wan2.7-i2v API
透過 Modelflare 非同步視訊路由使用準確的 wan2.7-i2v 模型 ID。
使用準確的型號 ID wan2.7-i2v。模型欄位必須與此頁面完全相符。
參數: duration=5resolution=1080pratio=16:9輸入影像
提示詞: One continuous take, no cuts. The ribbon of film keeps unwinding and speeds up until every frame is lit, tightening into a neon helix that lifts off the deck and climbs past the parapet into the dusk sky, the woman in the cobalt coat turning to follow it up. The camera starts low behind her, is pushed back as the helix rises, then cranes up over the parapet and looks along the coil toward the city. One hard magenta key stays raking across the deck. Real weight and inertia, paper and emulsion catching the light, no text.
