2026年1月のアップデートにより、Veo 3.1は主要なAI動画生成ツールとして初めてネイティブ4K出力に対応しました。2026年3月に終了するまで1080pが上限だったOpenAIのSora 2を上回ります。また、音声に完全対応した初のIngredients to Videoパイプラインも導入され、キャラクターの一貫したシーンを、同期した音声付きでひとつのワークフローで生成できるようになりました。
Slow tracking shot from behind, a woman in a white linen jacket walks through a misty redwood forest at dawn. Shafts of golden light cut through the canopy. Camera stays low, tracking her at hip height. Her pace is unhurried and deliberate. Cinematic 2.39:1 ratio, desaturated greens, warm skin tone preservation, analog film grain.
Wide establishing shot. A lone lighthouse on a jagged coastal cliff at the moment before sunrise. The sea below churns with slow heavy swells. The lighthouse beam sweeps once across the frame. No people. Muted teal and slate color palette. Heavy atmospheric fog rolls in from the left. Cinematic, 24fps feel, wide angle lens, static shot.

Medium shot. A woman in her mid-thirties stands behind a busy kitchen counter at 6am, methodically grinding coffee. Her posture is focused but relaxed. Natural morning light from a window to her left. The kitchen is lived-in and warm. Camera holds still. No dialogue. Ambient noise: the grinder runs, distant street sounds outside. Authentic and unhurried.
Extreme close-up. A glass skincare serum bottle on a cool marble surface. A single droplet of amber liquid falls in slow motion from the dropper tip and hits the marble. The ripple spreads in sharp detail. Backlit setup, warm amber tones refracted through the glass. No text. No background elements. The product is the entire frame.
Low angle tracking shot. An athlete in a dark navy seamless running set sprints along an empty coastal road at sunrise. Camera angle sits at ankle height, tracking forward alongside. Motion blur on the road surface. Sharp detail on the fabric and stride. Breathing audible. Footfalls rhythm on asphalt. Warm orange backlight, lens flare at the horizon, no voiceover.
Animate this product image. The camera performs a slow orbital move clockwise around the product, starting at the front left and completing a 90-degree arc. The product rotates slightly on its axis as the camera moves. Soft rim lighting from behind catches the edge of the packaging. No background change. No people enter the frame. Ambient audio: subtle product-specific texture sound.
Animate this portrait. The subject turns their head very slightly to the right and a faint smile forms over 3 seconds. Hair moves minimally as if in a light indoor breeze. Eyes are alive and present. Camera holds completely still. Warm studio lighting maintained from the source image. No dramatic changes. Subtle, natural, and human.

Animate this interior photograph. Light from the window shifts slowly as if a cloud passes outside. The curtain sways gently. A candle on the table flickers. Nothing else moves. Camera holds static. Ambient audio: distant street sounds, faint birdsong through the open window. The scene breathes without anyone entering it.
機能3:Ingredients to Video
Ingredients to Videoは、Veo 3.1で商業的に最も重要な機能です。AI動画を実際の制作現場で使えなくしていた問題、つまり人物の同一性のブレを解決します。
参照画像がないと、AIが生成するキャラクターはショットごとに顔、服装、体型が変わってしまいます。シーン1ではある見た目だったキャラクターが、シーン3では親戚のような別人になってしまうのです。Ingredients to Videoでは、生成の軸となる参照画像を最大4枚までアップロードできるため、この問題がなくなります。あなたのキャラクターはあなたのキャラクターのまま、商品は商品のまま、ビジュアルスタイルも一貫して保たれます。
2026年1月のアップデートで、Ingredients to Videoは音声に完全対応しました。キャラクターが一貫したシーンに、同期したセリフ、環境音、効果音も加わります。ひとつの機能で完結する、完全な制作パイプラインです。
