BD Rebuilder Beta - Bug Reports Only

[drjake]

I understand that there is not a re-encoding going on. I was trying to use BD Rebuilder to do a movie only BD-25. I have checked off Stricter AVCHD compliance. The problem is that the BD-25 backup is not working with BD-Rebuilder. The files that it is producing do not create a working blu-ray disk. I can do it the more difficult way with TSMuxer but I am trying to figure out why I can't do a BD-25 with BD-Rebuilder when I have been able to do it in the past.

Looking at your posted log, there is not a reencoding taking place, since the original is less than BD-25 size. If you want to reencode this movie, try setting the size to BD-9 or BD-5. Movie only will look great for BD-5, but your choice if you want BD-9.
All BD-RB is doing with your current settings is demuxing/remuxing and rebuilding, all still with the original codec. (VC-1?)
Depending on if you have selected Strict Compliance for movie only AVCHD, Auxdata, BDJO, JAR and Meta will either be present or not.
Or:
With tsMuxeR GUI, either select AVCHD or BluRay. The files will be there or not accordingly.

BD-RB only uses tsMuxeR to rebuild the same way tsMuxeR does when using the tsMuxeR GUI. So I doubt the problem is BD-RB. You can try both with and without Stricter AVCHD compliance, but I believe if you are using BD-R/RE media, use BluRay setting.

Hello everyone.
I've been made about 15 bluray and I had no problem except the following:
let only the ENGLISH and SPANISH audio and select all the subtitles on Bdrebuilder options
But when watching the movie with SPANISH audio on, for more than select subtitles off, subtitles appears...
and the truth that is annoying ... any ideas what might be the problem... and what the solution? thanxs!

BD-RB never defaults subtitles on. It's probable that your player is setup so in a way that causes them to be activated.

thanks for the reply jdoobs...Use the PLAYSTATION 3 as blu-ray player ... I just finished 007 Casino Royale ... I try the original , select SPANISH audio and the captions do not appear ... instead I try the copy and subtitles appears... I believe that it isnt an issue of the PS3 ... There is something in the program that makes the captions go whenever another language is chosen than the English ..what do you think could be the problem?

Maybe it's not a bug, but I am wondering about the initial value for crf prediction for the same file and same settings and same target size (BD9).

Full backup mode:
- [21:07:18] Reencoding: VID_00009 (4 of 95)
- [21:07:18] Collecting video information
- Video: 1920x1080, 23.976fps, 2'510 frames
- [21:07:18] Performing CRF Prediction...
- Analyzing 17.91 19.18 18.79 [18.88]

Movie only mode:
- [12:47:13] Reencoding: VID_00009 (2 of 26)
- [12:47:13] Collecting video information
- Video: 1920x1080, 23.976fps, 2'510 frames
- [12:47:13] Performing CRF Prediction...
- Analyzing 58.13 10.00 46.66 37.93 31.49 26.81 23.50 21.16 19.55 18.55 17.92 17.68 17.46 17.24 17.08 17.18 17.14 17.11 [17.10]

Why is the initial crf value for "movie only" 58.13, (continuing with large initial swings)? It looks strange to me, because I would have expected it to be lower than for "full backup" mode as there is more space available for movie only (which is eventually confirmed by the final value of 17.10 vs 18.88).
I noticed this "oddness" of the initial crf throughout the disc for most of the segments and for other discs as well.
On the positive I like to mention that the final target size was nicely met in both cases - which is the most important of course

It's linked to the new code I added for 720p conversion -- I've fixed it for the next version. I got one that started with a value of 738... and I was very surprised that X264 didn't choke on it.

As I said: It is NOT in the program. I'd have to write code to turn subtitles on -- and I haven't. I can't say whether it is something in TSMUXER -- but I've never seen it reported anywhere. I've also gotten no other reports of an issue of this type in BD-RB other than yours.

Sorry, but that pretty much just leaves your PS3... whether "you believe" or not.

Is this a full backup or a movie-only backup?

[EDUDE]

always full backup... TERMINATOR - 300 - BATMAN the dark knight to mention a few... on HIGHT QUALITY, others on HIGHEST.... coulde it be a codec problem instead?

[tekmobile]

Just got an error anyone know what it means

[02:22:06] PHASE ONE, Encoding
- [02:22:06] Extracting A/V streams [VID_00000]
- Error in attempt to extract audio/subs.
- AV frame too large (55814 bytes). Increase AV buffer.
[02:22:38] - Failed to retrieve audio, aborted

I've done 300 and Batman (Region A) and I don't have any problems...

I can't imagine how it could be a CODEC issue... the subs are an overlay. There is a register in the player that gets set when a graphic overlay (subtitle) is to be displayed. Somehow the register is getting set -- and only a command sequence or the player itself can set it. The command sequences from the original disc aren't touched when a backup is made by BD-RB, they are kept completely intact.

Something has to be turning it on in your player (PS-3).

[EDUDE]

Thank you very much jdobbs for taking care of the matter ... i will check the configuration of the PS3 and see if i can find a solution!

@jdobbs

This may be a silly question: Why is BD Rebuilder muxing the re-encoded .264-file into an .m2ts-file first before making the final muxing (movie-only, mkv_intermediate=0)?

Wouldn't it be possible to do the final muxing *directly* with the .264-videofile?

Sorry if this has been discussed before..

Thanks for the continued updates for BD Rebuilder, it is a great piece of software and I have backed up many of my blu-ray collection without any problems.
However there is a series called Torchwood here in the UK and the blu-ray's for both series 2 and 3 fail to compress to BD-25. Is it because there is simply too long a duration of video on the original discs?

There are reasons it is done the way it is. Actually, when doing a full backup, the files made are the final M2TS files. In Movie-Only it is a little different.

Length shouldn't have any effect. Normally when this error occurs it means the CODEC is having issues. The best way to see what causes the problem is to open the affected .AVS file (VID_00002.AVS) directly with Media Player Classic or Windows Media Player. In most cases an error message will be displayed.

Is it possible to add an external subtitiles when rebuilt a BD?If not,try to improve with this function would be perfect....!

Hi,

I found that the latest BD Rebuilder version generates problems in video coding during the first roughly 30 secs of movies. If there is mainly a black background (for example during the title screens) this black is more a middle gray and additional blocking errors occur. After this initial phase everything appears to be fine.

I found this problems on both movies I encoded ("Transformers" and "The boat that rocked", both region B) and checked that this does not show up in the original rip. It appears to me like the video coder needs some time to "sync" to the video stream. I have not observed this in previous versions.

Greetings

PS: just saw, that this is still happening at the credits (on black background) .... so it only has to do with the fact that most of the picture is black. I am going back to 29.04 and hope for the best ...

The version of BD-RB probably won't make a difference -- since X264 is actually doing the encoding. Before going back, I'd look at the original -- you may see that it is where the issue is.

This gets more interesting. I did a BD9 backup of Coraline and it works fine. However, if I do a BD25 (don't worry, I am using a BD-RE to experiment), the disc will not play. However, if I run the m2ts file through TSMUXER again (using tsmuxer GUI), I am able to create a working BD25 disc. This leads me to believe that there is some bug in BD-Rebuilder that affects BD25 backups.
