About Seedance 1.0

Seedance 1.0 is the first generation of ByteDance's Seedance video models, and it was built for stability. Subjects keep their shape through large movements, from a runner in mid-stride to a chef tossing a wok, and when one prompt asks for several shots, the clip keeps the same main subject, style and atmosphere across the cuts. It works from text alone or from a first-frame image, in styles that range from photorealism to illustration.

This page covers Seedance 1.0 Pro and Seedance 1.0 Fast, and you switch between them with the model button in the editor. Seedance 1.0 Fast is the newer of the two and costs less per second; ByteDance says it builds on the rich detail and material realism of Pro, with more expressive faces and hair. A good routine is to draft with Fast, compare a take on Pro when a shot matters, and keep whichever look you prefer.

Seedance 1.0 is the Seedance version you can use on the free plan. 480p is available to free accounts, while 720p and 1080p need Plus or above. Videos made on the free plan are for personal, non-commercial use only, so move to a paid plan before a clip goes into an ad, a shop or client work. For a stronger film look, Seedance 1.5 Pro is the next step up in the family.

What Seedance 1.0 does well

The same person in every frame

Seedance 1.0 keeps the main subject steady through a clip, including across cuts when one prompt asks for several shots. ByteDance built it to hold the subject, the visual style and the atmosphere through shot transitions. The cyclist sample shows the goal: the same face, green jacket, grey helmet and bicycle as she rides past a bakery, turns beside a canal and stops at a traffic light to look back. Describe the character once in full, then repeat the same key details in each shot. Starting from an image of the character as the first frame makes the look even easier to hold.

Same face, hair, jacket, helmet and bicycle in all three frames, bright daylight, thin black borders.

Fluid movement

Large movements are where Seedance 1.0 does its steadiest work. ByteDance describes a wide dynamic range: from a small change of expression up to a full-body move, the motion stays smooth and physically believable. A parkour vault like the sample is a good test, with one hand on the wall, the body horizontal in mid-air and the hoodie rippling with the motion. Write the movement as a sequence, such as "runs, plants one hand, swings both legs over, lands", rather than a single verb, and a low side angle keeps the whole arc of the body in frame.

Smooth, athletic, crisp subject against a softly blurred urban background.

Fast action, stays clear

Fast subjects stay readable in Seedance 1.0 instead of dissolving into blur. For the Fast version, ByteDance points to stable footage in extreme-sports scenes that follows physical laws and avoids distortion and artifacts. A border collie leaping for a frisbee is a good example: the fur, the flying ears and the kicked-up grass should stay sharp while the background carries the motion blur. Put the peak of the action in the prompt, name the camera, such as "tracking at a low angle", and keep the background simple so the detail goes into the subject.

Limitations to know

  • Lettering inside the frame is not reliable. Signs, jersey numbers and shop names tend to smear or change between frames, so leave on-screen text out of the prompt and add titles in an editor afterwards.
  • Close contact between several people, such as a dance couple or a crowded tackle, is harder than one moving subject. Hands and limbs can merge where bodies touch, so check those shots frame by frame before you use them.
  • At 480p, small details soften: faces far from the camera, fine patterns and thin lines lose definition. Keep the subject large in the frame when you work at the free resolution.

How to write prompts for Seedance 1.0

  1. Start with one subject and one clear action; Seedance 1.0 is steadiest when the movement has a single focus.
  2. Break a big movement into steps, such as take-off, peak and landing, so the model knows the shape of the motion.
  3. Name the camera: "side tracking shot matching her pace", "low angle" or "static wide shot". A camera that follows the subject keeps it sharp.
  4. For several shots in one clip, describe each shot in order and repeat the character's key details in each one.
  5. Test ideas on Seedance 1.0 Fast at 480p, then render the take you like at a higher resolution.
