Input

Prompt

"Beneath the Walls of Troy" - an epic action short. @Image1 is a Greek hero in golden armour and a crimson cloak with a long spear and a lion shield; @Image2 is a Trojan champion in black armour and a blue cloak with a curved sword and a horse shield; the setting follows the walls of Troy and the sunset battlefield of @Image3. Keep each warrior's armour, helmet, cloak colour and shield emblem exactly as in their own reference - never swap them.
Opening: wind drives the sand as the two face off twenty paces apart, sharp eyes behind their helmets.
Middle: they charge at once; the spear strikes the horse shield in a burst of sparks; rapid slashes and blocks up close as the camera orbits them 360 degrees.
Climax: the setting sun sits right between them as they clash mid-air in extreme slow motion, sparks, sand and the crimson cloak hanging in the air.
Ending: both lower their weapons and salute each other.
Cinematic action-commercial look, 24fps film grain, fluid and weighty fighting; war drums, clashing metal and an epic score with the big hits on the beat. No blood or wounds, no extra characters, no on-screen text or watermarks, no deformed weapons or limbs.

With multiple references, address them in the prompt as @Image1 / @Image2, e.g. "the character from @Image1 stands in the scene from @Image2". Without tokens the model decides on its own.

Real human faces work as reference images, no masking needed. Please make sure you have the right to use the likeness of anyone pictured.

Reference videos0 / 3

Click to upload or drag files here mp4 / mov, up to 50 MB and 30 s each; all reference videos together at most 15s or paste links

Can be combined with reference images: photos set the look, the video sets motion and camera. Address it as @Video1 in the prompt.

Reference audio0 / 3

Click to upload or drag files here mp3 / wav / m4a, up to 15 MB and 30 s each or paste links

Needs a reference image or video as well. Address it as @Audio1 in the prompt.

Uploaded references are kept for 7 days.

Rendering usually takes 5-20 min; when the backend is busy it can exceed 60 min (no result after 120 min counts as a timeout, fully refunded). Poll the job id rather than resubmitting - each resubmission is billed separately. Billed per second, fully refunded on failure. Prompt limit 5000 bytes (about 1666 Chinese characters).

Content requirements

Full details →

Everything is reviewed
The prompt, the reference files and the finished clip all go through content review, picture and sound alike.
No charge if rejected
A rejected job is not charged; the credits held at submit are refunded in full.
The finished clip is reviewed again
Some jobs are rejected at submit; others only when the finished clip is reviewed, anywhere from a few minutes to over half an hour later.
Sound is reviewed too
Spoken lines, narration and lyrics in your prompt are voiced or sung, and reviewed together with the picture. If you need no voices, leave out lines and lyrics. This model always adds a soundtrack; it cannot be turned off. Uploaded reference audio is reviewed as well.
Commonly rejected
Sexual content or nudity; gore, self-harm and violent injury such as gunshot wounds; firearms, explosives and drugs; minors shown with alcohol, tobacco or in danger; politicians, celebrities and other public figures, in looks or voice (look-alikes included); copyrighted characters.
One bad shot fails the whole clip
If a single shot in a long storyboard script breaks the rules, the whole clip is rejected. Resubmitting the same input is rejected again; fix that part or replace the reference, then retry.

About Seedance 2.0

Seedance 2.0 is the standard tier of ByteDance's Seedance 2.0 family. Duration is any integer 5-15 seconds, three resolutions (480P / 720P / 1080P), five aspect ratios (16:9 / 9:16 / 1:1 / 4:3 / 3:4), with an optional generated soundtrack; omit the reference image for text-to-video, include reference images for image-to-video (they set the subject, scene and style; they are not used as the first frame). Async job: POST /v1/videos/generations returns HTTP 202 and a job id immediately; poll GET /v1/videos/jobs/{id} until status=succeeded and read data[0].url. That link is an mp4 re-hosted by us — it is kept for 15 days (far longer than the upstream CDN link), so download it or copy it to your own storage before then.

Use cases

Standard short-form production

5-15 seconds covers most social and ad asset lengths.

Image-to-video

Reference images pin down the subject, wardrobe and scene, so product shots and character sheets come alive; name them @Image1 / @Image2 in the prompt and the identity carries through.

Multi-ratio delivery

Run the same prompt at 16:9 / 9:16 / 1:1 to reuse one idea across platforms.

Clips with sound

audio is on by default, so clips ship with ambient sound and skip a separate audio pass.

How to choose

Pick it when visual quality comes first or you need 1080P — 2.0 is the standard tier of Seedance 2.0 and the only one in the family with 1080P. When budget comes first use seedance-2.0-fast (the low-latency tier: same lengths and ratios, lower rate); for bulk drafts use seedance-2.0-mini; for more than 15 seconds use seedance-2.5.

FAQ

Which resolution should I pick?

480P, 720P and 1080P are selected with the resolution parameter; 720P is the default and each tier has its own per-second rate (see the price box; 480P is 20% under 720P). A tier that is not open yet is refused at submit with a clear message — never silently downgraded, never charged.

How is it different from 2.0 Fast?

2.0 is the standard tier; Fast is the low-latency tier of the same generation — same lengths, ratios and reference limits, no 1080P, lower rate. Choose 2.0 for fine detail and stability, Fast when cost matters.

How does image-to-video work?

Pass images (an array of reference images; a single one can go in image), as public URLs, data: URIs or base64. They reach the model as references for the characters, objects, scene or style, and you address them in order as @Image1, @Image2 in the prompt; the model has no first/last-frame control, so a reference image is not guaranteed to be the opening frame. The same request can also carry reference videos in video_references (@Video1, for motion and camera) and reference audio in audio_reference (@Audio1).

How is it billed, and am I charged on failure?

Billed per second (reference-video seconds count too): the hold placed at submit is computed from the duration you asked for, and the settle is the exact same number. A failed or timed-out render refunds the whole hold, so you never pay for a clip you did not receive.
