Seedance 2.5 Video Generator

Seedance 2.5 is an online AI video generator for finished cuts, designed to output a single continuous 30-second clip in native 4K (no stitching a second half and no upscale pass). Build a shot from a text brief, then reinforce it with multimodal references so the model follows your character, scene, motion, and style across the entire render.

Use up to 50 reference slots in one job, including images, reference videos (up to 3, up to 15s total), audio (up to 3), and a 3D white-model blockout to establish camera path and blocking. Tag each asset with roles (like character, location, motion style, or color palette) so references stay pinned to their intended parts of the scene.

Seedance 2.5 is also built for shot-level control: it supports directional language for camera and motion, native audio generation synced to the video, and practical iteration workflows where you can re-run or adjust segments (like trimming and holding) while keeping the clip’s intent consistent.

What can I generate with Seedance 2.5?

You can generate native 30-second single-shot clips in 4K from a prompt alone, or from a mix of text plus references (images, video, audio, and 3D blockouts). The output comes back as an MP4 you can preview and download in the browser.

How long is the maximum video output?

Seedance 2.5 generates videos up to 30 seconds in a single continuous render. If you need more time, you can extend by chaining extensions from an existing clip.

Does Seedance 2.5 generate native audio with the video?

Yes—audio is generated natively alongside the video. If you want a specific rhythm or sonic feel, you can also provide an audio reference track to keep it consistent across the full clip.

How many references can I use in one Seedance 2.5 brief?

On paid packs you can use up to 50 multimodal references in one job. A focused set often works better than a cluttered upload, especially if you want the model to lock onto a few key roles.

What is 3D blockout input in Seedance 2.5?

It’s a simple untextured geometry scaffold you upload as a reference so the model follows your camera path and blocking. You can export a low-poly scene from tools like Blender, Cinema 4D, Maya, or SketchUp, then describe materials and lighting in your prompt.

Is Seedance 2.5 truly native 4K, or is it upscaled?

Paid packs export native 4K rendered at that resolution rather than enlarged from a lower-resolution render. Free starter credits cap resolution at 720p with a watermark.
