BD Rebuilder Beta - Bug Reports Only

[jdobbs]

I have updated the first post of this thread with a link to the latest version of BD Rebuilder (v0.61.21). Changes for this release:

- Corrected an error in which BD-RB assumed
  that all imported HEVC video files were UHD
  regardless of resolution or attributes. Now
  UHD will only be assumed for 2160p sources.
- Added a new hidden option NVENC_DECIMATE.
  If set to 1, HW decimation is accomplished
  for IVTC when using NVENC (rather that 
  forcing use of [slower] AVS for input).
  Works well and fast for repeated frame type
  telecine but not-so-much for other types.
- Corrected a sizing error that can occur when
  importing and reencoding with NVENCC.
- Modified the parameters by which decision is
  made to use original imported file as input
  during encoding of PSEUDO structure.
- Fixed an issue in which including a filter
  that only affects audio was still forcing 
  --avs encoding mode when using NVENCC.
- Fixed an issue in which the GOP keyint might
  be set incorrectly in some circumstances.
- Added a safeguard that gathers the total #
  of frames encoded and compares it to that
  expected -- meant to catch premature NVENCC
  termination that doesn't return an error.
- Corrected an issue in which imported files
  with non-compliant framerates, or certain 
  types of conversion actions, might encode
  at an incorrect framerate when using
  NVENCCC.  It might also cause TSMUXER to 
  error during rebuild due to a frame rate 
  mismatch.
- Added code to use UHD clips for blanking
  when working with a UHD source.
- Added code enabling NVENCC to be used for
  non-compliant source conversion during
  import. This method is experimental and
  can be enabled by adding a hidden option
  NVENC_CONVERT=1 to BDREBUILDER.INI.
- Updated TSMUXER4K to the 2021-02-08 build.
- Other minor corrections and cosmetic fixes.

Okay. As a part of the update I posted today, I've also included a new function that I'm keeping hidden so that only those users (this forum) who do true beta testing can try it out and (hopefully) help me get it fully functioning. The function is conversion of non-UHD discs to UHD format (v3 with HEVC encoding).

Here's what works now when it is enabled:

1. Performing a Movie-Only backup from a non-UHD disc to UHD format.
2. Converting an imported pseudo-disc structure to UHD format (full or movie-only).
3. Converting a disc that has been Quick-Play authored to UHD format (full or movie-only).

Here's where I'm having trouble:

- Converting off-the-shelf commercial blu-ray discs to UHD format via full-backup mode.

Obviously something is not being updated correctly when I create the UHD output from a commercial disc -- something that doesn't exist in the simple menuing system associated with BD-RB internal authoring. But I haven't been able to put my finger on it. I'm hoping some of the folks who are familiar with UHD and (maybe) those who might have a copy of the BDEdit program that supports UHD can look at the output and help point me to where the issue is.

To enable the UHD conversion/output mode, add the following hidden option to your INI file:

UHD_CONVERT_ENABLE=1

When you have added this option, a new menu item will appear on the SETTINGS/OUTPUT OPTION menu called:

"Convert BD to UHD-BD (HEVC) Format"

As long as it is checked, all output from BD-RB will be in UHD-BD format.

Please note that the UHD standard only supports 2160p and 1080p formats for HEVC encoding. So only 1080p formats are converted to HEVC by default. In testing, however, I have found that (at least on my UHD-BD player) other formats (like 720p and 480p/576p) will play just fine if I convert them. I've been very pleased with the quality I've seen using HEVC on imported DVDs in 480p format (you can fit A LOT on a BD-25!) So, for those who want to live on the wild-side, I've added another hidden option that enables conversion of non-1080p sources into a UHD formatted disc as well. To enable that mode, just add the following to your INI file:

UHD_ALL_MODE=1

I hope testing will reveal where I'm missing the boat on standard commercial BDs and I can get that working for the next release.

Thanks.

I don't know if this is a bug or just me doing something wrong, but here goes.
I've just done UHD backup (BD25, Movie and Menus (Auto blanking)) of The Greatest Showman (Nvenc), all seemed to go well, until I played the burned disc in my standalone player (Sony UBP X500).
The movie itself plays flawlessly, excellent PQ,
however the menu stutters.
Upon investigation it seems that the two m2ts files that make up the menu video were not processed by BDRB but just copied across intact.
MediaInfo reports that these files are 85Mb/s (Max 109Mb/s)!
I tried to investigate why these files were not presented in the BDRB stream list and it seems they only appear if I select DVD 5 or 9, but BD25 or over and it ignores them.
Am I right in thinking that these files have too high a bitrate for BD25?, or did I dream that?
Any help is appreciated

Does this mean you are getting closer to having the ability to make UHD discs from scratch with 1080p/2160p H264/H265 TS/MKV files?

It can do that now. You have to set the hidden setting to do 1080p. 2160p works either way. You just import them first -- and then reencode.

If you want 1080p output to UHD/HEVC you have to set UHD_CONVERT_ENABLE=1 and then select the UHD-BD option under SETTINGS/OUTPUT OPTIONS.

Note that any created menus will still be AVC and 1080p -- but that's compatible with UHD-BD. I may add UHD menus as a future option as well.

Try adding the following to your INI file and see if it reencodes the menu:

MIN_M2TS_SIZE=0
MIN_PLAYLIST_MINS=0

There is definitely a difference in allowable speed between a BD-25 and a BD-66 or BD-100. But I've never actually had an issue because of it. But, hopefully adding those two hidden options will reencode the menus so you can see if that is the issue.

Thanks, Somehow I must have missed the announcement that it was working.

I already have those two items in my INI files.
There's something else going on here - I'll investigate further

Here's a "testing" option I'd forgotten about:

REENCODE_MENUS=1

Try that. But, be warned, I don't think I've ever tried it with UHD..

That did the trick, perfect
Thanks

Did it play back correctly without issues? I so, I may want to consider making a complete reencode the default when outputting UHD to BD-25/50.

[CraigWally]

absolutely correctly, no issues whatsoever

Thanks kindly Boss, that is awesome!

It's definitely past time for a contribution, I would assume still by way of Amazon card, right? (although I believe MrVideo said something about you like us to send Strippers directly to your house now...? Did I get that right?)

BTW, I'm really glad you addressed this following issue because I know that gonca has been suffering from it for many years:

"Added a safeguard that gathers the total #
of frames encoded and compares it to that
expected -- meant to prevent premature termination"

You came back after all this time just to make a juvenile joke.
Put the mask on a little tighter
