ComfyUI 原生 Kling Camera Controls 节点 Kling Camera Controls 节点用于定义虚拟摄像机的行为参数，控制Kling视频生成过程中的镜头运动和视角变化。

​
参数说明

参数类型默认值说明
camera_control_type选择项”simple”预定义的摄像机运动类型。simple: 可自定义的摄像机运动；down_back: 摄像机下降并向后移动；forward_up: 摄像机向前移动并向上倾斜；right_turn_forward: 向右旋转并向前移动；left_turn_forward: 向左旋转并向前移动
horizontal_movement浮点数0控制摄像机沿水平轴（x轴）的移动。负值表示向左，正值表示向右
vertical_movement浮点数0控制摄像机沿垂直轴（y轴）的移动。负值表示向下，正值表示向上
pan浮点数0.5控制摄像机在垂直平面上的旋转（x轴）。负值表示向下旋转，正值表示向上旋转
tilt浮点数0控制摄像机在水平平面上的旋转（y轴）。负值表示向左旋转，正值表示向右旋转
roll浮点数0控制摄像机的滚动量（z轴）。负值表示逆时针，正值表示顺时针
zoom浮点数0控制摄像机焦距的变化。负值表示视场变窄，正值表示视场变宽
注意：至少需要一个非零值的摄像机控制参数才有效。

输出

输出类型说明
camera_controlCAMERA_CONTROL包含摄像机设置的配置对象
注意：并非所有模型和模式组合都支持摄像机控制。请参考Kling API文档了解更多信息。
