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。

Features

• Losslessly trim or cut out parts of video/audio
• Lossless merge/concatenation of arbitrary files (identical codec parameters)
• Lossless stream editing: Combine arbitrary tracks from multiple files
• Losslessly extract all tracks from a file
• Remux into any compatible output format
• Take full-resolution snapshots from videos in JPEG/PNG format
• Apply a per-file timecode offset in the preview
• Change rotation/orientation metadata in videos
• Powerful timeline with zoom and frame/keyframe jumping
• Auto-saves per project cut segments to file
• View ffmpeg last command log so you can modify and re-run modify recent commands on the command line
• Give labels to cut segments
• Segment panel showing segments with details, export/import cut segments as CSV
• Video thumbnails and audio waveform

Other usage scenarios

• Cut out commercials from a recorded TV show
• Remove audio or video track from a file
• Add music to a video (or replace existing audio track)
• Include a subtitle into a video
• Extract music, video or subtitle track from a video and cut it to your needs
• Change format of a H264 TV recording from TS to MP4
• Fix rotation of a video that has the wrong orientation flag set, e.g. phone recording
• Quickly change a H264 MKV video to MOV or MP4 for playback on iPhone
• Import a list of cut times from other tool as a EDL (edit decision list, CSV) and run these cuts with LosslessCut
• Export a list of cut times as a CSV EDL and run these in another tool
• Loop a video / audio clip X times quickly without re-encoding

* 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.

特征

• 无损修剪或剪切部分视频/音频
• 任意文件的无损合并/串联（相同的编解码器参数）
• 无损流编辑：合并来自多个文件的任意曲目
• 无损地从文件中提取所有曲目
• 将 Remux 转换为任何兼容的输出格式
• 从 JPEG/PNG 格式的视频中拍摄全分辨率快照
• 在预览中应用每个文件的时间码偏移量
• 更改视频中的旋转/方向元数据
• 具有缩放和帧/关键帧跳跃功能的强大时间轴
• 自动将每个项目将段剪切到文件
• 查看 ffmpeg 上一个命令日志，以便您可以在命令行上修改并重新运行 modify recent 命令
• 为剪切段提供标签
• 显示带有详细信息的线段的线段面板，将剪切线段导出/导入为 CSV
• 视频缩略图和音频波形

其他使用场景

• 从录制的电视节目中剪掉广告
• 从文件中删除音频或视频轨道
• 向视频添加音乐（或替换现有音轨）
• 在视频中加入字幕
• 从视频中提取音乐、视频或字幕轨道，并根据需要进行剪切
• 将 H264 电视录制的格式从 TS 更改为 MP4
• 修正视频的旋转设置了错误的方向标志，例如电话录制
• 快速将 H264 MKV 视频更改为 MOV 或 MP4 以便在 iPhone 上播放
• 将切割时间列表从其他工具导入为 EDL（编辑决策列表，CSV），并使用 LosslessCut 运行这些切割
• 将切割时间列表导出为 CSV EDL，并在其他工具中运行这些时间
• 快速循环播放视频/音频剪辑 X 次，无需重新编码

* 哪个功能可用取决于所讨论的文件以及此文件具有
的格式/编解码器 * 此应用程序不适用于精确剪切。开始剪切时间将“四舍五入”到最接近的上一个关键帧，该关键帧可能比所需的剪切点早几分之一秒，也可能长达几秒钟，具体取决于编码。
