Question 1

What is the Seedance AI video generator?

Accepted Answer

It's an online tool that turns text prompts or images into short, cinematic videos with synchronized sound, powered by ByteDance's Seedance models. Seedance 2.5 is selected by default; Seedance 2.0 and 2.0 Mini are one click away in the model picker.

Question 2

What input modes are supported?

Accepted Answer

Two modes: Text to Video, where you describe the shot in words, and Image to Video, where you upload one reference image to animate — or up to 30 on Seedance 2.5 to blend characters, products and styles into a single shot.

Question 3

What's the difference between Seedance 2.5 and Seedance 2.0?

Accepted Answer

Seedance 2.5 generates one continuous take of up to 30 seconds, handles spoken dialogue with matched lip-sync, and reads references more accurately — at 480p or 720p. Seedance 2.0 tops out at 15 seconds but renders up to 1080p and native 4K (2160p). Pick 2.5 for longer, sound-led storytelling and 2.0 when you need maximum resolution.

Question 4

What resolutions can I generate?

Accepted Answer

Seedance 2.5 renders at 480p or 720p. Seedance 2.0 adds 1080p and native 4K (2160p). 1080p and 4K are paid-plan features, and 4K needs the Standard or Pro plan.

Question 5

How long can the videos be?

Accepted Answer

Seedance 2.5 runs from 5 to 30 seconds as a single continuous shot. Seedance 2.0 and 2.0 Mini run 5 to 15 seconds. Longer durations use more credits.

Question 6

Does it generate sound?

Accepted Answer

Yes. Seedance generates synchronized ambience, foley and music in step with the footage. On Seedance 2.5 the audio is created in the same pass as the picture and can include spoken dialogue with matched lip-sync — put the line in double quotes in your prompt. You can also turn audio off.

Question 7

Which Seedance models can I choose?

Accepted Answer

Seedance 2.5 (the default), Seedance 2.0, Seedance 2.0 Fast and 2.0 Mini for quicker, cheaper drafts, and the older Seedance 1.5 model. Fast and Mini are available on paid plans, as are all 1080p and 4K renders.

Question 8

How does Image to Video work?

Accepted Answer

Switch to the Image to Video tab and upload a photo — Seedance uses it as the starting frame and adds natural motion, camera movement and optional sound. On Seedance 2.5 you can upload up to 30 reference images instead: with two or more, the model blends your characters, products and styles into one shot rather than animating a single frame, and a prompt is required. Seedance 2.0, 2.0 Fast, 2.0 Mini and Seedance 1.5 take one starting image.

Question 9

How are credits calculated?

Accepted Answer

Credit cost scales with the model, resolution and clip duration you choose — Mini is the cheapest way to iterate, while 2.5 and 2.0 cost more per second. The estimated cost is shown before you run a generation.

Question 10

Is there a free trial?

Accepted Answer

Yes — you get one free generation when you sign up, so you can see how prompting and rendering work here before choosing a plan. Paid plans unlock the Seedance 2.5 and 2.0 models, higher resolutions and longer clips.

Question 11

How do I sign in?

Accepted Answer

Sign in with your Google (Gmail) account. There's no password to manage — one click and you're generating.

Question 12

Why did my generation fail, and what can I do?

Accepted Answer

Most failures come from an unclear prompt, an unsupported reference image, or a temporary model timeout. Simplify the prompt, re-upload a standard JPG or PNG, and try again — failed runs don't consume credits.
