Hi, some of the Blu-rays from my country are really crappy, for example Planet 51 has an "all powerful" Dolby Digital 5.1 Spanish track at 256 Kbps!!!
But the problem is not the increased file size, is the not necessary re-encoding, I tested The Town Blu-ray disc, the dubs were Dolby Digital 5.1 at 448 Kbps, and the Director's Comment was Dolby 2.0 at 192 Kbps, these are DVD Compliant bitrates but BD-Rebuilder is re-encoding the tracks, that is my "bug report".

When the .xml is opened in Internet Explorer/XML editor, the sequence is reversed! When I open the .xml in a text editor, the sequence is as you expect it to be. I tried another 720p disc, a BD9 movie only created by BD-RB from the original Blu ray disc. No preprocessing of the sups with the exception of selecting the 3 sup tracks of one language only for the BD9 backup. But still no luck with the subs for the Alternate DVD from this BD9 movie-only source. The start and end times in the .xml are correct, but now the subtitles have not been muxed into the .vobs. From the log: Code:
- [01:26:51] Building ALTERNATE OUTPUT Structure - [01:29:05] Converting 3 subtitles to DVD format. - Unable to convert subtitle: 4608, ignored. - Unable to convert subtitle: 4609, ignored. - Unable to convert subtitle: 4610, ignored. - [01:31:46] Starting MPLEX. - [01:35:31] Building DVD File Structure. [01:39:54] - Encode and Rebuild complete I'll try now using the original BluRay disc as source (although you have certainly tested it exhaustively, and other posters have reported success.... so something my be odd just here, and no point in wasting your time on it). Edit 1: Could the problem be related to the 23.976 to 25 fps PAL conversion? I am using ALTERNATE_PAL=1 (no adding of frames). Edit 2: The subtitles work when using the original BluRay as source rather than the 720p movie-only backup as in my previous tests. However they loose sync, I suspect because of the 23.976 to 25 fps video conversion with ALTERNATE_PAL=1. I think if I accept ghosted frames (ALTERNATE_PAL=0) the sync of the subtitles would be maintained. Last edited by Sharc; 25th April 2011 at 13:27. Reason: Edit 2 |

Oh well, I guess there is no limit to the lunacy of some disc authoring houses. I do doubt seriously, though, that any human ears could detect a quality drop for a source that was reencoded at a higher bitrate than the original. I realize that any reencoding could result in some degradation -- but if a human can't hear it, does it really matter? But... if it doesn't have to be reencoded, there's really no reason to do it, so I'll add the check. It'll keep the purists happy. Hmm... that reminds me of a saying: "If a man speaks in the forest and there is no woman there to hear him -- is he still wrong?" Last edited by jdobbs; 25th April 2011 at 14:21. |

@Sharc
Well, it doesn't appear to have anything to do with ALTERNATE_PAL=1. I just did a feature to PAL and the subtitles are perfect. I'll create a 720p source and run it against that next. Honestly, though, I can't imagine why that would cause issues... but you never know. |

I found the time stamps in the XML to be the same as those of the original 23.976 fps .sup file. Therefore I concluded that this could be the reason for the sync loss with the 25fps (speed up) PAL DVD backup. |

Just an update. I re-installed everything. Got a new DIE ANOTHER DISC but same result failted to encode. I do have some new information. I tried playing the m2ts file in VLC and i cant see the video and the audio is choppy and goes in and out constantly. This makes me believe there might be some codec issues. Any clue what codec if any I am missing. I thought by installing all the recommended software with BD-Rebuilder would be sufficient?

If you have any "Codec Packs" installed (they're often at fault) -- get rid of them. Last edited by jdobbs; 26th April 2011 at 14:02. |

Here's an FYI for you jdobbs.....
I've settled on 24250MB as my "custom" size for BD-25 backups. I'm usually at 99% when I load the finished project into ImgBurn "build". If you wave your cursor over the finished folder in Win7, the pop up will usually say between 22.8 & 23.1 GB. VERY consistent! Then I tried the flick "Night Of The Hunter" in 37.04. With that 24250 target, full BU. I got 23.8 GB, which is WAY over! I dialed back to 23450MB (-800MB) & then I got my 23.0, just as you'd expect. For the heck of it, last week I tried it again in 37.07 at 24250 & got the same 800MB over size. There's nothing out of the ordinary on the flick. The main audio is LPCM 1.0, which is all I kept. Let me know if you want any more info. |

@Race Guy, I too use around that size (24300 for me) for my rebuilds. That has worked out really great for most of my "Movie Only" backups, but not all of them. Occasionally it has gone over but if I try to do a " Full" backup, I back it back down to around 24,200 or 24,150. I have never had any go over by more than 1 or 2 hundred megabytes and that was usually on the series type disks where I had to do "Full" rebuilds to get all the episodes. I have always wondered how BD_Rebuilder figures out what is an extra on the series disks because there is no clear cut extra since all the episodes are the same size. I had a series disk recently with five 47:00 minute episodes on it, and a special feature that was 27 minutes long. The first time I ran it thru BD_Rebuilder the original 27 minute extra .m2ts on the 46gig disk was 8 gigs. After the rebuild it still used 3.4 gigs of my 25gig backup, and each 47 minute episode was around 4.1 gigs. I thought that was way too much space that could better be used for the real episodes. I took the all the extras from 3 of the original disks and created a MultiAVCHD BD and ran it thru BD_Rebuilder to create a BD5 disk. The original 8 gig size was squeezed down to just 3 gigs and after replacing it into the original 46gig disk and then BD_Rebuilding it, the size was now 500 MB's. Even after all this it was still good enough to watch. The oversize problem is just when you have lots of extra content to try to compress that gives BD_Rebuilder a problem, and I'm sure if left on the default setting of 23400 it would probably never oversize.
