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

LosslessCut uses Chromium's HTML5 video player, and not all FFmpeg supported formats and codecs are natively supported. Generally, the following formats should work: `MP4`, `MOV`, `WebM`, `Matroska`, `OGG` and `WAV`. The following audio codecs: `FLAC`, `MP3`, `Opus`, `PCM`, `Vorbis` and `AAC`. Video codecs: `H264`, `AV1`, `Theora`, `VP8`, `VP9` and `H265` (needs hardware decoder). More information about [Chromium supported formats / codecs](https://www.chromium.org/audio-video). [What's the difference between a codec and a format?](./issues.md#primer-video--audio-formats-vs-codecs)
Codecs and formats not listed above can still be converted to a supported format/codec from the `File` menu. (Try the `fastest` option first.) A low quality version of the file (with/without audio) will then be created and opened in the player. 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.
