Overview
Seedance 2.5 is ByteDance's audio-video generation model designed for longer storytelling, reference-guided creation and professional video production. It can generate videos up to 30 seconds in a single generation and can be extended further for longer sequences.
The model combines visual and audio generation rather than treating them as completely separate stages. This makes it suitable for scenes that require coordinated movement, dialogue, sound and cinematic presentation.
One of Seedance 2.5's important capabilities is reference control. Users can provide reference videos and other visual inputs to guide the generated result. ByteDance describes the model as being able to understand the intention, framing and cinematic language of reference videos rather than simply copying their movement.
The model also provides editing capabilities for audio and visual content. Professional production features include green-screen editing, camera movement and performance blocking, making it relevant to more structured video workflows.
Seedance 2.5 is available through different platforms and APIs. Runway's developer platform currently lists support for Seedance 2.5 at 480p, 720p and 1080p, with generations up to 30 seconds and pricing starting at $0.20 per second.
The combination of longer clips, multiple references and audio-video generation makes Seedance 2.5 useful for storytelling, advertising, product videos, social content and other workflows where creators need more than a short isolated AI clip.
How Seedance 2.5 works
In practice, Seedance 2.5 works best when you give it references. Supplying a reference video or images tells the model about framing, pacing and style, so the generated result follows your direction instead of improvising.
Since it can produce up to 30 seconds with audio, you can plan a complete beat, such as a product reveal with a line of dialogue, in one pass and then extend it when the story needs more time.
Getting started with Seedance 2.5
- Choose a platform that offers Seedance 2.5, such as ByteDance's own products or a developer platform listing it.
- Prepare references: images for character and setting, and optionally a reference video for camera style.
- Write a prompt covering action, camera and the sound you expect.
- Generate at 480p for testing, then re-run the best idea at 1080p.

What does Seedance 2.5 cost for longer videos?
