Seedance 2.5

Professional AI Video Generation for Creators and Brands

Seedance 2.5 is ByteDance's next-generation multimodal AI video generator that produces native 30-second 4K videos in a single run. Built by the Doubao team, it eliminates the need for manual clip stitching and extensive post-production by generating continuous, high-fidelity video sequences directly from your creative assets.

Multimodal Reference System

Unlike traditional text-to-video tools, Seedance 2.5 supports up to 50 reference inputs per project:

• 30 reference images (up to 4K resolution, 30MB each) to lock in visual style, character appearance, and scene composition • 10 reference videos (totaling up to 30 seconds) to define motion patterns, camera movements, and pacing • 10 reference audio files (totaling up to 30 seconds) to drive video rhythm, coordinate physical actions, and enable automatic lip-sync

This unified approach lets you combine storyboards, product shots, voice clips, and background music into a single generation workflow, maintaining consistency across characters, lighting, environments, and visual styles throughout the entire 30-second output.

Key Capabilities and Workflow

Seedance 2.5 delivers production-ready features designed for content creators, marketing teams, ecommerce brands, and enterprise users:

• Native 30-second generation – No stitching required; smooth storytelling with emotional depth and consistent scenes • 4K resolution output – Professional-grade visual quality suitable for high-end ad campaigns and brand films • Precise local video editing – Modify specific areas like products, characters, or green screens while preserving surrounding lighting and scene stability • Multilingual prompt support – Write complex directions natively in over 10 languages including Spanish, Arabic, Japanese, English, Chinese, and Korean • Character and scene consistency – Maintains character features, clothing, environments, and visual styles across multi-scene sequences

Who It's For

Seedance 2.5 empowers diverse users across industries:

• Social media creators generating TikTok, Instagram Reels, and YouTube Shorts with consistent styling and music visuals • Marketing and ad teams building product ads, campaign hooks, and promotional videos from reference images without full production shoots • Ecommerce and product brands transforming product features into clear demos and motion concepts for testing before committing to physical shoots • Enterprise teams creating onboarding materials, product education, internal training, and corporate explainers from rough sketches or existing footage

What Sets It Apart

Seedance 2.5 represents a major upgrade over Seedance 2.0, doubling maximum duration from 15 to 30 seconds and expanding reference capacity from 12 to 50 mixed assets. The model delivers sharper 4K-ready visual quality, stronger multi-asset control, better audio-aware timing, more natural lip-sync for dialogue performance, and precise regional editing capabilities that let you fix individual details without regenerating entire clips—saving time and generation credits.
