Occasionally transparent subtitles

[Chetwood]

I've tried Elysium BD forced subs with MKV passthrough which works. They are identified and muxed into the mkv. However, when I play them back with VLC, they are only briefly visible and some items are skipped entirely. Remuxing with MKVToolnix fixes this.

Hi,
Please update to the latest version V9.1.2.1 and try again!

Thanks for taking a look to the issue.
Tested with this version.

First impression => YES, subtitles are working.

Second impression => they are working yes, but filled-in color seems to be too dark. Font edges are too rough, especially clear on italic-fonts.
Closer look reveals that there is indeed lighter grey pixels in the near edge than this filled-in grey.

For now I didn't have more time to do deeper analysis. So I'm not sure is this "too dark color" shown also subs on other movies or only this problematic one.

Subtitle

We will check this problem as soon as possible .

It's no authoring thing but a bug in DVDFab. If you simply passthrough the sub it works. But when you convert it to Vobsub or burn it in, the colors are off. So DVDFab is doing something it shouldn't be doing.

I've done some more testing on this one.

Found an alternative way to get subtitles correctly. Not in DVDFab thou.

Free video conversion tool called HandBrake. Latest version has added support for PGS subtiles.

With this tool subtitles are working as they should.

So, where ever the original fault is on. Fact is that DVDFab can be fixed to handle these correctly.

Maybe this title (and some others) have some "special" version or badly authored PGS subtitles.
But problem seems appear when extracting or rescaling is needed.

Could it be possible that someone of the developers take a look at this one?

Having the same issue with Essilum (or however you spell the movie).

These are both Sony movies. But, yes, all I get is an outline. However, when the iso (or the disk itself) is played back with PowerDVD11 the subtitles look just fine. So I'm wondering if it's DVDFab that's seeing something strange and only putting the outer portion of the title up when it's burned into the rip.

Authoring. Well that doesn't tell anything, does it.

Blu-ray Disc is nothing but video/audio streams and huge amount of authoring.

Maybe I need to give more detailed info about situation if my point was missed.

Subtitles are show correctly white if you watch video from:
- original disc
- ripped full disc
- m2ts/mkv/... passthrough file

Subtitles becomes transparent if you:
- extract subtitles to external file or render to video

So most likely error is in authoring.
But question is;
- is it authoring error on original disc or in dvdfab.
- if on disc; is this intentional (aka some sort of protection) or just "bad" authoring.
- which one ever; dvdfab gets fooled by this and can't handle subs correctly.

Just guessing: is there some kind of subtitle color or even transparency setting on BD subtitle stream(s) which may cause this.

Yep, the authoring!!

I have faced this really rarely but sometimes this kind of titles pops up.

This time After Earth.
And to be specific, sample is from Alternate Opening extra.

Ripping subtitles to external file or render to video subtitles are transparent. (As shown on attachment)

Past years I've done this same process several times and there is handful of titles which have something funny on the subtitles.

Does anyone know what is causing this?
Maybe some rare/special/illegal subtitle format?
