ByteDance multimodal video model

Seedance 2.0 AI Video Generator

Combine text, first or last frames, and multimodal references with Seedance 2.0. Set a 4–15 second duration, direct the sound, and choose the format for your scene.

Text, image, video, and audio references · 4–15 second scenes · Optional generated audio

Direct the relationships, not just the ingredients

A useful multimodal brief names what each asset supplies and how those signals meet inside the same 4–15 second scene.

Write the outcome first

Define the audience, format, story beat, and most important action before selecting supporting material.

Choose a compatible reference mode

Use first or last frames for strict endpoints, or use multimodal references for subject, motion, pacing, and sound guidance. The generator prevents incompatible combinations.

Connect picture and sound

Explain when dialogue, ambience, music, or effects should occur in relation to the visible action.

Review against the brief

Check requested actions, reference use, subject continuity, scene logic, and audio alignment before iterating.

Use the model intentionally

Choose this workflow when

This workflow coordinates action, camera, references, and sound rather than treating them as separate afterthoughts.

Where multimodal direction helps

Combine text, first or last frames, and multimodal references with Seedance 2.0. Set a 4–15 second duration, direct the sound, and choose the format for your scene.

Before generating

Choose one compatible input mode and useful references

Inside the prompt

Assign each asset a role in motion, camera, or sound

After generation

Check continuity, detail stability, and audio timing

Reference-led campaign scenes

Coordinate a product or character reference with a planned camera move, environment, and audio cue.

Rhythm and performance concepts

Describe how movement, cuts, ambience, dialogue, or effects should meet specific moments in the scene.

Continuation and edit planning

Use first and last frames or multimodal references to state what should continue and what should change.

Seedance 2.0 workflow questions

ByteDance multimodal video model

When should I choose Seedance 2.0?

Choose this multimodal workflow when text, images, video clips, or audio cues need to guide one scene together. Add each reference with a clear role, then review the duration, format, sound setting, and credit estimate before generating. For a task that starts from only one idea or one image, the dedicated text-to-video or image-to-video route may be easier to direct.


Can I combine different reference types?

Yes, when multimodal reference mode is selected. The standard workflow accepts up to 9 images, 3 videos, and 3 audio files; first-and-last-frame mode is a separate choice. Upload only assets with a specific job, use @ mentions to connect them to prompt directions, and confirm the displayed limits before submitting the task.


What should I review before keeping a clip?

Compare the clip with the brief and source assets. Check requested action, subject continuity, small details, camera logic, text inside the frame, and the timing or clarity of sound. Watch the full video once for story flow, then inspect key moments more closely. Save the useful version in My Creations before starting a substantially different direction.


How should I assign roles to image, video, and audio references?

Give each reference one primary responsibility. An image can define a character or product, a video clip can demonstrate movement or camera rhythm, and an audio file can establish timing or atmosphere. Mention the asset directly in the prompt and describe how its role connects to the scene. Avoid asking several conflicting references to control the same visual decision.


When are first and last frames better than mixed references?

Choose first and last frames when the clip must begin and finish on specific visual states, such as a transformation, transition, or planned edit point. Choose mixed references when identity, motion, style, and sound come from different assets. Because the input modes solve different problems, decide whether endpoints or creative signals matter more before uploading.


How do I prompt a coherent scene with several references?

Write one sentence for the scene objective, then connect each @ reference to a concrete task. Describe the order of visible actions, the camera path, and the sound timeline. End with the visual state the shot should reach. If the brief becomes difficult to summarize, remove any asset that does not change an important creative decision.


What is a useful way to plan a 4–15 second scene?

Divide the clip into a beginning, development, and ending beat without overcrowding the duration. Introduce the subject and action quickly, reserve the middle for the main movement, and use the final moment for a clear hold, reveal, or transition. Short scenes benefit from one readable objective instead of several unrelated story events.


How can I improve audiovisual synchronization?

Describe sound cues relative to visible events: a line begins as the character turns, an impact lands when an object touches the surface, or ambience changes as the camera enters a room. Review the result with sound on and off. If timing misses, keep the visual brief stable and revise the cue language before changing references.


How do I keep a character or product consistent across the shot?

Choose high-quality references that agree on the key identity details, then name the features that must remain recognizable. Avoid unnecessary costume, lighting, or angle changes during the first pass. Check the subject at the beginning, midpoint, and end; refine the most visible continuity issue before expanding the action or camera movement.


How should a team review a multimodal generation?

Use the original brief as a shared scorecard. Review reference fidelity, action clarity, camera logic, sound timing, technical artifacts, and fit for the delivery channel. Separate must-fix issues from optional polish, record the prompt and settings, and agree on one revision priority. This keeps feedback actionable and protects useful decisions from being lost between versions.


Direct one coherent audiovisual scene

Choose available inputs deliberately, explain how they work together, and review the output against the same brief.
