🚀 什麼是 Grok Imagine Video？

Grok Imagine Video 是 xAI 透過 CometAPI 提供的進階影片生成與編輯 AI 模型。它可讓開發者以自然語言提示生成短篇、客製化影片，並可選擇將靜態圖片動畫化或編輯現有片段。該模型支援設定輸出長度、解析度與長寬比，並內建內容審核以確保遵循政策。

🧠Main features（Grok Imagine 的差異點）

  • 原生音訊 + 對嘴：產生同步的環境音、音效與短語音/旁白，並提供近似唇形同步。
  • 圖片→影片 / 提示編輯：可將靜態圖動畫化，或透過文字提示編輯既有素材（移除/替換物件、重定時、變更風格）。
  • 快速迭代與低延遲：為創意流程與產品原型打造，提供快速回饋迭代。
  • 生產級 API：Imagine API 提供程式化端點，支援批次生成、整合至剪輯流程與企業控管。
  • 多種「模式」/ 風格：面向使用者的模式（據報示例：Normal / Fun / Spicy 或類似預設），用以偏置輸出的風格或寬鬆程度（注意：「Spicy」模式在歷史上曾啟用 NSFW）。
Model (company)Max res (public)Max clip len (public)Native audio?優勢注意事項
Grok Imagine (xAI)720p6–15 秒Yes快速迭代、成本/延遲具優勢、整合編輯、原生音訊受限於 720p；審核相關顧慮；真實度表現因情境而異
Sora (OpenAI)720p–1080p（視等級而定）短（6–15 秒）Yes高視覺擬真度；與 OpenAI 生態整合度高價格較高；審核/控管較受限制
Veo (Google DeepMind)最高可達 1080p+短（不等）Yes強寫實度、運動穩定成本較高；公開試驗較少
Runway Gen-4.51080p+短（不等）Yes廣受創意流程採用，高擬真度成本較高；聚焦於創作工具
Vidu / Kling / Pika (various specialists)最高至 1080p短（不等）Mixed部分提供利基功能（Smart Cuts、多鏡次串接）音訊支援不一；API 成熟度各異

⚠️ 限制

  • 最大影片長度上限為 15 秒。
  • 編輯保留輸入影片長度（≤ 8.7 秒）。
  • 生成的 URL 為臨時性——請及時下載。

如何存取與整合 Grok Imagine Video

步驟 1：註冊取得 API Key

登入 cometapi.com。若您尚未成為我們的用戶，請先註冊。登入您的 CometAPI console。取得該介面的存取憑證 API Key。在個人中心的 API token 處點擊 “Add Token”，取得 Token Key：sk-xxxxx 並提交。

步驟 2：向 Grok Imagine Video API 發送請求

選擇 “grok-imagine-video” 端點發送 API 請求並設定請求內容。請求方法與請求內容可於我們網站的 API 文件取得。我們的網站也提供 Apifox 測試以供方便使用。將 <YOUR_API_KEY> 替換為您帳戶中的實際 CometAPI 金鑰。調用位置：GROK影片生成 和 影片編輯。

步驟 3：向 Grok Imagine Video API 發送請求

輸入文字或上傳圖片（您可以選擇提供來源圖片以進行動畫化）。Grok Imagine AI API 會分析您的輸入並準備可供 URL 存取的內容。同時支援文字轉影片與圖片轉影片。

來源圖片可透過以下方式提供：

  • 指向圖片的公開 URL
  • base64 編碼的 data URI（例如：data:image/jpeg;base64,<YOUR_BASE64_IMAGE>）

步驟 4：擷取並驗證結果

處理 API 回應以取得生成結果。處理後，API 會回應任務狀態與輸出資料。提交後會立即返回 request_id；使用 GET 端點檢查狀態並擷取生成的影片。影片編輯為非同步，您可能需要多次輪詢該端點直到任務完成。請及時下載。
