Put it to work
Each clip here came from the prompt behind its button. Load it, swap in your subject, and render your own take.
Show a director, a client or a producer the feeling you are after before a single day of shooting. Wide 21:9 frames and a soundtrack make it read like a scene.
Describe the material, the surface and every cut. Mini handles macro push-ins and clean top-down shots, and the click of a lid lands in the audio.
Start from a character image and give them something to do. Feed several references when they need to meet a second character or a set.
Three steps
Subject, action, camera, sound. Add one image for the opening frame, two for start and end, more as references, or a clip and an audio file to follow.
4 to 15 seconds, 720p or 1080p, six aspect ratios from 21:9 to 9:16. The button shows the exact credits before anything is charged.
Finished clips land in your library with their soundtrack. Upload one again and choose Edit to change the weather, the style or the subject.
On Seedance21
Seedance 2.0 Mini is the faster, cheaper member of ByteDance's Seedance 2.0 family. Seedance21 wires all four of its turbo endpoints to a single prompt box and picks one from what you attach.
16 credits a second at 720p, 20 at 1080p, any length from 4 to 15 seconds. Reference clips and edits add a smaller charge for the seconds they read.
Every clip comes back with an audio track. Name the ambience, the music or the footsteps in your prompt. When you edit a clip, switching sound off keeps your original audio.
Write "cut to" between shots and the model cuts, keeping the character and the light consistent. Good for a short sequence instead of a single moving photo.
Our server sets the price before a render starts. A run that fails or is refused hands every credit back to your balance automatically.

FAQ
Create an account, type the scene and press the button. Attachments decide the job: one image animates it, two can be first and last frame, more act as references, and a clip can be edited or followed. Results go to your library.
A video model from ByteDance, released in June 2026 as a lighter member of the Seedance 2.0 family. BytePlus put its price at about half of Seedance 2.0. It takes text, images, video and audio references and renders sound with the picture. Seedance21 runs it through WaveSpeed.
Seedance 2.0 Mini is the default: longer clips (4 to 15 s), 1080p, six shapes, audio and video references, and editing. Grok Imagine Video stays in the menu for its own look and its Extend option, which adds seconds to a clip.
Up to 9 images, 3 video clips and 3 audio files per run, the limits most API platforms list for Mini. Clips and audio may total 15 seconds each. Name them in the prompt as @Image 1, @Video 1, @Audio 1 in upload order. Photos of real faces may be rejected.
New accounts get enough credits for one 5-second 720p clip. After that, every render is paid with credits from a plan or a one-off pack.
Yes. Audio is rendered together with the picture, so ambience, music and effects you describe end up in the file. All of our test clips came back with a soundtrack. Listen before publishing, since results vary.
Yes. Upload a clip, keep Edit selected and write the change. Up to 15 seconds are read; longer files are trimmed. You pay for the seconds read plus the seconds produced.
16 credits a second at 720p and 20 at 1080p, so the default 5 seconds is 80 credits. With a reference clip or an edit, input and output seconds cost 7.5 credits each, plus 4 or 8 per output second. The button shows the total first.
Any whole number of seconds from 4 to 15, in 16:9, 9:16, 4:3, 3:4, 1:1 or 21:9. The model renders natively up to 720p; WaveSpeed's 1080p option adds an upscale step. Starting from an image or editing a clip, the output follows your input's shape.
That depends on ByteDance's and WaveSpeed's current terms, which we cannot settle for you. Read them before client work, and leave out real people's likenesses, other companies' brands and material you have no rights to.
No. Seedance21 is an independent website that calls Seedance 2.0 Mini through the third-party API platform WaveSpeed. ByteDance does not make, endorse or partner with it.
Your free credits cover one 5-second clip. Use them on a scene you actually need and judge the result.
