Blend images, video, and audio into one video with Seedance 2.5 Omni Reference. Selectable 480p–4K output, 30-second clips. Try free — pay per generation, no subscription.
Seedance 2.5 Omni Reference blends multiple reference images, video clips, and audio into a single guided generation, with selectable output resolution (480p/720p/1080p/4K) — price scales with the resolution chosen. Supports clips up to 30 seconds.
About this model
Seedance 2.5 Omni Reference is the early-access multi-reference endpoint in the Seedance 2.5 family, blending up to 30 reference images, 10 video clips, and 10 audio files into a single guided video generation. Use the images to steer environment and style, the videos for camera motion and rhythm, and the audio as a mood reference — all combined via one text prompt. Supports clips up to 30 seconds, with a resolution parameter selecting 480p, 720p (default), 1080p, or 4K output; price scales with the resolution chosen.
Cost analysis
| Provider | Cost | Notes |
|---|---|---|
| muapiapp | $0.17/sec (480p), $0.34/sec (720p), $0.85/sec (1080p), or $1.70/sec (4K) | Rate applies to output duration only when no video reference is used, selectable via the `resolution` parameter on this same endpoint. With a video reference, billed at 65% of that rate on the combined duration of the reference videos plus the generated output. |
| Fal.ai | $0.47/sec (720p) or $0.2205/sec (480p) | MuAPI is ~28% cheaper than Fal.ai at 720p and ~23% cheaper at 480p. |

| Prompt | string | Text prompt describing the desired video, referencing the provided images, video clips, and audio as environment, motion, and mood cues. | Create a calm cinematic park sequence. Use the images for environment style, the video clips for camera motion and street rhythm, and the audio as mood reference. |

| Reference Videos | array | Reference video URLs. Up to 10 clips. | undefined |
| Reference Audio | array | Reference audio URLs. Up to 10 files. | undefined |
| Resolution | Enum (4 options) | Output resolution. Price scales with resolution: 480p is cheapest, 4K is most expensive. | 720p |
| Duration | int | The duration of the generated video in seconds. | 5 |
| Aspect Ratio | Enum (8 options) | Aspect ratio of the output video. | 16:9 |
| Omni Reference Task Type | Enum (4 options) | Hint for the omni-reference subtask type, so ratio/duration constraint mismatches are caught at submission time instead of failing asynchronously. auto lets the model infer the type from the prompt; reference has no special ratio/duration constraints; edit and extend both require ratio=adaptive (edit additionally requires duration=-1). The model still re-derives the actual task type from the prompt during processing, so a mismatch can still surface as an async error. | auto |
| Seed | int | Random seed for reproducible generation. Use -1 for random. | 42 |
| High Bitrate | boolean | Enable high bitrate mode for better visual fidelity. Produces larger files. | false |

It generates video guided by a combination of reference images, video clips, and audio files, blending their style, motion, and mood cues into one output.
Up to 30 images, 10 video clips, and 10 audio files, via `images_list`, `videos_list`, and `audios_list` respectively.
Omni Reference uses the same per-second rate as the base model at each resolution ($0.34/sec at 720p, $0.17/sec at 480p, $0.85/sec at 1080p, $1.70/sec at 4K), but is billed on total video duration — the generated output plus every reference video you supply — not just the output length.
720p by default. Pass a `resolution` value of `480p`, `720p`, `1080p`, or `4k` on the same endpoint to select a different output tier — price scales with the resolution chosen.
Yes — set `resolution` to `1080p` (natively rendered) or `4k` (upscaled from a 720p base render) on this same endpoint. Both are priced above the 720p tier.
Between 4 and 30 seconds, configurable via the `duration` parameter.
No — provide any combination of images, videos, and audio. A text prompt alone still works, but references help steer style, motion, and mood more precisely.
