LosslessCut

LosslessCut is a cross-platform program from Mikael Finstad for losslessly trimming/cutting video and audio files. (It’s based on FFmpeg, Chromium, and Electron). Other features include:

  • Lossless re-merge of selected segments (for cutting out commercials etc.)
  • Lossless merge of arbitrary files (with identical codecs)
  • Lossless extracting of all data streams from a file (explode video, audio, subtitle and other streams of a file into separate files)
  • Take full-resolution snapshots from videos in JPEG/PNG format
  • Manual input range of cutpoints
  • Can include primary streams (audio/video), or all streams
  • Can remove audio track
  • Apply a timecode offset
  • Remux into different output format
  • Change rotation/orientation metadata in videos. Great for rotating phone videos that come out the wrong way without actually re-encoding the video.

LosslessCut 2.7.1 is freely downloadable open-source software for OS X 10.10 and later, Linux, and Windows.
