本数据集仅包含1949年南加州大学出品的医学胶片《The thinnest slice》（暂译《最薄切片》）的未标注剪辑片段与裁切段，总时长7分钟；该片由Daniel H. Chapman撰写脚本并制作，George Pratt担任导演。1949年摄制的切片机（microtome）样本制备与切片操作片段：将未标识样本的一部分浸入溶液，放置于小型载块并完成硬化处理；随后将该载块安装于切片机，将样本切割至足以在显微镜下观测的薄度。胶片打板（film slates）标注信息如下：署名Chapman；项目编号P114；胶片卷号346、348、395。在该切片机摄制片段的中段，插入了一段时长极短、与主题无关的野外考察人员影像。容器标注为“未标注剪辑片段与裁切段”；该片段帧率为18帧/秒，胶片长度189英尺，采用双齿孔片基，乳剂面朝外，为黑白正片，无同步录音（MOS）。
