How to split MKV file



  By Olga Krovyakova - modified September 29, 2023, created March 26, 2019

MKV file format provides high quality of video and sound, but files of this format are usually large. Therefore, it is often necessary to split MKV files into smaller parts to, for example, burn them on DVD discs.

This article describes how to easily and quickly cut a MKV file into several parts or save one fragment using SolveigMM Video Splitter. It works with frame accuracy and needs no decoding. It keeps the quality of the source and doesn't cause audio/video desync. The same procedure can be used for cutting and trimming AVI files as well as MPEG-2, MP4, MOV, AVCHD, MPEG-1, ASF, WMV, MP4, WMA, WAV, WEBM files.
