Question 1

What is Seedance 2.0?

Accepted Answer

Seedance 2.0 is a Bytedance video generation model for creating AI videos from text prompts, keyframe images and multimodal references. It is useful for cinematic shots, product motion, social clips, storyboards and reference-guided scene exploration.

Question 2

Which generation modes does Seedance 2.0 support?

Accepted Answer

This generator supports Text to Video, Image to Video and Multi Reference. Text to Video starts from a prompt only, Image to Video uses uploaded keyframes, and Multi Reference lets you guide the result with image, video and audio references.

Question 3

How should I choose between Seedance 2.0 Fast and Seedance 2.0 Quality?

Accepted Answer

Use Fast when you want cheaper, quicker drafts at 480p or 720p. Use Quality when the final clip needs stronger detail, more polished motion or 1080p output.

Question 4

What resolutions and durations are available?

Accepted Answer

Seedance 2.0 Fast supports 480p and 720p, while Seedance 2.0 Quality supports 480p, 720p and 1080p. The current generator lets you choose a duration from 4 to 15 seconds before submitting.

Question 5

Which aspect ratios are supported?

Accepted Answer

Seedance 2.0 supports 1:1, 4:3, 3:4, 16:9, 9:16, 21:9 and adaptive aspect ratios.

Question 6

How do I write a better Seedance 2.0 prompt?

Accepted Answer

Describe the subject, setting, action, camera movement, lighting, style, mood and audio direction. Prompts such as “slow dolly-in, warm practical lights, handheld documentary feel, realistic crowd ambience” usually give the model clearer production intent than a short noun phrase.

Question 7

How does Image to Video work?

Accepted Answer

Upload a first frame to define the opening composition. You can also add a last frame to guide where the motion should end, which is helpful for transitions, product reveals and character movement.

Question 8

What can I provide in Multi Reference mode?

Accepted Answer

Multi Reference mode can use up to 9 reference images, up to 3 public video URLs and up to 3 public audio URLs. Images are best for visual style and subject identity, video references are best for motion rhythm, and audio references help communicate timing or ambience.

Question 9

Can Seedance 2.0 use a real person as a reference?

Accepted Answer

Yes. You can use authorized real-person photos as reference images to guide the subject’s appearance, outfit, styling and on-camera role. For best results, use clear images of the person and describe how they should move, where they are, and what cinematic style you want.

Question 10

Do video and audio references need to be public URLs?

Accepted Answer

Yes. Reference video and audio inputs should be accessible public URLs so the generation service can read them. If a URL requires login, blocks hotlinking or expires too quickly, the task may fail.

Question 11

What do Generate Audio, Web Search and Return Last Frame do?

Accepted Answer

Generate Audio asks Seedance to create audio with the video. Web Search can provide extra grounding for the prompt when supported by the model path. Return Last Frame requests the final frame image along with the video result when the API returns it.

Question 12

How are credits calculated for Seedance 2.0?

Accepted Answer

Credits depend on the selected model, resolution, duration and whether video input is involved. The generator calculates the cost before submission and shows the required credits next to your remaining balance.

Question 13

Where can I find my generated Seedance videos?

Accepted Answer

Finished Seedance 2.0 videos are saved into your generation history. You can open recent Seedance results from the History tab on this page or view the full history from the main history page.

Question 14

Why did my Seedance 2.0 generation fail or take longer than expected?

Accepted Answer

Failures are usually caused by invalid reference URLs, unsupported media formats, expired files, insufficient credits or temporary provider queue delays. Try simplifying the prompt, checking that reference URLs are public, reducing reference inputs or retrying after a short wait.
