From Prompting to Directing
Direct Every Frame with Up to 50 References
Upload up to 50 reference assets, including images, video clips, audio, and style boards, and Seedance 2.5 locks your subject, scene, character, and mood to them. You set the direction, so the model follows a clear visual brief rather than guessing.
Native 30-Second Clips in One Pass
Generate up to 30 seconds in a single pass, with scene changes and tempo shifts built in. You get one continuous clip that is easier to review, edit, and publish, rather than a chain of short shots joined at visible seams.
Characters and Products That Hold Steady
Keep the same person, mascot, or product recognizable across shots and scenes. Seedance 2.5 helps maintain character consistency, keeping facial features, products, and visual identity steady so a lead does not morph between cuts. It works best with clear, high-quality reference images.
Refine One Region, Keep the Rest
Select a specific area and change just that, fix an artifact or swap an element, while keeping the rest of the scene unchanged. Small fixes become a quick edit rather than a full reroll. This is the control brands asked for when one off detail used to cost a whole regeneration.
Audio That Lands in Sync
Generate AI video with native audio, sound effects, and ambience produced alongside the visuals, so the sound stays aligned with the action. Add a voice reference and the model can support synchronized speech. It cuts the separate audio pass you used to need.

Frequently Asked Questions
It is ByteDance's AI video model, built around control. It turns text prompts, images, and references into high-quality video, with native clips up to 30 seconds, up to 50 multimodal references, local region editing, and native synced audio.
2.5 generates up to 30 seconds in one clip where 2.0 tops out around 15 and often needs stitching. It accepts up to 50 references versus 2.0's much smaller cap, and adds local editing so you can fix a region without regenerating the whole video. Use 2.5 for longer, more controlled work; use 2.0 mini to save credits on quick clips.
You guide the result with up to 50 references, such as a product photo, a style image, a video that sets the motion, and an audio track. This multi-reference AI video generation anchors the subject, look, movement, and pacing to your inputs, so the video stays close to your intent. The feature is sometimes called multi-reference creation.
Yes. Seedance 2.5 supports local editing (also called regional editing), which lets you select a specific region and change just that part, like fixing an artifact or swapping an element, without regenerating the whole clip. It turns small fixes into a quick edit rather than a full redo.
Yes. Sound, effects, and ambience are generated alongside the video and stay in sync with the action, so you skip a separate audio pass. Complex voiceover and lip-sync still benefit from a good audio reference.
Add a character or product reference, and Seedance 2.5 helps maintain character consistency across shots and scenes, keeping drift low. It works best with clear, high-quality reference images.
