Question 1

What can I make with Seedance 2.0 Fast?

Accepted Answer

Storyboards, ad iterations, social content, music video drafts, character animation, and any clip you want to iterate on quickly without spending a lot per try. Anything that begins with a prompt and ends in a finished clip. Animate a still image into a full scene. Pin the opening and closing frames. Bring a character sheet into motion. Generate sound and dialogue alongside the picture. Strong with realistic physics, weight, lighting, and camera movement.

Question 2

Can I animate an existing image with Seedance 2.0 Fast?

Accepted Answer

Yes. Upload a starting image and describe what should happen. Seedance 2.0 Fast turns the still into a moving scene with consistent subject, lighting, and composition. You can also pin a last-frame image and let the model interpolate the motion between the two. A natural fit for product shots, character intros, and stylized transitions where you want exact control over how the clip starts and ends.

Question 3

Can Seedance 2.0 Fast keep characters consistent across shots?

Accepted Answer

Yes. Attach up to nine reference images of the character and the scene. Seedance 2.0 Fast holds the same face, body, outfit, and styling across new compositions. You can also attach reference videos to guide motion, or reference audios to drive lip-sync. A strong choice for storyboards, episodic content, and brand campaigns where the same character has to appear across many shots.

Question 4

Does Seedance 2.0 Fast generate audio and dialogue?

Accepted Answer

Yes. Toggle audio generation in the composer and Seedance 2.0 Fast produces sound, ambient noise, and synced dialogue alongside the picture. You can also attach a reference audio clip and the model will lip-sync the character to it. The result lands as a single video file with sound baked in, so you can drop it straight into an edit.

Question 5

What is the difference between Seedance 2.0 Fast and Seedance 2.0?

Accepted Answer

Seedance 2.0 Fast is the speed tier. It renders quickly, costs less per second, and tops out at 720p. Seedance 2.0 is the full-fidelity tier from the same model family. It supports 480p, 720p, and 1080p, and produces the cleanest motion and detail. Use Fast for storyboards, ad iterations, and high-volume work. Use the full Seedance 2.0 for hero shots and final delivery. Both share the same prompt and input interface in Visual Sandbox, so you can switch between them on the same project.

Question 6

What aspect ratios and resolutions does Seedance 2.0 Fast support?

Accepted Answer

Square, portrait, landscape, and wide cinematic ratios. Common picks include 16:9 for landing pages and trailers, 9:16 for shorts and reels, 1:1 for social feeds, and 21:9 for cinematic frames. Resolutions are 480p and 720p. For 1080p output, switch to the full Seedance 2.0 in the composer.

Question 7

How long can a Seedance 2.0 Fast video be?

Accepted Answer

Up to fifteen seconds in a single generation. You can also leave the duration on auto and let the model pick a length that suits the prompt. For longer pieces, chain multiple clips in Visual Sandbox by feeding the last frame of one clip in as the first frame of the next. That keeps the look and motion continuous across the cut.

Question 8

How do I write prompts that work well with Seedance 2.0 Fast?

Accepted Answer

Be specific about the subject, the camera, the lighting, and the motion. Describe what is in the frame, then how the camera moves, then how the subject moves. A locked camera with a moving subject usually reads cleaner than moving both at once. For character work, attach reference images. For motion or pacing, attach a reference video. Short prompts work for simple ideas. For cinematic shots and ad creative, longer prompts with structured detail produce more consistent results.

Question 9

How much does a Seedance 2.0 Fast video cost?

Accepted Answer

Seedance 2.0 Fast is billed per output second. The pricing table above shows the rate at each resolution, and the small premium when you attach a reference video. Visual Sandbox shows the exact cost before you generate, and charges per clip when the result is delivered. There is no subscription, no monthly minimum, no top-up.

Question 10

Can I use Seedance 2.0 Fast videos commercially?

Accepted Answer

Yes. ByteDance's Seedance 2.0 terms allow commercial use of generated videos. You are responsible for the prompt and the final use, especially when the output includes likenesses, logos, or copyrighted material. The model is widely used for ad creative, social campaigns, and short-form content on Visual Sandbox.
