Video Generate

Use Cases

Use this skill when you need to generate a video based on a text description. It supports controlling the video's starting frame through a first-frame image, which can be a URL or a local file path.

Steps

Prepare the target filename (e.g. output.mp4) and a clear and specific prompt。
(Optional) Prepare a first-frame image, which can be an HTTP URL or a local file path (the script will automatically convert it to Base64).
Run the script python scripts/video_generate.py <filename> "<prompt>" [first_frame]. Before running, cd to the corresponding directory.
The script will output the video's TOS URL and automatically download it to the specified file.

Authentication and Credential Sources

Preferentially read the MODEL_VIDEO_API_KEY or ARK_API_KEY environment variables.
If not configured, it will attempt to use VOLCENGINE_ACCESS_KEY and VOLCENGINE_SECRET_KEY to obtain the Ark API Key.

Output Format

The console outputs the generated video URL.
The video file will be downloaded to the specified path.

Examples

Text-only generation:

python scripts/video_generate.py "cat.mp4" "一只可爱的猫"

Generation with a first-frame image (URL):

python scripts/video_generate.py "dog_run.mp4" "一只小狗在草地上奔跑" "https://example.com/dog_start.png"

Generation with a first-frame image (local file):

python scripts/video_generate.py "my_video.mp4" "图片中的人物动起来" "/path/to/local/image.jpg"
