LosslessCut is the Swiss army knife of lossless video/audio editing

Software Santa adopted it a week ago - it does ALL of the 'Grunt Work' now!!!!
* Please note: - LosslessCut is not a tool for exact cutting. Start cut time will be "rounded" to the nearest previous keyframe, which may be up to several seconds before your desired cut point, depending on the video encoding.
- Although LosslessCut can open almost any audio/video format, there are some that can not be cut. There are some known issues with cutting videos from the newest iPhones.
Therefore: it may not be right for your uses.

LosslessCut

The swiss army knife of lossless video/audio editing
Shave gigabytes off video and audio files in seconds without loss of quality


Traditional video editors
Any operation in a normal video editor requires you to re-encode the whole file which can take hours and you will gradually lose quality every time you cut.

LosslessCut
LosslessCut will do the same in seconds without losing quality:
LosslessCut simply cuts the data stream and directly copies it over.

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.

Features

    Lossless cutting of most video and audio formats
    Losslessly cut out parts of video/audio (for cutting away commercials etc.)
    Lossless merge/concatenation of arbitrary files (with identical codecs parameters, e.g. from same camera)
    Lossless stream editing: Combine arbitrary tracks from multiple files (ex. add music or subtitle track to a video file)
    Losslessly extract all tracks from a file (extract video, audio, subtitle and other tracks from one file into separate files)
    Remux into any compatible output format
    Take full-resolution snapshots from videos in JPEG/PNG format
    Manual input of cutpoint times
    Apply a per-file timecode offset
    Change rotation/orientation metadata in videos
    View technical data about all streams
    Timeline zoom and frame/keyframe jumping for accurate cutting around keyframes
    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
    Undo/redo
    Give labels to cut segments
    View segment details, export/import cut segments as CSV
    Video thumbnails and audio waveform

Example lossless use cases

Remove audio tracks from a file
Add music to a video (or replace existing audio track)
Link audio and video tracks from separate recordings
Include a subtitle into a video
Extract music track from a video and cut it to your needs
Cut out commercials from a recorded TV show  - Without having to re-encode. You can also change format from TS to MP4 at the same time.
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.
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


Advanced multi-step workflows

Tip: you can use LosslessCut in multiple passes in order to achieve separate trimming of individual tracks:

    Open a file an export all tracks
    Open the exported track files independently and cut them as desired
    Add the track back to the video and combine them to one output video

Download

If you want to support the continued work on LosslessCut, and want the advantage of a secure and simple installation process with automatic updates, consider getting it from your favorite APP store


If you prefer to download the executables manually, this will of course always be free:

    Mac OS X
    Windows
    Linux tar.bz2
    More releases

If you find LosslessCut useful, I'm very thankful for donations.


Supported formats

Since LosslessCut is based on Chromium and uses the HTML5 video player, not all ffmpeg supported formats will be supported smoothly. The following formats/codecs should generally work: MP4, MOV, WebM, MKV, OGG, WAV, MP3, AAC, H264, Theora, VP8, VP9 For more information about supported formats / codecs, see https://www.chromium.org/audio-video.

Unsupported files can still be converted to a supported format/codec from the File menu. (Try fastest variant first.) A low quality version of the file (without audio) will then be created and opened in the player. The cut/export operation will still be performed on the original file, so it will be lossless. This allows for potentially opening any file that ffmpeg is able to decode.
