LosslessCut – swiss army knife of lossless video/audio editing

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 useful for saving space by rough-cutting large video files taken from a video camera, GoPro, drone, etc.

This is free and open source software.

Features include:

• Lossless cutting of most video and audio formats.
• Smart cut (experimental).
• Losslessly cut out parts of video/audio (for cutting away commercials etc.).
• Losslessly rearrange the order of video/audio segments.
• Lossless merge/concatenation of arbitrary files (with identical codecs parameters, e.g. from the same camera).
• Lossless stream editing:
  • Combine arbitrary tracks from multiple files (ex. add music or subtitle track to a video file).
  • Remove unneeded tracks.
  • Replace or re-encode only some tracks.
  • Extract all tracks from a file (extract video, audio, subtitle, attachments and other tracks from one file into separate files).
• Fast multi-file workflow (note: no mass/batch export yet).
• Keyboard shortcut workflow.
• Losslessly remux video/audio into a different container (file) format.
• Take full-resolution snapshots from videos in JPEG/PNG format (low or high quality).
• Export ranges of video frames to images (every nth frame, second, by scene change, best thumbnails):
  • Export only from a selected time range (segment).
  • Optionally include original timestamps in image file names.
• 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.
• Undo/redo.
• 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.
• View subtitles.
• Customizable keyboard hotkeys.
• Black scene detection, silent audio detection, and scene change detection.
• Divide timeline into segments with length L or into N segments or even randomized segments!
• Speed up / slow down video or audio file (changing FPS).
• Basic CLI and HTTP API (experimental).
• Cross-platform support – runs under Linux, macOS, and Windows.
