 ### 预览内容导出
 
-支持预览图和视频的导出.
+导出遵循 "所见即所得" 原则, 即实时预览的画面就是你导出的画面.
 
-预览图导出的内容是模型的默认状态画面, 每个模型一张单独的预览图.
+导出有以下几个关键参数:
+
+- 仅渲染选中. 这个参数不仅影响预览模式, 也影响导出, 如果仅渲染选中, 那么在导出时只有被选中的模型会被考虑, 忽略其他模型.
+- 输出文件夹. 这个参数某些时候可选, 当不提供时, 则将输出产物输出到每个模型各自的模型文件夹, 否则输出产物全部输出到提供的输出文件夹.
+- 导出单个. 默认是每个模型独立导出, 即对模型列表进行批量操作, 如果选择仅导出单个, 那么被导出的所有模型将在同一个画面上被渲染, 输出产物只有一份.
+
+支持单帧画面以及不同格式的视频导出.
 
 视频(TODO: 目前仅支持帧序列导出), 可以在每个骨骼的模型参数中查看动画完整时长.
 
-当预览画面处于仅渲染选中状态时, 导出的内容仅包含被选中的模型, 也就是在画面中显示的内容.
-
 ### 格式与版本转换
 
-可以通过工具菜单进行骨骼文件换, 允许二进制和文本格式之间的转换, 以及不同版本间的转换.
+可以通过工具菜单进行骨骼文件转换, 允许二进制和文本格式之间的转换, 以及不同版本间的转换.
 
 目前处于施工中, 仅支持转换 `3.8.x` 二进制到文本格式.
