The purpose of this HowTo is to split videofiles which contain more than one episode of a tv show into single-episode files. So they show up individually within plex, can be played individually and don’t produce any of the weird things that multi-episode files are plagued with.
Using MKVToolNix GUI v9.1.0 to merge multiple video files. In this example I combined a a video clip consisting of just a title with an actual video. Ffmpeg -i input.mkv -codec copy output.mp4 It auto-detects a Matroska to MP4 container conversion based on input/output filenames.codec copy stream copies, or 're-muxes', the streams from the input to the output without re-encoding. Think of it like a copy and paste. MP4 Output Hi I was wondering how you can create an MP4 output. The video I have is MP4 and I just need to add an audio track and want to keep the same file size but it outputs as MKV or if I manually change it to MP4 iTunes won’t read it.

A GUI in C#.NET 4 for mkvextract (MKVToolNix) A GUI for mkvextract utility (part of MKVToolNix) which incorporates most (if not all) functionality of mkvextract and mkvinfo utilities. Written in C#.NET 4.0, in order to attain high compatibility with Windows OS (WinXP and newer Windows), as well as Linux through Mono (v1.6.4 and newer), and perhaps OSX (not. Main issue with MkvToolNix is the lack of subtitle support when converting MP4-MKV container. Other than that it’s an excellent tool, and frequently updated (if someone knows how to retain the subs without having to extract/add them back in, please share). And of course cmdline ffmpeg always for the win!
Mkvtoolnix Gui
The tool used is MKVtoolnixGUI
it is freely available for all major PC operating systems.
Therefore the container format of the output files will be MKV.
The input format can be a multitude of containers like AVI, MP4, MKV, MPEG, TS, DIVX and several more.
The quality of the files will remain the same, because mkvtoolnix only remuxes the files, it doesn’t re-encode them.

start up MKVtoolnixGUI
(depending on your operating system, this might look a little bit different)drag the multi-episode file into the window marked by my crude arrow
the video, audio and subtitle tracks it contains will appear in the window underneath it
you may want to revise the language code that is assigned to the audio track(s) and the language and ‘forced’ attribute of subtitle tracks so the Plex interface informs you correctly about the languages available.
Plex’s automatic audio and subtitle track selection feature relies also on these tags to work correctly.change to the Output tab:
change ‘Split mode’ to ‘after specific timecodes’
input the timecode of the episode break into the field ‘timecodes’ (you can input several timecodes [separated by comma] if your source videofile contains more than two episodes)
(I chose to split after 25 seconds, because my example file is only 59 seconds long)revise the path and filename in ‘Output file’ to your needs
click Start muxing

You should find 2 or more MKV files in the destination path, their file names appended by a three figure number (DVD Introduction-scene-001.mkv and DVD Introduction-scene-002.mkv for our example file in the screenshots)

Now rename the split episode files according to the Plex naming guide for tv show episodes and add them into your library.
Done.

If you set above as ‘Split mode’ = “Before Chapters”, you can split your files on chapter markers.
This is particularly useful when you have ripped tv shows and you got only one monolithic file instead of one file for each episode.
