Seedance 2.5 API

Complete guide to using Seedance 2.5 API: 30-Second Multimodal Video Generation

Seedance 2.5 API: 30-Second Multimodal Video Generation

Seedance 2.5 is available on PoYo for longer, controlled video workflows. Generate 4-30 second videos from text, first and last frames, or multimodal references while maintaining coherent characters, motion, and lighting.

Use up to 30 images, 10 videos, and 10 audio files, with no more than 50 reference files per request. Choose 480p, 720p, or 1080p, control aspect ratio, and optionally generate synchronized audio.

Key Features of Seedance 2.5 API

The currently available API focuses on longer coherent outputs, multimodal references, frame control, and optional synchronized audio.

01

Up to 30 Seconds to Unfold Your Story

Generate a complete 4-30 second output in one request, reducing the stitching work needed for longer ads, stories, training clips, and product scenes.

  • Choose any integer duration from 4 to 30 seconds
  • Generate in 480p, 720p, or 1080p
  • Maintain pacing within one output

02

Up to 50 References to Guide Your Vision

Combine character, product, motion, and sound references in one request, and address them in the prompt as @Image1, @Video1, or @Audio1.

  • Up to 30 reference images
  • Up to 10 reference videos and 10 audio files
  • 50 reference files maximum per request

03

Define the First and Final Frame

Provide one starting frame and an optional ending frame to guide the opening composition and final transition of the generated video.

  • Use one or two image_urls
  • Frame inputs are mutually exclusive with reference media
  • Frame mode uses aspect_ratio=auto

04

Generate Video and Audio Together

Optionally request synchronized audio and choose a supported aspect ratio for the output.

  • Enable or disable synchronized audio
  • Keep video and audio in one asynchronous result
  • Choose from seven supported aspect ratios

Who Can Benefit from Seedance 2.5 API?

01

Brand Ads and Commercial Storytelling

Create longer campaign shots with stable products, characters, lighting, and camera movement. Seedance 2.5 is positioned for polished ad concepts that need more than a short teaser clip.

02

Social Video, UGC, and Short Drama

Generate 30-second vertical scenes for hooks, product demos, scripted UGC, music-driven posts, and short drama beats while keeping the same actor or product consistent.

03

E-Commerce Product Showcases

Use product references, brand assets, and lighting directions to create realistic product motion, hero shots, and lifestyle clips without rebuilding scenes in a traditional studio.

04

Film, TV, and Storyboard Pre-Viz

Turn shot lists and greybox references into longer moving previews, helping directors test pacing, camera language, blocking, and scene continuity before production.

05

Gaming and Virtual Worlds

Prototype cutscenes, character reveals, environment flythroughs, and stylized action sequences using multi-reference guidance for characters, settings, and motion.

06

Enterprise Training and Production Pipelines

Build consistent instructional, onboarding, or internal communication videos where longer scenes, stable presenters, and repeatable brand style matter.

Frequently Asked Questions about Seedance 2.5 API

What is Seedance 2.5?

Seedance 2.5 is ByteDance's AI video generation model for 4-30 second videos from text, first and last frames, or multimodal image, video, and audio references.

Is Seedance 2.5 API available on PoYo now?

Yes. Use model=seedance-2.5 in the playground or the asynchronous generation API.

How do I access Seedance 2.5?

Use the playground on this page or submit model=seedance-2.5 to the PoYo generation API, then poll task status or provide callback_url.

How much does Seedance 2.5 cost?

At 480p it costs 17 credits per billed second with reference video or 28 credits per second without it. At 720p the rates are 38 and 63 credits. At 1080p the rates are 68.5 and 114 credits. With reference video, billed duration equals output duration plus reference-video duration.

How is Seedance 2.5 different from Seedance 2.0?

Seedance 2.5 supports 4-30 second outputs and up to 50 multimodal references, with first/last-frame control and optional synchronized audio.

What duration and resolution does Seedance 2.5 support?

Duration is any integer from 4 to 30 seconds. Output resolution is 480p, 720p, or 1080p.

Can I use images, videos, and audio as references?

Yes. You can provide up to 30 images, 10 videos, and 10 audio files, with no more than 50 reference files in total. Audio requires at least one reference image or video.

How do first and last frames work?

image_urls accepts a starting frame and an optional ending frame. It cannot be combined with reference media, and frame mode uses aspect_ratio=auto.

Can Seedance 2.5 outputs be used commercially?

Commercial use will depend on the final provider terms, PoYo terms, input rights, and regional availability. Avoid uploading copyrighted assets or real-person likenesses without proper permission.
