What it does

Aliyun Videoretalk is an agent skill from cinience/alicloud-skills. Use when replacing lip sync in existing videos with Alibaba Cloud Model Studio VideoRetalk (videoretalk). Use when creating dubbed videos, replacing narration, or synchronizing a talking-head video to a new speech track.

Its SKILL.md is about 740 tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including scripts and reference files (for example `agents/openai.yaml`, `references/sources.md` and `scripts/prepare_retalk_request.py`).

It sits in Media & Creative, covering Text to speech and voice. It works with Alibaba Cloud. The repository describes itself as: alibaba cloud skills，qwen ，wan and all skills. The licence is MIT.

When your agent uses it

Replacing lip sync in existing videos with Alibaba Cloud Model Studio VideoRetalk (videoretalk)
Creating dubbed videos
Replacing narration
Synchronizing a talking-head video to a new speech track

Example prompts

“/aliyun-videoretalk”

Requirements

Python 3
A credential in DASHSCOPE_API_KEY

What it can do on your machine

Read from SKILL.md and the folder at commit 1818263. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 1 file in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
- python
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
- dashscope.aliyuncs.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
- DASHSCOPE_API_KEY
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Aliyun Videoretalk loads about 735 tokens when it runs, and up to ~806 if it reads all its reference files. Until then it costs about 60 tokens; SKILL.md has 258 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~60
When it runs · the whole SKILL.md, loaded when a task matches: ~735
With references · SKILL.md plus every file in references/, read only if the agent opens them: ~806

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

version: 1.0.0

Category: provider

Model Studio VideoRetalk

Validation

bash

mkdir -p output/aliyun-videoretalk
python -m py_compile skills/ai/video/aliyun-videoretalk/scripts/prepare_retalk_request.py && echo "py_compile_ok" > output/aliyun-videoretalk/validate.txt

Pass criteria: command exits 0 and output/aliyun-videoretalk/validate.txt is generated.

Output And Evidence

Save normalized request payloads, target face selection settings, and task polling snapshots under output/aliyun-videoretalk/.
Record the exact video/audio input URLs and whether video_extension was enabled.

Use VideoRetalk when the input is already a person video and the job is to replace lip sync with a new speech track.

Critical model names

Use this exact model string:

videoretalk

Prerequisites

This model currently only supports China mainland (Beijing).
API is HTTP async only; there is no online console experience.
Set DASHSCOPE_API_KEY in your environment, or add dashscope_api_key to ~/.alibabacloud/credentials.

Normalized interface (video.retalk)

Request

model (string, optional): default videoretalk
video_url (string, required)
audio_url (string, required)
ref_image_url (string, optional): target face when input video contains multiple faces
video_extension (bool, optional): extend video to match longer audio
query_face_threshold (int, optional): 120 to 200

Response

task_id (string)
task_status (string)
video_url (string, when finished)
usage (object, optional)

Endpoint and execution model

Submit task: POST https://dashscope.aliyuncs.com/api/v1/services/aigc/image2video/video-synthesis/
Poll task: GET https://dashscope.aliyuncs.com/api/v1/tasks/{task_id}
HTTP calls are async only and must set header X-DashScope-Async: enable.

Quick start

bash

python skills/ai/video/aliyun-videoretalk/scripts/prepare_retalk_request.py \
  --video-url "https://example.com/talking-head.mp4" \
  --audio-url "https://example.com/new-voice.wav" \
  --video-extension

Operational guidance

Keep input videos front-facing and close enough for stable face tracking.
If the video contains multiple faces, provide ref_image_url to anchor the intended target.
If the new audio is longer than the input video, decide explicitly whether to extend the picture track or truncate the audio.
URLs must be public HTTP/HTTPS links; local file paths are not accepted by the API.

Output location

Default output: output/aliyun-videoretalk/request.json
Override base dir with OUTPUT_DIR.
