 **The swiss army knife of lossless video/audio editing**
 
-LosslessCut aims to be the ultimate cross platform ffmpeg GUI for extremely fast and lossless operations on video, audio, subtitle and other related media files.
-The main feature is lossless trimming and cutting of video and audio files, which is great for saving space by rough-cutting your large video files taken from a video camera, GoPro, drone, etc. It lets you quickly extract the good parts from your videos and discard many gigabytes of data without doing a slow re-encode and thereby losing quality. Or you can add a music or subtitle track to your video without needing to encode. Everything is extremely fast because it does an almost direct data copy, fueled by the awesome ffmpeg which does all the grunt work.

 ## Supported formats

+Since LosslessCut is based on Chromium and uses the HTML5 video player, not all FFmpeg supported formats will be supported smoothly.
 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.
 
-Unsupported files can still be converted to a supported format/codec from the `File` menu. (Try fastest variant first.) A low quality version of the file (without audio) will then be created and opened in the player. The cut/export operation will still be performed on the original file, so it will be lossless. This allows for potentially opening any file that ffmpeg is able to decode.

 Note also that the cut is not precise around the cutpoints, so video before/after the nearest keyframe will be discarded. EXIF metadata is preserved.
 
 ## Known issues & limitations
 
 - **Cutting times are not accurate!** Start cut time will be "rounded" to the nearest **previous** keyframe.
-  - Lossless cutting is not an exact science. For some codecs it just works. For others you may need to trial and error depending on the codec, keyframes etc to get the best cut. See [#330](https://github.com/mifi/lossless-cut/issues/330)

   - Your mileage may vary when it comes to `Keyframe cut` vs `Normal cut`. You may need to try both, depending on the video. [ffmpeg](https://trac.ffmpeg.org/wiki/Seeking) also has documentation about these two seek/cut modes. `Keyframe cut` means `-ss` *before* `-i` and `Normal cut` means `-ss` *after* `-i`.
 - When exporting you may lose some proprietary data tracks (like `tmcd`, `fdsc` and `gpmd` added by GoPro). These can be exported to separate files however
 - Some codecs are not supported natively. There is partial support with low quality. You can convert to supported codec from the menu, see [#88](https://github.com/mifi/lossless-cut/issues/88)
