What it does

LosslessCut trims, cuts, joins and rearranges video and audio files. It puts a window with buttons in front of FFmpeg, the command-line program most video tools use underneath, and FFmpeg does the work. It copies the picture and sound already in the file instead of encoding them again, so a save takes seconds. It can change the container, which is the wrapper around the picture and sound, without touching the content inside. It opens files with several video, audio and subtitle tracks and can save one track on its own. It can edit titles and rotation, take still pictures, export single frames, and import or export lists of segments. It does not re-encode video to shrink or improve it, it has no batch export yet, and some formats will not play natively, so a low-quality preview copy is made while the cut still runs on the original.

Why it matters

Who it suits. It fits people who record long and publish short: cutting dead time off the front, splitting a two-hour recording into parts, joining takes, or lifting the sound out of a video. It also fits anyone working through very large camera files on a modest computer, because nothing is encoded a second time. Skip it when the job needs titles, transitions, colour work or several layers on top of each other. That is a full editor's work, and this program does not claim to do it.

Verdict. Worth an hour, and worth keeping after that. There is nothing to compile, and the first useful cut takes about ten minutes to learn. The thing to watch is where a cut lands. Cuts happen at the join points already inside the file, so the result can sit a fraction of a second away from the mark. For edits led by speech that is sometimes too rough, and a tool that removes silence by itself is a better first pass. Keep a full editor alongside for titles and effects, and use this one for the rough cut that comes first.

Summary (Key Points)from the README
Key features
  • Lossless cutting: Trims and cuts video and audio losslessly, using an almost direct data copy through FFmpeg, so no re-encode is needed.
  • Space saving: Rough-cuts large camera, GoPro or drone files by discarding unwanted gigabytes without quality loss.
  • Merging: Joins cut segments, or whole files with identical codecs, losslessly.
  • Track handling: Adds, removes, replaces or extracts audio, subtitle and other tracks.
  • Remuxing: Changes container format, for example MKV to MP4, without re-encoding.
  • Markers and chapters: Manages segments, markers and tags, with import and export of chapters, CSV, EDL and more.
  • Detection and splitting: Detects scenes, black frames and silence, and splits files by them.
  • Metadata and export: Edits metadata and rotation, exports snapshots and frames, and offers keyboard shortcuts, a CLI and an HTTP API.

Important
  • Playback limits: Playback uses the Chromium HTML5 player, so not all codecs play natively; other files play through FFmpeg-assisted playback or can be converted via File → Convert to supported format.
  • Lossless export: Even converted files are exported from the original, so output stays lossless.
  • Platform gaps: APPX (Windows) and PKG (macOS) do not work, and Windows 7, 8 and 8.1 are no longer supported after v3.50.0.
  • Raspberry Pi caveat: The armv7l build does not include FFmpeg.
  • Unofficial builds: Flathub and other unofficial releases are not maintained by the author; the listed official downloads are the only ones the author provides.
  • Single maintainer: The project is maintained by one person alone, so support and updates depend on that individual.

Written by an AI model from the project’s README; not part of the review, and it can be wrong.

Good
  • A save takes seconds instead of hours, and the picture is exactly what came out of the camera.
  • It is a window with buttons. Nothing here needs the command line.
  • Ready-made downloads for macOS on both chip types, Windows, Linux, and Raspberry Pi.
Watch for
  • A cut lands on a join point already inside the file, so it can sit a fraction of a second from the mark. That is the price of not building the file again.
  • The licence is GPL-2.0. Using the program is free. Putting its code inside a product that is sold is not practical.
  • Playback uses the browser engine inside the program, so some formats only preview at low quality. The Windows APPX and macOS PKG packages do not work at all.
