  • Lossless trimming and cutting with an almost direct data copy, so it is extremely fast
  • Discards gigabytes from camera or drone footage without a re-encode and without quality loss
  • Covers most mkvextract and mkvinfo functions in one window
  • Saves typing long mkvextract command lines
  • Cuts land on keyframes unless you allow a re-encode, so trims are not always frame exact
  • It is a cutting tool, not an editor: no titles, transitions or colour work
  • Needs MKVToolNix installed separately
  • Windows only, built on .NET Framework 4.0
