Overview

About this model

SD 2.0 Omni Reference 480p generates videos with visual consistency using reference images, videos, and audio at 480p resolution. It offers the same multi-modal reference capabilities as the 720p variant — maintaining character identity, visual style, and scene continuity — at a lower cost. Combine up to 9 images, 3 video clips, and 3 audio files in a single request. Use @image1, @video1, @audio1 syntax in your prompt to precisely control how each reference influences the generated video.

1Character Consistency: Keep a character's appearance consistent across multiple scenes by providing a portrait as @image1.
2Style Transfer: Apply the visual style of a reference image to a newly generated video scene.
3Audio-Synced Video: Generate video synchronized to a reference music clip or voice recording via @audio1.
4Scene Continuity: Provide a scene screenshot and generate a visually matching continuation.
5Draft Previews: Quickly prototype multi-modal video concepts at 480p before committing to 720p generation.

To use a fictional character, reference it with @character:<id> (request_id from a completed Seedance 2 Character generation) — characters are automatically appended to images_list. Multiple characters are supported.

Common Questions

Frequently asked

How is this different from the 720p Omni Reference?

This endpoint generates 480p video, which is faster and more cost-effective ($0.18/sec basic, $0.24/sec high output) compared to the 720p variant ($0.21/sec basic, $0.30/sec high output). Both variants apply a 30% surcharge on the per-second rate for each second of input video provided. The minimum duration is 8 seconds and aspect ratio options are limited to 16:9, 9:16, 4:3, and 3:4.

How do I reference my uploaded files in the prompt?

Use @image1, @image2, etc. to reference images by position in images_list. Use @video1, @video2 for videos by position in video_files. Use @audio1, @audio2 for audio files by position in audio_files.

Do I need to provide all types of references?

No. All reference arrays are optional. You can provide just images, just a video, just audio, or any combination. A text-only prompt is also valid.

What file formats are supported?

Images: JPEG, PNG, or WebP (up to 9). Videos: MP4 only, max 15 seconds each (up to 3). Audio: MP3, WAV, or other common formats, total max 15 seconds (up to 3 files).

How is cost calculated?

Cost = (rate × output_duration) + (0.3 × rate × total_input_video_duration). 'high' quality: $0.24/sec output. 'basic' quality: $0.18/sec output. If video_files are provided, a 30% surcharge applies per second of combined input video duration. Example: 8s output (basic) + two 5s input videos = 8×$0.18 + 10×$0.054 = $1.44 + $0.54 = $1.98.

Why is the minimum duration 8 seconds?

The 480p Omni Reference variant requires at least 8 seconds of output to properly incorporate multi-modal references.
