How Seedance 2.0 Generates Dance Motion From a Photo

The model behind every render in the studio is Seedance 2.0, served at the standard tier. This guide explains how that model turns a still photo or a written prompt into a short dance clip, how it holds onto the subject, where the motion starts to break, and what the standard tier costs on this site.

What Seedance 2.0 is in this studio

Seedance 2.0 is a ByteDance video generation model. This site runs it through kie.ai using the model id bytedance/seedance-2. The studio does not train its own model, and it does not repackage a social media filter. It sends your input to the hosted model and returns the clip to your account.

You can generate in two input modes. Photo mode is image-to-video: one still image plus an optional text description. Text mode uses only a written prompt. Both paths produce an MP4 at the resolution and length you select. Renders stay private to the account that created them.

Two input paths and what they change

Photo-to-video is the path most dance renders use. The uploaded image acts as a visual anchor for the subject, and the text prompt tells the model what movement to produce. Text-to-video skips the image and builds the person, animal, or scene from the prompt alone.

| Input mode | What you provide | What Seedance 2.0 does | Strongest use case | | -------------- | ---------------------------------------------------- | ---------------------------------------------- | ----------------------------------------- | | Photo to video | One JPG, PNG, or WebP up to 10 MB plus optional text | Generates motion around the uploaded subject | A selfie or pet photo that needs to dance | | Text to video | A written prompt between 10 and 2,000 characters | Builds subject, setting, and motion from words | No usable photo is available |

In photo mode, the prompt can be left empty if you pick one of the four looks. The look supplies the movement description. In text mode, the words have to do everything, so describing the dancer, the setting, and the camera angle matters more.

How the model keeps identity from a still photo

A clean reference photo gives Seedance 2.0 a fixed starting point for facial structure, hair, clothing, or fur markings. As frames are generated, the model keeps pulling from that starting image, which is why the moving figure still reads as the same person or pet.

Identity retention is not automatic. The model works best when the photo is sharp, well lit, and contains one person or one animal from the front or a three-quarter angle. Waist-up or whole-body framing gives the arms and legs room to move. Blurry photos, group shots, or a photo where the face is turned away create a worse anchor point, and the output may show drifting limbs or an unstable face between frames.

Why one clear action and a short clip produce better motion

Dance is a single continuous action, not a sequence of cuts or poses. Seedance 2.0 has to sustain that motion across the entire clip without keyframes. If a prompt asks for two or three different moves in the same render, the model has to blend them into one continuous sequence. That is where the action can become muddy and the subject can slip.

The studio offers 5, 8, 10, and 12-second renders. The provider accepts a 4 to 15 second range, but the studio stays within the shorter portion of that range because a short action is easier to keep stable from start to finish.

The same rule applies to the dance itself. A single clear movement, repeated with the rhythm, is more likely to read as the Wipe Me Down dance than a full routine packed into one clip. Keep the instruction narrow and let the model stay inside that boundary.

Motion limits and artifacts to expect

Every tier has edges. Knowing them before you spend credits reduces wasted renders.

• The provider range is 4 to 15 seconds, but this studio only exposes 5, 8, 10, and 12 seconds. A 15-second clip is not offered here.
• Resolutions top out at 1080p. There is no 4K tier on this site.
• The model does not accept a video input. It cannot take an existing clip and transfer that motion onto your subject.
• The prompt and the reference image are not a script-plus-storyboard pair. The photo anchors the subject, and the text guides the action.
• Only the standard tier is offered. A premium tier with different motion behavior is not part of this product.

The main artifacts described by the studio are limb drift and face changes between frames. These are more likely when the source photo is poor or when the prompt asks for too many movements at once. A failed render returns its credits automatically, so retrying does not double-charge.

What the standard tier means on this site

The studio keeps one tier so the price stays legible. The default render is Standard 720p 12 seconds for 26 credits. A 480p clip costs 12 credits for the same 12 seconds, and 1080p costs 64. Longer durations scale from the 12-second table and are rounded up to a whole credit. The credit badge next to the Generate button recalculates whenever you change a setting.

New email accounts start at zero credits. A single pack costs $9.90 and contains 10 credits, which is not enough for a standard 720p 12-second render. The smallest pack that covers one standard render is the Duo Pack at $19.90 with 30 credits.

Each account gets one free preview render at 480p for 5 seconds while the daily preview budget lasts. Google sign-in accounts can claim 10 free credits a day for three days. There is no unlimited or free-forever plan.

The full credit menu is on pricing.

A short pre-render checklist

1. Use a sharp, well-lit photo of one person or pet, taken from the front or a three-quarter angle.
2. Choose one action, not a routine.
3. Keep the clip at 5 or 8 seconds if you are testing a prompt or working with a difficult photo.
4. Leave the prompt empty in photo mode only if the selected look already matches the motion you want.
5. Check the credit badge before generating so the resolution and duration fit your balance.
6. Use the free 480p preview render if it is still available before spending credits on 720p or 1080p.

FAQ

Does Seedance 2.0 take a video input?

No. This studio accepts a still photo or a text prompt. It does not accept a reference video, and it does not transfer a recorded dance from a clip onto your subject. Every render is a new generated performance.

Is the model the same for people and pets?

Yes. The same standard tier handles human and animal subjects. A clear single-subject photo helps the model lock onto human facial features or animal fur patterns, ears, and proportions.

Why does the studio only show 5, 8, 10, and 12 seconds when the provider can do more?

The provider range is 4 to 15 seconds. The studio uses 5, 8, 10, and 12 seconds because shorter clips with a single action keep motion more stable. A 15-second option is not offered here.

What happens if a render fails?

Credits return automatically to the balance they came from. A render that was never produced is not charged, and retrying does not double-charge. If failures continue, shorten the clip or simplify the action.

Can I try before paying?

Yes. Each account gets one free preview render at 480p for 5 seconds while the daily preview budget lasts. Google sign-in accounts can claim 10 free credits a day for three days. Email sign-up starts at 0 credits. There is no unlimited or free-forever plan.
