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-pro video generation prompt examples

Start with a seedance-2.0-pro 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 anime courier in an orange coat and backpack runs through a rain-lit city after a floating white envelope. The camera tracks the chase past blue and red reflections until the courier reaches out and catches the envelope, followed by a brief sketch-like echo. Visual treatment: Anime action with blue-red wet reflections and a brief drawn motion echo. Shot sequence: 1. Track the orange-coated courier chasing the white envelope.; 2. Keep the reaching hand and envelope together through the rain-lit chase.; 3. Show the catch clearly, then let the brief sketch echo fade. 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.

The camera widens as clouds separate around a bright shape in the sky, keeping the small figure and luminous object in the same frame. Visual treatment: Stylized animated rooftop fantasy with cool moonlight and a warm luminous prop. Shot sequence: 1. Frame the caped figure and glowing orb on the rooftop.; 2. Widen as the figure lowers the orb near the vents.; 3. Reveal the bright sky shape through separating clouds with the figure still in frame. Continuity: Maintain scene geography, subject scale and motivated light direction throughout the camera move. Exclude: extra people or props, text, logos and watermarks.

Unfold the orange cube into the hovering robot above the open hand.; 3. Let the robot complete one small circle and settle beside the shoulder. Continuity: Maintain character design, equipment geometry and travel direction from first to final frame. Exclude: extra people or props, text, logos and watermarks.

Ignite the red-orange baton and follow one broad arm swing.; 3. Hold the finished light curve against the skyline as the arm settles.
