# Model Studio LivePortrait

## Validation

```bash
mkdir -p output/aliyun-liveportrait
python -m py_compile skills/ai/video/aliyun-liveportrait/scripts/prepare_liveportrait_request.py && echo "py_compile_ok" > output/aliyun-liveportrait/validate.txt
```

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

## Output And Evidence

- Save normalized request payloads, template choice, and task polling snapshots under `output/aliyun-liveportrait/`.
- Record the exact portrait/audio URLs and motion-strength related parameters.

Use LivePortrait when the job is lightweight portrait animation with speech audio, especially for longer clips or simpler presenter-style motion.

## Critical model names

Use these exact model strings:
- `liveportrait-detect`
- `liveportrait`

Selection guidance:
- Run `liveportrait-detect` first to verify the portrait image.
- Use `liveportrait` for the actual video generation task.

## Prerequisites

- China mainland (Beijing) only.
- Set `DASHSCOPE_API_KEY` in your environment, or add `dashscope_api_key` to `~/.alibabacloud/credentials`.
- Input image and audio must be public HTTP/HTTPS URLs.

## Normalized interface (video.liveportrait)

### Detect Request
- `model` (string, optional): default `liveportrait-detect`
- `image_url` (string, required)

### Generate Request
- `model` (string, optional): default `liveportrait`
- `image_url` (string, required)
- `audio_url` (string, required)
- `template_id` (string, optional): `normal`, `calm`, or `active`
- `eye_move_freq` (number, optional): `0` to `1`
- `video_fps` (int, optional): `15` to `30`
- `mouth_move_strength` (number, optional): `0` to `1.5`
- `paste_back` (bool, optional)
- `head_move_strength` (number, optional): `0` to `1`

### Response
- `task_id` (string)
- `task_status` (string)
- `video_url` (string, when finished)

## Quick start

```bash
python skills/ai/video/aliyun-liveportrait/scripts/prepare_liveportrait_request.py \
  --image-url "https://example.com/portrait.png" \
  --audio-url "https://example.com/speech.mp3" \
  --template-id calm \
  --video-fps 24 \
  --paste-back
```

## Operational guidance

- Use a clear, front-facing portrait with low occlusion.
- Keep the audio clean and voice-dominant.
- `paste_back=false` outputs only the generated face region; keep it `true` for standard talking-head output.
- LivePortrait is a better fit than EMO when you need longer, simpler presenter-style clips.

## Output location

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

watch

Included

Watch a video (URL or local path). Downloads with yt-dlp, extracts auto-scaled frames with ffmpeg, pulls the transcript from captions (or Whisper API fallback), and hands the result to Claude so it can answer questions about what's in the video.

humanizer

Included

Humanize AI-generated text by detecting and removing patterns typical of LLM output. Rewrites text to sound natural, specific, and human. Uses 28 pattern detectors, 560+ AI vocabulary terms across 3 tiers, and statistical analysis (burstiness, type-token ratio, readability) for comprehensive detection. Use when asked to humanize text, de-AI writing, make content sound more natural/human, review writing for AI patterns, score text for AI detection, or improve AI-generated drafts. Covers content, language, style, communication, and filler categories.
