Seedance 2.0 Turns a Prompt or a Photo into 4K Video with Sound
Run the full Seedance 2.0 tier in your browser: the only build in the family that renders 1080p and 4K, with clips of 4 to 15 seconds, six aspect ratios, and generated audio on a switch. All four generation modes sit in the workspace above, free to start and with no watermark.
Delivery-grade 4K • Scenes that run a full 15 seconds • Sound in the same pass • Nothing stamped on
What is Seedance 2.0?
Seedance 2.0 is ByteDance's video generation model, and this page runs its full tier: the build that reaches 1080p and 4K rather than stopping at 720p. Give it a text prompt, a still image, a set of reference images and clips, or a first and last frame, and it returns one continuous shot of 4 to 15 seconds in any of six aspect ratios, with sound generated in the same job when you want it. Everything happens in the workspace above, with nothing to install, no list to join, and no watermark burned into the result.
What the Full Seedance 2.0 Is For
Three things worth spending the flagship tier on, and three answers to what people ask about it most.
- 720p, 480p, 1080p and 4K in one tier
- Mini and Fast both cap at 720p
- Rerun an approved draft at delivery resolution
- Same prompt and references carry over from the draft
Who Uses Seedance 2.0
Filmmakers, short video creators, marketers, sellers, artists, and teaching teams
Independent and AI Filmmakers
Block out a scene, shoot coverage you never filmed, and cut a teaser without a crew or a location. Fifteen second takes at 1080p or 4K are long enough to carry a real beat, and Reference to Video keeps your lead looking like the same person in every shot.
Short Video Creators
Vertical 9:16 for Reels, TikTok, and Shorts, square 1:1 for feeds, and 21:9 when a post should read like a film still. Turn one prompt into a hook, render it with sound, and publish the same afternoon.
Marketers and Ad Teams
Test five versions of a concept before anyone books a studio. Write the script as a prompt, render variants at different lengths and ratios, and take only the winner up to 4K for the paid placement.
Ecommerce and Product Sellers
Start from one product photo in Image to Video and let the camera move around it. Frames to Video handles turntables and before and after shots that have to land on an exact final frame.
AI Artists and Illustrators
Bring finished artwork into motion without redrawing it. Image to Video animates a single piece, and Reference to Video carries your palette, linework, and character design across a whole sequence.
Educators and Explainer Teams
Illustrate a process, a historical scene, or a lab step that nobody can film. Clips of 4 to 15 seconds drop straight into a slide deck or a course module without extra editing.
Why the Full Seedance 2.0 Is Worth the Step Up
Three specs and one honest limitation, and what each means for the work.
4K Is the Difference Between a Test and a Deliverable
Mini and Fast both stop at 720p, which is enough to decide something and not enough to ship it. The full tier reaches 1080p and 4K, so the shot you approved as a draft can be rerun at delivery quality from the same prompt and the same references. Nothing about the idea gets renegotiated in the process.
Fifteen Seconds Is Long Enough to Mean Something
A scene needs an establishing beat, a turn and a resolve. Under ten seconds you get a gesture; at fifteen you get a moment that can carry a story. Combined with the frames mode for chaining, this is the shortest version of the tier that supports narrative work rather than clips.
Nine References Are How a Campaign Stays Coherent
Commercial work is a set of shots that have to agree with each other, not one lucky render. Nine images plus reference clips and audio pin the face, the garment, the packaging and the room at once, which is the mechanism that turns separate generations into something recognisably the same campaign.
No Seed Means References Carry the Consistency
Seedance does not expose a seed, so reruns are fresh takes rather than controlled variations. Identity has to come from the reference set and from a prompt block you reuse verbatim. Once you build that habit the absence stops mattering, but it is worth knowing before you plan a sequence around reproducibility.
How to Use Seedance 2.0 in Four Steps
From an empty prompt box to a finished clip you can download
Open the Seedance 2.0 Generator
Scroll to the generator at the top of this page and sign in. Seedance 2.0 is already selected as the model, so there is nothing to configure before your first render.
Pick One of the Four Modes
Choose Text to Video, Image to Video, Reference to Video, or Frames to Video. Image to Video takes a single picture, Frames to Video takes an opening frame and a closing frame, and Reference to Video accepts up to 9 images alongside short video and audio references.
Write the Prompt and Set the Output
Describe subject, action, camera movement, and lighting in your own words. Then choose 480p, 720p, 1080p, or 4K, set a length between 4 and 15 seconds, pick one of the six aspect ratios, and decide whether the audio switch is on.
Render, Review, and Download
Start the job and watch the result appear in the workspace. Keep the take you like, or change one line of the prompt and run it again if you do not, then download the finished clip with no watermark on it.
Frequently Asked Questions About Seedance 2.0
Free access, 4K output, clip length, audio, references, the API question, and the rest of the lineup
Seedance 2.0 is the full tier of ByteDance's Seedance video generation family, and the one that reaches the highest output quality. It builds video from a text prompt, a single image, a set of references, or a pair of start and end frames, at 480p, 720p, 1080p, or 4K, in lengths from 4 to 15 seconds. People also type it as seedance 2, seedance2.0, seeddance, or seadance when they search, and all of those point at the same model.
Open the generator at the top of this page, sign in, and start a render. There is no waitlist, no install, and no access form to fill in. Free renders are the normal way to try the model here, and nothing you download carries a watermark, so a test clip is still usable. Draft at 480p or 720p while you tune the prompt, then send the take you like back through at 1080p or 4K.
Yes. This tier offers 480p, 720p, 1080p, and 4K, with 720p selected by default. It is the only build in the Seedance 2.0 family that goes past 720p, which is why it is the one to use for client work, paid placements, and anything headed for a large screen. Choose the resolution in the generator before you render.
Anywhere from 4 to 15 seconds, adjustable one second at a time. Fifteen seconds is the ceiling for a single generation, and it is long enough for a complete beat with a setup and a payoff. For a longer sequence, render several clips and hold them together by reusing the same reference material, then assemble the cut in your editor.
Four steps. Open the generator on this page and sign in, pick one of the four modes, write your prompt and set resolution, duration, aspect ratio, and the audio switch, then render and download. The prompt box accepts up to 20,000 characters, so describe the shot the way you would brief a camera operator: subject, action, camera movement, lighting, and mood.
Resolution and clip length. The mini build keeps the full 15 seconds but tops out at 720p and opens at 480p. The fast build renders at 720p or 480p and caps clips at 10 seconds, trading length for turnaround. The full Seedance 2.0 on this page is the only one that reaches 1080p and 4K while still allowing 15 seconds. If you have been reading comparison threads on Reddit, the short version is that anything above 720p means this tier.
Yes. Audio generation is a switch in the generator, and it sits off by default. Turn it on and the sound is produced in the same job as the picture, so there is no second pass in an editor. In Reference to Video you can also upload up to 3 audio files, 15 seconds in total, as MP3 or WAV, to steer the sound the render aims for.
Plenty of people search for seedance api because they want to run the model without building a pipeline first. The generator on this page is that shortcut: the same Seedance 2.0 engine, with mode, resolution, duration, aspect ratio, and audio exposed as controls, and no key to provision or code to write. Test your prompts here before you commit engineering time to anything larger.
Use Reference to Video. Give it up to 9 images of the same character, plus up to 3 short video references if you have footage, and Seedance 2.0 reads them as an identity and style guide for the render. That covers what the camera sees: the face, the outfit, the palette, and the set. It is visual consistency rather than a guaranteed voice match, so lock dialogue and voice in your editor when a scene depends on them.
Nothing rendered through this page is stamped with a logo or a badge. The clip you download is the clip you can post, publish, or hand to a client, with no corner to crop and nothing to cover up.
Clips you generate here are yours to use in commercial work such as ads, social campaigns, client deliverables, and product pages, and they arrive without a watermark. Because the underlying model belongs to ByteDance, check the terms that apply to your plan and to the platform you publish on before a render goes into a regulated category, and keep your uploaded references clear of material you do not hold the rights to.
Yes. Seedance is ByteDance's video generation line, the same research that sits behind its Dreamina and CapCut creative tools, and Seedance 2.0 is the current generation of it. This page gives you that model in a browser workspace with the mode, resolution, and duration controls exposed. However you spell it, as sedance, seed dance, or seedence, the model underneath is the same one from ByteDance.
