Simple and ultra fast cross platform tool for lossless trimming/cutting of video and audio files. 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. It extremely fast because it does an almost direct data copy. It uses the awesome ffmpeg (included) for doing the grunt work.
Since LosslessCut is based on Chromium and uses the HTML5 video player, not all ffmpeg supported formats will be supported directly. 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.
New in v1.11.0: Unsupported files can now be remuxed (fast) or encoded (slow) to a friendly format/codec from the
File menu. A processed version of the file will then be opened in the player. The cut operation will still be performed using the original file as input. This allows for potentially opening any file that ffmpeg is able to decode.
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.
