Vidau Video Generator

Output format (task success)

When a video task succeeds, return:

• Video URL (verbatim, from [VIDAU_VIDEO_URL] … [/VIDAU_VIDEO_URL])
• Thumbnail URL (verbatim, from [VIDAU_THUMB_PATH] … [/VIDAU_THUMB_PATH])

Always present both URLs in a code block so they are preserved verbatim and less likely to be altered by downstream processing. Example:

Video URL: <paste exact URL from script output>
Thumbnail URL: <paste exact URL from script output>

Do not rewrite, truncate, or wrap the URLs in other markup; copy them exactly from the script output.

Prerequisites

Environment variable VIDAU_API_KEY must be set (injected by OpenClaw from skills.entries.vidau.apiKey or env). If the user has no API key, they must register at https://www.superaiglobal.com/ to get one. Do not trigger this skill if it is not configured.

Environment check

Before running any script, ensure Python 3 is available:

1. Run python3 --version or python --version. If either succeeds, use that command when invoking the scripts below.
2. If both fail, try to install Python for the current platform:
   • macOS: brew install python3 (requires Homebrew).
   • Linux (Debian/Ubuntu): sudo apt-get update && sudo apt-get install -y python3.
   • Windows: winget install Python.Python.3.12 if available; otherwise tell the user to download and run the installer from python.org.
3. If install fails (e.g. no permission or unsupported OS), reply with a short message that Python 3 is required and link to python.org/downloads, then stop. Do not run the Vidau scripts until Python is available.

The scripts use only the standard library; no pip packages are required.

Available scripts

• scripts/query_credit.py — Query current available credits; no args; outputs JSON with data.availableCredit, data.userId.
• scripts/query_models.py — Query model list and capability config; no args (optional --no-cache to force refresh); outputs JSON with data array. Each item has model, scaleList, durationList, resolutionList, generateAudio. Cached 10 minutes (env VIDAU_MODELS_CACHE or ~/.vidau_models_cache.json). Use before create_task to validate user parameters. After new models or capability changes, use --no-cache to force refresh so the agent does not validate against a stale list.
• scripts/upload_asset.py — Upload a local file (image or video) to Vidau; outputs JSON with data.url and data.assetId. Use data.url as --image-url / --last-image-url / --ref-image-urls in create_task when the user only has a local file. Caches by file content hash (default ~/.vidau_asset_cache.json, override with env VIDAU_ASSET_CACHE) so the same file is not re-uploaded.
• scripts/create_task.py — Create video task; required --prompt, optional --model, etc.; outputs JSON with data.taskUUID.
• scripts/wait_task.py — Poll until task succeeds or fails (or timeout); required --task-uuid; optional --interval (default 10s), --timeout (default 600s = 10 min). On success outputs same JSON as query_task and the same [VIDAU_VIDEO_URL] / [VIDAU_THUMB_PATH] blocks. Exit code 0 = succeeded, 1 = failed, 2 = timeout. Always use wait_task by default; when using wait_task you do not need to handle DELETE_SCHEDULED_TASK.
• scripts/query_task.py — Query task status and result once; required --task-uuid; outputs JSON with taskStatus, and on success also prints [VIDAU_VIDEO_URL] / [/VIDAU_VIDEO_URL] and [VIDAU_THUMB_PATH] / [/VIDAU_THUMB_PATH] blocks. Use query_task only when the platform requires scheduled polling. When the task reaches succeeded or , the script prints to stderr so the platform can remove the scheduled polling task.

Task polling (wait_task vs query_task): By default always use wait_task; use query_task only when the platform requires scheduled task polling. When using wait_task, there is no need to handle DELETE_SCHEDULED_TASK.

Workflow (generate video)

1. Optional: Call scripts/query_credit.py to check availableCredit before creating a task to avoid failures due to insufficient credits.
2. If the user only has a local image/video (no URL yet): Call scripts/upload_asset.py <path> to upload the file; read data.url from stdout and use it as --image-url, --last-image-url, or in --ref-image-urls when calling create_task.
3. Validate parameters against model capabilities: Call scripts/query_models.py to get the model list (cached 10 min). Find the entry in data where model equals the chosen --model. Validate user inputs (resolution, ratio, duration, generate_audio) against that entry:
   • resolution: must be in the model’s resolutionList. If not, do not create the task; tell the user the resolution is not supported and list the allowed values (e.g. resolutionList).
   • ratio (if user specified one): must be in the model’s scaleList. If not, do not create the task; tell the user the ratio is not supported and list the allowed values (e.g. scaleList).
   • duration (if user specified one): for the chosen resolution, allowed durations are in durationList[resolution] (e.g. durationList["1080p"] = [5, 10]). If the user’s duration is not in that list, do not create the task; tell the user the duration is not supported for this resolution and list the allowed durations (e.g. for 1080p: 5, 10 seconds).
   • generate_audio (if user requested true): the model entry’s generateAudio must be true. If it is false, do not create the task; tell the user this model does not support audio generation. If any check fails, reply with what does not meet requirements and the allowed values; do not change the user’s parameters automatically and do not call create_task. If the chosen model is not in the list, skip validation and proceed to create_task.
4. Call scripts/create_task.py with --prompt (required), --resolution (required), --model (default veo@3:normal), and optional args (see parameter table below).
5. Read data.taskUUID from the script’s stdout JSON.
6. Always use wait_task by default: run scripts/wait_task.py --task-uuid <taskUUID> to poll until done (default 10s interval, 10 min timeout). When using wait_task . use and, when the task reaches a terminal state, remove the scheduled task using the line on stderr.

Workflow (query credits)

When the user asks for balance, call scripts/query_credit.py (no args), read data.availableCredit from stdout JSON and reply; optionally include data.userId.

Parameters (create_task.py)

Defaults when unspecified: 720p / 8s / 16:9 (see references/parameters.md). Note: create_task currently requires passing --resolution explicitly; the agent must always include this parameter for consistent behavior.

Valid values: resolution and ratio are constrained by the model’s capability (see workflow step 3 and references/capabilities.md). See references/parameters.md for more detail. Run python scripts/create_task.py --help for full parameters.

Model list

Common model IDs (aligned with API):

• Veo 3: veo@3:normal
• Veo 3.1: [email protected]:normal, [email protected]:fast
• Sora 2: sora@2:normal, sora@2:pro
• Seedance: seedance@1:pro, seedance@1:pro_fast
• Wan 2.5: [email protected]:preview
• Vidu Q2: vidu@q2:turbo, vidu@q2:pro

See references/models.md for more models and use cases.

Error handling

• If VIDAU_API_KEY is not set, scripts exit with an error; tell the user to register at https://www.superaiglobal.com/ to get an API key, then configure it in OpenClaw.
• When API or script returns an error, relay the API message first, then use the one-sentence user message below. Reply in the user’s language.

See references/errors.md for details.

Example usage

• Generate video: User says e.g. "Generate an 8s video with Veo3 from this script" or "Generate a 10s sunset beach clip with Sora2". Agent: (optional) query_credit.py → query_models.py → validate resolution/ratio/duration/audio against model capabilities (step 3); if invalid, tell user and stop; else create_task.py --prompt "..." --resolution 720p --duration 8 --model veo@3:normal → read taskUUID → wait_task.py --task-uuid <uuid> → return video URL from output blocks or explain failure.
• Local image as first frame: User has only a local image file. Agent: upload_asset.py /path/to/image.png → read data.url from stdout → create_task.py --prompt "..." --resolution 720p --image-url "<data.url>" → then wait_task as above.
• Query credits: User says e.g. "How many Vidau credits do I have?" or "Check my Vidau balance". Agent: query_credit.py → reply with data.availableCredit (and optionally data.userId).
• Check task: User says e.g. "Is my video task done? UUID is xxx". Agent: use wait_task.py --task-uuid xxx by default → return status or video link (no need to handle DELETE_SCHEDULED_TASK). Use query_task.py only when the platform requires scheduled polling, and remove the scheduled task on terminal state via DELETE_SCHEDULED_TASK on stderr.
