Server Version#: Version 1.24.5.5173 Player Version#: How can I get Plex Media Server to display PGS subtitles from the MKV ?

Ok, thanks for confirming! Could you activate debug logging (not ‘verbose’!) quit Plex Server wait 1 minute start Plex Server wait 2 minutes select the PGS subtitle on the preplay page of that movie, then play the movie for ~1 minute wait 3 minutes fetch log files and attach them here

by using a server machine which is able to perform video transcoding fast enough by using a plex client type which can understand the PGS subtitle format on its own (e.g. Plex for Windows, Plex HTPC , or Plex for Android) i.e. NOT the plex web app

The machine where the Plex server is installed has Geforce GTX 1650 video card, and I have Plex Pass. So, the hardware transcoding works. Yet, it does not show me the PGS subtitles

Burning in subtitles is not reliant on hardware transcoding. It uses 100% software, so the main CPU needs to be fast enough. Are you certain that the PGS subtitle has been ripped correctly? Is it visible in a regular desktop video player like MPC-HC or VLC?

Yes, the subtitles are visible in MPC-HC (PS: PGS are only being “treated” in software? I didn’t know that) The Plex server is installed on a HP Z620 machine, with 96GB DDR3 Quad channel and 2 * Xeon E2667 v2 3.3GHz with 4 GHz Turbo frequency

The movies I was asking about was 1080p but it was encoded with H.256 Could the codec I used be the problem ?

[image] dan_mihai_moldovan_gmail_com: Could the codec I used be the problem ? It should not be a problem, if your hardware transcoding works correctly. Is it using 10-bit color/HDR?

No it is not HDR. It is only SDR. I only transcoded it to H.265 in order to save some HDD space It is 8 bit H.265

If you convert the PGS subtitles to SRT, everything works as expected? [image] Introduction: convert image-based subtitles to SRT with Subtitle Edit Tips, Tricks & How-Tos This is a short introduction into how to convert image-based subtitles (PGS, VOBSub etc) to text-base…

I didn’t try to convert those PGS to SRT, but STRs do work perfectly. I did find a SRT subtitle for this movie and it works perfectly
