The Swiss Army Knife of Lossless Video/Audio Editing

losslesscut

Shave gigabytes off video and audio files in seconds without loss of quality

LosslessCut 旨在成为最终的跨平台 FFmpeg GUI，用于对视频、音频、字幕和其他相关媒体文件进行极其快速和无损的操作。

其主要功能是对视频和音频文件进行无损修剪和切割，这对于通过粗略切割从摄像机、GoPro、无人机等拍摄的大型视频文件来节省空间是很好的。它可以让你快速地从视频中提取好的部分，丢弃许多千兆字节的数据，而不做缓慢的重新编码，从而失去质量。或者你可以为你的视频添加音乐或字幕轨，而不需要编码。一切都非常快，因为它几乎是直接进行数据复制，由令人敬畏的 FFmpeg 来完成所有粗重的工作。

* Which function is available depends on the file in question and which format/codec this file has
* This app is not for exact cutting. Start cut time will be “rounded” to the nearest previous keyframe, which may be a fraction of a second before your desired cut point, or up to several seconds, depending on the encoding.
