BD Rebuilder Beta - Bug Reports Only

When doing Alt-Movie Only for a normal Blurays, I had been selecting "MKV Container, 1920x1080, Intact Audio" . It works great and I'm happy with the output. Looking at Alternate.txt it has vFormat=5 (where 5=1920x1080). Does it actually resize the video on a normal bluray? I mean, a typical bluray is 1080p, so I would think it shouldn't, but I have to ask. Or does it cause black bars inserted or something to make the video a full 1080 lines for movies that aren't 16:9 aspect ratio or something?

When I do UHD disks, I've been using "MKV Container, HEVC, NO_RESIZE, Intact Audio" which has vFormat=7 (where 7=No Resizing)

Other than h264 vs H265, if I switch to "MKV Container, HEVC, NO_RESIZE, Intact Audio" for all, should I expect the same output for my regular blurays?

1. if the Blu-Ray source is less than 1920x1080 -- yes it will resize it (since 1920x1080 was selected for output). Yes, it will be adjusted (for example if the source was 4:3). But on a Blu-Ray that would be very rare.

2. Yes, using "MKV Container, HEVC, NO_RESIZE, Intact Audio" should produce the same for 1920x1080 sources. But if you run into a 720p or 480/576 source -- they will not be resized, and a 4:3 source will stay the same (without bars being added).

Certainly

b) the AVIDEMUX output (24p exactly) did not
c) ...and neither does the original

The AVS is a text file that will exist in your working folder with the extension .AVS. It is fed to the encoder through AVISYNTH. The AVS for each audio stream will start with "AUD". You can open it with any text editor (like NOTEPAD).

I guess it is time to change it so that the conversion is not done, with a hidden option to do so if desired by the user.

I had deleted the output so I just ran the job again. Here is the text file

#Created by BD Rebuilder - v0.61.25
LoadPlugin("C:\Users\nigel\Downloads\BDRB 06125\tools\nicaudio.dll")
audio=NicAC3Source("00000.track_4352.ac3").TimeStretch(tempo = 23.976/24.0*100.0)
audio = (AudioChannels(audio) > 6) ? GetChannel(audio,1,2,3,4,7,8) : audio
ConvertAudioTo16bit(ResampleAudio(audio, 48000))

so it appears to have (at least attempted to) retime(d) the audio. But in fact it hasn't. The finished stream does lose sync if played in VLC and in the windows 10 house app "Films & TV". The avidemux unretimed one does not; neither does the source.
Would the mediainfo data of source and BDRB output help any?

Can you post your settings? They are the contents of the BDREBUILDER.INI file in the installation folder.

Also, you actually ran the job right? You aren't testing against the pseudo folder from the import? The audio isn't adjusted until the disc reencode sequence occurs. The reason I ask is your statement that BD-RB "re-encoded the EC3 audio without other amendment". The reencode of EAC3 occurs during import (without adjustment for framerate change), not during the actual running of the job (which occurs after the import, and includes framerate adjustment).

Hmm... it should never keep the original audio when there is an audio adjustment to be made. I'll take a look at that. It must miss it somehow.

[jdobbs]

@RetsimLegin

Go into SETUP and uncheck "Do not reencode AC3 (Blu-Ray only)" under the AUDIO options. Let me know if that has an effect.

[Edit] Yep. That's it. I went back through the code and that flag was overriding the "must encode" condition associated with changing framerate. I've fixed it for the next release.

[RetsimLegin]

@jdobbs I'm using it for another project ATM but I will check back on this later to confirm your own findings. Thanks.

[MrVideo]

I want to again beg that DD+ audio not be re-encoded to DD when building a UHD BD structure.

Doing so removes any potential 7.1 audio and/or Dolby Atmos audio.

I just did a test with a 2160p HDR file and had TSMuxer create a M2TS file. Actually I told TSMuxer to create a BD ISO file. I then put that into my Sony UHD BD player. While the player recognized it as a UHD BD disc, it refused to play it. I need to see if a newer nightly build fixes that issue. In the meantime, I took the M2TS file from the ISO and burned it onto a BD-ROM (RE) disc. The player played the file just fine. The DD+ audio was sent to my Denon AVR. It displayed that the audio was DD+.

Thanks, in advance.

[gonca]

Did you actually burn the ISO to a disk or just tried to use it as a "media file"?

[MrVideo]

Burned to BD-RE. I've downloaded the latest nightly and will try again.

EDIT: Nope, didn't work. Will report it.

[gonca]

Try creating a BD Folder instead and have ImgBurn burn that to disc

Good point. I will give that a go.

The ultimate goal was to verify that the Sony UHD player would play M2TS files, in a BD layout, that contained DD+ audio.

So, until BDRB no longer recodes DD+ audio to AC3 when it is within a file that contains 4K video, I have to do the following:
1) Do a backup of the desired 4K files.
2) Use tsMuxer to remux the DD+ audio from the original source with the BDRB created M2TS file, replacing the AC3 audio.
3) Replace the BDRB M2TS file(s) with the newly remuxed M2TS file(s).

I'm about to do steps 2 & 3. Hopefully all will be fine. Obviously I prefer not to do the manual audio stream replacement.

[MrVideo]

Well, the project in which I was trying to create a UHD set of discs with 4K/DD+ files is now dead in the water until BDRB no longer re-encodes DD+ audio.

There is some kind of subtle difference in the remuxed M2TS file that results in the viewing of the video to terminate early and go back to the menu. I was testing two files onto a disc. I didn't discover the issue until I was playing the 2nd file and chapter skipping. The chapters were created by BDRB, since the original files do not have any chapters. In the case of the 2nd file, shortly after I skipped to the last chapter, it played for a very little bit and then aborted the playing of the file and returned to the menu. IIRC, BDRB inserts chapter marks every 5 minutes.

I know there isn't an issue with the M2TS itself, as I burned the two M2TS files to a data disc and the 2nd video plays thru the location in which there was an issue.

That means this particular project can go no further.

As a side issue, the latest tsMuxer does not like the AC3 file that was created by BDRB. When I placed the BDRB created M2TS file into tsMuxer, it complained about the audio track and left it out of the list of tracks.

[MrVideo]

While working on the above project, I discovered a bug.

The video file contains a boat load of subtitles. I have BDRB set to only include the English subs. But, when I play the disc that BDRB created, pressing SUBTITLE on the player's remote cycles thru all of the subtitles that were in the original file. But, the M2TS file only contains the two English subtitles.

[MrVideo]

Trying to find the UHD BD specification is like trying to find a microscopic needle in a haystack.

[gonca]

BDRB inserts chapter marks every 5 minutes.

Actually, that is a tsMuxeR default setting.

[MrVideo]

Thanks for the clarification. Makes sense, since BDRB uses tsMuxer.

[gonca]

MrVideo
Run a test for you
Took a decrypted disc on local drive
Demuxed all streams (video, audio, subs, chapters, etc)
Re-encoded video
Used tsMuxeR (latest of the day) to mux into UHD structure
Then imported into BD_RB to create menu (quick author)
Burnt to BD-RE and tested on Sony UHD player
Plays fine
.....................renamed tsMuxeR so that BR_RB used latest(at time) tsMuxer(4k)
