3. 系统功能流程图

以下是用户从上传文件到生成视频的核心流程“bd-box<h-char class=“bd bd-beg“>“><h-char class=“bd bd-beg“>：

上传照片与视频
- 用户通过前端界面上传照片和视频片段“bd-box<h-char class=“bd bd-beg“>“><h-char class=“bd bd-beg“>，支持拖拽上传“bd-box<h-char class=“bd bd-beg“>“><h-char class=“bd bd-beg“>。
- 后端接收文件并存储“bd-box<h-char class=“bd bd-beg“>“><h-char class=“bd bd-beg“>，同时解析文件以便后续处理“bd-box<h-char class=“bd bd-beg“>“><h-char class=“bd bd-beg“>。
时间轴编辑与参数设置
- 用户在前端调整照片与视频的顺序“bd-box<h-char class=“bd bd-beg“>“><h-char class=“bd bd-beg“>，并设置时间长度与转场效果“bd-box<h-char class=“bd bd-beg“>“><h-char class=“bd bd-beg“>。
- 最终生成一个配置文件“bd-box<h-char class=“bd bd-beg“>“>（JSON“bd-box<h-char class=“bd bd-beg“>“><h-char class=“bd bd-beg“>）<h-char class=“bd bd-beg“>，传递到后端“bd-box<h-char class=“bd bd-beg“>“><h-char class=“bd bd-beg“>。
视频拼接与转场处理
- 后端通过 FFmpeg 根据用户配置“bd-box<h-char class=“bd bd-beg“>“><h-char class=“bd bd-beg“>，完成照片与视频的拼接与转场特效处理“bd-box<h-char class=“bd bd-beg“>“><h-char class=“bd bd-beg“>。
- 如果用户添加了背景音乐“bd-box<h-char class=“bd bd-beg“>“><h-char class=“bd bd-beg“>，系统会自动调整音乐长度“bd-box<h-char class=“bd bd-beg“>“><h-char class=“bd bd-beg“>。
实时预览与导出
- 前端调用后端生成的实时预览片段“bd-box<h-char class=“bd bd-beg“>“><h-char class=“bd bd-beg“>，用户确认无误后“bd-box<h-char class=“bd bd-beg“>“><h-char class=“bd bd-beg“>，生成最终视频文件“bd-box<h-char class=“bd bd-beg“>“><h-char class=“bd bd-beg“>。
- 用户可选择下载视频或直接分享至社交媒体“bd-box<h-char class=“bd bd-beg“>“><h-char class=“bd bd-beg“>。
