舞镜 DanceMirror 是为舞蹈学习者、老师和编舞复盘设计的本地视频练习工具。把相册里的示范、课程和自己的练习视频整理到一个 App 里,慢放、镜像、循环、对比和拍摄都围绕“看清动作、练准节奏”设计。 你可以用舞镜: • 按课程、舞种或训练计划创建分组,批量导入本地视频 • 从系统分享菜单快速加入视频,App 内改名、移动和备注不会改动相册原文件 • 在播放器中使用水平镜像、0.1x~2.0x 变速、双指缩放、进度拖动和前后 5 秒跳转 • 设置 A/B 片段循环,长按添加逐帧标记,用备注记录动作重点 • 识别 BPM 并用节拍提示辅助卡点 • 选择两段视频做对比,自动识别相同音轨片段并同步裁剪 • 在对比编辑中调整左右/上下布局、9:16/16:9/1:1/4:5 比例、单独镜像、画面位置、缩放和音量 • 使用人物跟随锁定多人视频中的指定舞者,专注观察主角动作 • 边看示范视频边打开相机录制自己的练习,录制结果保存到本地相册 • 将对比成片导出到相册或文件,便于复盘和分享 隐私与安全: DanceMirror 不需要账号、订阅或登录。导入视频、练习记录、节拍分析、音轨对齐、人物识别/跟随和拍摄内容默认都在本机处理和保存。删除 App 内条目或项目不会删除相册中的原视频。
