Overview

About this model

Updated Jul 16, 2026

Seedance 2 Omni Reference (Fast) delivers the same multi-modal reference capability as the standard Omni Reference model—combining up to 9 image references and 3 audio files—but at reduced cost and faster processing speed. Use it for rapid iteration, client approvals, and production pipelines where speed matters more than maximum visual polish. Reference images are labeled @image1, @image2, etc., and audio as @audio1, @audio2, etc., in your prompt.

Ideal for high-volume content creators, advertising agencies, and production teams that need quick turnarounds on reference-heavy videos. At just $0.75 per generation, this fast variant makes multi-element video production cost-effective for iterative workflows and tight deadlines.

Technical Details

Configuration schema

Promptstring

Video description. Use @image1…@image9 to reference images and @audio1…@audio3 for audio. To use a character sheet, reference it with @character:<request_id> (from a completed Seedance 2 Character generation). To use a trained Omni Reference character, reference it with @omni-character:<character_id> where character_id is the value returned by Omni Reference Train Character (e.g. char_1775422630065_4vbana). Both methods can be combined in the same prompt. Multiple characters are supported. Example: '@omni-character:char_1775422630065_4vbana walking through a neon-lit city at night'.

Default Value@image1 is the main character. The person walks along a city street at sunset, cinematic lighting.

Implementation Guide

Developer documentation

  1. Prepare up to 9 image references and upload each to a publicly accessible URL; create a list of these URLs. 2. Prepare up to 3 audio files and upload each to a public URL; create a list of audio URLs. 3. Write your prompt, referencing images as @image1, @image2, etc. and audio as @audio1, @audio2, etc., indicating how each should be used (e.g., '@image1 shows the product against @image2 lifestyle backdrop, with @audio1 brand music driving the pacing'). 4. Select your aspect_ratio and duration. 5. Submit—the fast variant generates video coordinating all references with quick turnaround.
