Competitor Comparisons
Video Editor for Linux
Pros of Flowblade
- Full-featured non-linear video editor with a comprehensive set of tools
- Supports complex multi-track editing and compositing
- Offers a wide range of video and audio effects
Cons of Flowblade
- Steeper learning curve due to its more complex interface
- Requires more system resources for processing and rendering
- Limited to Linux operating systems
Code Comparison
Flowblade (Python):
def _get_track_counts():
audio_tracks = get_track_count()
video_tracks = PROJECT().get_track_count() - audio_tracks
return (video_tracks, audio_tracks)
LosslessCut (JavaScript):
function getFrameCount({ frames, fps, duration }) {
if (frames) return frames;
if (fps && duration) return Math.round(fps * duration);
return undefined;
}
Summary
Flowblade is a comprehensive video editing software for Linux, offering advanced features and multi-track editing capabilities. It's suitable for more complex projects but requires a steeper learning curve. LosslessCut, on the other hand, is a simpler, cross-platform tool focused on quick and lossless cutting of video files. While Flowblade provides more editing power, LosslessCut offers ease of use and faster processing for basic cutting tasks.
Free open-source non-linear video editor
Pros of Olive
- Full-featured non-linear video editor with a timeline, effects, and transitions
- Supports a wide range of video formats and codecs
- Offers a more comprehensive set of editing tools for complex projects
Cons of Olive
- Steeper learning curve due to its more complex interface and features
- Larger file size and potentially higher system requirements
- May be overkill for simple trimming and cutting tasks
Code Comparison
Olive (C++):
void Clip::set_timeline_in(const rational &r)
{
timeline_in_ = r;
InvalidateVisible();

LosslessCut (JavaScript):
function cutSegment(filePath, cutFrom, cutTo) {
const ffmpegArgs = ['-i', filePath, '-ss', cutFrom, '-to', cutTo, '-c', 'copy'];
return runFfmpeg(ffmpegArgs);
}
While both projects deal with video editing, their codebases reflect their different approaches. Olive's C++ code handles complex timeline operations, while LosslessCut's JavaScript focuses on simple cutting tasks using FFmpeg.

const cuts = cutTimes.map(({ start, end }) => ({
from: start,
to: end,
}));
return cut({ cutFrom: cuts[0].from, cutTo: cuts[cuts.length - 1].to, cuts });
}
OpenShot offers a more comprehensive video editing solution with a graphical interface, while LosslessCut focuses on quick, lossless cutting of video files. OpenShot's code demonstrates its integration with a timeline and viewport, reflecting its full-featured nature.

Code Comparison
Kdenlive (C++):
void TimelineModel::requestItemResize(int itemId, int size, bool right)
{
QWriteLocker locker(&m_lock);
std::shared_ptr<AbstractClipItem> item = getItemById(itemId);
if (item) {

Pros of NewPipe
- Offers a wide range of features for YouTube streaming and downloading
- Provides an ad-free experience with background playback
- Supports multiple video platforms beyond YouTube
Cons of NewPipe
- Limited to Android devices, not available for desktop or iOS
- Requires manual updates and installation outside of the Google Play Store
- May have compatibility issues with certain YouTube features
Code Comparison
NewPipe (Java):
@Override
protected void onLoadFinished() {
if (currentInfo == null) {
return;
}
super.onLoadFinished();
}
LosslessCut (JavaScript):
async function cutMultiple(cutTimes) {
const cuts = await Promise.all(cutTimes.map(({ start, end }) => (
cut({ start, end })
)));
return cuts;
}
While both projects are open-source and focus on video-related functionality, they serve different purposes. NewPipe is a feature-rich YouTube client for Android, while LosslessCut is a cross-platform video trimming tool. NewPipe's codebase is primarily in Java, tailored for Android development, whereas LosslessCut uses JavaScript with Electron for desktop applications. NewPipe offers a more comprehensive set of features for video streaming and downloading, but LosslessCut provides specialized functionality for lossless video cutting across multiple platforms.

LosslessCut
The swiss army knife of lossless video/audio editingThanks to my supporters and everyone who purchased LosslessCut!
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. There are also many more use cases. Everything is extremely fast because it does an almost direct data copy, fueled by the awesome FFmpeg which does all the grunt work.

- Extract music track from a video and cut it to your needs
- 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

- Losslessly split a video into one file per scene (note you probably have to shift segments, see #330.)
- Cut away silent parts of an audio/video
- Split video into segments to for example respect Twitter's 140 second limit
- Annotate each segment with one or more tags, then use those tags to organize your segments or use it to create an output folder structure or hierarchy for your segments.
Export cut times as YouTube Chapters
- Export with Merge and "Create chapters from merged segments" enabled
- Open the exported file and select "Import chapters" in the dialog
- File -> Export project -> YouTube Chapters
Re-encode only the audio track, keeping the lossless video track
First export each track as individual files. Then use Handbrake or similar to re-encode the audio file (if mp4 file, encode as AAC.) Then open the extracted video stream in LosslessCut. The open your encoded audio file and select "Include all tracks from the new file". Then export.
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 as individual files
- 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 my continued work on LosslessCut, and you want the advantage of a secure and simple installation process with automatic, stable updates, consider getting it from your favorite store:
For Linux these are some alternatives:
If you prefer to download the executables manually, this will of course always be free (see also supported operating systems):
- macOS: Intel / Apple Silicon DMG (note that PKG does not work)
- Windows: 7zip (Windows 7, 8 and 8.1 is no longer supported after v3.50.0)
- Linux: x64 tar.bz2 / x64 AppImage / arm64 tar.bz2 / Raspberry Pi armv7l
- More releases - Note that APPX (Windows) and PKG (macOS) do not work)
- Latest nightly builds ð§ª
Difference between App Stores and GitHub download? Please see FAQ.
LosslessCut is maintained by me alone and will always remain free and open source. If it's useful to you, consider supporting my work. Alternatively donate to FFmpeg because they are doing the world a huge favor.
Supported formats
LosslessCut uses the Chromium browser's HTML5 video player, and not all formats/codecs are natively supported. Generally, the following file formats work: MP4
, MOV
, WebM
, Matroska
, OGG
and WAV
. Audio codecs: FLAC
, MP3
, Opus
, PCM
, Vorbis
and AAC
. Video codecs: H264
, AV1
, Theora
, VP8
, VP9
and H265
(with hardware decoder). Learn the difference between a codec and a format. Codecs and formats not listed above can still be converted to a supported format/codec from the File
menu (try the option Fastest: FFmpeg-assisted playback first). A low quality version of the file will then be created and opened in the player. Note that the actual 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.
