Thanks for the clarification.

And everyone , still the same
3840 x 2160 pixels..
It takes around 15mins on my geforce gtx 1070 card , to make then fit on a BD50 ..I also use BD Rebuilder , to Alter the build of the disc as well , resulting in resizing a lot less .

You may also want to take a look at rigaya's NVEncC. It is continually developed and well documented.

Open playlist on tsmuxer, you will figure out 2176p.

This is incompatible with Xbox One S and X player.

Based on the reference, it looks like 2176 is it, period. The hardware is only 32x32. Sounds like Xbox needs to get it right. It is the same issue with 1080. It is encoded to 1088 (16x16) and set to display at 1080.

Yes, tsmuxer reports 2176p, but mediainfo says 2160p... after reading the discussion at nvidia I would trust tsmuxer. BUT it's an old discussion and in the end they say the Turing (for those who don't know: GTX1660, 2060, 2070, 2080 etc...) cards have HW capabilities of 8x8 and 16x16. So off to buy a new gfx card then

Anyway, even though an dvdfab encode have 2176p, I believe they have gotten around the problem with green screen on the XB and also works flawlessly for most others. So what I'm saying, not to get too much OT, is that jdobbs can also fix these problems when/if they occur with bdrb.

I did my testing with Staxrip, which makes use of NVEncC.

BD Rebuilder v0.61.05

I have updated the first post of this thread with a link to the most recent version of BD-RB (v0.61.05). Changes for this release:
Code:
- Corrected an issue that could result in
  blocky or distorted display during FF or
  REW on full backups.
- Fixed an issue in which an imported source
  (very rarely) might not have its frame rate
  detected by MEDIAINFO.
- Added an "*" to the "HEVC" callout of the 
  stream display for sources that have HDR and
  "**" for those that also have Dolby Vision.
- Changed the setting for adjustment/scan of
  MKV during import.  Should have been off by
  default instead of on.
- Updated prediction routines for CRF encodes
  to more accurately predict UHD output when
  CRF is selected.  Still needs testing.
- Updated TSMUXER4K to a more recent nightly
  release.
- Other minor corrections and cosmetic fixes.

The “Corrected an issue that could result in blocky or distorted display during FF or REW on full backups.”
was a TSmuxer ou BdRebuilder bug ?

Because with this last version the problem is fixed. And now UHD backup is perfect.
But before I had same issue using only Tsmuxer.
Now subtitles/audio in GUI replacement is what I miss

The one mentioned in the log was a BD Rebuilder bug. Not sure if there was another bug fixed in TSMUXER. If so, I wasn't aware of it.

BD-RB encodes 4K import without HDR in HDR. I tested this with a x264 4K mkv file.

Since 61.05 BD-RB uses higher bitrates than 35Mbit on UHD rebuilds. Is this normal?

For me this is a feature and not a bug.

Yes. I originally left it at the maximum for a standard BD while I was testing it (to be safe). But, after some testing, I've now increased it since a UHD BD-25/50 has a higher maximum bitrate.

Just remember, though, that this is just the maximum bitrate (associated with peaks). The actual bitrate for VBR is typically much lower (unless the source is small enough that it reaches the maximum with the selected target).

Wow. I'm really confused as to how it could get caught using the same CRF value that many times during prediction??? I'll look at it.

Can you post your REBUILDER.INI file?
