BD Rebuilder Beta - Bug Reports Only

[MrVideo]

THD must have an interleaved ac3 core file for BD compliance.
MKV cannot store two interleaved tracks, so it splits them.
Stores them as a thd track and an ac3 track.
Yep, know all that. But, MediaInfo only shows the THD track. The AC3 core appears to not have been stored with it. I'll just have to get around it another way. Oh well.

[gonca]

MKV cannot store an ac3+thd track.
It has to separate the core from the thd, creating two separate tracks.
THD tracks in MKV are never BD compliant

[MrVideo]

It has to separate the core from the thd, creating two separate tracks.
As I noted, there was only the single THD audio track. No separate AC3 core track.

It would have been nice if BDRB would have indicated what it was doing. But, the point is moot as I've scrapped working with the particular file.

[Lathe]

Have you tried "Run as Administrator"

Yep, I tried that...

Thanks too to the other suggestions about the AV software, but I haven't changed anything that I am aware of. I'm still running Avast and AdAware. I'll try defeating those first and then try to run BDRB again, although I'm not getting any warnings or prompts.

[Lathe]

Heh, Bro, I swear it seems like you keep asking about this in different ways :) As I have suggested before, the solution is very simple. Just run UsEac3To, drop in the MKV file with the TrueHD track (which as Gonca says being muxed in MKV format the core is missing) and then choose as your output TrueHD+AC3 and then run the command line and it puts the AC3 core back in. THEN you can take the resulting file which now is compliant and simply add/mux it into BDRB.

[Lathe]

Yep, it's Avast. In the notifications it is saying it quarantined BDRB.exe because it has 'FileRep malware' I hafta figure out how to make an exception. It's never done that before, I wonder why it is doing so now...?

[MrVideo]

Just run UsEac3To, drop in the MKV file with the TrueHD track (which as Gonca says being muxed in MKV format the core is missing) and then choose as your output TrueHD+AC3 and then run the command line and it puts the AC3 core back in. THEN you can take the resulting file which now is compliant and simply add/mux it into BDRB.
I don't remember seeing this trick mentioned. I'll try and remember if I run into this again. I've decided to go into a different direction and have decided not to deal with this file at all.

You are trying to encode a non compliant track.
Merge the thd and ac3 tracks together or re-encode an ac3 core into the thd track.
Or wait while BD_RB does it

:) :rolleyes:

[MrVideo]

As in previously mentioned before this current discussion.

[CraigWally]

After a movie-only backup using that option it appears to me the 3d output of my BD rebuilder has artifacts(video pixelation)
That will be with a software player? Yes?.
Burn it to disc and play on a standalone player, trust me it will be fine

[Mark_Venture]

So I've got bluray I'm trying to back up which BD Rebuilder gets the following error:

BD Rebuilder experienced and error 2503 [09:11:07] SourceCheck() 00006 2503

followed by:
Selected source is not BD format.

BD-Rebuilder.log has:
- [09:30:38] SourceCheck() 00006 2503

The disc is John Williams Live in Vienna, Wiener Philharmoniker - Anne- Sophie Mutter. from 2020. Purchased via Amazon, and says "all regions".

I tried using passkey and makemkv.

The original disc plays in my bluray player just fine.

EDIT: What info can I share to help with this?

[Hooman]

That will be with a software player? Yes?.
Burn it to disc and play on a standalone player, trust me it will be fine

After lots of experiments, I found out it's a problem with Frim decoding/encoding because when MVC to AVI Converter + AVFS + CineVision MVC Encoder + setting "REBUILD_COMPLETE=0" + replacing ESs in Workfiles + re-rebuild are used there's no such artifacts.

Update: The software players such as PowerDVD 19 and WinDVD only play the 2D version (no artifacts when encoded with CineVision MVC Encoder) and my standalone Samsung Blu-ray 3d player doesn't start playing the BD-Rebuilder 3d clips, but when the same re-encoded MVC videos are re-authored in Scenarist BD (SSIF format) all of those players display the 3d effects perfectly (there's no viewable difference between the re-authored 3d BD-25 and the original 3D BD-50.)

[bjones]

This is probably an easy question for the experts here. I'm trying to create alternate output mkv's from my bluerays in HEVC for some size efficiency. Using the mBitrate along with vBitrate seems to have no effect and it encodes as a constant bitrate at the vBitrate setting. On the same settings except as AVC it works as expected with an avg bitrate close to the vBitrate setting and a peaking bitrate exactly at the Mbitrate setting. Is it another setting I'm missing or is mBitrate not supported on HEVC encodes ? Encoder is the nvidia one in the distribution. Thanks for any pointers

[Emulgator]

If one is used to control x264, then x265, then uses NVEnc:
Bitrate control is different within NVEnc (both 264 and 265), so some parameters have to be translated, some ignored.

@jdobbs When reencoding seamless branching titles with Dolby Vision, not all the segments are reencoded using "VID_00XXX.CHP" for proper DV compatibility, mostly smaller segments:

Use NVENCCRE.exe, as you can resize the output to 1920x1080.

Thank you I find it but I notice this tool not let me to choose de crf or pass

[jdobbs]

Just a reminder. You have to have a compatible NVIDIA video card to use NVENCCRE.

You can do the equivalent of CRF but it's called "Constant Quality". As for "pass", the NVIDIA encoder only does 1 pass encoding. They have a mode they call "two-pass", but it doesn't really meet the definition of a two-pass encoder.

Hi Jdobbs I have an Nvidia, and I have to say it I really appreciate your work buddy, first was Dvdrebuilder and next BDrebuilder, I follow you from years and Thank you

If you let me to ask you, the only problem that I have with Bdrebuilder is when I try to encode from 4k to 1920x1080 intact audio, the result still 4k is there one possibility that you can fix it?

[MrVideo]

I have an Nvidia
That does not mean it will work. Did you go back thru the posts and read the discussions about the nVidia models that will work?

You would just set the output size to 1080p.

It should work with BD-Rebuilder too. I'll have to do a test and see.

Oh! The good ol' days of BD Rebuilder when I would drop in here even before checking my email, lol. I was messing around with doing a 3D movie only encode and it seems it worked, log even shows MVC encoding. When I played it the 3D seemed flat but it is 3D cause it triggers my 3D glasses. Is there some trick I'm perhaps missing. I really need to do a quick play or a movie only because the menu and play selections are on a Japanese import 3D with Japanese text.

Also has anyone had any success with doing 3D Mkv's?

[SuperFist]

If you have a compatible NVIDIA card, you can use NVENCCRE to so the encode.

jdobbs, I'm embarrassed to say that I didn't even realize BD-Rebuilder could do this!!! :(

For years I've been using CloneBD just for this purpose only for it to be plagued with artifacts and me learning to live with them.

Early this morning, I converted Troy: Directors Cut (2004) and experienced such pixelated artifacts with CloneBD and thought there had to be another program that could deliver better results. Then I remembered how much better BD-Rebuilder did than DVDFab when I was created BD-Rs and I searched this thread for creating MKVs and sure enough, I struck gold! :D

Once again, amazing quality for an amazing product... and it's still FREE!!! :eek:

So thank you, sincerely yet again, my friend! You are the hero we all need right now.

BDR v0.61.28

[MrVideo]

I just discovered an issue with the NVENCCRE program. When recoding HEVC 2160p material, it goes from constant frame rate to variable, with the listed frame rate as 23.976. That doesn't happen when BDRB rebuilds 2160p. Is there a reason this is happening?

UPDATE: Nevermind. The issue was caused by ffmpeg, which I used to re-wrap the mkv file to mp4.

[Mike-uk]

is tone mapping possible with BDRB ?? so got a 4k mkv with hdr, i want a sdr version for bd25 , thanks

Hi Everyone, included a twisted Hello to Lathe,

Is MULTIPROCESS=1 or any higher number broken when a GeForce RTX 3060 is added to the System? The Speed is of WOW/Amazing...when using nVIDIA Enc.. Same thing you commented so long ago when you got a hold of a FAST GPU, JD,. I've been looking and holding on..

So, anyway, I want to check the CPU, not GPU, but MULTIPROCESS which seems not functional when this new board is active. I discovered with my older board all I had t do was rename PSEUDO in some way from an Import item.
Any Insights by anyone?

I'm still having trouble with the issue I reported a couple of years ago regarding subtitles when compiling a disc with multiple UHD titles. I've noticed that when I open one of the playlists in tsmuxer that is generated in the IMPORTS directory, it looks fine, but the playlist that is generated in the final recompile seems to introduce the problem. When viewing one of the final playlists in tsmuxer, the subtitle streams are unchecked and in the status window a "#" symbol appears to the left of the subtitle stream info.

I'm curious as to why?

Having a Ryzen 3600 for a long while now, and a new RTX 3060 I wanted to know what the speed differences are. As well as quality.

--

JD and everyone:

I've been enjoying the quality of NVENCCRE, as well as BD-RB's version of it and better ability to control the filesize. After encoding some Blu-ray movies (single files) to a smaller size (8GB) I decided to make a Blu-ray. Several movies on 1 BD-25/50. When importing I noticed that output disc didn't play correctly.

Each movie would start fine, but chapter skip resulted in move restart.

If I create a BD from BD source or older rerenders (Using BD-RB)... zero problems.

Anyone else come across this?

[musiclover]

Is it just me or is it all of us but are you not reporting it?
When rebuilding a bluray the log window fills up to a point and then stops filling up. The file BD-REBUILDER.LOG keeps receiving updates however. It is no biggy, but I thought I'd mention it so it can be handled if it's all of us having this issue.

[AmigaFuture]

What was the output container?

MKV only. (For several years.)

[MrVideo]

OK. Did you look at the MKV file with MediaInfo to see if the chapter marks were there?

[MrVideo]

Is there a way that the NVENC program can be told to create I/IDR frames at chapter marks? With the x264 encoder, that is done with a filename_qpfile.txt file.

When creating BD discs, you really want the chapter marks to land on I/IDR frames.

Thanks

ThanksI'll have to go back and check, but I would have assumed that setting a chapter mark would automatically trigger an I-Frame.
