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.

### 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.

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.

- Output videos will have an empty portion in the beginning, see discussion in [#13](https://github.com/mifi/lossless-cut/pull/13)
- If you get an error when cutting any kind of file under Windows, please check your anti-virus. It might be blocking execution of ffmpeg, see [#18](https://github.com/mifi/lossless-cut/issues/18)
