Input

Prompt(string)

The text prompt to generate a video from.

Duration

Output duration in seconds (4-30), or `auto` to let the model pick a length from the prompt and inputs. `auto` is pre-authorized at 30 seconds and billed on the actual output length. Allowed values: auto, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30.

Aspect Ratio(string)

Output aspect ratio. Defaults to 16:9. Allowed values: 16:9, 9:16, 1:1, 4:3, 3:4, 21:9.

Resolution(string)

The resolution of the video to generate. Allowed values: 480p, 720p, 1080p.

Generate Audio(boolean)

Whether to generate synchronized audio (voice, SFX, BGM) for the video.

Seed(integer)

Random seed for reproducible results. Omit or use -1 for a random seed. Range: -1 to 4294967295.

Draft Mode (480p)(boolean)

Draft mode step 1: render a fast, low-cost 480p draft (overrides `resolution`, billed at the 480p rate). Pass the result's `outputs[0].draft_id` back as `draft_id` within 7 days to render the same shot at 1080p.

Draft ID(string)

Draft mode step 2: the `outputs[0].draft_id` of a succeeded draft from this same model (created with `draft: true` in the last 7 days). Renders the same shot at 1080p, billed at the 1080p rate for the actual output length. The prompt, media, duration, aspect ratio, seed, audio setting and task type are reused from the draft; any such fields sent with `draft_id` are ignored.

API README

Seedance 2.5 Text to Video

Seedance 2.5 text-to-video, ByteDance's newest video model: coherent single-shot clips up to 30 seconds with native audio and director-level camera control. Write the scene, including dialogue and sound, and get back a 4–30 second clip.

Fields

Field	Type	Default	Notes
`prompt`	string, required	—	Up to 50,000 characters.
`duration`	`auto` / 4 / 5 / 6 / 7 / 8 / 9 / 10 / 11 / 12 / 13 / 14 / 15 / 16 / 17 / 18 / 19 / 20 / 21 / 22 / 23 / 24 / 25 / 26 / 27 / 28 / 29 / 30	5	Output length in seconds (4–30), or `auto` to let the model choose.
`aspect_ratio`	`16:9` / `9:16` / `1:1` / `4:3` / `3:4` / `21:9`	`16:9`	Output frame shape.
`resolution`	`480p` / `720p` / `1080p`	`720p`	Sets the per-second rate.
`generate_audio`	boolean	true	Native dialogue, music, and effects. Same price on or off.
`seed`	integer -1–4294967295	random	Fix it to compare prompt changes; `-1` is random.

Billing

You pay for output seconds: $0.18 at 480p, $0.36 at 720p, $0.90 at 1080p. Audio is included. With duration: "auto" the quote assumes 30 seconds and the final charge uses the generated length.

Output	480p	720p	1080p
4s	$0.72	$1.44	$3.60
5s (default)	$0.90	$1.80	$4.50
10s	$1.80	$3.60	$9.00
15s	$2.70	$5.40	$13.50
30s	$5.40	$10.80	$27.00

Failed runs are not charged.

Prompting

Describe subject, action, camera move, and light in order; add the sound last.
Quote dialogue and name the speaker.
For several shots, number them and give each a camera direction.

Limits

Clips are 4–30 seconds.

Draft mode

Draft mode is two calls to this same model:

Draft: add "draft": true. The output is a 480p preview billed at the 480p rate, and outputs[0].draft_id identifies it.
Final: send {"draft_id": "<outputs[0].draft_id>"} (optionally watermark). The same shot is rendered at 1080p and billed at the 1080p output rate for the actual output length.

The final reuses the draft's prompt, media, duration, aspect ratio, seed and audio setting; those fields are ignored when draft_id is set. A draft can be finalized within 7 days, only with the model that created it.

{"prompt": "A red toy sailboat drifts slowly from left to right across calm blue water. Fixed camera.", "duration": 4, "aspect_ratio": "16:9", "generate_audio": false, "draft": true}

{"draft_id": "<outputs[0].draft_id from the draft>"}
