Why convert VOB to MKV?
VOB files are split across multiple 1 GB chunks tied to a DVD's folder structure, making them awkward to play without the accompanying IFO files. .MKV consolidates an entire title into one self-contained file that most media players handle directly. It also stores multiple audio tracks, subtitle streams, and chapter markers in a single container - matching what was on the original disc.
How to convert VOB to MKV
MakeMKV FREE
Open your VIDEO_TS folder in MakeMKV, select the title, and click Make MKV - it remuxes losslessly in minutes with no quality loss.
HandBrake FREE
Open your VIDEO_TS folder, set the format to MKV, choose H.264 or H.265, then click Start Encode for a significantly smaller file.
Command line - ffmpeg CLI
Remux a single VOB losslessly with ffmpeg -i VTS_01_1.VOB -c copy output.mkv - note this omits chapter data stored in the IFO file.

- MakeMKV remux preserves original MPEG-2 video and AC-3 audio with no quality loss; file size stays close to the source VOBs. HandBrake re-encoding can cut size by 50-80% but takes longer.
- DVD subtitles are bitmap images (VobSub), not text - they carry over to MKV as image-based tracks, not SRT, so text search and styling are unavailable.
- Chapter markers live in the IFO file, not the
.vobitself - always point MakeMKV or HandBrake at the fullVIDEO_TSfolder rather than individual VOB files to preserve chapters.
