Subtitles not displaying properly

[martincom 25]

I'm having a similar and maybe the same issue.  I was viewing the movie "Sum of All Fears" (recorded to Emby from BD).  The embedded viewer selectable subtitles and embedded subtitles for Russian dialogue were not displaying on playback.  This movie was recorded in theatrical widescreen format.  So on a 16:9 screen there will be horizontal black bars at the top and bottom of the screen.  The embedded subtitles were configured to display in the bottom black bar, not within the actual picture.

No portion of the subtitles appear on a Roku Ultra.  Only a fraction of the top portion of the subtitle appears on PC playback or on a onn streaming device.

So I'm speculating the embedded subtitle position, within the black horizontal bar of a widescreen format, is the issue.

If I change the display setting, within the user settings, from "Auto" to "Desktop", the subtitles will display when playback is from a PC.  When set to either "Desktop" or "TV" with subtitles on, neither will play at all from a Roku Ultra.  The screen will display the spinning black circle and cycle up/down through various percentages until it ultimately displays a red box that states a playback error has been encountered.

This sounds completely different so splitting to new topic.

Configured exactly where?

[pwhodges 2012]

If they are PGS subs, then the image containing them is the size of the video which may include black bars.  I have come across this as an issue when re-encoding videos with PGS subs - it is prudent to be wary of stripping the black bars for this reason (I've seen it cause trouble both for letter-boxing and pillar-boxing).

When performing playback from the BD.  I had assumed their position was fixed within the BD media.

All the subtitles are PGS, also.  We viewed another movie recorded from BD to Emby last night and it has the same issue.  Those subtitles were PGS, also.

Apparently, this is not a new issue.  Here is an article in this regard:

https://www.winxdvd.com/video-transcoder/pgs-subtitle.htm

The movies I'm having trouble with were MKV.

Is there a possible fix that can be done within Emby, similar to the transcode fix in Plex the article refers to?

Can we please look at an example?

 

Thanks.

Below is a screen shot from a PC playback, display set to "auto" in user settings, where just the top portion of the subtitle text is displayed.  The same issue occurs on a Roku Ultra and onn streaming device.  Log files attached.

But exactly how and where did you "configure the PGS subtitles"?  Was this when you ripped the disc?

[martincom 25]

I didn't configure anything.  When the movie was played from a BD player, the subtitles are displayed at the bottom of the screen, within the black horizontal bar area.  So I assumed that is where they are.  That was probably an incorrect assumption as if I change the display setting, in the user settings, from "auto" to "desktop", they will sometimes be displayed in full within the PC screen--but not always.  I haven't determined why sometimes they do and sometimes they don't.

As to how I end up with the subtitles on Emby:

1. Create MKV file from BD with MakeMKV app and selecting the desired subtitle languages when doing so.

2. Compress file with Handbrake, carrying subtitle selections forward within that app's subtitle tab.

Are you cropping it in that process?  If you don't, then I'm sure this issue will go away.

[pwhodges 2012]

And Handbrake crops by default, I think, so you need to check.

[martincom 25]

I never realize Handbrake was cropping, by default.  Sure enough, it is configured to do so within the profile I'd been utilizing.  That is likely the issue.  It'll be awhile before I can confirm.  We're between homes and all my source BDs are packed in a semi-trailer.

The problem is not the cropping itself, which is rather a good thing to do.

The actual problem is that it is cropping the video WITHOUT repositioning the subtitles. The subtitle positions are no longer valid after the cropping.

An upcoming update to the beta will fix those situations by automatically relocating all subtitle bitmaps to be inside the video frame size.

Just have Emby downloaded today, and found this issue both in Chrome and my Samsung TV

It looks like the Embedded subtitle has been shrinked & repositioned using 1080p instead of 4k(which is the video resolution)

Is this the same issue you mentioned here?

external SRT works fine.

Hi, please provide the emby server and ffmpeg log from an example. Thanks.

Either grab them from logs folder (Dashboard>three-dot menu next to Server name "Get Server Info" will list path) or you can download them in Settings>Logs tab (scroll down to "Advanced" sidebar section. DL button is rightmost one).

To add a few thoughts, this subtitle have effect i.e. translated the "newspapers, signs" from the movie and cover them in their position.

I just tried the other embedded subtitle with the same movie file which basically plain text and it's working correctly.

@martincom @Harris123 

Are you still able to reproduce this?

[martincom 25]

No, it was corrected some time ago.  I'm assuming softworkz resolved it in a following release, as he indicated.
