  • How do I make mkv files show a cover image in files explorer?
    Icaros can allow the Windows File Explorer to display a cover art image as the thumbnail if there is an appropriate image embedded in the video file. You can embed a cover art image into MKV files using MKVToolNix. Make sure to follow the MKV attachment specifications, otherwise, the cover art may not display properly. - Source: Reddit / 1 day ago
  • how do I download the subtitle files from Jellyfin like how you can download the movie file?
    Don't store the subtitles in a separate file - put them in the video file's container (MKVToolNix does the job well, both through the GUI and through the command line - plenty of video tutorials on the subject). - Source: Reddit / 16 days ago
  • Are AppleTV shows encoded differently?
    Okay, I suspect it's the subtitle issue, basically some Samsung TVs have an issue with loads of srt subtitles being muxed into the .mkv file (I think 20 or more) so what you need to do is add your episode to MKVToolnix and uncheck all the subtitles to remuxed into an mkv with no subtitles then add that back to Plex, restart Plex and try and play the episode. - Source: Reddit / 16 days ago
  • Help with home video orientation
    If you're concerned about losing quality by transcoding, this thread suggests that MKVToolNix can be used to simply insert a "rotate" tag into the container. I haven't tried it myself, but if it does work, it'll be massively faster than transcoding. - Source: Reddit / 18 days ago
  • Same movie, two VIDEO files, two different languages?
    In the case of the latter (i.e., the audio could synchronise if offset sufficiently), you can use MKVToolNix and appropriately offset whichever audio you're importing. It'll take some fiddling to get it just right, but it will work (once again, assuming that the framerate is the same). - Source: Reddit / 19 days ago
  • With each update less .mkv movies play sound?? Is there some files to avoid?
    All your videos have to use AC-3, if you remux with MKVToolNix use the AC-3 Track for all your videos. - Source: Reddit / 21 days ago
  • Setting up external HDD for library
    You can create a separate folder for each movie, but that creates an absolute mess. Don't store posters on the media drive; Jellyfin will download them and store them in its metadata store. Subtitles are best multiplexed into the media files themselves (use MKVToolnix), but if you must store them externally, simply name the subtitle identically to the associated media (for example, for Happy Gilmore (1996).mkv,... - Source: Reddit / about 1 month ago
  • Is there a program that has the ability to match up with audio and subtitles together like a timestamp?
    I use it allows to set a positive or negative delay and on the occasion of adding a subtitle track that is at the wrong speed you can stretch it also. - Source: Reddit / about 2 months ago
  • Horrible Plex LAN Performance
    Try remuxing the file with MKVToolNix or similar tools. - Source: Reddit / about 2 months ago
  • Embedding and sending subtitles to use with external player?
    You can use MKVMerge to mux subtitles into the MKV container;. - Source: Reddit / 2 months ago
  • Modifying .ASS subs for TV viewing
    Finally, use MKVMerge to mux the subtitle files into your media:. - Source: Reddit / 2 months ago
  • major slowdown/problems with subtitle burn-in on a Intel® Celeron® Processor B840 2M Cache 1.90 GHz (2-core) chromebox. Watching using Firestick 4k Max. What specs should I shoot for?
    u/GetInHereStalker, once you've converted the subtitle to a text format (SRT, ASS, etc.), you can re-mux it back into the MKV container to avoid having separate files - use mkvmerge from the command line or MKVToolnix GUI (both in the MKVToolnix suite). - Source: Reddit / 2 months ago

    You can do that with - Source: Reddit / 2 months ago
  • Trying to remove the SUBRIP part of the subtitles, any ideas? I've tried everything
    You can use mkvmerge (part of the MKVToolnix suite) to strip subtitles from files, or simply make them non-default (and non-forced). - Source: Reddit / 2 months ago
  • TrueHD 7.1 and EAC3 5.1
    Simply use mktoolnix to open the mkv, disable the truehd track, save it as a new mkv, delete the old one. - Source: Reddit / 2 months ago
  • Download only audio portion of a stream?
    Note that you don't actually need to re-encode anything. SMPlayer lets you add external audio tracks to the video you're currently watching, and MKVToolNix creates MKV containers from different audio/video sources without re-encoding the original tracks. - Source: Reddit / 2 months ago
  • Movies splitted in two parts "Now playing" problems
    Why not just use a tool like MKVToolNix and combine them into a single file. That is what I did on the 10-ish movies that I had that way. - Source: Reddit / 2 months ago
  • Request for help understanding file sizes.
    Go download MKVtoolnix-GUI.. Using the remuxing function you can append one video to the end of the last. So you drag in one video, then drag in part 2 and you append it, drag in part 3, select append, and so on and so forth for all the parts of your shot. - Source: Reddit / 2 months ago
  • Download audio in another lanugage
    Plex doesn't support external audio tracks, only way to do it is to merge with the file, you can use mkvmerge for that - Source: Reddit / 3 months ago
  • Is there any way to see why a sync failed?
    I've got Unamanic (almost the same as Tdarr) running on my UnRaid server where Plex lives. Still, moving a 4K encode from where it lives on my array to a temp directory, running it through MKVToolNix to strip out any Subs / extra Audio / etc.. and then letting Unamanic have it's way with it still leaves a pretty big file size. - Source: Reddit / 3 months ago
  • assembling a 5.1 scene list
    Yes you can use makemkv to rip the movies to your computer and then just queue them up on something like Plex Media Server and/or use mkvtoolnix to split the movie to the exact timestamps you want. - Source: Reddit / 3 months ago
