But yeah well: When converting the 256 color palette of a BD/HD-DVD-SUP to a "4 out of 16" colors VobSub palette, BDSup2Sub looks for the brightest opaque color which is used for the most pixels. It then selects the closest color from the default VobSub palette than can be displayed and edited via the "Edit Vobsub Palette" menu entry. In your example, the yellow is very light and thus closer to white than to the yellow in BDSup2Sub's default VobSub palette. You can edit the yellow color in the VobSub palette though as described in the online help. You can even save and load your own custom palettes. There are some limitations however: due to the restriction to a 16 color palette and BDSup2Sub's (minimum) antialiasing approach for VobSubs which needs a light and a dark tone for each color, there are only 6 colors than can be adjusted (plus white/grays). So if there are more colors used in the SUP, some colors will be always wrong. Besides, due to the limitation to 4 colors (where one is transparent) in one caption, having two primary colors in one caption will always lead to (at least partially) wrong colors. |

I will post a few samples tomorrow, but I think the problem is not a BDSup2Sub bug. |

Hello Ox,
Indirectly you've solved MY problem. I was using an old version of the SubtitleCreator, ver 2.0 !! Your last reply made me obtained the latest v2.23rc1 since 07/2008...voila! You may want to update your 1st post to caution this similar pitfall... Cheers! |

Another major (though it might not look like it) update. I changed even more things than in 3.6.0 and tested even less, so give it a try, but don't be surprised if I screwed up some things.
18.05.2009 3.6.0 -> 3.7.0

Code:
id: xx, index: 0 timestamp: 4294967284:4223384455:4294967266:000, filepos: 000000000 timestamp: 4294967284:4223384455:4294967267:000, filepos: 000005800 timestamp: 4294967284:4223384455:4294967266:000, filepos: 000006000 Anyway, even if we ignored this, the SUB seems to be completely corrupt as well. Obviously there's not a single valid control header offset in it and I couldn't find any sensible control header either. Instead, the whole file consists more or less of padding bytes. Each packet is only about 0x100 bytes long. So if there's an image encoded somewhere, it must be either very small or spread over a lot of packets without any obvious reason. Dunno if it makes sense to look deeper into this. IMHO this looks like the export of a defective tool (no matter if it was the authoring tool or the demuxer). Both SubtitleCreator and VobSub SubResync crash on import. And really: this doesn't look like there's usable data in there anyway. |

I extracted these "subs" from a .ts file, which mediainfo identified as "teletext". I used mencoder as I do for DVD extraction. Thanks for the effort! Dean |

Dunno too much about how teletext data is defined in a TS transport stream. I would be surprised though if if was encoded in a subtitle substream.
I would assume that e.g. the demuxer didn't know what to do with it and stuffed it into a subtitle stream, but then couldn't get the information to create a valid IDX file and the control headers inside the SUB. Anyway, as far as I remember, I once extracted/converted a teletext subtitle stream from a DVB transport stream with ProjectX and then used it to create a DVD. So this would be worth a try. |

This is a TS with 4 audio and 8 subtitles. You can play this file and change the audio or subtitles in VLC. Do you think is possible to extract the DVB Subtitles (with some tool) and convert them with your program? I don't know any tool which can extract DVB Subtitles. DGAVCIndex "saw" them as AC3. CCExtractor cannot extract them because are not Closed Captions. Closed Captions can be found and extracted with this tool in several formats if the video is MPEG2 in TS.
enjoy, Mtz edit: PS: thank you for the implementation of "overlaped subtiles". Now the date and time from HD cameras are displayed OK without any gap. Will be nice if possible to move them on horizontal, not only vertical Last edited by Mtz; 21st May 2009 at 22:05. |

Well, this seems to be more or less exactly what I just discussed with deank: this is a DVB transport stream with embedded teletext.
So you need ProjectX or any other tool that can extract teletext subtitles from a DVB transport stream. AFAIK ProjectX only exports to SUP/IFO, so you need another tool to convert that to VobSub. SubtitleCreator or DVDSubEdit should do the trick. |

The question was about extracting the captions and ProjectX can export the captions from that stream.
Besides: this is pretty offtopic, so please open a new thread if you wish to discuss extracting DVB transport streams any further. |
