description	Generate AI videos from text prompts or reference materials. Supports HappyHorse, SeeDance, and PixVerse models. Triggers on: "生成视频", "做视频", "video generation", "text to video", "create video", "视频生成", "视频编辑", "video edit", "pixverse", "口型", "lipsync", "对口型".

When to Use

• User wants to generate an AI video from a text description
• User wants to animate a still image (first-frame)
• User has reference images to guide video generation
• User wants to edit an existing video (change style, background, etc.)
• User wants to lip-sync a video to audio or TTS (PixVerse only) — "对口型", "口型同步"
• User wants a marketing ad / promo mix video (PixVerse agent)
• User says "生成视频", "做视频", "video generation", "text to video", "视频编辑", "pixverse", "口型"

When NOT to Use

• User wants an explainer video with narration and AI visuals (use /explainer)
• User wants to transcribe audio/video to text (use /asr)
• User wants to generate an image (use /image-gen)

Purpose

Generate AI videos using the ListenHub CLI. Supports three model families:

• HappyHorse (default) — text-to-video, image-to-video, reference-image-to-video, video-edit
• SeeDance — text-to-video, frame mode (first + last frame), reference mode (images, videos, audio)
• PixVerse — nine atomic capabilities via the Agent API (text_to_video, image_to_video, transition, multi_transition, fusion, restyle, mimic, lip_sync, agent). The only family that supports lip sync. OpenAPI-only, URL/ID based, and uses its own pixverse CLI namespace.

Hard Constraints

• Always check CLI auth following shared/cli-authentication.md
• Follow shared/cli-patterns.md for CLI execution, errors, and interaction patterns
• Always read config following shared/config-pattern.md before any interaction
• Follow shared/output-mode.md for result presentation — download mode saves {slug}.mp4 to cwd with dedupe per shared/config-pattern.md § Artifact Naming
• Always use --no-wait --json for video creation — generation takes minutes
• Never use eval to execute CLI commands — always invoke listenhub video ... directly with proper quoting

Use the AskUserQuestion tool for every multiple-choice step — do NOT print options as plain text. Ask one question at a time. Wait for the user's answer before proceeding to the next step. After all parameters are collected, summarize the choices and ask the user to confirm. Do NOT call the video generation command until the user has explicitly confirmed.

Resolution / quality	720p, 1080p	480p, 720p, 1080p	360p, 540p, 720p, 1080p
Duration range	3–15s	4–15s	1–60s (agent: 20/30/60)
Aspect ratios	16:9, 9:16, 1:1, 4:3, 3:4, 4:5, 5:4	16:9, 9:16, 1:1, 4:3, 3:4, 21:9	9:16, 16:9, 1:1, 4:3, 3:4

Lip sync is PixVerse-only — HappyHorse and SeeDance do not support it. Mimic, restyle, fusion, transition, and the marketing agent are also PixVerse-exclusive.

Step -1: CLI Auth Check + Video Command Gate

Follow shared/cli-authentication.md § Auth Check. If CLI is not installed or not logged in, auto-install and auto-login — never ask the user to run commands manually.

After standard auth check, verify the video subcommand is available:

if ! listenhub video --help &>/dev/null; then
  npm install -g @marswave/listenhub-cli@latest
  if ! listenhub video --help &>/dev/null; then
    echo "VIDEO_COMMAND_UNAVAILABLE"
  fi
fi

If VIDEO_COMMAND_UNAVAILABLE: stop and tell the user:

video-gen 需要 listenhub-cli 的最新版本，当前已安装版本不包含 video 命令，请等待新版发布。

Auth Mode Detection

The CLI supports two auth modes. Detect which one is active:

# Check if OpenAPI key is configured
OPENAPI_STATUS=$(listenhub openapi config show --json 2>/dev/null)
HAS_OPENAPI=$(echo "$OPENAPI_STATUS" | jq -r '.source // empty')

# Check if internal auth is active
AUTH=$(listenhub auth status --json 2>/dev/null)
HAS_INTERNAL=$(echo "$AUTH" | jq -r '.authenticated // false')

Priority: If both are configured, prefer internal auth (richer features). Set a session variable:

if [ "$HAS_INTERNAL" = "true" ]; then
  CMD_PREFIX="listenhub video"
elif [ -n "$HAS_OPENAPI" ]; then
  CMD_PREFIX="listenhub openapi video"
else
  # Neither configured — trigger internal auth login
  listenhub auth login
  CMD_PREFIX="listenhub video"
fi

All subsequent commands use $CMD_PREFIX instead of hardcoded listenhub video. The flags and JSON output format are identical between the two modes.

OpenAPI-specific notes:

• OpenAPI mode requires API Key (lh_sk_...), configured via listenhub openapi config set-key or env LISTENHUB_API_KEY
• OpenAPI mode does not support --audio-setting flag (video-edit audio control not yet exposed)
• Standard listenhub openapi video create accepts local image/video/audio paths or URLs. Local files are uploaded by the CLI before task creation; local images also get width/height/size metadata automatically.
• Remote Seedance image URLs still need explicit --*-meta values because the CLI does not download remote assets to infer dimensions.
• PixVerse is OpenAPI-only — it lives under listenhub openapi video pixverse and has no internal-auth equivalent. If the user wants PixVerse (口型/mimic/restyle/fusion/transition/agent) but only internal auth is configured, prompt them to configure an OpenAPI key first.
• PixVerse media inputs remain URL/ID based. Do not pass local paths to listenhub openapi video pixverse generate; ask the user for public URLs or prior PixVerse task/video IDs.

Step 0: Config Setup

Follow shared/config-pattern.md Step 0 (Zero-Question Boot).

If file doesn't exist — silently create with defaults and proceed:

mkdir -p ".listenhub/video-gen"
echo '{"outputMode":"inline"}' > ".listenhub/video-gen/config.json"
CONFIG_PATH=".listenhub/video-gen/config.json"
CONFIG=$(cat "$CONFIG_PATH")

Session defaults (not persisted unless user reconfigures):

• model: happyhorse
• resolution: 1080p
• ratio: 16:9
• duration: 5

Do NOT ask any setup questions. Proceed directly to the Interaction Flow.

If file exists — read config silently and proceed:

CONFIG_PATH=".listenhub/video-gen/config.json"
[ ! -f "$CONFIG_PATH" ] && CONFIG_PATH="$HOME/.listenhub/video-gen/config.json"
CONFIG=$(cat "$CONFIG_PATH")

Setup Flow (user-initiated reconfigure only)

Only run when the user explicitly asks to reconfigure. Display current settings:

当前配置 (video-gen)：
  输出方式: {outputMode}

Then ask:

1. outputMode: Follow shared/output-mode.md § Setup Flow Question.

Save immediately:

NEW_CONFIG=$(echo "$CONFIG" | jq --arg m "$OUTPUT_MODE" '. + {"outputMode": $m}')
echo "$NEW_CONFIG" > "$CONFIG_PATH"
CONFIG=$(cat "$CONFIG_PATH")

Interaction Flow

Step 1: Collect Prompt

Ask the user for a video description. If they haven't provided one:

描述你想要生成的视频内容。

Free text input. Use as-is — do not modify the prompt unless the user asks for help.

Step 2: Mode Routing

Question: "你有参考素材想提供吗？"
Options:
  - "没有，纯文字生成" — Text-to-video mode, skip to Step 4
  - "有图片，想做首帧动画" — Image-to-video (first-frame) → Step 3a
  - "有参考图片（风格/角色参考）" — Reference-image mode → Step 3b
  - "有视频，想编辑/修改" — Video-edit mode → Step 3c
  - "有视频，想做口型同步" — Lip-sync mode (PixVerse only) → Step 3d

If the user mentions PixVerse-exclusive capabilities (口型/lip sync, 模仿/mimic, restyle/风格化、融合/fusion、过渡/transition、广告/promo agent), route to PixVerse and pick the matching --capability — see Step 4 (PixVerse) and references/pixverse-api.md.

Step 3a: Image-to-Video (First-Frame)

1. first-frame (required): Ask for the image path or URL.

   • Supported formats: jpg, jpeg, png, webp
   • Local image files max 10MB
   • Image: width & height ≥ 300px, ratio between 1:2.5 and 2.5:1
   • Local images: CLI auto-populates Seedance metadata. Remote Seedance image URLs require --first-frame-meta WIDTHxHEIGHT[:SIZE].

2. last-frame (optional, SeeDance only): If model is SeeDance, ask if there is a last-frame image.

Question: "有尾帧图片吗？（仅 SeeDance 支持）"
Options:
  - "没有，只用首帧" — Skip last-frame
  - "有" — Collect last-frame path/URL

After collecting, proceed to Step 4.

Note: HappyHorse i2v mode has no ratio parameter — ratio is determined by the input image. SeeDance still accepts --ratio.

Step 3b: Reference-Image Mode

Collect reference images (1–9 images required).

Ask for image paths/URLs:

• Supported formats: jpg, jpeg, png, webp
• Local image files max 10MB
• HappyHorse: short edge ≥ 400px recommended
• Local images: CLI auto-populates Seedance metadata. Remote Seedance image URLs require matching --reference-image-meta WIDTHxHEIGHT[:SIZE] values.

HappyHorse prompt syntax: When multiple reference images are provided, the user can use [Image 1], [Image 2] etc. in the prompt to refer to specific images. Inform the user of this capability.

SeeDance additional references (only if model is SeeDance):

• reference-video (optional, max 3): mp4, mov, max 50MB
• reference-audio (optional, max 3): mp3, wav, max 20MB (must pair with image or video)
• reference-video metadata is required: provide --reference-video-meta WIDTHxHEIGHT[:DURATION[:FPS[:SIZE]]] for each video.

After collecting, proceed to Step 4.

Step 3c: Video-Edit Mode (HappyHorse Only)

If model is SeeDance, inform the user: "视频编辑仅 HappyHorse 模型支持，已自动切换。" and set model to happyhorse.

1. video (required): Ask for the video path or URL.

   • Supported formats: mp4, mov (H.264 recommended)
   • Duration: 3–60s (output capped at 15s)
   • Max 100MB, ≥ 360px short edge, ≤ 4096px long edge
   • URL only (no base64)

2. reference-image (optional, 0–5): Ask if there are reference images for the edit.

3. audio-setting:

Question: "音频如何处理？"
Options:
  - "自动（模型决定）" — audio_setting: auto
  - "保留原声" — audio_setting: origin

After collecting, proceed to Step 4.

Note: Video-edit has no ratio or duration parameters — output matches input video.

Step 3d: Lip-Sync Mode (PixVerse Only)

Lip sync is only available on PixVerse (--capability lip_sync). If the user is on HappyHorse/SeeDance, inform them: "口型同步仅 PixVerse 模型支持，已自动切换。" and use the PixVerse command template in Step 4.

1. source video (required): the video whose lips will be driven. Collect EITHER:

   • --source-video-id <id> — a PixVerse video id, OR
   • --source-task-id <id> — a prior succeeded PixVerse task to reuse.

   (OpenAPI-only; the source must already exist on PixVerse.)

2. audio source — ask the user which drive method:

Question: "口型用什么驱动？"
Options:
  - "用一段音频文件" — Collect 1 audio URL → --audio <url>
  - "用文字转语音 (TTS)" — Collect speaker + content → --pixverse-json '{"tts":{...}}'

• Audio file: collect one public audio URL → --audio <url> (max 1)，音频时长须落在 5–60s。
• TTS: collect a speaker id and the text to speak，走嵌套 JSON（不要用 --lip-sync-* flag，详见 references/pixverse-api.md § lip_sync）：
  • --pixverse-json '{"tts":{"speakerId":"<id>","content":"<text>"}}'

Do NOT mix audio and TTS — pick one（同时给两者会被契约拒绝）。

After collecting, proceed to Step 4 (use the PixVerse lip_sync template).

Step 4: Optional Parameter Adjustment

Read session defaults and present. Adjust display based on mode:

For text-to-video and reference-image modes:

Question: "要调整生成参数吗？当前默认配置：\n  模型: happyhorse\n  分辨率: 1080p\n  比例: 16:9\n  时长: 5 秒"
Options:
  - "用默认，直接生成" — Proceed to Step 5
  - "我要调整参数" — Ask each parameter below

For image-to-video (first-frame) mode:

Question: "要调整生成参数吗？当前默认配置：\n  模型: happyhorse\n  分辨率: 1080p\n  时长: 5 秒"
Options:
  - "用默认，直接生成" — Proceed to Step 5
  - "我要调整参数" — Ask each parameter below

For video-edit mode: Skip Step 4 entirely — no adjustable generation params (only resolution).

If adjusting, ask each parameter one at a time:

Model:

Question: "模型？"
Options:
  - "happyhorse（推荐）" — Higher quality, video-edit support
  - "doubao-seedance-2-pro" — SeeDance pro, supports last-frame & audio ref
  - "doubao-seedance-2-fast" — SeeDance fast
  - "pixverse" — PixVerse: 口型同步/模仿/风格化/融合/过渡/广告 agent (OpenAPI only)

If the user picks pixverse, switch to the PixVerse command templates below — PixVerse uses its own … video pixverse generate namespace, an explicit --capability, and --quality/--aspect-ratio instead of --resolution/--ratio. See "PixVerse Command Templates" and references/pixverse-api.md.

Resolution:

Question: "分辨率？"
Options:
  - "1080p（推荐）" — High quality (default for HappyHorse)
  - "720p" — Standard quality
  - "480p" — Low quality (SeeDance only)

Constraint: if user selects 480p and model is happyhorse, inform "HappyHorse 不支持 480p，已切换为 720p。" Constraint: if user selects 1080p and model is doubao-seedance-2-fast, silently upgrade to doubao-seedance-2-pro and inform "1080p 需要使用 pro 模型，已自动切换。"

Aspect ratio (not shown for i2v or video-edit):

Question: "画面比例？"
Options:
  - "16:9" — Landscape, widescreen
  - "9:16" — Portrait, phone screen
  - "1:1" — Square
  - "Other" — 4:3, 3:4, 4:5, 5:4 (4:5/5:4 HappyHorse only)

Duration:

Question: "时长？"
Options:
  - "5 秒（推荐）" — Standard
  - "8 秒" — Medium
  - "10 秒" — Long
  - "Other" — Custom (HappyHorse: 3–15, SeeDance: 4–15)

Seed (optional): Only ask if the user mentions wanting to reproduce a result. Otherwise skip.

Step 5: Cost Estimate + Execution Confirmation

Build and run the estimate command (no eval — direct invocation):

ESTIMATE=$($CMD_PREFIX estimate \
  --model "happyhorse" \
  --resolution "1080p" \
  --duration 5 \
  --ratio "16:9" \
  --json 2>/tmp/lh-err)
EXIT_CODE=$?

For video-edit mode — add --has-video-input and --input-video-duration:

• If user provided a URL: ask duration
• Local files: detect with ffprobe as best-effort:

  INPUT_DUR=$(ffprobe -v error -show_entries format=duration -of csv=p=0 "/path/to/ref.mp4" 2>/dev/null | cut -d. -f1)
  

  If ffprobe is unavailable or fails, skip estimate — show "预估不可用" in the summary.

ESTIMATE=$($CMD_PREFIX estimate \
  --model "happyhorse" \
  --resolution "1080p" \
  --has-video-input \
  --input-video-duration "$INPUT_DUR" \
  --json 2>/tmp/lh-err)
EXIT_CODE=$?

Parse estimate result:

if [ $EXIT_CODE -eq 0 ]; then
  TOKENS=$(echo "$ESTIMATE" | jq -r '.tokens // empty')
  CREDITS=$(echo "$ESTIMATE" | jq -r '.credits // empty')
else
  TOKENS=""
  CREDITS=""
fi
rm -f /tmp/lh-err

Present confirmation summary:

Ready to generate video:

  Prompt: {prompt text}
  模式: {纯文字 / 首帧动画 / 参考图 / 视频编辑}
  模型: {model}
  分辨率: {resolution}
  比例: {ratio or "跟随输入"}
  时长: {duration} 秒 {or "跟随输入"}
  素材: {无 / first-frame: path / references: N 个 / video: path}
  预估费用: {tokens} tokens / {credits} credits    ← or "预估不可用" if estimate failed

  确认生成？

Wait for explicit confirmation before executing.

Execution & Polling

Submit (foreground)

Invoke $CMD_PREFIX create directly — never build a command string with eval. Substitute the actual collected values into the command. $CMD_PREFIX is either listenhub video (internal auth) or listenhub openapi video (API Key auth), determined in Step -1.

  --no-wait --json 2>/tmp/lh-err)
EXIT_CODE=$?

PixVerse Command Templates

PixVerse uses its own namespace and an explicit --capability. It is OpenAPI-only, so $CMD_PREFIX must be listenhub openapi video — invoke … pixverse generate (not … create). PixVerse media inputs are public URLs or prior PixVerse task/video IDs; do not pass local file paths here. Quality uses --quality (360p/540p/720p/1080p) and ratio uses --aspect-ratio (9:16/16:9/1:1/4:3/3:4); there is no --resolution/--ratio here.

text_to_video:

RESULT=$(listenhub openapi video pixverse generate \
  --capability text_to_video \
  --model pixverse \
  --prompt "赛博朋克城市夜景" \
  --quality 720p \
  --aspect-ratio 16:9 \
  --duration 5 \
  --no-wait --json 2>/tmp/lh-err)
EXIT_CODE=$?

image_to_video:

RESULT=$(listenhub openapi video pixverse generate \
  --capability image_to_video \
  --model pixverse \
  --prompt "让画面里的人物自然走动" \
  --image "https://example.com/scene.png" \
  --quality 720p \
  --aspect-ratio 16:9 \
  --duration 5 \
  --no-wait --json 2>/tmp/lh-err)
EXIT_CODE=$?

lip_sync (audio file): source video + 1 audio URL.

RESULT=$(listenhub openapi video pixverse generate \
  --capability lip_sync \
  --source-video-id "abc123" \
  --audio "https://example.com/voice.mp3" \
  --quality 720p \
  --no-wait --json 2>/tmp/lh-err)
EXIT_CODE=$?

lip_sync (TTS): source video + nested tts（do NOT also pass --audio）。TTS 必须走 --pixverse-json 的嵌套 tts，不要用 --lip-sync-tts/--lip-sync-speaker-id/--lip-sync-content（那三个 flag 映射到 lipSyncTts*，校验器/provider 不认，会被拒绝——上游 listenhub-cli #250 的 flag→字段错配）。

RESULT=$(listenhub openapi video pixverse generate \
  --capability lip_sync \
  --source-task-id "task_xyz" \
  --pixverse-json '{"tts":{"speakerId":"speaker_01","content":"大家好，欢迎来到本期节目"}}' \
  --quality 720p \
  --no-wait --json 2>/tmp/lh-err)
EXIT_CODE=$?

mimic: 1 image + 1 video, quality locked to 720p.

RESULT=$(listenhub openapi video pixverse generate \
  --capability mimic \
  --image "https://example.com/subject.png" \
  --video "https://example.com/motion.mp4" \
  --quality 720p \
  --no-wait --json 2>/tmp/lh-err)
EXIT_CODE=$?

agent (ad_master / promo_mix): quality 720p/1080p only, duration 20/30/60 only; promo_mix needs ≥4 images.

RESULT=$(listenhub openapi video pixverse generate \
  --capability agent \
  --agent-type promo_mix \
  --prompt "为这款耳机做一支 30 秒带货短片" \
  --image "https://example.com/p1.png" \
  --image "https://example.com/p2.png" \
  --image "https://example.com/p3.png" \
  --image "https://example.com/p4.png" \
  --quality 1080p \
  --duration 30 \
  --no-wait --json 2>/tmp/lh-err)
EXIT_CODE=$?

fusion: 参考图走嵌套 imageReferences（不要用 top-level --image，否则契约 any.invalid 拒绝）；prompt 须为每个 refName 写 @refName。type 取 subject/background，refName 须匹配 /^[A-Za-z][A-Za-z0-9_]{0,31}$/。

RESULT=$(listenhub openapi video pixverse generate \
  --capability fusion \
  --prompt "让 @cat 在 @city 的街道上奔跑" \
  --pixverse-json '{"imageReferences":[{"type":"subject","imageUrl":"https://example.com/cat.png","refName":"cat"},{"type":"background","imageUrl":"https://example.com/city.png","refName":"city"}]}' \
  --quality 720p \
  --no-wait --json 2>/tmp/lh-err)
EXIT_CODE=$?

multi_transition: 关键帧走嵌套 multiTransition（2–7 个 {imageUrl,duration,prompt}；不要用 top-level --image），默认 quality 360p。

RESULT=$(listenhub openapi video pixverse generate \
  --capability multi_transition \
  --pixverse-json '{"multiTransition":[{"imageUrl":"https://example.com/k1.png","duration":3,"prompt":"清晨的城市"},{"imageUrl":"https://example.com/k2.png","duration":3,"prompt":"正午的广场"},{"imageUrl":"https://example.com/k3.png","duration":3,"prompt":"夜晚的霓虹"}]}' \
  --quality 360p \
  --no-wait --json 2>/tmp/lh-err)
EXIT_CODE=$?

PixVerse capability constraints (enforce before submitting):

• mimic — quality locked 720p (other values rejected); needs 1 image + 1 video，运动源视频时长 5–30s。
• agent — quality 720p/1080p only, duration 20/30/60 only; promo_mix requires ≥4 images.
• multi_transition — 关键帧走 --pixverse-json 的 multiTransition[]（2–7 个），top-level --image 必须为空；default quality 360p。
• fusion — 参考图走 --pixverse-json 的 imageReferences[]（1–8 个），top-level --image 必须为空；prompt 须为每个 refName 写 @refName。
• lip_sync — source video (--source-video-id/--source-task-id) + EITHER 1 --audio（5–60s）OR nested tts（--pixverse-json '{"tts":{...}}'，勿用 --lip-sync-* flag）；二者不能同时给。
• restyle — --source-video-id (or --source-task-id) + --restyle-id.

PixVerse estimate (mirror the generate capability + quality/duration):

ESTIMATE=$(listenhub openapi video pixverse estimate \
  --capability text_to_video \
  --model pixverse \
  --quality 720p \
  --duration 5 \
  --json 2>/tmp/lh-err)
EXIT_CODE=$?

For agent add --agent-type ad_master (or promo_mix).

Flags only when needed:

• --no-generate-audio — only if user disabled audio (SeeDance only)
• --seed 12345 — only if user specified a seed
• --audio-setting origin — video-edit mode, keep original audio
• --input-video-duration N — required with --reference-video (2-15s)

VIDEO_URL=$(echo "$RESULT" | jq -r '.videoUrl')
DURATION=$(echo "$RESULT" | jq -r '.duration')
RESOLUTION=$(echo "$RESULT" | jq -r '.resolution')
RATIO=$(echo "$RESULT" | jq -r '.ratio')
SEED=$(echo "$RESULT" | jq -r '.seed')
CREDITS=$(echo "$RESULT" | jq -r '.creditCharged')

Read OUTPUT_MODE from config. Follow shared/output-mode.md for behavior.

inline or both: Display video URL and metadata.

Present:

视频已生成！

  URL: {videoUrl}
  时长: {duration}s
  分辨率: {resolution}
  比例: {ratio}
  Seed: {seed}
  消耗: {creditCharged} credits

download or both: Save to current working directory with a topic-based slug per shared/config-pattern.md § Artifact Naming:

SLUG="{topic-slug}"  # e.g. "赛博朋克城市夜景"
NAME="${SLUG}.mp4"
BASE="${NAME%.*}"; EXT="${NAME##*.}"; i=2
while [ -e "$NAME" ]; do NAME="${BASE}-${i}.${EXT}"; i=$((i+1)); done
curl -sS -o "$NAME" "$VIDEO_URL"

Present:

已保存到当前目录：
  {NAME}

On failure: Display error and suggest checking prompt or parameters.

On timeout: Tell the user to check later:

生成超时。你可以稍后用 listenhub video get {taskId} --json（或 listenhub openapi video get {taskId} --json）查询结果。

Querying Past Tasks

Users can ask to check a previous task or list recent tasks:

# Get a specific task
$CMD_PREFIX get "{taskId}" --json

# List recent tasks
$CMD_PREFIX list --json

Present results using the same format as the success output above.

Error Handling

Reuse shared/cli-patterns.md standard error codes:

Code	Meaning	Action
0	Success	Parse JSON output
1	General error	Display stderr to user
2	Auth error	Internal: re-login via listenhub auth login. OpenAPI: check API Key via listenhub openapi config show
3	Timeout	Suggest checking task status later
