## What it is
LosslessCut is a cross-platform desktop GUI built on FFmpeg for lossless trimming, cutting, merging, and track editing of video, audio, and subtitle files. It performs near-instant operations by directly copying data streams without re-encoding, preserving original quality.

## Use cases
- trim large GoPro or drone videos without re-encoding
- cut commercials out of recorded TV files losslessly
- merge clips from the same camera into one file
- extract audio or subtitle tracks from a video
- add a music or subtitle track to a video file
- remux a video into a different container format
- take full-resolution screenshots from video

## When to choose
- you need fast cuts without quality loss or re-encoding
- you want a simple GUI instead of hand-writing FFmpeg commands
- you need to extract, combine, or remove individual tracks
- you work with large camera footage and want to save disk space quickly

## When to avoid
- you need transitions, effects, or color grading
- you require frame-accurate cuts at arbitrary points (lossless cuts snap to keyframes)
- you need a full timeline-based video editor
- your files have mismatched codec parameters for merging
