It may be at 100% CPU utilization and give you stuttering, buffering problems. Plex transcoding is really a CPU intensive process. And now, you can set segmented transcoder timeout, transcoder temporary directory, transcoder default duration, transcoder default throttle buffer, and background transcoding x264 preset. Maximum simultaneous video transcode means the maximum number of transcoding sessions are allowed to process simultaneously.įor more transcoding settings, you can click SHOW ADVANCED. ▪ Make my CPU hurt – highest quality with slower transcodes and heaviest CPU usage Plex transcoder quality and max simultaneous transcodes settings ▪ Prefer higher quality encoding – higher quality but slower transcoding If you want to make Plex transcode faster and don't mind some quality loss, you can choose this option. ▪ Prefer higher speed encoding – faster transcoding speed but lower quality streaming. This option is recommended to most users. ▪ Automatic – Plex Media Server will choose from the other three options automatically. There're four options under Transcoder quality. Go to SETTINGS, hit Transcoder, and now you can specify Transcoder quality and Maximum simultaneous video transcode. If it can, now you can download Plex Media Server from Plex downloads page, install it following the onscreen wizard, and finish server setup as required. To begin with, check whether your computer or NAS can meet the requirements of Plex Media Server. Plex transcoding process will be automatically enabled when necessary, but there're some Transcoder settings you can play with in advance. This is because network speed generally does not support full quality. When we remotely access the content inside Plex Server, Plex will first transcode the source video into a low-quality file to avoid buffering. In many Plex apps we need to burn the subtitles to video if we want to use subtitles. The video bitrate is higher than that required by the client app.ģ. The parameters of the source video are not compatible with the client device, such as codec format, container format, resolution, and bitrate.Ģ. Plex has discontinued the development of Plex Transcoder (but still available to use currently) and will replace it with Plex Universal Transcoder which is more powerful, faster, and smarter.ġ. These two transcoders are based on FFMPEG. This also varies by OS, but can be done by editing UMS' shortcut on Windows, editing ist on macOS or editing UMS.sh on Linux.Plex Media Server has built-in transcoders, with which it can convert media from an incompatible format to a compatible format while streaming media to a client device.Īt present there are two transcoders in Plex Media Server - one Plex Transcoder, the other Plex Universal Transcoder. To use a non-default profile folder, you must add "profile:" (where should be replaces with the actual path) to the command launching UMS. Moving the profile folder can be a bit more work, as it's not possible to configure in the configuration file (since the configuration file itself is in the profile folder). The profile folder defaults to different location depending on you OS, the location of this can also be found early in the log. These can be found in your "profile folder". UMS also creates a media database and some other files that are updated regularly. If the location isn't what you want it to be, you can set it manually by setting "temp_directory =" in UMS.conf. You can see the location used as a temp folder by reading the information at the start of the log. The location of the temp folder varies by OS, but UMS will try to use the "OS default location". There are however buffering (pipes) and other temporary files used. The transcoded data isn't stored anywhere, it's streamed directly to the renderer.
