Model Studio Emoji

Validation

bash

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

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

Output And Evidence

• Save normalized request payloads, detected face boxes, selected template ID, and task polling snapshots under output/aliyun-emoji/.
• Record the exact portrait URL and whether detection passed.

Use Emoji when the user wants a fixed-template facial animation clip rather than open-ended video generation.

Critical model names

Use these exact model strings:

• emoji-detect-v1
• emoji-v1

Selection guidance:

• Run emoji-detect-v1 first to obtain face_bbox and ext_bbox_face.
• Use emoji-v1 only after detection succeeds.

Prerequisites

• China mainland (Beijing) only.
• Set DASHSCOPE_API_KEY in your environment, or add dashscope_api_key to ~/.alibabacloud/credentials.
• Input image must be a public HTTP/HTTPS URL.

Normalized interface (video.emoji)

Quick start

bash

python skills/ai/video/aliyun-emoji/scripts/prepare_emoji_request.py \
  --image-url "https://example.com/portrait.png" \
  --face-bbox 302,286,610,593 \
  --ext-bbox-face 71,9,840,778 \
  --template-id emoji_001

Operational guidance

• Use a single-person, front-facing portrait with no face occlusion.
• Template IDs come from the official template list or console experience; do not invent them in production calls.
• Emoji output is a person video clip, not a sticker pack or text overlay asset.

Output location

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