Product Commercial
The character in the painting looks guilty, darting glances left and right before leaning out of the picture frame. Very swiftly, they extend a hand outside the frame, grab a cola, take a sip, and reveal a look of deep satisfaction. Hearing footsteps approach, the character hastily puts the cola back just as a Western cowboy walks by and picks it up. The ending shot pushes in on a top-lit close-up of the cola against a pure black background, with artistic subtitles and a voiceover appearing at the bottom: "Yikou Cola, an absolute must-try!"
Extend the Video Length
Extend the video length. The camera follows a man in orange riding a brown horse. He speeds up and gallops to a large tree with orange flowers ahead, breaks off two blossoms from the branch. Then others ride into the frame one after another. The camera pushes in to shoot the man in orange clothes dismounting from the horse, then the camera quickly circles around him. He turns to walk toward a woman in white riding a white horse and presents the flowers to her. Style: Chinese classical lady painting, 3D, cheerful folk music, shadow puppet style, with black, white, and orange as the main color palette.
Multimodal All-Round Reference
Refer to the shooting script in @Image 1, and draw on the storyboard, shot scale, camera movement, visuals and copy in @Image 1. The character is from @Image 2, the scene is from @Image 3, and the props are from @Image 4. Create a 15-second healing short film.
Wuxia-Style Audiovisual Blockbuster
A Wuxia-style audiovisual blockbuster. A white-clad swordsman and a straw-caped blademaster face off in a bamboo forest. The camera slowly pushes in between them, shifting focus between raindrops and sword hilts. The atmosphere is extremely oppressive; only the sound of rain can be heard. Suddenly, a crack of thunder flashes, and both charge simultaneously. A fast-panning profile shot captures their mud-splattering footsteps. The precise moment their weapons clash, the footage switches to ultra-slow motion, clearly displaying the ring-shaped shockwaves of rainwater blasted away by the blades, along with bamboo leaves sliced by sword aura. Normal speed resumes as they land back-to-back. The straw-caped blademaster's bamboo hat splits open, and the scene cuts abruptly.
1920s Jazz Club Charleston Dance
1920s jazz club-style Charleston dance. A female dancer in a gold fringe dress and a male dancer in a striped suit perform a high-intensity routine. Moves include hyper-fast syncopated footwork, aerial catches, and exaggerated arm swings. The camera uses dynamic tracking, interspersed with close-ups of footwork. Emphasis is on physical details the fringe swinging wildly with every kick, the sheen of sweat on their skin, and the smoky, vintage film grain cinematic texture. A background jazz band and cheering audience amplify the frenzied party atmosphere.
Girl Hangs Laundry Gracefully
A girl hangs laundry gracefully. After finishing, she takes another piece of clothing from the bucket and shakes it vigorously.
Seedance 2.0 核心能力
了解 Seedance 2.0 的输入方式、生成控制和适用工作流
四模态AI视频生成
不同于仅支持文本和图片输入的Seedance 1.5 Pro，Seedance 2.0接受四种输入模态 —— 文本提示、图片、音频文件和视频片段。同时上传最多15个参考文件，精确控制AI视频生成结果。
原生音视频联合生成
在所选模式支持时，Seedance 2.0 可随视频生成同步音频，包括对白、音效和背景音。
定向视频编辑
Seedance 2.0为AI视频引入定向编辑功能 —— 替换特定角色、修改个别场景或延长片段，无需重新生成整个视频。Seedance 1.5 Pro每次修改都需要完整重新生成。
分镜脚本转视频
上传分镜脚本或拍摄计划作为参考图片，Seedance 2.0将遵循镜头尺度、镜头运动和视觉构图。AI视频生成器自动将你的创作方向转化为精美视频。
运动与场景动态
Seedance 2.0 适合包含重力、流体、布料和多主体运动的场景。输出质量取决于提示词、参考素材和生成设置。
角色与场景一致性
通过参考素材和详细提示词，引导多个镜头中的角色身份、服装与环境保持一致。实际一致性会因场景和素材而异。
