Seedance 2.5 Model Parameters
Check the parameters that affect the prompt before generation: duration, reference inputs, editing scope, audio references, and best-fit outputs.
Online access01
SeedVideo AI provides an available video generation entry point.
Prepare the Seedance 2.5 prompt, reference roles, and 30-second structure before opening the generation flow.
Model type02
Multimodal AI video generation and editing model.
Seedance 2.5 combines text, images, video, audio, and localized editing in one reference-led workflow.
Maximum duration03
Up to 30 seconds.
This is the key planning point for complete ads, avatar explainers, tutorials, and cinematic clips.
Output quality04
480p or 720p in MP4 or MOV format.
The default output is 720p MP4. Supported aspect ratios include 16:9, 9:16, 1:1, 4:3, 3:4, 21:9, and adaptive.
Reference capacity05
Up to 30 images, 10 videos, and 10 audio files.
Use the larger reference budget to separate identity, product, environment, motion, rhythm, and style inputs.
Reference inputs06
A text prompt plus image, video, and audio references.
Assign each input a job so the model knows what should guide the subject, scene, movement, and timing.
Localized editing07
More controllable localized edits.
Name the exact region to change, then lock the subject, background, camera, and timing details that should stay fixed.
Audio references08
Use audio references for rhythm, music direction, sound cues, and dialogue pacing.
Pair audio notes with visual references so the clip has a clearer timing plan before generation.
Output plan09
A complete 30-second AI video sequence.
Plan the hook, subject motion, proof moment, and final frame before you generate the first version.
Format planning10
Decide horizontal, vertical, or square framing before generation.
Lock the target channel early so the prompt, camera path, subject scale, and final frame do not fight the crop.
Best-fit outputs11
Product ads, AI UGC, AI avatar planning, ecommerce content, cinematic scenes, and viral social clips.
These are the strongest fits for a longer, reference-led Seedance 2.5 workflow.

| Image to video | Use product, character, style, and environment images as dedicated reference assets. | Varies by product surface and selected generation workflow. | Strong fit when one image needs expressive motion, action, or social-video movement. | Useful for image-led generation and post-production-style creative edits. |
| Video reference | Use motion clips as reference assets for camera movement, action, pacing, and shot structure. | Varies by product surface. | Varies by product surface and workflow. | Strong fit when existing footage is the starting point for an edit or extension. |
| Audio reference | Use audio to guide rhythm, music direction, sound cues, and dialogue pacing alongside visuals. | Varies by product surface. | Varies by product surface. | Varies by tool and editing workflow. |
| Max duration planning | Up to 30 seconds for a hook, subject motion, proof moment, and final hold. | Varies by product surface and release. | Varies by product surface and release. | Varies by tool, plan, and editing workflow. |
| Long-scene continuity | Strong fit for longer reference-led scenes where identity, product, camera, and rhythm need to stay aligned. | Strong fit for realistic cinematic scenes and physical motion. | Strong fit for image-led motion, character action, and short social clips. | Strong fit when continuity depends on editing or extending existing footage. |
| Multimodal control | A text prompt plus up to 30 images, 10 videos, and 10 audio files for a more controlled generation plan. | Varies by product surface. | Often strongest when image or video references lead the prompt. | Editing-first controls for footage, masks, scene changes, and iterative revisions. |
| Best fit | Product ads, AI UGC, AI avatar planning, ecommerce content, cinematic scenes, and longer reference-led workflows. | Cinematic realism, physics-heavy scenes, lighting, and large-scale visual quality. | Image-to-video motion, character action, expressions, and social video ideas. | Editing existing footage, replacing details, relighting, cleanup, and versioning. |

Source on YouTube“For the 2.5 clips the thing that mattered most was keeping the state changes low, cram more than about 4 distinct actions into a 15s prompt and the middle ones just vanish. I also put the expensive 'lock this exact character/product' line at the very end of the prompt so it doesn't get diluted.”

Frequently Asked Questions About Seedance 2.5
Seedance 2.5 is ByteDance's multimodal AI video model for turning prompts and references into longer, more controlled clips. On Seedvideo, use it to plan and generate from text prompts, images, video clips, and audio references.
Yes. Seedance 2.5 can use audio direction alongside visual prompting so speech rhythm, sound cues, music timing, and motion can be planned together before export.
Seedance 2.5 is built around videos up to 30 seconds, which gives enough room for product ads, avatar explainers, tutorials, social clips, and short multi-shot stories.
Yes. Describe the shot order, camera movement, pacing, and scene progression in the prompt so the model can organize a multi-shot sequence instead of one static moment.
Yes. Write each character role, appearance, dialogue beat, and reaction clearly, then keep those details stable across the prompt and references so interactions remain easier to follow.
Start with a text prompt. Add one or two images for frame-based generation, or use reference mode with up to 30 images, 10 videos, and 10 audio files.
Write the prompt like a short storyboard: opening shot, subject action, camera path, transition, mood, key beat, and final frame. Clear transitions usually work better than a generic request for a cinematic look.
Use stable names, clothing cues, facial details, product details, color palette, and role descriptions. When revising, change only the part that drifted instead of rewriting the entire scene.
Paid campaigns and client projects depend on the active Seedvideo plan, export rules, and the rights attached to your prompts, references, likenesses, and brand assets. Review those rules before publishing.
Generation time depends on clip length, prompt complexity, reference count, audio direction, and current platform load. Shorter briefs with fewer moving parts are usually easier to preview and refine.
Seedance 2.5 is available on Seedvideo. Generation uses account credits, and any free trial allowance depends on the active account plan.
Seedance 2.5 focuses on longer 30-second planning, larger multimodal reference sets, stronger continuity, and more controlled editing direction compared with the shorter Seedance 2.0 workflow.
Yes. A 30-second structure can cover the hook, product close-up, lifestyle scene, benefit proof, and closing CTA in one more complete ad sequence.
Seedance 2.5 is designed for cleaner detail and stronger visual continuity, but the final export quality still depends on the selected settings, source assets, and platform support.
Face and likeness references should follow the latest Seedvideo policy and your asset rights. For production work, use approved characters, licensed material, or consented references.
It describes a model design that processes visual and audio signals in coordinated branches, helping motion, timing, and multimodal references stay better aligned.
Yes. Describe the subject, action, scene, style, lighting, camera movement, pacing, and final frame to generate from text.
Yes. Upload image references to guide characters, products, composition, style, and scene consistency before generating motion.
