虛擬人像
使用 CometAPI 中的 Kling Avatar API，從圖片產生由虛擬人像驅動的影片。使用 POST /kling/v1/videos/avatar/image2video 快速建立 image-to-video 虛擬人像。

}呼叫前準備
- 提供一個虛擬人像
image，可使用公開 URL 或原始 base64 字串 audio_id或sound_file二擇一，且只能傳送其中一個- 第一個請求請保持簡單：一張人臉圖片、一段音訊片段，以及一段可選的簡短 prompt
- 除非你明確需要更高品質的路徑，否則請先使用
mode: std
音訊來源規則
- 如果你已透過 Kling TTS 路徑產生語音，
audio_id是最簡單的方式 - 如果你已經有自己的 MP3、WAV、M4A 或 AAC 資源，可使用
sound_file - 文件指出虛擬人像音訊長度可為 2 到 60 秒
