视频去重工具Video Deduplication

本套视频去重软件，是早期针对义乌视频带货场景开发的工具。软件主要用于解决短视频发布中出现的内容不适宜、无法加热等问题，实现一份素材在无限个账号上进行无限分发。This set of video deduplication software was an early tool developed for the Yiwu video e-commerce scenario. The software is mainly used to solve problems such as inappropriate content or inability to boost in short video publishing, enabling a single piece of material to be distributed infinitely across unlimited accounts.

软件包含一项名为幽灵时长的元数据篡改技术：视频本体实际时长为30秒，但修改文件元数据后上传时会显示为一小时；上传完成后实际播放依旧是原本30秒内容，仅文件层面篡改时长信息，即幽灵时长效果。The software includes a metadata tampering technique called 'ghost duration': the actual length of the video is 30 seconds, but after modifying the file metadata, it will show as one hour when uploaded; after the upload is complete, the actual playback remains the original 30 seconds content, only the duration information at the file level is tampered with, which is the ghost duration effect.

整套工具底层集成多类去重处理手段，分为元数据层、画面像素层、时序帧处理层、音频轨道层，完整技术清单如下：The entire toolset integrates multiple deduplication methods at the underlying level, divided into metadata layer, image pixel layer, temporal frame processing layer, and audio track layer. The complete technical list is as follows:

该项目最早开源发布于GitHub，项目名称为去重高手、去重大师。目前市面上便捷点、筷子、超级编导等多款工具，底层技术底座均来源于该开源项目。This project was first open-sourced on GitHub, with the project names 'Duplicate Removal Expert' and 'Duplicate Master'. Currently, many tools on the market such as Bianjian Dian, Kuai Zi, and Super Director all have their underlying technology foundation sourced from this open-source project.
