亞馬遜宣佈其AI視頻模型現可生成長達兩分鐘的影片

亞馬遜最近升級了其AI視頻模型Nova Reel,現在能生成長達兩分鐘的影片。

Nova Reel於2024年12月首次推出,是亞馬遜進軍生成視頻領域的第一步。它與OpenAI、Google等公司的模型展開競爭,這個市場正在迅速變得擁擠。

根據AWS開發者倡導者Elizabeth Fuentes在一篇博客文章中的說明,最新的Nova Reel 1.1能生成具有「一致風格」的「多鏡頭」視頻。用戶可以提供最多4,000個字符的提示,以生成長達兩分鐘的視頻,這些視頻由六秒的鏡頭組成。

Nova Reel 1.1還引入了一種名為「Multishot Manual」的新模式。在這種模式下,模型可以參考一張圖片和提示,從而在視頻鏡頭的構圖上提供更多控制權。根據Fuentes的說法,給定一張分辨率為1280 x 720的圖片和一個最多512字符的提示,Multishot Manual可以生成包含多達20個鏡頭的視頻。

目前,Nova Reel僅通過AWS平台和服務提供,包括亞馬遜的AI開發套件Bedrock,客戶必須申請特別訪問。與大多數生成性AI系統一樣,對於Reel是否使用倫理的方式開發,仍然存在疑問。

視頻生成模型是通過大量視頻示例進行訓練,以「學習」這些視頻中的模式,從而生成新片段。一些公司在未獲得版權所有者或創作者的許可下,對受版權保護的視頻進行模型訓練,當這些模型「重複」受版權保護的靜態畫面時,會使模型用戶面臨知識產權訴訟的風險。

亞馬遜尚未透露Reel的訓練數據來源,也沒有提供明確的方式讓創作者選擇退出可能用於模型數據集的視頻。不過,公司表示,將根據其賠償政策,保護任何因使用其模型生成的媒體而被指控侵犯版權的AWS客戶。

評論:亞馬遜的這一新舉無疑在生成視頻技術上邁出了一大步,尤其是在多鏡頭視頻的生成上,這為創作者提供了更大的靈活性和控制權。然而,隨著技術的發展,倫理問題也愈加突出。如何確保這些模型的訓練資料不侵犯他人的版權,並尊重創作者的權益,將是未來發展的關鍵。亞馬遜需要更加透明地披露其數據來源,並設計出明確的選擇退出機制,這樣才能獲得用戶的信任,並在競爭激烈的市場中佔有一席之地。

Certainly! Here’s an enhanced, detailed, and artistic prompt tailored for an AI image generator:

---

Create a highly detailed, artistic portrait of a young East Asian woman embodying a “Imada Mio-inspired” doll-like aesthetic (精緻洋娃娃臉). She has large, sparkling round eyes full of warmth and expression, a delicate V-shaped face with soft contours, and subtly flushed, rosy cheeks. Her lips are naturally plump and softly tinted, and her facial expression combines innocence, playful energy, and a touch of flirtatiousness.

Her hair is long, dark brown, and appears tousled as if she has just awakened—soft, voluminous, and gently messy (剛睡醒的凌亂感). Stray strands fall around her delicate face and shoulders, capturing the texture and natural flow of freshly mussed morning hair.

She is dressed in an oversized, translucent white men’s button-down shirt (男友風白襯衫), with the top buttons casually undone to reveal delicate collarbones and a hint of bare skin beneath, evoking a sensual yet pure “bottomless” (下衣失蹤風格) look. The shirt drapes gracefully, with natural folds and slight translucency, enhancing the softness and allure of the scene.

The overall mood is inspired by elegant Japanese Gravure photobook aesthetics (寫真集風格), radiating a Pure & Sexy charm. Use soft, luminous, high-key natural lighting to bathe her in a gentle glow, imparting a creamy, flawless, and porcelain-like skin texture. Emulate the timeless Fujifilm PRO 400H film tones with pastel coloration, subtle pinks and blues, and a carefully balanced color palette, giving the image a dreamy and refined photographic quality. The composition should feel intimate and inviting, expertly capturing both innocence and understated seduction, with fine attention to detail and artistry. Use the original face exactly as it is, without changing a details. A stunning, very fit female model with a sun-kissed, glowing tan (hyper-realistic, high-sheen skin texture).
• Attire: A strapless, high-waisted one-piece swimsuit (or very closely cut two-piece) in a dark navy or black color with prominent white polka dots. The suit has a cutout design around the midriff and a knotted/bow detail at the bust.
• Accessories:
• An oversized straw sun hat with a wide brim, featuring a colorful striped ribbon band.
• Large, chunky yellow or gold hoop earrings with a woven/textured design.
• Hair & Makeup: Classic glamour style. Bright, bold red lipstick. Hair is pulled back or tucked under the hat.
Setting & Composition
• Background: A solid, seamless, rich mustard yellow or deep ochre/orange-yellow color, providing a warm, high-contrast backdrop.
• Prop: The model is leaning on an antique or elaborate wooden armchair or chaise lounge with ornate carvings and textured, light gold/yellow upholstery (e.g., damask or brocade).
• Pose: Confident, classic, slightly leaning into the prop, looking directly at the camera with a bright, genuine smile. Three-quarter body shot.
Style & Lighting
• Lighting: Dramatic, high-key, professional studio lighting with a strong single light source to create deep shadows and extreme highlights, especially catching the sheen on the model's skin. The lighting emphasizes a sultry, glamorous mood.
• Aesthetic: High-fashion editorial, Pin-up, Retro 1950s Glamour, Vintage Summer.
• Keywords/Details: Hyper-detailed, photorealistic, cinematic lighting, rich texture, high contrast, high sheen. Prompt:

Use my image upload (keep original face) I wearing a black beanie, a black jacket, black pants, and black boots, holding a phone in his hand. He is sitting on a low wall or bench outdoors at night, with blurry city lights in the background creating a bokeh effect.
