Splitting a video

[arrbee99 1712]

Am wondering if anybody knows how to split a video at a chapter marker, possibly using MKVToolNix (seeing as I've got it already). I've ripped a TV series using MakeMKV but its actually saved two episodes into one file, two chapters for each episode, so would like to split at chapter two. Have googled and it sounds easy to do but it seems to use commands that I can't even find (unusually for me).

Assuming you are on Windows

 

This script assumes the video,mkvinfo.exe and mkvmerge.exe are in the same directory as the script file

 

it creates an "output" dir below the current directory

 

it will split at all chapter markers - i.e. you get a file per chapter

 

Save below as a bat file

@[member="Echo"] off &setlocal EnableDelayedExpansion

set source=%~1
set destination=output\%~nx1

if not exist output\ mkdir output

for /f "usebackq tokens=4" %%i in (`mkvinfo --ui-language en "%source%" ^| findstr /i /c:"ChapterTimeStart: "`) do (
  if defined timecodes set timecodes=!timecodes!,
  set timecodes=!timecodes!%%i
)

mkvmerge -o "%destination%" --split timecodes:%timecodes% "%source%"

endlocal

and to join videos together you can use ffmpeg (could also use that for the splitting as well)

F:\Video\ffmpeg\bin\ffmpeg.exe -f concat -safe 0 -i F:\Video\testing\JoinFilelist.txt -c copy F:\Video\testing\output\output.mp4

and the joinfilelist.txt looks like this

file 'F:\Video\testing\output\part 1.mp4'
file 'F:\Video\testing\output\part 2.mp4'

Just change the video file extensions for you required output to mkv
