Seedance AI Video Generator

Seedance accepts more than a prompt. You can hand it reference images and audio in the same generation, and it uses all of them to shape the output. Describing a scene in words gets you somewhere close. Showing the model what you mean gets you closer.

Audio comes out of the same generation as the picture, so dialogue lands on the mouth movements and ambient sound matches what is on screen. You skip the step where you drop the clip into an editor and nudge a sound file around until it lines up.

Give it a reference image of a person and that face carries through the scenes it generates. This is what makes multi-shot sequences usable. Without it you get a different-looking person every few seconds, which ends any attempt at telling a story.

Camera angle and movement respond to direction, so you can ask for a push in, a pan, or a cut to a wider framing instead of accepting whatever the model decides. How precisely it follows varies with the prompt, and it takes a few tries to learn what phrasing it responds to.

The lightweight tiers run at 720p, which is enough for social platforms, where everything gets compressed anyway. The standard model goes higher when you need the detail. Clip length covers the short end that social formats use, and longer sequences come from generating shots and joining them.

Mini finishes a clip noticeably quicker than Fast, and it bills at a lower rate per second. ByteDance's benchmarks put the speed gap at roughly double, though what you actually see depends on queue load at the time you run it. The cost difference is wide enough that it changes how you work: when a draft is cheap, you stop treating each generation as something you have to get right on the first try.

On motion coherence and frame stability, the two land close together. Mini holds up about as well as Fast across most prompts despite being the cheaper tier.

Neither goes above 720p. If you need 1080p or 4K, you need the standard Seedance model instead. Past that, the two tiers behave the same way: text to video, image to video, with native audio syncing and clips running from 4 to 15 seconds.

Use Mini for drafts and for any shot you expect to regenerate several times before you keep one. Fast still works, and if you have jobs already pinned to it there is no urgency to move them.

The most common starting point on SwapFace is a still you already made here. Run a face swap or an outfit swap, then feed that image to Seedance and it becomes a moving clip with the same face and the same clothes. The person turns, the fabric moves, the light shifts across them. You keep the edit you spent time getting right and add motion on top of it.

A listing with a short clip holds attention longer than one with flat photos. If you have a product shot or a model image, Seedance can turn it into a few seconds of the garment moving on a body. Sellers running dozens of SKUs use this to get video on every listing without booking a shoot for each one.

Clips in the 5 to 15 second range are what TikTok, Reels, and Shorts run on. Seedance works at that length, so you can go from an idea to something postable in one sitting. Creators use it for concept clips, transitions, and the kind of quick visual gag that would otherwise need a camera and a location.

Before anyone commits budget to a real shoot, a rough moving version of the idea makes it easier to agree on. Seedance clips are cheap enough to make several versions of a scene and let the client pick, which is harder to justify when every version costs a crew day.
