wan2.7-r2v API

透過 Modelflare 非同步視訊路由使用準確的 wan2.7-r2v 模型 ID。

使用準確的型號 ID wan2.7-r2v。模型欄位必須與此頁面完全相符。

範例輸出wan2.7-r2vPOST /v1/videos5.0s

參數: duration=5resolution=1080Pratio=16:9參考圖片

提示詞: One continuous take, no cuts. Keep the glass flowers from the reference exactly as they are and carry them into a new place: a wide city crossing at night in the rain. The whole bed of glass blooms now grows straight out of the wet asphalt across the junction, ringing as the rain strikes them, headlights firing caustics along the road. The camera starts at kerb height among the stems, moves forward through them and rises to look down the length of the crossing. One hard pink key from a shopfront on the left, cold blue signals behind. Real weight and inertia, glass and water, no text.

萬常用input和parameters;幀引導模式和參考媒體模式不得混合。

Wan2.7 R2V 使用 reference_image / reference_video 介質,並且可以附加 reference_voice。請勿將此工作流程與 first_frame / last_frame 角色混合。
