      "text": "[Style] National Geographic African Wildlife documentary, 4K Ultra HD, ultra-telephoto lens (800mm Telephoto), high-speed tracking vehicle (Tracking Vehicle 120fps), golden hour light on the East African savanna. [Duration] 10 seconds. [Scene] Dusk on the East African savanna, golden dry grass waist-high, a giant acacia tree silhouetted against the skyline, the sun hanging low on the horizon bathing the entire plain in deep gold, heat haze distorting the distance. [00:00-00:04] Shot 1: Eyes in the grass (Telephoto Close-Up 800mm, Shallow DOF). Ultra-telephoto shallow depth-of-field close-up: golden grass fills the entire frame, with no animal visible at all. Suddenly, through a gap in the grass, a pair of amber eyes appears—a female cheetah crouched low in the grass, only her eyes to the tips of her ears rising above the blades. The black tear marks on her face run from the inner corners of her eyes down to the corners of her mouth, her nose rough black leather in texture. Her pupils contract sharply into vertical slits—locking onto prey. Her ears press slightly back, flattening against her skull. The foreground and background grass blur into golden bokeh, leaving only the cheetah's eyes razor-sharp and clear. [00:04-00:07] Shot 2: Full burst (High-Speed Tracking 120fps, Side Profile). High-speed side tracking shot: the cheetah explodes from the grass into a full sprint, reaching 100 kilometers per hour. In slow-motion, her spine bends like a spring to its extreme then fully extends—curving so that her hind legs pass her front legs, then stretching her body into a horizontal line with all four paws airborne. With each push-off, the dry grass and red earth beneath her paw pads are kicked up in fan-shaped sprays. The white short fur on her belly ripples in waves with the rhythm of her stride, her tail swinging to one side like a rudder during high-speed turns to maintain balance. Her facial muscles are taut, her mouth slightly open revealing canines, nostrils flared wide. [00:07-00:10] Shot 3: Conclusion in dust (Super Slow-mo, Head-On Tracking). Head-on ultra-slow-motion tracking shot: the cheetah charges straight toward the camera at full speed, kicking up a three-meter-high trail of golden dust behind her. She abruptly pivots sideways—all four paws gouging four furrows in the ground, her body nearly rolling horizontal to the earth, her tail arcing in the opposite direction. In the instant of the turn, the dust she throws up forms a curved golden wall, the setting sun backlighting it, illuminating each particle as floating golden stardust. The cheetah's silhouette bursts out from the dust wall and gradually dissolves into the golden rays of the setting sun."

From first test to production

Use the same request contract in the Playground and API, then handle validation, balance, task state, and output retrieval explicitly.

Request lifecycle

  1. 1

    Validate the model, prompt, references, and output settings.

  2. 2

    POST the request and retain the returned task ID.

  3. 3

    Poll task status or process the configured callback.

  4. 4

    Fetch the generated file from the content endpoint and store it before expiry.

Production checks

Parameter validation

Reject unsupported sizes, durations, ratios, formats, or reference counts before submitting.

Authentication and balance

Handle invalid keys, insufficient balance, rate limits, and account-group pricing separately.

Input or policy rejection

Surface the rejected prompt or asset clearly so the user can replace only the failing input.

Task failure or timeout

Keep the task ID, use bounded retries, and never treat a timeout as a successful generation.

Prompt library

seedance-2.0 video generation prompt examples

Start with a seedance-2.0 prompt for short-form creator clips, then adjust the request fields shown in the playground.

Micro-drama and comic creators

Generated with Seedance 2.0

Creative direction: An original hand-drawn adult woman in a yellow raincoat waits on a rain-soaked railway platform beside a red umbrella. She opens and reads a white letter; the camera pushes from the platform view into her worried close-up and holds on her reaction. Visual treatment: Rainy anime drama with cool platform light and yellow-red costume accents. Shot sequence: 1. Establish the yellow raincoat and red umbrella on the wet platform.; 2. Move closer as the woman opens the white letter and lowers her gaze.; 3. Hold her worried close-up with the letter still below her eyeline. Continuity: Keep the character's face, clothing and key prop consistent; preserve screen direction across cuts. Exclude: extra people or props, text, logos and watermarks.

Creative direction: A coral-orange insulated bottle stands on a wet dark-teal studio surface beside a clear glass and a few ice cubes. One adult hand unscrews the cap and pours cold water over the ice, then sets the bottle beside the filled glass. End on a clean product hero frame with both bottle and glass visible. Visual treatment: Photoreal product commercial. A soft overhead key reveals the matte coral finish; a cool cyan edge light picks out condensation and the restrained floor reflection. Shot sequence: 1. Open on condensation and ice in a tight detail shot; 2. Cut to a steady three-quarter view for the cap opening and single pour; 3. Settle on the bottle and chilled glass together, with the bottle silhouette unobstructed Continuity: Keep the product silhouette, cap or hinge, materials and prop positions stable; hold the final hero frame. Exclude: extra people or props, text, logos and watermarks.

Generated with Seedance 2.0

Creative direction: A researcher at a wooden table unrolls an old map, traces a route with one finger, and examines a marked point with a small brass instrument. Alternate between the hands, parchment details, and a measured medium view of the archival workspace. Visual treatment: Live-action archival demonstration with warm parchment, brass and natural skin texture. Shot sequence: 1. Show the researcher unrolling parchment on the wooden table.; 2. Cut closer as one finger follows the route and the brass instrument approaches the marked point.; 3. Return to a measured medium view with the map orientation unchanged. Continuity: Keep demonstration props, layout and hand contact consistent so the action remains legible. Exclude: extra people or props, text, logos and watermarks.

Cut to fingers depressing keys and then operating the sampler.; 3. Return to the profile while the blue-purple practical lights stay steady.
