Video Gen

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

Model Comparison

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.

  --reference-image "/path/to/ref.png" \
  --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)
