Seedance 2.5 is ByteDance’s next-generation Doubao video model, built to push past the limits of Seedance 2.0. It generates native 30-second single-segment clips, understands up to 50 multimodal references at once, and supports localized edits that keep an approved shot’s motion and lighting intact.

Seedance 2.5 AI Video Generator
Generate a native 30-second take from prompts, images, and reference clips - then refine it without starting over.
Flagship capability
A full 30-second take, generated in one pass
Seedance 2.5 renders a native 30-second single-segment clip instead of a handful of short shots you have to stitch. Spatio-temporal attention runs across the whole take, so faces, wardrobe, lighting, and physics hold from the first frame to the last.
- Native 30s single-segment video, with high-quality extension
- Up to 50 multimodal references understood together
- Localized edits that keep the original camera move and lighting

Built for Longer, Controllable AI Video
Native length, multimodal direction, and edit-friendly outputs — so you spend less time stitching and more time directing
Native 30-Second Clips
Generate a full 30-second single-segment video in one pass, then extend when the story needs more room — without resetting character look between cuts.
Up to 50 Multimodal References
Bring images, video, audio, and even 3D assets into one generation. Seedance 2.5 reads them together so cast, style, and environment stay aligned.
Localized Video Editing
Swap a subject, backdrop, or product while preserving camera move, motion, and lighting — iterate on an approved shot instead of starting over.
Full-Clip Consistency
Spatio-temporal attention across the whole clip keeps faces, wardrobe, lighting, and physics stable from the first frame to the last.
Sharper Prompt Control
Complex camera language, blocking, transitions, and multi-character beats land closer to what you wrote — with roughly 20% stronger prompt adherence vs Seedance 2.0.
Seedream 5.0 Pro Pipeline
Generate precise stills in Seedream 5.0 Pro, then animate them with Seedance 2.5 for a coherent image-to-video workflow in the same SparkVid workspace.

Where Seedance 2.5 Shines
Longer clips, denser references, and editable shots for teams that ship video every week
Ensemble & Short-Drama Scenes
Load cast and environment references, then direct blocking and camera with prompts — keep multiple characters consistent across the beat.
Film Pre-Visualization
Feed whitebox 3D and material refs to explore motion and staging before a live shoot — structure stays readable even in dynamic action.
Ad & E-Commerce Localization
Reuse a hero take across markets by swapping products or talent while keeping the original camera and polish.
Explainers & Education
Build precise stills with Seedream 5.0 Pro, then turn them into clear motion sequences without a full production crew.
Story-Driven Social Clips
A native 30-second take is long enough for setup, turn, and payoff — ideal for brand stories and short-form episodes.
Image-to-Video Pipelines
Animate storyboards and concept art in one generation. Dense reference input lets an entire board drive a single coherent clip.
Frequently Asked Questions
Quick answers about Seedance 2.5 on SparkVid
Three big upgrades: native clips jump from a few seconds to a full 30-second take in one pass, the reference budget grows to 50 full-modal assets including 3D, and you can now make localized edits — swap a subject or backdrop — without regenerating the whole shot. Prompt adherence on complex, multi-beat scenes is also roughly 20% stronger.
Seedance 2.5 generates native 30-second single-segment videos in one pass — about double what most models manage — and supports high-quality extension when a story needs more room. Because the whole take renders together, characters, lighting, and physics stay consistent from the first frame to the last.
Up to 50 assets per generation, spanning images, video clips, audio, style boards, and even 3D models. Seedance 2.5 reads them jointly rather than one at a time, so you can lock in cast, wardrobe, and environment with real references instead of describing everything in a prompt.
Yes. Seedance 2.5 is live on SparkVid — the generator on this page runs on it. Pick Seedance 2.5 in the model list to generate clips of up to 30 seconds at 480p, 720p, or 1080p, with native audio and reference images, videos, and audio.
Yes. Videos created on a paid SparkVid plan can be used in ads, client work, social content, and other commercial projects under our standard terms — check the pricing and terms pages for the current details.
Yes — that’s one of its biggest upgrades. Localized editing lets you swap a subject, background, or product while the camera move, motion, and lighting from the original take stay exactly as they were, so you can refine an approved shot instead of starting over from scratch.
Seedance 2.5 is built for high-fidelity output up to 4K. On SparkVid you can generate in the aspect ratios you actually need — 16:9, 9:16, and 1:1 — so a single clip is ready for YouTube, TikTok/Reels, and cinematic delivery alike.
