使用 Seedance 2.5 创建更长、更可控的 AI 视频
如果您想探索一种更易于控制的 AI 视频创作方法，可以免费试用Seedance 2.5 。
Seedance 2.5 不再仅仅依靠文本提示来生成短片，而是将更长的视频生成、多模态参考和精确的 AI 视频编辑结合在一个工作流程中。
创作者可以生成最长 30 秒的视频，并使用最多 50 个图像、视频和音频参考来指导角色、产品、环境、动作和视觉风格。
这使得 Seedance 2.5 对广告、动画、产品视频、短视频内容和电影制作来说特别有吸引力。
为什么30秒AI视频生成如此重要
许多人工智能视频工作流程都是围绕短小的单个视频片段构建的。
这对于简单的概念来说行得通，但是当你想要创建一个包含多个相互关联动作的完整序列时，就会变得更加困难。
Seedance 2.5 支持连续生成长达 30 秒的视频。
更长的生成周期可以让创作者有足够的时间来开发诸如以下这样的序列：
• 营造氛围
• 介绍角色或产品
• 将镜头移向拍摄对象
• 展示动作或互动
• 展示产品细节
• 过渡到最终的电影镜头
例如，对于产品广告，视频可以以一个广角场景镜头开始，然后过渡到产品特写，最后以产品在真实环境中的使用场景结束。
优势不仅仅在于拥有“更多的时间”，更在于在同一个创意序列中拥有更大的空间来发展动作和视觉连贯性。
使用多达 50 个多模态参考构建视频
Seedance 2.5 最重要的功能之一是支持跨图像、视频和音频的多达 50 个多模态参考。
与其用文字描述每一个视觉要求，创作者可以提供参考资料，说明重要元素应该是什么样子或感觉起来是什么。
参考文献可用于：
• 角色和面孔
• 产品和物品
• 服装和配饰
• 环境和地点
• 视觉风格
• 动作和运动
• 镜头方向
• 现有视频参考
• 音频参考
这使得工作流程从简单的提示到视频生成，转变为更接近参考资料驱动的视频制作。
文本转视频，更具创意控制
文本转视频仍然是 Seedance 2.5 的重要组成部分。
提示可以描述主题、环境、动作、光线、氛围和镜头运动。
例如，与其这样写：
一位女士手持香水瓶。
更注重生产效率的提示可以这样定义：
“A cinematic luxury perfume commercial. A woman in an elegant black dress walks slowly through a softly lit hotel lobby while holding a glass perfume bottle. The camera tracks alongside her before moving into a close-up product shot. Warm cinematic lighting, realistic reflections, shallow depth of field.”
The additional structure gives the model clearer information about how the scene should develop.
When working with longer generations, it can also help to think about the prompt as a timeline rather than a single static description.
Image-to-Video for Products and Characters
Image-to-video becomes especially useful when the visual identity of a subject already exists.
Instead of asking AI to invent a product or character from scratch, creators can provide an image reference and focus the prompt on motion, camera direction and scene development.
This can be useful for:
• Ecommerce products
• Fashion items
• Character animation
• Advertising creatives
• Product launches
• Social media campaigns
For product videos, maintaining recognizable design details is particularly important.
Reference-driven generation can help creators communicate the intended appearance more clearly than text alone.
Precise AI Video Editing
Generating the first video is only part of the creative process.
In real production, revisions are normal.
A client may like the camera movement but want a different object. A character may look correct while the environment needs adjustment. A product shot may work except for one visual detail.
Seedance 2.5 includes precise AI video editing capabilities designed for this type of iterative workflow.
Instead of treating every change as a completely new generation, creators can focus on refining specific elements while preserving useful parts of the existing scene.
That can be particularly valuable for professional creative work where multiple revisions are expected.
High-Fidelity Character and Product Consistency
Consistency is one of the biggest challenges in longer AI-generated videos.
Characters can gradually change appearance. Products can lose important details. Clothing, environments or objects may shift unexpectedly as the video progresses.
Seedance 2.5 uses multimodal reference control to provide stronger guidance for these elements.
For character-driven animation, this can help maintain identity and appearance.
For advertising and ecommerce, it can help preserve recognizable product characteristics throughout the scene.
The more important a subject is to the final video, the more useful strong reference materials become.
Realistic Motion and Cinematic Camera Work
A good AI-generated frame does not automatically produce a good AI-generated video.
Motion matters.
Human movement, object interaction, environmental dynamics and camera behavior all influence whether a scene feels believable.
Seedance 2.5 is designed for realistic motion and cinematic visual presentation, opening up workflows involving:
• Tracking shots
• Slow camera pushes
• Product close-ups
• Character movement
• Environmental motion
• Cinematic reveals
• Continuous camera sequences
• Commercial-style compositions
For advertising and filmmaking, camera language can be just as important as the subject itself.
Seedance 2.5 for AI Advertising
Advertising is one of the clearest use cases for a reference-driven AI video workflow.
Brands often already have product images, campaign references, visual guidelines and examples of the style they want.
These materials can become part of the generation process.
Seedance 2.5 can be used to explore:
• Product commercials
• Social media advertisements
• Ecommerce videos
• Brand campaigns
• Product demonstrations
• Promotional films
• Creative concept testing
The ability to combine longer scenes with product references makes it easier to develop more structured advertising concepts.
Seedance 2.5 for Anime and Animation
Animation creators have a different consistency problem: characters and worlds need to remain recognizable.
Character references can establish appearance, while environment and style references can help communicate the intended visual direction.
Potential workflows include:
• Anime-style scenes
• Character animation
• Animated short videos
• Music video concepts
• Story visualization
• Animated advertisements
• Cinematic concept sequences
For creators developing recurring characters, reference control becomes particularly important.
Seedance 2.5 for Filmmaking and Previsualization
AI video can also be useful before traditional production begins.
Filmmakers can use generated video to explore ideas for:
• Camera movement
• Character blocking
• Lighting
• Locations
• Production design
• Action sequences
• Trailer concepts
• Storyboards and previsualization
The goal does not necessarily have to be replacing traditional filmmaking.
Instead, AI video can provide a faster way to visualize a concept before committing significant production resources.
1080P and 4K Production Workflows
Professional video rarely ends when the AI generation finishes.
Generated footage may still move through editing, sound design, graphics, color work and other post-production processes.
Seedance 2.5 can fit into 1080P and 4K production workflows, making it useful for creators who want to take generated material beyond quick experiments and into more polished content.
This is particularly relevant for advertising, product videos, promotional films and professional cinematic projects.
