# Seedance 2.5 - AI video generation with audio
> Generate 30-second videos with synchronized audio, multimodal reference control, and precise editing using Seedance 2.5 in ComfyUI
Seedance 2.5 is ByteDance's new-generation video creation model, launched on July 31, 2026. Building on the unified multimodal audio-video joint-generation architecture of Seedance 2.0, it shifts the focus from generating a single clip to completing a full creative work, with major breakthroughs in long-form storytelling, multimodal reference, and editing.
The model generates up to 30 seconds of high-quality audio-video in a single pass, with improved shot transitions and scene changes for stronger continuity in longer videos. It supports multiple rounds of extension, so creators can build multi-minute content with a consistent audiovisual language, bringing a complete story to life in one take. Image, audio, and motion quality are all improved over the previous generation, resulting in more natural, polished visuals.
## What Seedance 2.5 is good at
* **30-second generation**: Produces high-quality, 30-second audio-video clips in a single pass with multi-round extension
* **Audio-video sync**: Generates video and audio together, including dialogue and lip-synced speech
* **Fully upgraded multimodal referencing**: Accepts up to 30 reference images, 10 video clips, and 10 audio clips for character consistency, visual style, and motion rhythm control
* **Precise editing**: Offers timestamp-level control for targeted edits of video and audio, plus green screen and reference-based editing
* **Multi-round extension**: Extends clips to build multi-minute content with consistent audiovisual language
* **Versatile use cases**: Suited for brand films, episodic series, e-commerce content, product showcases, and character-driven short series
