Seedance 2.5 is ByteDance's latest AI video generation model, built to create native 4K cinematic videos up to 30 seconds long from text prompts, images, audio, video clips, and multimodal references. Available through Seedance25AI, it delivers longer single-pass generation, stronger character consistency, and more controllable editing, making it suitable for professional video production, advertising, and creative storytelling.

Compared with earlier versions, Seedance 2.5 focuses on producing longer, more coherent videos while reducing the need for stitching multiple clips together during post-production.

How does Seedance 2.5 work?
Seedance 2.5 is powered by a multimodal AI video generation architecture that understands text, images, audio, video, and multiple reference assets within a single workflow. This enables creators to generate, edit, and refine videos while maintaining visual consistency across scenes.

Key features include:
30-Second Native Video Generation: Create complete videos in a single generation without stitching.
Text-to-Video & Image-to-Video: Generate cinematic videos from prompts or reference images.
Up to 50 Multimodal References: Combine text, images, audio, and video files to guide video generation.
Native 4K Output: Produce professional-quality 4K videos with richer color and detail.
Character & Scene Consistency: Keep characters, clothing, lighting, and environments consistent throughout long sequences.
Local Video Editing: Modify specific subjects or regions without regenerating the entire clip.
Multilingual Generation: Supports multiple languages while reducing unwanted subtitles and background audio.

Users simply write a prompt, upload optional reference assets, select the desired resolution and aspect ratio, and generate production-ready AI videos directly in the browser.
