模型比較
Gemini Omni Flash 1.2 vs 1.1
Omni Flash 1.2 vs 1.1 實測，我們用相同的五組提示詞，讓兩版並排較量。尺寸相同、長度相同，各生成一次，接著再試新功能。
試用 Gemini Omni Flash 1.2先看結論
- 1.2 透過提示詞生成的片段，長度上限從 10 秒提升到 15 秒。
- 現在可以編輯最長 15 秒的片段，編輯時也能加入照片。
- Keep editing 讓你用新提示詞修改已完成的片段，修一個細節，不必整段重做。
- 使用相同提示詞，兩版品質差不多。產品攝影由 1.1 勝出，其餘平手。
- 每秒價格不變。

產品攝影
這局 1.1 勝出。鏡頭繞著場景移動，玻璃壺也全程維持玻璃材質。1.2 的鏡頭幾乎沒動，壺一開始是綠色，之後才變成玻璃。下方的 Keep editing 示範，一步就修好了這個問題。
A matte sage-green ceramic pour-over coffee set sits on a pale oak counter in soft morning window light. The camera makes one slow orbit around the set as hot water streams from a gooseneck kettle into the dripper and coffee gathers in the glass carafe below. Steam rises and catches the light. Keep the product shape, glaze texture and proportions identical throughout. Quiet kitchen ambience, gentle pouring sound, no music, no text, no logos.
雙人對話
平手。兩版都清楚說出女方的台詞，人物臉部和咖啡廳也都自然。但兩版都沒能在 8 秒內放進男方的回話。想完成兩句對話，就把片段拉長。
Two friends sit at a small table in a busy cafe, medium shot. The woman leans in and says, "You actually quit your job today?" The man laughs, shrugs and answers, "I start the bakery on Monday." Natural cafe chatter, cups clinking, warm afternoon light, handheld documentary feel.
從照片開始
表現接近。兩版都保留了她的臉、灰色短髮、牛仔外套和金色耳環，也都有把頭髮撥到耳後的動作。由於提示詞提到街道，兩版都在第一秒就把她從照片中的素色牆前移到街上。
She turns her head toward the camera, smiles and tucks her hair behind her ear as a breeze moves through the street. Keep her face, denim jacket and gold earrings exactly as in the image. Soft city ambience, slow push-in.
參考照片中的產品
平手。兩版都保留了琥珀色玻璃、黑色滴管和簡潔標籤，也都有手拿起瓶子、轉動再放下的動作。1.2 在檯面多加了一塊亞麻布。
The serum bottle from the first image stands on the marble counter of the kitchen in the second image. A hand reaches in, picks it up, and turns it so the label faces the camera, then sets it back down in the morning light. Keep the bottle shape, color and label identical to the reference. Soft room tone, a light glass tap on marble.
編輯片段：雨景變雪景
兩版幾乎一樣。雨變成雪，積在街道上，行人和運鏡則維持原樣。
Keep everything the same, but turn the rain into gently falling snow, with snow settling on the umbrella and the street.
新功能
前兩項僅限 1.2 使用。第三項則是工具頁面上的新按鈕。
15 秒一鏡到底
1.1 stops at 10 seconds. 1.2 makes text-to-video clips up to 15 seconds.
三個時刻，一鏡到位：麵包店鐵捲門升起、市場攤位陸續擺設，以及日出時的橋。
One continuous shot following a cyclist through a narrow old European street at sunrise: she rides past a bakery as the owner lifts the shutter, turns a corner into a market where stalls are being set up, and rolls out onto a bridge as the sun clears the rooftops. Bicycle bell, footsteps, distant church bells, birds. Smooth tracking camera at handlebar height.
用參考照片編輯片段
1.2 新功能。編輯時加入照片，就能把照片中的人物、產品或穿搭帶進片段。
行人換成照片中的女子，穿著牛仔外套、留著灰色短髮。街道、雨景和運鏡都維持原樣。她背對鏡頭走遠，因此看不到臉，雨傘也直到接近結尾才重新出現。
Replace the person under the umbrella with the woman from the image, wearing the same denim jacket and gold earrings. Keep the street, the rain and the camera move the same.
用 Keep editing 繼續修改同一片段
在任一生成結果按下 Keep editing，描述你想改的地方。這裡我們修正了頁面上方的產品攝影片段。
水壺變成髮絲紋銅色，光線也更暖。編輯後，玻璃壺全程維持玻璃材質，修好了第一次生成時的失誤。
Keep everything the same, but change the kettle to brushed copper and make the window light warmer.
