# LosslessCut 🎥 [![Travis](https://img.shields.io/travis/mifi/lossless-cut.svg)]() Simple, cross platform video editor for lossless trimming / cutting of videos. Great for rough processing of large video files taken from a video camera, GoPro, drone, etc. Lets you quickly extract the good parts from your videos and discard GB of data without losing quality. It doesn't do any decoding / encoding and is therefore extremely fast. Also allows for taking JPEG snapshots of the video at the selected time. This app uses the awesome ffmpeg🙏 for doing the grunt work. Also supports lossless cutting in the most common audio formats. ffmpeg is now included in the app! 🎉 ![Demo](https://thumbs.gfycat.com/HighAcclaimedAnaconda-size_restricted.gif) ## Installing / running - Download [latest LosslessCut from releases](https://github.com/mifi/lossless-cut/releases) - Run LosslessCut app/exe ## Documentation ### Supported platforms - Mac OS X - Windows (64/32bit) - Linux (64/32bit, not tested) ### Supported formats Since LosslessCut is based on Chromium and uses the HTML5 video player, not all ffmpeg supported formats will be supported. The following formats/codecs should generally work: MP4, MOV, WebM, MKV, OGG, WAV, MP3, AAC, H264, Theora, VP8, VP9 For more information about supported formats / codecs, see https://www.chromium.org/audio-video. ### Typical flow - Drag drop a video file into player to load or use ⌘/CTRL+O. - Press SPACE to play/pause - Select the cut start and end time - Press the scissors button to export the slice - Press the camera button to take a snapshot The original video files will not be modified. Instead it creates a lossless export in the same directory as the original file with from/to timestamps. Note that the cut is currently not precise around the cutpoints, so video before/after the nearest keyframe will be lost. EXIF data is preserved. ### Keyboard shortcuts - SPACE, k Play/pause - j Slow down video - l Speed up video - ← Seek backward 1 sec - → Seek forward 1 sec - . (period) Tiny seek forward - , (comma) Tiny seek backward - i Mark in / cut start point - o Mark out / cut end point - e Export selection (in the same dir as the video) - c Capture snapshot (in the same dir as the video) ## Development building / running This app is built using Electron. Make sure you have at least node v4 with npm 3. The app uses ffmpeg from PATH when developing. ``` git clone https://github.com/mifi/lossless-cut.git cd lossless-cut npm install ``` ### Running In one terminal: ``` npm run watch ``` Then: ``` npm start ``` ### Building package ``` npm run download-ffmpeg npm run extract-ffmpeg npm run build npm run icon-gen npm run package # builds all platforms ``` ## Credits - App icon made by [Dimi Kazak](http://www.flaticon.com/authors/dimi-kazak "Dimi Kazak") from [www.flaticon.com](http://www.flaticon.com "Flaticon") is licensed by [CC 3.0 BY](http://creativecommons.org/licenses/by/3.0/ "Creative Commons BY 3.0")
