# Seedance

> ByteDance's video models: Seedance 2.5 for references, editing and extending, and the lower-cost Seedance 2.0 tiers.

Seedance, from ByteDance, makes video from text, frames or references, with
sound. Seedance 2.5 is the most capable. The Seedance 2.0 models are older and
cost less.

| Model | Best for | Resolutions | Duration |
| - | - | - | - |
| **Seedance 2.5** | Many references, editing and extending video, drafts | 480p Draft, 480p, 720p, 1080p | 4–30 seconds |
| **Seedance 2.0** | 4K output | 480p, 720p, 1080p, 4K | 4–15 seconds |
| **Seedance 2.0 Fast** | Faster, lower-cost clips | 480p, 720p | 4–15 seconds |
| **Seedance 2.0 Mini** | The lowest cost | 480p, 720p | 4–15 seconds |

## What you can give it

* **A prompt** on its own.
* **Frames**: a start frame, and an optional end frame. Frames can't be
  combined with references.
* **References**: images, videos and MP3 audio.
  * Seedance 2.5 takes up to 50: 30 images, 10 videos and 10 audio clips.
    Videos and audio can each run 2 to 30 seconds, 30 seconds in all.
  * Seedance 2.0 models take up to 10: 9 images, 3 videos and 3 audio clips,
    with up to 15 seconds of video. Audio needs an image or video beside it.

With references, **Video mode** chooses what Seedance does with them:
**Reference media**, **Edit video** or **Extend video**. Edit and extend need a
reference video. See [Make a video](https://docs.zerogen.com/generate/make-a-video.md).

Seedance refuses a recognizable person in a reference that isn't marked as a
real person. See
[Mark a real person](https://docs.zerogen.com/generate/frames-and-references.md#mark-a-real-person).

## Output settings

| Setting | Options |
| - | - |
| Aspect ratio | 16:9, 4:3, 1:1, 3:4, 9:16, 21:9. Seedance 2.5 adds **Auto**, and uses it with frames, editing and extending. |
| Audio | On or off. Sound doesn't change the price. |
| Output format | Seedance 2.5 only: **MOV · YUV 4:4:4**, the default, or **MP4**. |
| Quantity | 1 to 4 videos. |

## Draft, then upscale

Seedance 2.5 starts at **480p Draft**, a low-cost preview. Upscale a draft you
like to 1080p within 7 days. See [Draft, then upscale](https://docs.zerogen.com/generate/draft-then-upscale.md).

## Cost

Seedance is priced by the video it makes: longer, bigger and higher-resolution
videos cost more, and input video adds to the price. A 5-second video costs
about:

| Model | Estimate |
| - | - |
| Seedance 2.5, 480p Draft | About \$0.71 |
| Seedance 2.0, 720p | About \$1.00 |
| Seedance 2.0 Fast, 720p | About \$0.80 |
| Seedance 2.0 Mini, 720p | About \$0.50 |

Prices are as of October 28, 2026.
