Seedance 2.5

Seedance 2.5-Modelle werden über eine einheitliche, asynchrone Job-API aufgerufen. Starte einen Task mit POST /api/generate und frage dann GET /api/generate/{taskId} ab, bis er fertig ist. Diese Familie stellt 10 Endpunkte bereit.

Überblick

Jeder Endpunkt teilt sich dieselbe Hülle — nur model und die input-Felder ändern sich. Führe einen beliebigen im Playground des Modell-Markts aus.

Seedance 2.5 image-to-video modes

Three mutually exclusive modes — match fields to the model slug:

  • image-to-video: first_frame_url only; aspect_ratio must be adaptive; set first_frame_portrait_kind: skip for scenes.
  • first-last-frame: first_frame_url + last_frame_url; also requires adaptive.
  • omni-reference: reference_image_urls plus optional video/audio; mark portraits virtual/real, backgrounds skip; fixed ratios like 16:9 work.

On direct routes, only portraits are ingested to the portrait library; scenes, video, and audio stay as direct URLs. Copy the full API doc from the model API tab.

Portrait reference details
On direct routes, only portrait images are uploaded to the portrait library; scenes, videos, and audio stay as direct public URLs. Pair reference_image_urls with reference_portrait_kinds per slot:virtual (portrait library — real or AI; real is equivalent), skip (background/scene — default when omitted). Single-frame and first/last-frame models use first_frame_url / last_frame_url (ingested by default); set first_frame_portrait_kind to skip to keep a direct URL.

Seedance 2 Referenzmedien-Limits

Diese Werte sind öffentlich dokumentierte Validierungsregeln der derzeit an 97AI.PRO angebundenen Upstream-Schnittstelle. Sie sind keine dauerhaften offiziellen Modelllimits. Bereiche können je nach Route abweichen; maßgeblich ist die API-Antwort.
