With regard to generating UHD (HEVC) muxes, unfortunately any muxing application that relies on TSmuxer is going to have problems!

The development of TSmuxer ceased years ago, way before the creation of HEVC...

My problem is not the uhd bd structure, I'm not burning a disc but I'm just trying mux files on hard disk.
It seems bitrate has an influence, if I reencode with lower bitrate like 35000 the Effect is less, but still present.

TSMuxer has issues with UHD. It misses recognizing the start of some frames and then buries the frame within the PES packet of another. As a result the timestamps get way off, sync is lost, and you get jerky playback. After TSMuxer creates the structure, the video stream has to be remuxed completely to correct it. I'm working on that for BD-RB, but just haven't had a lot of free time lately.

I've been dealing with DTS XLL/HD-MA tracks, and I'm starting to keep the tracks. Or rather, instructing BD rebuilder to do so on MKV outputs(Keep original audio). I've been noticing that the outputs lose more than half their bitrate/file size(3700K becomes 1500K). Since I don't see BD Rebuilder "Encoding Audio Track", I'm assuming there's another explanation?
I've dismissed it for a few encodes, since i'm sure the difference is negligible. But now I'm curious lol

Keeping the core of an HD/MA audio stream does not require recoding. After the MKV file is created, run it through Media Info to see if the HD/MA audio is still there, or not.

The output file says compression mode: lossy. Nothing of HD-MA.
So, the original HD-MA has redundant audio information? In that when removed, it's unnoticed? Apologies, my current audio system is bordering on analog, and my understanding not much better lol

Each of the high-def (actually a misnomer) audio formats have in their core the base codec, i.e.Dolby Digital 5.1 @ 640k and DTS 5.1 @ 1509k. That is to allow for players, amps, etc. that do not know about the non-lossy formats to be able to play them. That also allows for programs to also extract the core. No idea why BDRB is extracting the core instead of keeping the whole stream.

You have disabled "Keep HD Audio for BD25/Alternate Intact". Which reduces core. It doesn't rerender the Audio.

Since I'm outputting MKV, I didn't think that setting would apply.

Make sure you have "Keep HD Audio for BD25/Alternate Intact" checked on the SETUP dialog. You also have to select (or create) an ALTERNATE profile that has aType set to 2 (intact audio). If those two conditions are met, then both the core and the HD audio will be kept.

Just a warning, though. In creating an MKV the HD and core audio are muxed separately (as two independent audio streams). An MKV doesn't support two audio types muxed as one stream like Blu-Ray does. That fact makes it even more complicated when you go the other way (from MKV to Blu-Ray), since the Blu-Ray standard doesn't support the HD stream without the core.

Output to MKV is Alternate output (non BD)... so the setting "Keep HD Audio for BD25/Alternate Intact" applies.

All right, all right, just because I didn't go into details... Show-off!

Don't be embarrassed. I actually looked at the code to be sure myself.

It's an old trick. A quote from W.C. Fields: "If you can't dazzle them with brilliance, baffle them with bullshit."

Yeah, he wasn't a very consistently happy guy. I also forget about the quote. Are you sure, Penn of Penn and Teller didn't say that? Haa!
