Flickering subtitles

Postby daanvandam » Tue Aug 19, 2014 9:59 pm

I was streaming a .mkv movie to my PS3 when I noticed something. The subtitles were appearing for a split second before they're supposed to, and after that quick flicker they appear correctly. It is really bugging me and I wanted to know if I can fix this. I find it very hard to explain but that's all the information I can give. I also think the subtitles are in the MKV file because I have no other files in the folder other than the .mkv .

I am running PMS on a windows 7 desktop computer

Thanks in advance.

I have noticed the same issue only with the original subtitles that come already included inside the mkv file (originally they come with the original bluray disc).
What I do is simply download external subtitles, put the external subtitles with the same folder as the mkv file (both names of mkv & subtitles file have to be exactly the same), & choose to play the mkv with external subtitles.
Hope this helps.

Hello.

I've the exact same problem has you have, and I really cannot watch a show when that problem arises.

It only happens in some shows, when those shows have multiple subtitle tracks (mainly PGS or .SUP).

The Mediainfo of a show where that problem happens happens:

The problem is that some shows (mainly anime) do not have external subtitles for them, especially for that specific release, that's why it's important to solve, or at leat work around this issue.

Regards.

Here is a sample video of the problem:

Yes, that is the problem.

I did find external subtitles - and I muxed them with the video, but it still happens, so I guess my last option is to just re-name them and try that. I am using the latest UMS, because PS3Media Server us no longer being updated. It still happens with UMS 4.1.1 though.

External subtitles don't display for me...despite if I mux them, they work, but still flicker on the Media-server. They do work with my media-player though.

Are you talking about .srt ou any other external subtitles?

Are you renaming the subtitles, so they have the exact same name as the show they belong, and then are you going to the transcode folder and selecting them? And even so they are not displayed?

The external subtitles DO show up in the Transcode folder, the issue is if I select them - no subtitles appear. Yet if I load the subtitles on PC, with the same media file, they do, and yes, they have the same name. They're .sub files. P3MS shows them as VobSubs in the Transcode folder.
