## What it does

The skill triggers `scripts/generate_video.py` to communicate with the Volcengine Jimeng Video 3.0 Pro API. It submits asynchronous generation tasks via `CVSync2AsyncSubmitTask`, polls for completion, and returns a direct link to the resulting MP4. Supported modes cover text-to-video and image-to-video workflows in 720p and 1080p, plus the `ti2v_pro` option.

Valid credentials are mandatory: `VOLC_ACCESSKEY` and `VOLC_SECRETKEY` must be configured in your environment. Without them, IAM v4 request signing fails immediately. You can control duration between 4 and 10 seconds, choose 24, 25, or 30 FPS, and pass a random seed for reproducible outputs.

Source images must be JPEG or PNG files up to 15MB with a maximum resolution of 4096×4096. Generation typically takes 2 to 10 minutes. The resulting download link remains valid for 24 hours.
