 # 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. It doesn't do any decoding / encoding and is therefore extremely fast and has no quality loss. Also allows for taking JPEG snapshots of the video at the selected time. This app uses the awesome ffmpeg🙏 for doing the grunt work. ffmpeg is not included and must be installed separately. Also supports lossless cutting in the most common audio formats.

 ## Installing / running
 
-- Install [ffmpeg](https://www.ffmpeg.org/download.html)
 - Download [latest LosslessCut from releases](https://github.com/mifi/lossless-cut/releases)
-- Run app
+- Run LosslessCut app/exe
-- If ffmpeg is available in <b>$PATH</b>/<b>%PATH%</b> it will just work  
-- If not, a dialog will pop up to select ffmpeg executable path.
 
 ## Documentation
 
+### Typical flow
 - Drag drop a video file into player to load or use <kbd>⌘</kbd>/<kbd>CTRL</kbd>+<kbd>O</kbd>.
-- Select the start and end time
+- Press <kbd>SPACE</kbd> to play/pause
-- Press the scissors button to export a slice.
+- Select the cut start and end time
-- Press the camera button to take a snapshot.
+- 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.

+- With the GOP structure of h.264 you could run into some pretty nasty playback issues without re-encoding if you cut the wrong frames out.
+- Shortcut Cmd+o also triggers o (cut end)
+- implement electron app event "open-file"
+- Travis github deploys https://docs.travis-ci.com/user/deployment
+- react video ref="video" this.refs.video.play()
+- A dedicated "Options" menu where the users can set a default output folder for captured frames and for cut videos will also be handy, now lossless-cut uses the input folder.
