Model Input

Input

Describe the scene, the action, the camera move, and the sound you want. English, Chinese, Japanese, Indonesian, Spanish and Portuguese prompts are all understood.

Output resolution of the clip. Higher resolutions cost more per second of video.

Frame shape of the clip. Use adaptive to let the model pick the framing.

Min: 4 - Max: 15

Clip length in seconds.

Additional Settings

Customize your input with more control.

Generate a synchronized soundtrack (dialogue, ambience and sound effects) together with the picture. Set false for a silent clip; the price is the same either way.

Model Details

Model Details

Seedance 2.0 Mini is the cheapest way into the Seedance 2.0 video family: a written prompt becomes a short clip with a synchronized soundtrack, so dialogue, ambience, and sound effects are generated together with the picture rather than dubbed on afterwards. Clips run 4 to 15 seconds at 24 fps, at 480p or 720p, in seven frame shapes from 21:9 cinematic to vertical, with prompts understood in English, Chinese, Japanese, Indonesian, Spanish, and Portuguese. It costs about half the flagship tier per second and returns a clip faster — the tier for drafting, storyboarding, and high-volume work.

One price note: Mini's 720p rate sits just above the flagship tier's 480p rate — choose between them on resolution and fidelity, not price. Mini buys 720p at Mini quality; the flagship's 480p buys less resolution at flagship quality.

## Best for - Cheap, high-volume clip generation where cost matters more than fidelity - Drafting and storyboarding shots before committing to a higher tier - Social posts, ad variants, and quick b-roll that still need sound - Trying many prompt variants of one scene in a single sitting

## Choose another model when - You need 1080p, or the family's best motion and prompt adherence — use `bytedance/seedance-v2/text-to-video` - You want a middle tier — better than Mini, still 720p, cheaper than the flagship — use `bytedance/seedance-v2-fast/text-to-video` - You want to animate a photo you already have — use `bytedance/seedance-v2-mini/image-to-video`, which takes your still as the first frame - You need reference-image consistency, pinned first/last frames, or footage restyled — flagship tier only: `bytedance/seedance-v2/reference-to-video`, `bytedance/seedance-v2/first-last-frame`, `bytedance/seedance-v2/video-to-video`

## Tips - Describe the sound as explicitly as the picture ("gulls calling, waves on shingle") — the audio track follows the prompt - Set `generate_audio` to false for a silent clip; the price is unchanged either way - Draft at `480p`, then re-run the keeper at `720p` — resolution is the largest cost driver and duration the second

## Limitations - As the smallest tier, fidelity and prompt adherence sit below the Fast and flagship tiers — the trade for the price - 720p is the ceiling here, and fast motion or crowds smear at 480p - No seed and no camera lock: runs are not reproducible, and camera moves go in the prompt - Long multi-shot prompts drift in character, wardrobe, and lighting; in-frame text is frequently misspelled

To run via the ModelRunner JavaScript client: ```js import { modelrunner } from "@modelrunner/client";

const result = await modelrunner.subscribe("bytedance/seedance-v2-mini/text-to-video", { input: { prompt: "A market stall at first light, steam rising from a tea urn, the vendor stacking crates as a tram rattles past, city hum and clinking glass", resolution: "720p", aspect_ratio: "9:16", duration: 6, generate_audio: true, }, }); ```
