天台起舞 360°Rooftop Dance她一直在跳，拖动画面转动整个天台She keeps dancing — drag to spin the whole rooftop

做法：背景和人分两层。背景是《朋友圈》第 4 格用 Qwen Image 2.1 去掉人之后的空天台，再用 MiniMax-H3 + ORB360 LoRA 绕一圈（1024×768 · 124 帧 · 20 步）；人是同一张原图当首帧和尾帧，MiniMax-H3 FL2V（8 步 turbo，1536×1152）出一段原地跳舞、首尾相接的 5 秒视频，SAM 3.1 逐帧抠出来叠在中间循环播放，音乐也是 H3 一起生成的。拖动只转背景，所以无论转到哪个角度，她都是正面朝着你。

How it’s made: two layers. The background is panel 4 of The Feed with her removed by Qwen Image 2.1, then orbited by MiniMax-H3 + the ORB360 LoRA (1024×768 · 124 frames · 20 steps). The dancer uses the same picture as both first and last frame: MiniMax-H3 FL2V (8-step turbo, 1536×1152) makes a 5-second dance that loops seamlessly, SAM 3.1 cuts her out frame by frame, and she loops in the middle. The music comes from H3 too. Dragging only spins the background, so she faces you from every angle.
