Clayzee 4 Posted May 10, 2023 Share Posted May 10, 2023 Hello I currently have the following Emby setup : server : Emby on Synology DSM7 ( transcoding disabled ) client : Apple TV 4k (3rd gen) NB : transcoding being disabled on the server side, the client always uses DirectPlay Currently, playing media(s) with PGS subtitles result in these being displayed in a grey color, without any background ( making them hard to read ) -> I would to change the subtitles colour and/or style : how can I achieve that ? Â Thanks beforehand for any help ! Â Â Â Â Link to comment Share on other sites More sharing options...
rodainas 188 Posted May 10, 2023 Share Posted May 10, 2023 PGS subtitles are image based extracted from Blu-ray, those aren’t customizable. The customizable format is srt (subrip). You need to convert those to srt (expensive cpu process) or simply just download a new srt file from any subtitle provider site (recommended).

But ... why is the rendering totally different from one client to another then ? eg : I get grey subitles on Emby, while playing the same media on VLC gives white subs with black borders  Link to comment Share on other sites More sharing options...

They’re probably sub rip. Can you please provide an example? Link to comment Share on other sites More sharing options...

Solution Clayzee 4 Posted May 12, 2023 Author Solution Share Posted May 12, 2023 I ran another test with a non-HDR video media and PGS subtitles : the colour / style is rendered as expected So, the root cause for this greyish subtitles' colour seems to be the Apple TV not passing the HDR signal when playing an .mkv file  1 Link to comment Share on other sites More sharing options...
