description: "Generate videos using Wan models. Supports text-to-video, image-to-video, first+last frame, reference-based role-play, and video editing (VACE). TRIGGER when: user wants to create, generate, or edit video content, mentions video generation/animation/video clips/Wan models, or explicitly invokes this skill by name (e.g. use qwencloud-video-generation). DO NOT TRIGGER when: user wants to generate images (use qwencloud-image-generation), understand/analyze existing videos (use qwencloud-vision), text-only tasks."

# Qwen Video Generation

Generate videos using Wan models. All tasks are **asynchronous** — submit, then poll until
completion.
This skill is part of **qwencloud/qwencloud-ai**.

> **⚠️ Critical Parameter Differences:**
> - **kf2v (First+Last Frame)**: Duration is **fixed at 5 seconds** — other values will fail. Output is **silent only**.
> - **Resolution parameters vary by model family, not mode alone**: Fetch the current model catalog before choosing `size`, `resolution`, or `ratio`.

## Skill directory

Use this skill's internal files to execute and learn. Load reference files on demand when the default path fails or you need details.

## Security

**NEVER output any API key or credential in plaintext.** Always use variable references (`$QWENCLOUD_API_KEY` in shell, `os.environ["QWENCLOUD_API_KEY"]` in Python). The scripts accept `QWENCLOUD_API_KEY`, then `QWEN_API_KEY`, then `DASHSCOPE_API_KEY`. Any check or detection of credentials must be **non-plaintext**: report only status (e.g. "set" / "not set", "valid" / "invalid"), never the value. Never display contents of `.env` or config files that may contain secrets.

**When the API key is not configured, NEVER ask the user to provide it directly.** Instead, help create a `.env` file with a placeholder (`QWENCLOUD_API_KEY=sk-your-key-here`) and instruct the user to replace it with their actual key from the [QwenCloud Console](https://home.qwencloud.com/api-keys). Only write the actual key value if the user explicitly requests it.

## Key Compatibility

Scripts support both **standard QwenCloud API keys** (`sk-...`) and **Token Plan keys** (`sk-sp-...`). Token Plan keys are automatically routed to the Token Plan endpoint for supported video models — see [Token Plan Support](#token-plan-support) below.

**Token Plan: do not use curl; always use the bundled Python script.**

Coding Plan keys (also `sk-sp-` prefix but purchased via Coding Plan subscription) cannot be used — video generation models are not available on Coding Plan. Video generation incurs per-second charges on standard keys. The script detects key type at startup and routes accordingly. If qwencloud-ops-auth is installed, see its `references/codingplan.md` for full details.

Detect the API key type without exposing the key:

```bash
python3 -c "
import sys; sys.path.insert(0, 'scripts')
from qwencloud_lib import detect_api_key_type
print(detect_api_key_type('scripts/qwencloud_lib.py'))
"
```
