Vidu 2 视频生成大模型，平衡速度与质量，主攻图生视频、首尾帧功能，支持 4 秒时长下 720P 分辨率输出。生成速度大幅提升，成本显著降低；图生视频修复变色问题，画面稳定可控适配电商等场景，首尾帧语义理解与多参考图一致性增强，成为泛娱乐、互联网、动漫短剧、广告量产的高效工具。

​

图生视频

curl --location --request POST 'https://geekai.co/api/v1/videos/generations' \
--header 'Content-Type: application/json' \
--header 'Authorization: Bearer $GEEKAI_API_KEY' \
--data '{
    "model": "vidu-2",
    "prompt": "让画面动起来",
    "image": "https://img.iplaysoft.com/wp-content/uploads/2019/free-images/free_stock_photo.jpg",
    "size":"1280x720",
    "with_audio": true,
    "extra_body": {
        "movement_amplitude": "auto"
    }
}'
响应是一个 JSON 对象，包含生成图片的 URL： 
{
    "model": "vidu-2",
    "task_id": "cc8ba53a-2be5-4a1e-a5db-a224b69d5a49",
    "task_status": "succeed",
