Seedance 2.5 AI 影片生成器：你的線上影片工作室

The Seedance 2.5 AI video generator supports text-to-video and image-to-video. You can start from a prompt, or upload a reference image to preserve subject, framing, and style, then set model, audio, resolution, aspect ratio, and duration.

Yes. Generated results stay in the workspace, so you can adjust the prompt, reference image, model, aspect ratio, duration, resolution, or audio toggle and generate again. It works as an iterative AI video workspace rather than a traditional timeline editor.

The workspace is designed for short-form generation, with common landscape, vertical, and square formats such as 16:9, 9:16, and 1:1, plus 4 to 15 second duration controls. Available resolutions depend on the selected model and plan rules, making it practical to preview first and then create a sharper publishable version.

Paid plans are intended for commercial content workflows such as ads, product showcases, social content, and brand videos. You still need the proper rights for any reference images, likenesses, trademarks, music, or other uploaded materials you use.

When audio is enabled, the generation task submits the visual rhythm, scene mood, and audio intent together so the result better fits shorts, ads, and social content. You can also turn audio off and generate a visual-only video for later music or voiceover work.

The workspace estimates the required credits before submission and checks your account balance. If credits are insufficient, you can reduce duration, lower resolution, switch to Fast mode, buy a credit pack, or upgrade your subscription.
