Model Studio Digital Human

Validation

mkdir -p output/aliyun-wan-digital-human
python -m py_compile skills/ai/video/aliyun-wan-digital-human/scripts/prepare_digital_human_request.py && echo "py_compile_ok" > output/aliyun-wan-digital-human/validate.txt

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

Output And Evidence

• Save normalized request payloads, chosen resolution, and task polling snapshots under output/aliyun-wan-digital-human/.
• Record image/audio URLs and whether the input image passed detection.

Use this skill for image + audio driven speaking, singing, or presenting characters.

Critical model names

Use these exact model strings:

• wan2.2-s2v-detect
• wan2.2-s2v

Selection guidance:

• Run wan2.2-s2v-detect first to validate the image.
• Use wan2.2-s2v for the actual video generation job.

Prerequisites

• China mainland (Beijing) only.
• Set DASHSCOPE_API_KEY in your environment, or add dashscope_api_key to ~/.alibabacloud/credentials.
• Input audio should contain clear speech or singing, and input image should depict a clear subject.

Normalized interface (video.digital_human)

Detect Request

• model (string, optional): default wan2.2-s2v-detect
• image_url (string, required)

Generate Request

• model (string, optional): default wan2.2-s2v
• image_url (string, required)
• audio_url (string, required)
• resolution (string, optional): 480P or 720P
• scenario (string, optional): talk, sing, or perform

Response

• task_id (string)
• task_status (string)
• video_url (string, when finished)

Quick start

python skills/ai/video/aliyun-wan-digital-human/scripts/prepare_digital_human_request.py \
  --image-url "https://example.com/anchor.png" \
  --audio-url "https://example.com/voice.mp3" \
  --resolution 720P \
  --scenario talk

Operational guidance

• Use a portrait, half-body, or full-body image with a clear face and stable framing.
• Match audio length to the desired output duration; the output follows the audio length up to the model limit.
• Keep image and audio as public HTTP/HTTPS URLs.
• If the image fails detection, do not proceed directly to video generation.

Output location

• Default output: output/aliyun-wan-digital-human/request.json
• Override base dir with OUTPUT_DIR.
