Many people would record the TV shows or download the TV series to collect all the episodes then watch them with Plex on TV, Xbox One S, PS4 Pro, PS4 Slim, Roku via USB hard drive or NAS server. In this way, you don't have to watch the advertisement and if you like, you can fast-forward through the part you don't like.  However, the feedback unveiled that Plex can't recognize MP4 TV shows and movie files sometimes. In our cognizance, MP4 should be supported by Plex but why Plex can't play MP4 files as we expected.

Why Plex Can't Play MP4 Files Sometimes?

In Plex supporting page, we can see that Plex's native video support is typically (but not always) limited to the MP4 container, H.264 video encoding, and AAC audio. Content matching the following can usually be Direct Played:

  • Container: MP4
  • Resolution: 1920x1080 or smaller
  • Video Encoding: H.264 (level 4.0 or lower)
  • Video Framerate: 30fps
  • Video Bit Depth: 8
  • Audio Encoding: AAC

MP4 in H.264 video codec and AAC audio codec can be directly played by Plex. But as a video container, not all MP4 video files are encoded with H.264 and AAC codec. Many MP4 video is encoded with H.265/HEVC, XviD, DTS and other codecs, which are not supported by Plex. In addition, when we have many TV series episodes, the TV Show names can lead the MP4 playback issues on Plex. When we play external MP4 files on Plex via USB, the wrong place where we store our MP4 files also has an influence on Plex MP4 video streaming. In short, there are many reasons that can cause "Plex can't play MP4" isues. When you can't play your MP4 files on Plex, you can try the ways below.

How to Play MP4 Files on Plex?

Method 1: Naming Video Rightly

When your MP4 files are TV shows, it is important that both the folder structure and each episode filename be correct for shows to be correctly matched. To name series/episode based shows:

  • TV Shows/ShowName/Season XX/ShowName - sXXeYY - Optional_Info.ext

Where:

  • XX is the season number
  • YY is the episode number

...Optional_Info is additional optional text (e.g. episode title) that is ignored by Plex, and ext is the file extension. (Some operating systems such as Windows may hide your file extensions by default.)

/TV Shows
   /Grey's Anatomy
      /Season 01
         Grey's Anatomy - s01e01.avi
         Grey's Anatomy - s01e02 - The First Cut is the Deepest.avi
         Grey's Anatomy - s01e03.mp4
      /Season 02
         Grey's Anatomy - s02e01.avi
         Grey's Anatomy - s02e02.mkv
         Grey's Anatomy - s02e03.m4v

Method 2: Folder Nesting

MP4 movie files can be placed into individual folders if you want, but it's not mandatory in most cases. If you have external media for a MP4 movie (e.g. custom poster, external subtitles etc.) you should usually place the mp4 movie in a nested folder along with the custom media files. Name the folder the same as the movie file:

  • /Movies/MovieName (release year)/MovieName (release year).ext
/Movies
   /Avatar (2009)
      Avatar (2009).mkv
   /Batman Begins (2005)
      Batman Begins (2005).mp4
      Batman Begins (2005).eng.srt
      poster.jpg

Method 3: Make MP4 Encoded with Plex Compatible A/V Codec

When you named your MP4 TV shows rightly and put them in a folder called movie and still can't play MP4 video with Plex, you might need to check if the MP4 video is encoded with Plex compatible video and audio codec.
