS audio asset as drivingAudio.
Identify it in the prompt preface as generated speech audio, for example Audio 1: generated Jamba TTS speech for lip-sync / speaking rhythm.
Then call Operate(resource="video", operation="generate", input={ ... }), normally in reference-guided mode.
This is mandatory because the video model needs a finished audio waveform aligned with the approved script. A character voiceId is not audio. A voice sample is not the approved spoken line. The spoken text inside the video prompt is not a substitute for TTS.
Forbidden shortcuts:
Do not call video generation for character口播 with only the character image and a script.
Do not pass voiceId, voice sample audio, or “音色素材” as drivingAudio.
Do not rely on generateAudio to create the character voice for talking-head work.
Do not describe the intended speech only in the video prompt and expect the video model to synthesize it.
Do not split the TTS per storyboard row unless the user asks for separately editable audio clips or the video will be assembled from multiple independent speaking clips.
write the user brief and approved script back into the video project folder
keep later keyframes, clips, and outputs in the same pack whenever possible
Otherwise keep the planning in chat, call video generate directly, and let the output live in the generated media library.
Hard Rules
Video generation is locked to the official video route configured by the app.
Do not choose arbitrary video endpoints or third-party video models.
Use only these official model mappings:
text-to-video -> wan2.7-t2v-video
reference-guided -> wan2.7-r2v-video
first-last-frame -> wan2.7-i2v-video
Treat first/last-frame transitions as a subtype of image-to-video work.
A single upstream video generation segment must not exceed 15 seconds.
For a final video longer than 15 seconds, submit one video.generate request with either the final durationSeconds or explicit videoSegments; the media queue will generate <=15s segments and concatenate one final video asset.
Do not call video.generate repeatedly just to bypass the upstream 15 second segment limit.
Do not skip the script review step just because the request sounds obvious.
Unless the user explicitly asks for a longer continuous shot, a single shot should usually be 1-3 seconds.
Without explicit user approval, any single shot must not exceed 5 seconds.
Mode Selection
Use text-to-video when the user only provides text and wants a fresh video shot.
Use reference-guided when the user provides one or more reference images and wants the video to absorb subject elements, style cues, props, scene motifs, or composition hints from those images.
Use first-last-frame only when two images have explicit start/end semantics, such as “from A to B”, “首帧/尾帧”, “开头/结尾”, or “起始状态/结束状态”.
If the user gives two images but they are only style references, do not use first-last-frame; stay with reference-guided semantics instead.
Production Strategy
单视频模式:
Use one generated video clip.
Default when the request is simple, the action is short, and the full idea fits inside one coherent clip.
A single generated clip must not exceed 15 seconds.
长视频队列模式:
Use this for one final AI-generated video longer than 15 seconds.
Submit one video.generate request with durationSeconds > 15; the runtime will create a video_sequence queue job, split the generation into <=15s segments, wait for each segment, concatenate the segments, and return one final video asset.
Use explicit videoSegments when the storyboard needs scene-by-scene, beat-by-beat, reference-image, first/last-frame, or driving-audio control.
Each videoSegments[] item must be <=15 seconds and should correspond to a coherent group of approved storyboard rows.
Keep waitForCompletion: true unless the user explicitly asks to run the long generation in the background.
手动多视频工程模式:
Use this only when the user explicitly asks for separate clips, a project/editor workflow, imported clip assembly, manual post-production, or separately editable outputs.
In normal chat/agent video generation, do not manually generate one clip at a time and concatenate with ffmpeg; use 长视频队列模式 instead.
When manual assembly is explicitly needed, generate each clip deliberately, then concatenate them in storyboard order after all clips succeed.
If the request has multiple shots, clear continuity requirements, or a risk of visual drift, ask one more question after showing the contact-sheet preview:
whether separate storyboard keyframes should also be generated before video production.
If separate storyboard keyframes are generated, later video generation should preferentially use image-based modes, and for transition-heavy segments should prefer first-last-frame.
Storyboard-First Rule
Every video task needs a storyboard contact-sheet preview after the script table and before user confirmation.
Use generated individual keyframes in addition to the contact sheet when the request is complex enough that video quality depends on stable keyframes.
Use storyboard-first when one or more of these is true:
There are many shots or visual beats.
Character identity must remain highly stable.
Environment continuity matters.
The user wants a sequence that later becomes one assembled video.
The user explicitly asks for storyboard frames / keyframes / 分镜图.
When any of the above is true, do not silently continue to video generation after the contact sheet. Ask the user whether they also want separate image-generated storyboard keyframes before video generation.
When storyboard-first is used, follow this exact process:
First design a core environment reference image.
Generate that image first.
Then generate later keyframes one by one.
Each later keyframe must use the core environment reference image as a reference image.
If a character asset already exists in the asset library, the asset reference and the core environment reference should both be preserved across later keyframes.
Only after the keyframes are stable should video generation proceed.
Core Environment Reference Image
The first storyboard image should be a single overall environment master frame.
It must contain:
the full spatial layout,
the key environment elements,
the main subject placement,
the major props,
the lighting logic,
the camera worldview for the sequence.
This image acts as the environmental anchor for all later keyframes.
Do not start by generating an isolated close-up if the later sequence depends on environment continuity.
Storyboard Contact-Sheet Preview
After writing the script table, generate the required storyboard effect image(s) before asking for final video approval.
Use the shot count to choose the grid:
1-4 shots -> four-panel grid.
5-6 shots -> six-panel grid.
7-9 shots -> nine-panel grid.
More than 9 shots -> split into multiple contact sheets; each generated image contains at most 9 storyboard panels.
Rules:
One generated image may contain at most 9 storyboard panels.
A storyboard contact sheet is a single output image. Set count: 1 and put every panel description inside prompt.
Do not use imagePlanItems for storyboard contact sheets; imagePlanItems means separate image outputs unless the tool contract explicitly says otherwise.
Do not add extra invented shots to fill empty panels.
Keep the panel order left-to-right, top-to-bottom, matching the script table.
The preview should show composition, subject placement, camera scale, product/prop position, action beat, lighting, and style continuity.
Do not render planning labels, shot numbers, table headers, or internal notes inside the image unless the user explicitly asks for visible text.
The contact sheet is for visual approval only; it does not replace the approved Markdown script or storyboardShots payload used later for video generation.
Reference handling is mandatory:
Before any image.generate or video.generate call that depends on prior context, inspect the Current session resources block. If the needed file is not obvious there, call Operate(resource="session", operation="list", input={ "kind": "image", "limit": 20 }) or Operate(action="session.resources.list", payload={...}) and use the returned reference / path value exactly.
If the user attached or selected product images, character images, brand images, scene references, or previous generated images, pass them to image.generate as referenceImages.
If the reference comes from the asset library, read the asset first and pass its resolved image path(s) through referenceImages or subjectIds.
If several references exist, include prompt preface lines that define each role, such as Image 1: product shape and material reference, Image 2: character identity reference, Image 3: scene mood reference.
Do not describe reference images only in prose while leaving them out of the tool input.
Do not invent local paths, filenames, or user folders. Use only user-provided paths, asset-library paths, or session.resources.* results.
If there are more reference images than the tool supports, prioritize product/character identity first, then scene, then style.
{
"count": 1,
"generationMode": "reference-guided",
"aspectRatio": "16:9",
"prompt": "Image 1 is the product reference: preserve shape, material, logo position, and main color. Create one cinematic storyboard contact sheet with six panels arranged left-to-right, top-to-bottom. Each panel corresponds to one storyboard row: Panel 1 visual: ... Panel 2 visual: ... Panel 3 visual: ... Panel 4 visual: ... Panel 5 visual: ... Panel 6 visual: ... No visible labels, no captions, no table text.",
"referenceImages": ["/absolute/path/to/product.png"]
}
Use text-to-image only when there are no usable visual references. Use reference-guided whenever reference images, subject assets, product photos, or prior generated images exist.
Prompt Consistency Rules For Keyframe Images
When using image generation to build storyboard frames, consistency matters more than flourish.
You must:
Define one stable description block for the subject.
Define one stable description block for the environment.
Reuse those same description phrases across all keyframe prompts.
Only change the parts that truly differ from shot to shot.
The subject anchor should usually keep these elements stable:
name / identity,
gender or presentation if relevant,
age range if relevant,
hairstyle,
clothing,
key facial traits,
key props,
visual style.
The environment anchor should usually keep these elements stable:
place / room type,
layout,
background elements,
lighting mood,
color palette,
important objects,
time-of-day logic if relevant.
Do not rewrite the whole scene in a different wording for each frame.
Do not keep inventing new environment details frame by frame.
Do not vary the character description unless that change is intentional.
Keyframe Generation Order
If storyboard frames are generated:
Write one explicit subject anchor block.
Write one explicit environment anchor block.
Generate the core environment master frame first.
Generate each later keyframe individually.
Each later keyframe prompt should:
restate the same subject anchor,
restate the same environment anchor,
identify the core environment image as a reference,
describe only the shot-specific difference.
This is mandatory when the storyboard is later used for video generation.
If those storyboard frames have already been saved into a video project pack, later video generation should use those keyframes as the main visual references.
Do not keep reusing raw subject-library portraits or product stills as the primary visual input unless you truly need extra补充 angles or missing objects.
Script Format
The pre-generation script draft must be shown as a Markdown table. Use these columns:
Time
Picture
Sound
Shot
Requirements:
Before the table, explicitly state:
视频时长
视频比例
Time: use compact ranges such as 0-2s, 2-4s, 4-6s.
Picture: describe subject action, motion, camera movement, scene changes, and what must stay stable.
Sound: describe spoken line, ambient sound, music feel, silence, or rhythm cue.
Shot: describe shot scale / framing, such as close-up, medium shot, wide shot, push-in, pan, tilt.
Keep the table practical. It should be detailed enough to approve production, not a vague concept note.
Each row should usually represent a shot or one stable motion segment.
Shot duration should usually stay in the 1-3s range.
Without a clear user requirement, do not plan any row longer than 5s.
After the table, do not ask for final video approval yet. Generate the storyboard contact-sheet preview first, then show the table and storyboard together with one short confirmation prompt, for example:
请确认这版视频脚本，我确认后再正式生成。
If the user requests changes, revise the table, regenerate the storyboard contact-sheet preview when visual beats changed, and ask for confirmation again.
If duration or aspect ratio is not yet specified, propose a concrete default before generating the storyboard preview and include it in the confirmation block so the user can approve or change it.
If the script contains multiple shots, a named character, an important environment, or any continuity-sensitive sequence, also ask whether the user wants storyboard stills / keyframes first.
After the user confirms the video plan, the next assistant turn must either call video.generate or ask one blocking question required to build a valid payload. Do not reply that generation has started, is queued, or is complete until a video.generate tool result exists.
For chat/agent video creation, set waitForCompletion: true unless the user explicitly asks to run it in the background.
Prompt Discipline
Before writing the final video.generate prompt, reconstruct the current approved plan from the conversation context. Use the latest user-confirmed version, not an earlier draft.
The reconstruction must include:
the user's original goal and attached/reference files,
the selected slogan/copy,
approved duration, aspect ratio, style, and platform/use case,
the latest approved storyboard table,
the generated storyboard preview image or keyframe asset path, if one exists,
every user correction after the first script draft.
Do this silently as reasoning. Do not ask the user to repeat information that already exists in the conversation.
The final prompt must be written from that reconstructed plan. Do not write a fresh generic product-video prompt.
Before calling video.generate, run this self-check:
Does the payload include the latest approved storyboard as storyboardShots or storyboardMarkdown?
Does the prompt preserve the selected slogan/copy and the approved sound intent?
Does durationSeconds match the final storyboard time range?
Are the approved storyboard image/keyframe references included and labeled as strong references when available?
Does each beat contain concrete camera angle, framing, movement, and action details?
If any person appears, are posture, hand/arm movement, gaze, turn, prop interaction, and timing described?
If any self-check item fails, revise the prompt/payload before calling video.generate; do not proceed with an incomplete prompt.
If reference assets are attached, start the final generation prompt by identifying what each asset is for.
Use explicit labels such as:
Image 1: approved storyboard contact-sheet reference, strong reference for shot order, composition, framing, and visual continuity
Image 2: product reference, strong reference for shape, material, color, logo/details, and hardware
Image 3: Jamba portrait reference
Image 4: livestream background mood reference
Voice: Jamba voiceId for TTS = voice_xxx
Audio 1: generated Jamba TTS speech from the approved script
Do this before the motion/camera description so the model does not confuse multiple references.
If a storyboard contact sheet, storyboard still, or generated keyframe has been approved, treat that image as the primary visual reference for final video generation.
For final reference-guided video generation after storyboard approval, pass the approved storyboard image/keyframe path(s) in referenceImages whenever available. Do not keep using only the original product photo if an approved storyboard image exists.
The final prompt must explicitly say the storyboard image is a strong reference for composition, shot order, camera framing, lighting direction, product placement, and continuity. The model should animate from this plan rather than reinterpret the whole scene.
If a suitable finished generated speech audio exists and the chosen mode supports audio conditioning, treat it as a first-class reference asset instead of telling the user the platform cannot accept audio.
For asset-library character 口播 videos, do not treat a saved voiceId as Audio 1 directly. First synthesize the approved spoken script with TTS, then treat the generated audio asset as Audio 1.
If the request uses an asset from the asset library and that asset has a saved voiceId, use that voiceId as the default TTS voice for the spoken script unless the user explicitly asks to disable it or replace it. Do not surface the old reference-audio filename as the important result; the important result is the resolved voiceId.
For text-to-video, describe subject, camera, motion, environment, pacing, and visual style.
For reference-guided, describe the desired movement and cinematic behavior while preserving and combining the important elements from the provided reference images.
For first-last-frame, describe the transition between the first and last frame; do not rewrite the full scene unless the transition requires it.
Avoid bloated prompts that restate the whole image contents when the real task is only a motion or transition edit.
Focus on what should move, how the camera behaves, and what must stay stable.
After the user confirms a storyboard table, do not downgrade that approved script into a single generic sentence.
The final prompt must use professional cinematic language for every beat:
camera angle: eye-level, low angle, high angle, three-quarter angle, overhead, macro/product detail angle, over-the-shoulder, profile, frontal, rear tracking
framing and lens feel: wide shot, medium shot, medium close-up, close-up, extreme close-up, macro detail, shallow depth of field, compressed telephoto feel, natural wide-angle perspective
camera movement: slow dolly-in, lateral tracking shot, orbit move, pan, tilt, crane down, handheld micro-movement, locked-off shot, rack focus, reveal, whip-pan only when intentionally energetic
pacing and transition: hold, slow reveal, cut on motion, match cut, dissolve, speed ramp, final freeze frame
For any beat involving a person, describe physical action precisely. Include posture, hand/arm movement, walking direction, turning motion, gaze, facial expression, interaction with product/prop, timing relative to the camera move, and what must remain stable.
Do not use vague action words alone such as “show”, “display”, “model wears it”, or “fashion scene”. Replace them with concrete movement, for example: “model enters frame from camera right, lifts the bag strap onto the shoulder with the right hand, turns three-quarters toward camera, glances down at the gold zipper, then looks forward as the camera performs a slow dolly-in.”
The final tool call must carry the approved storyboard structure in payload.storyboardMarkdown or payload.storyboardShots, so the host can compile the execution prompt from the actual approved beats.
payload.storyboardShots should use one item per approved row with time, picture, sound, and shot.
If you only pass a vague summary prompt after script confirmation, that is a failure because it discards the approved shot structure.
Tool Usage
Always use Operate(resource="video", operation="generate", input={ ... }).
For asset-library character 口播 videos, resolve the voice before the video tool:
If the character has a ready voiceId, use it directly for TTS and do not inspect or summarize reference audio unless troubleshooting voice binding.
If the character has only a voice sample, call Operate(resource="voice", operation="clone", input={ ... }), wait for completion, and use the returned voiceId.
If no voice can be resolved, ask for a voice instead of generating a silent or generic-voice video.
After resolving the voice, call Operate(resource="voice", operation="speech", input={ ... }) before the video tool:
input: the full approved spoken script
voiceId: the selected character asset's stored voice id
speed: optional speech speed, 0.5-2.0; use subtle defaults such as 0.95 for steady narration or 1.05-1.12 for energetic口播
pitch: optional pitch, -12 to 12; keep 0 unless the character or user intent calls for a higher/lower tone
MiniMax text controls: use expressive punctuation such as ～, ？, ！, ……, ？！, ！！ for tone, <#0.6#> for intentional pauses, and (laughs), (sighs), (breath), (chuckle) for light expression when useful
Before building expressive or multi-beat TTS payloads, activate tts-director with Operate(resource="skills", operation="invoke", input={ "name": "tts-director" })
segments: use this for one long voice track with multiple emotional beats; submit once and let the media runtime merge the final audio
title: a clear audio asset title
projectId / boundManuscriptPath: include them when known
waitForCompletion: true when the runtime supports it, because video generation needs the completed audio asset
Use the resulting TTS asset path or URL as drivingAudio; never use the character voiceId or raw voice sample as drivingAudio.
Pass no reference images for text-to-video.
Pass 1 to 5 reference images for reference-guided.
After storyboard approval, put approved storyboard image/keyframe paths first in referenceImages, then product/character identity references, then scene/style references. Label the storyboard reference as strong.
Pass exactly two reference images in 首帧,尾帧 order for first-last-frame.
If a suitable finished audio asset exists, pass it as drivingAudio and describe it explicitly as Audio 1 in the prompt preface.
For reference-guided, if a suitable finished audio asset exists, also pass it as the mode's voice reference input.
When a subject-library character is used for 口播, default to that character's saved voiceId for TTS, then pass the generated TTS audio as Audio 1. A ready voiceId supersedes any stored reference-audio filename for planning and reporting.
If a video project pack already contains storyboard keyframes or image assets, prefer video-project-path or video-project-id together with those packaged assets as the main visual condition for reference-guided.
When the final prompt, script, or reference path list is long, keep them in payload instead of stuffing everything into one shell-like command string.
Keep the final generation prompt focused on execution details derived from the approved script.
Do not dump the whole planning discussion into the generation prompt.
When a storyboard has been approved, pass that exact approved table or row structure in payload. Recommended pattern:
{
"generationMode": "reference-guided",
"referenceImages": [
"/absolute/path/to/approved-storyboard-contact-sheet.png",
"/absolute/path/to/product-or-character-reference.png"
],
"referenceImageLabels": [
"approved storyboard contact-sheet reference, strong reference for shot order, composition, framing, lighting direction, product placement, and continuity",
"product or character identity reference, strong reference for shape, material, color, face/body identity, and distinctive details"
],
"prompt": "Image 1 is the approved storyboard contact-sheet and must be followed as a strong reference for composition, shot order, framing, lighting direction, product placement, and continuity. Image 2 is the product/character identity reference and must preserve the visible identity details. Use professional cinematic camera language for every beat: specify angle, framing, lens feel, camera movement, pacing, and transition. If a person appears, describe posture, hand movement, gaze, body turn, prop interaction, and timing relative to the camera.",
"storyboardShots": [
{
"time": "0-2s",
"picture": "Jamba 手持戴森 V8 吸尘器，身体随节奏左右摇摆，吸尘器作为道具举起。",
"sound": "使用 Jamba 已绑定 voiceId 生成的 TTS 口播，轻快节奏感。",
"shot": "中景，人物全身入镜。"
},
{
"time": "2-4s",
"picture": "Jamba 一边跳舞一边用吸尘器做挥舞动作，身体转动，动作夸张有趣。",
"sound": "节奏感音乐 + Jamba voiceId 生成的 TTS 声音。",
"shot": "中近景，跟随人物移动。"
}
]
}
For final videos longer than 15 seconds, use the queue's long-video capability in one tool call. If the approved storyboard is clear enough to split automatically, pass the final durationSeconds and the approved storyboardShots:
{
"generationMode": "reference-guided",
"durationSeconds": 45,
"referenceImages": [
"/absolute/path/to/approved-storyboard-contact-sheet.png",
"/absolute/path/to/product-or-character-reference.png"
],
"prompt": "Create one continuous 45-second final video from the approved storyboard. The runtime may split it into <=15 second generation segments, but the user-facing output should be one complete concatenated video. Preserve visual continuity across segment boundaries.",
"storyboardShots": [
{
"time": "0-5s",
"picture": "Opening product reveal with slow dolly-in.",
"sound": "Music intro.",
"shot": "Wide shot to medium close-up."
},
{
"time": "5-12s",
"picture": "Presenter enters and demonstrates the product.",
"sound": "Approved voiceover line.",
"shot": "Medium shot with slow lateral tracking."
}
],
"waitForCompletion": true
}
Use explicit videoSegments when segment boundaries, references, mode, audio, or prompt details must be controlled. Each segment must be <=15 seconds:
{
"generationMode": "reference-guided",
"durationSeconds": 45,
"videoSegments": [
{
"durationSeconds": 15,
"prompt": "Segment 1: opening reveal from storyboard rows 1-3. Keep the product centered and preserve the approved lighting.",
"referenceImages": ["/absolute/path/to/keyframe-1.png"]
},
