Video Generate

适用场景

当需要根据文本描述生成视频时，使用该技能。支持通过首帧图片控制视频起始画面，首帧可以是 URL 或本地文件路径。

使用步骤

  1. 准备目标文件名（如 output.mp4）和清晰具体的 prompt。
  2. (可选) 准备首帧图片，可以是 HTTP URL，也可以是本地文件路径（脚本会自动转为 Base64）。
  3. 运行脚本 python scripts/video_generate.py <filename> "<prompt>" [first_frame]。运行之前cd到对应的目录。
  4. 脚本将输出视频的 TOS URL 并自动下载到指定文件。

认证与凭据来源

  • 优先读取 MODEL_VIDEO_API_KEY 或 ARK_API_KEY 环境变量。
  • 若未配置，将尝试使用 VOLCENGINE_ACCESS_KEY 与 VOLCENGINE_SECRET_KEY 获取 Ark API Key。

输出格式

  • 控制台输出生成的视频 URL。
  • 视频文件将被下载到指定路径。

示例

纯文本生成：

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

带首帧图片生成（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"

带首帧图片生成（本地文件）：

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