- Undo/redo
- Give labels to cut segments
- View segment details, export/import cut segments as CSV
- Import segments from: MP4/MKV chapters, Text file, YouTube, CSV, CUE, XML (DaVinci, Final Cut Pro)
- Video thumbnails and audio waveform
## Example lossless use cases
### Remove audio tracks from a file
### Add music to a video (or replace existing audio track)
### Link audio and video tracks from separate recordings
### Include a subtitle into a video
### Extract music track from a video and cut it to your needs
### Cut out commercials from a recorded TV show
Without having to re-encode. You can also change format from TS to MP4 at the same time.
### Fix rotation of a video that has the wrong orientation flag set
Great for rotating phone videos that come out the wrong way without actually re-encoding the video.
### Quickly change a H264 MKV video to MOV or MP4 for playback on iPhone
### Import a list of cut times from other tool as a EDL (edit decision list, CSV) and run these cuts with LosslessCut
### Export a list of cut times as a CSV EDL and run these in another tool
### Loop a video / audio clip X times quickly without re-encoding

### Difference between App Stores and Github download
They have exactly the same in-app features, except a few platform limitations. Apple doesn't allow opening VOB files with App Store apps. Apple App Store apps need to prompt for output directory. LosslessCut version in the App Stores lags a few versions behind the GitHub version, because I want to be sure that the new features work perfectly before releasing in the App Stores. GitHub version can contain new, untested features and may contain some bugs. I consider the newest GitHub versions to be a "beta" test.
## Supported formats
Since LosslessCut is based on Chromium and uses the HTML5 video player, not all ffmpeg supported formats will be supported smoothly.

Note: The original video file will not be modified. Instead it creates a lossless export to a new file in the same directory as the original file with from/to timestamps.
Note also that the cut is currently not precise around the cutpoints, so video before/after the nearest keyframe will be discarded. EXIF metadata is preserved.

## CSV import/export
The CSV export/import function takes csv files with one cut segment on each line. Each line contains three columns: `segment start`, `segment end`, `label`.
`segment start` and `segment end` are expressed in seconds or left empty. Empty `segment end` means segment ends at the duration of the video.
