About aliyun-videoretalk

aliyun-videoretalk is a skill for using Model Studio VideoRetalk to match an existing person video to a new speech track. It supports workflows that submit and track asynchronous video-processing tasks.

Key features

  1. 01Replace lip sync with a new audio track
  2. 02Select a target face in multi-face video
  3. 03Extend video to match longer audio
  4. 04Submit and poll asynchronous tasks

Use cases

  1. 01Replace dialogue or narration in a person video
  2. 02Process video containing multiple faces
  3. 03Match video duration to a longer audio track

Install

Copy the command and run it in a terminal.

$npx skills add https://github.com/cinience/alicloud-skills --skill aliyun-videoretalk

After installing, type/aliyun-videoretalkin Claude Code to confirm it loaded.

Category: provider

Model Studio VideoRetalk

Validation

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

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.
