對經常使用 AI 生成影片的創作者來說,最熟悉的挫折莫過於故事正要進入高潮時,畫面卻戛然而止。如今,Google 希望改善這個問題。該公司正式推出新一代 AI 影音生成模型 Gemini Omni 1.2 Flash,不僅延長影片生成時長,也進一步強化後製編輯與畫面一致性能力,讓 AI 影片創作流程更貼近專業製作需求。

Gemini Omni 1.2 Flash 讓 AI 影片生成變得更長、更便宜也更容易編輯
相較於前代 Omni 1.1 僅支援最長 10 秒的影片輸出,Gemini Omni 1.2 Flash 將生成時長提升至 15 秒,使用者還能在 3 至 15 秒之間自由選擇影片長度,並以 1 秒為單位進行調整。雖然距離完整的短影音廣告或品牌敘事仍有一段距離,但對創作者而言,影片時長增加 50%,已能有效提升情節鋪陳與鏡頭表現空間。
Today we are rolling out Gemini Omni Flash 1.2, with: – longer video generation (15 seconds) – deeper cinematic controls for camera pov – support for multi-turn conversation editing – less visual drift – 30% lower price than Omni Flash 1.1 Read more: https://t.co/U0VgGTGcmW

然而,真正值得關注的升級並非只有片長。Google 將更多心力放在影片編輯體驗上,讓使用者能透過自然語言與 AI 模型互動,直接調整影片中的背景、天氣效果、場景元素,甚至重新設定畫面比例,而不必從頭生成整段影片。這項能力大幅降低反覆重製內容的成本,特別是在只需修正單一細節的情況下,更能節省大量運算資源與時間。
在內容一致性方面,Gemini Omni 1.2 Flash 也展現顯著進步。使用者只需提供特定角色、產品或品牌素材圖片,再搭配最長三秒的音訊提示或動作參考片段,系統便能在不同鏡頭之間維持服裝、包裝設計、品牌色彩等視覺元素的一致性,避免 AI 影片常見的人物外觀漂移或品牌識別錯亂問題。

影片品質同樣有所提升。Google 表示,新模型能更自然地呈現無人機空拍、環繞運鏡等複雜鏡頭運動,降低畫面切換時的突兀感。同時,在人物對話場景中,唇形同步準確度也獲得改善,即使是多角色對話,多聲部聲音的辨識度與分離效果也更加清晰。
價格方面,Google 將 Omni 1.1 的生成成本下調 30%,720p 解析度影片每秒僅需 0.07 美元。以此計算,一支完整的 15 秒影片生成費用約為 1.05 美元。目前官方尚未公布 1080p 或 4K 版本的定價策略,但對創作者而言,先以較低解析度完成初版內容,再將最終成品升級至高畫質輸出,仍是兼顧成本與效率的實務做法。
Meet Gemini Omni 1.2 Flash ⚡️ We’ve made the model more cost-effective, bumped the video generation and editing limit up to 15 seconds, and made updates to how scenes hold together over time. We’ve also given character speech an upgrade, reduced visual glitches like jump cuts, and made sure the model stays even truer to any reference assets you upload. So… what does all of that actually mean for you? It gives you more room to tell your story. With up to 15 seconds to work with, you have more flexibility to create what you need — videos look more cinematic and smooth, offering stronger consistency that keeps objects anchored from start to finish. And when characters speak, the dialogue sounds more fluid and natural. Creators and everyday users can start directing scenes and multi-turn edits in @FlowbyGoogle, generating 15-second clips at no additional cost in Google Vids, or creating 15-second videos in the @GeminiApp. Plus, for developers and businesses building with the API, we’ve dropped the price by 30% from the previous generation, making it available at just $0.07 per second for 720p video.

在部署與使用管道上,開發者可透過 Google AI Studio 與 Gemini API 存取 Gemini Omni 1.2 Flash,企業用戶則能在 Google Cloud 平台透過預留運算資源進行規模化應用。此外,Flow、Google Ads 與 Google Vids 等服務也已整合這項技術。一般使用者只要擁有 Google 帳戶或 Workspace 訂閱,即可免費體驗最長 15 秒的 AI 影片生成,而訂閱 AI Ultra 方案的用戶,則能直接在 Gemini 應用程式中使用相關功能。
隨著影片長度、編輯能力與內容一致性同步升級,Gemini Omni 1.2 Flash 顯示 Google 正積極縮短 AI 生成內容與專業影音製作之間的距離,也讓 AI 影片創作邁向更實用的新階段。
