LosslessCut – Super Fast Tool for Trimming / Cutting Video & Audio

Last updated: April 24, 2024

No patience with common video editors (e.g., Kdenlive and Openshot) as they can take hours to export a video after trimming / cutting it? Try LosslessCut.

LosslessCut is a cross platform tool for lossless trimming / cutting of video and audio files. The software is extremely fast, it does the job in seconds without losing quality because it simply cuts the data stream and directly copies it over.

With LosslessCut, you can do:

  • 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
  • Cut out commercials from a recorded TV show
  • Replace audio track
  • Include a subtitle into a video
  • Extract audio, video, oro subtitle track from video

How to Get LosslessCut in Ubuntu:

There’s no .deb binary package for the software so far. You can either download the appimage or Linux tarball from the link below:

You can choose:

  • grab the .appimage package, give executable permission in file Properties, finally run it to launch the software.
  • or download the Linux tarball, extract and run the executable file to open the video editor.

Launch Lossless Cut executable from portable Linux tarball

The software is also available in Ubuntu Software as Snap package. The package version is however lag behind.

For those OK with Linux universal Flatpak package, LosslessCut can be also installed via the flathub repository.

  1. Someone can help me to compile in linux from source?

    git clone https://github.com/mifi/lossless-cut.git
    cd lossless-cut

    then run
    npm start
    but not start well…start with errors

    Help, please

  2. Once again an AppImage method is useless and non user friendly from the get go:

    sudo chmod a+x LosslessCut-linux.AppImage
    [sudo] password for tux:

    ~/Downloads ❯❯❯ ./LosslessCut-linux.AppImage
    [21803:0328/115134.586394:FATAL:setuid_sandbox_host.cc(157)] The SUID sandbox helper binary was found, but is not configured correctly. Rather than run without sandboxing I’m aborting now. You need to make sure that /tmp/.mount_Lossle8FT943/chrome-sandbox is owned by root and has mode 4755.
    [1] 21803 trace trap ./LosslessCut-linux.AppImage

    -and i can’t use the snap package on this system. It is 64 bit Debian-based system. What to do?

  3. Don’t want to sound dumber than i have to, but… This seems to be a sweet little app that has everything going for it but help/documentation.
    All i’m asking for is a simple ReadMe- a few paragraphs of “to make simple cuts, do this and then this and then that..”. Without such all that coding work goes to waste…
    Is everybody in the world psychic but me?

    • I’m finding the user interface to be a complete mystery as well.

      That often means it closely resembles some other program that is popular and well-understood, so documentation is superfluous, except for people like us who never heard of that program.
