doubao-seedance-2-0-260128 is ByteDance Seedance 2.0 Standard Edition, suitable for combining text, character images, and audio-video references into short videos. It can bring static images to life while using reference materials to constrain subjects, actions, and camera pacing, with support for sound generation. When you need high-definition output, character references, and short-shot creation, this is a version worth prioritizing.
Submit requests to the public API at api.acedata.cloud using the documented parameters, then use the results in your application.

Use reference_image to provide a person or subject, then specify the scene, clothing, actions, and camera with text, allowing the reference image to carry identity and appearance cues rather than fixing the entire composition. If you want the video to begin moving from the original image composition, use first_frame instead, which is suitable for turning portraits, product images, or illustrations into dynamic shots.
In addition to images, you can add reference_video and reference_audio to provide cues for motion, camera movement, sound, and rhythm. Text should specify which parts of each asset need to be referenced to avoid conflicting requirements from different assets; when you need a finished video with sound, enable generate_audio so visuals and sound enter the same generation process.
The standard version offers resolution options from 480p to 4k and supports landscape, portrait, square, and ultra-wide formats. You can first validate the subject and motion, then choose a higher resolution to produce delivery shots; use return_last_frame to obtain the final frame, which also makes it easier to preview the ending or prepare visual assets for the next creation.
Start with specific tasks to find where the model can make an impact.
Input a product image and a shot description, such as a slow push-in, sideways movement, or highlighting material details, to generate standalone clips for advertising edits. Use first-frame mode when you need to preserve the starting layout, and reference mode when you need to present the same subject in a new scene, then choose landscape, portrait, or square framing based on placement.
Provide clear reference images of people you own or are authorized to use, and describe the character's behavior in indoor, street, or natural environments to create multiple short shots of the same character. The reference image handles appearance cues, while text handles the scene and actions; this is suitable for character concept presentations and storyboard sequences. Before delivery, check each segment to ensure the character's appearance and actions meet requirements.
Combine example motion videos, rhythmic audio, and scene prompts to explore visual expression for dance, sports, or scenes with ambient sound. First clarify whether you want to draw from the motion, camera work, or sound, generate short videos for the creative team to discuss, then download the videos for the editing workflow, avoiding treating every element in a reference asset as a target that must be copied.
Choose based on task complexity, input materials, and expected results.
When 1080p or 4k output is needed, prioritize this Standard Edition; 2.0 Fast and Mini support 480p and 720p resolutions, making them more suitable for previews and lightweight creation. All three support character and audio/video references, but they are different model variants. Do not assume that simply replacing the name will result in exactly the same parameter combinations and output performance.
This model is suitable for 4–15-second HD short shots and multimodal reference generation. If you need up to 30 seconds, audio-only references, more assets, or to edit and extend existing videos, choose Seedance 2.5. The key trade-off between the two is HD output and workflow type, rather than interpreting the newer version as having higher specifications in every respect.

Answers to common questions about using doubao-seedance-2-0-260128.
reference_image provides clues about a person or subject, while the scene and action can still be redefined with text; first_frame makes the video start from the specified image. To place the same person in a new environment, choose a reference image; to make an existing photo composition come to life directly, choose the first frame. Do not mix the two tags.
Set generate_audio to true and describe the desired sound or ambient audio in the prompt to request a video with sound; this option is disabled by default. If you need reference audio, you must use the audio_url object and the reference_audio tag, while also providing reference_image or reference_video; you cannot upload only reference audio. Sound generation and audio reference are different controls, and uploading audio cannot replace the setting for generating sound; when not using reference audio, you can also describe the desired sound in text.
This version generates videos lasting 4–15 seconds, and you can also use duration=-1 to determine the duration automatically. For up to 30 seconds or editing and extending existing videos, choose Seedance 2.5; adding reference_video is a reference generation method and does not mean editing or continuing the original video.
Submit the exact model ID and content array to POST /seedance/videos. Image items use an image_url object, for example containing url inside it, rather than writing the address directly as a string; use type, role, and text prompts to describe the purpose, and set resolution and duration using top-level fields.
You can set async=true to obtain a task_id and then query the task, or provide callback_url to receive a completion notification. After obtaining the completed result, read data.video_url to download the video; do not treat a successful submission as meaning the finished video is ready. If you need a final-frame image, you can also enable return_last_frame.
