De DVB ondertiteling van BBC-entertainment is recent aangepast.

 

Als je nu in de opties voor de DVB-ondertiteling de ondertitels wilt centreren, althans als je deze optie aanzet, want de ondertitels zelf zijn al gecentreerd, dan wordt de onderste lijn gestoord weergegeven.

 

Indien je deze optie afzet dan worden de ondertitels goed weer gegegeven.

 

E.e.a. is geillustreerd in de bijgevoegde screenshots.

PS: Ik ga natuurlijk te horen krijgen dat ik eerst moet updaten - dit is nl op een 7.1 image.  Maar ik veronderstel dat het in de meest recente image niet anders is.  Althans in 7.3 is dit effect ook te bewonderen.

Dit probleem zit er al sinds dag 1 in (minstens 15 jaar dus ), en is recent door onze nieuwe "contributor" BCW gefixt. De fix zit in 8.0-rc.

 

Edit: correctie, er zijn andere issues gefixt, dit probleem is nog in onderzoek.

1 ) funny, when somebody using "center" for centered subtitles and see "problem"...

 

2 ) "what 15 year old problem" ??? It was feature for "clearing" rest-outlines of centered subtitles, when the lower parts of the letters as "j, p, y, q ..."  (3 lines) extended into the lower region => centering moved top region, but rests were still in bottom region.

 

 

'Fix' was removing this feature only. It should be changed to:  "No", "Centered", "Centered with clearing". But as I saw, providers on dutch services finally learned to broadcast subtitles centered and using smaller characters.

Please discuss this with Ben.

It is not funny.  The centering option for DVB-subtitles is standard on because this setting is all or nothing setting.  If you select it, it is selected for every channel.

And I want it for some other channels.

 

So I observed the problem on BBC-entertainment

[BCW]

The artefact can also be seen in other stations, for example in some German stations. 

Attached a screenshot from SWR HD. You can see two lines, also in the top subtitle. It always occurs when the subtitle region is split up in different objects. 

The issue has been addressed and has been uploaded by WanWizard. I expect it to be available at the next build.

 

@IMS:
According to the DVB spec, objects may never overlap. Moreover, centering the contents of a region should not affect its width or height. If it does, it's a bug and should be fixed, and not by erasing part of another region. If you have an example, please tell me where I can find it. Or better still, if you can, make a recording.

Can a moderator change the thread title please so that it mentions subtitle ?

 

The aretafct bug is present on ViX too. A screenshot of SWR HD on 19.2 also attached. You have to select the DVB subtitle, not teletext.

actually this option is stored per channel if you set it in Subtitle Quickmenu (yellow > yellow > blue > <Center DVB subtitles)...

The commit seems to have made it worse for me. Using a Gigablue UE 4K. Screenshot of SWR HD on 19.2

Changes to software can have undesirable side effects - and good testing is essential, but often laborious.

 

However, in this case I would be surprised if this effect is caused by the most recent modification.

I have seen similar effects when the menu item 'Use original DVB subtitle position' (on the quick subtitle menu)  is on 'Fixed'.

Could you please check that if you change this setting to 'Original' the effect is still there?

 

A few days ago I made a screendump from a recording with the Fixed settings. You can see the same effect. I did this before the change I made, as you can see from the horizontal line in the bottom region.

Original = Fine

Fixed= Problem

[BCW]

Hello Abu Baniaz,

Could you please make a screenshot with the quick subtitle menu showing (as you did in your earlier post of 25 December)?

Thanks!

Ben

As requested. The center option was not relevant as it had issue with both yes and no

Thank you.

In both shots I noticed that the Use original DVB subtitle setting is Fixed.

Could you please change this to Original?

[Abu Baniaz]

As an aside, there was a bug that affected UK subtitles. It was fixed with this

https://github.com/O...1b4920de684bb3c

 

But that got reverted because of an issue with some Norwegian subititle. There was no response to a request for a recording so that it could be looked at further.

 

EDIT:

Video to issue is here

Original is fine 

[BCW]

How about the new version? Could you check that as well, please? Screendump would be great...

Off to work, will try later. I have edited earlier post an included a link to the video of issue.

[BCW]

Sorry, I think I misunderstood your last message. I took it to mean that the 'Original' meant the image without the last commit. And I took Fixed to mean my fix, as opposed to the Fixed position...

But if I understand correctly now, the modification works well if the 'Use original DVB subtitle setting' is set to original. So it's OK?

With reference to your video - these are stenographic subtitles, quite common in uk transmissions. The issue shown was addressed in earlier commit (https://github.com/O...68812a9fa2f71f2) and should no longer be an issue.

 

Do you have details on the problem with Norwegian transmissions?
