LosslessCut – 无损视频/音频编辑的瑞士军刀



LosslessCut aims to be the ultimate cross platform FFmpeg GUI for extremely fast and lossless operations on video, audio, subtitle and other related media files. The main feature is lossless trimming and cutting of video and audio files, which is great for saving space by rough-cutting your large video files taken from a video camera, GoPro, drone, etc. It lets you quickly extract the good parts from your videos and discard many gigabytes of data without doing a slow re-encode and thereby losing quality. Or you can add a music or subtitle track to your video without needing to encode. Everything is extremely fast because it does an almost direct data copy, fueled by the awesome FFmpeg which does all the grunt work.

Manual input of cutpoint times
Apply a per-file timecode offset (and auto load timecode from file)
Edit file metadata, per-track metadata and per-track disposition
Change rotation/orientation metadata in videos
View technical data about all tracks
Timeline zoom and frame/keyframe jumping for cutting around keyframes
Video thumbnails and audio waveform
Saves per project cut segments to project file
View FFmpeg last command log so you can modify and re-run recent commands on the command line
Give labels to cut segments
Annotate segments with tags
Import/export segments: MP4/MKV chapter marks, Text file, YouTube, CSV, CUE, XML (DaVinci, Final Cut Pro) and more
MKV/MP4 embedded chapters marks editor

Add music to a video (or replace existing audio track)
Combine audio and video tracks from separate recordings
Include an external subtitle into a video
Quickly change a H264/H265 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 process these in another tool
Quickly cut a file by its MP4/MKV chapters
Quickly cut a YouTube video by its chapters (or music times from a comment)
Change the language of a file’s audio/subtitle tracks
Attach cover art to videos
Change author, title, GPS position, recording time of a video
Fix rotation of a video that has the wrong orientation flag set
Great for rotating phone videos that come out the wrong way without actually re-encoding the video.
