A 264 extension implies H.264, which is AVC not HEVC. Unless something has changed recently of which I'm not aware, Bluray does not support 3D in UHD (3840). The resolution has to be 720p or 1080p.

Here is an explanation of what I'm trying to do.

There are some 3D releases lately that have been formatted as full side-by-side, meaning the video frame is about 3840 x 1080 (or thereabouts). These videos play fine with full resolution, but are not supported by many players.

So the idea is to convert these full SBS into MVC files, which are supported by quite a few players, or even converting them to full 3D Blu-Ray format (BDMV folder or ISO) and maintain the full resolution of the video

While most of these videos are already encoded using H264 CODEC, when they are being imported into BD rebuilder, they are seen as UHD video sources due to their size. BD Rebuilder also recognizes the fact they are side by side and demuxes and re-encodes the streams using H264. The resulting files are VID_xxxx.264, VID_xxxx.mvc, and of course audio stream xxxx.track_xxx.ac3 or xxxx.track_xxx.dts.

So far so good. But then it tries to mux the files and fails with "Can't open file: ..\WORKFILES\VID_00000.AVS.hevc". That's because it thinks this is somehow still a UHD/4K encoded in H265/hevc. So this was the first problem: BD Rebuilder's getting confused about what the file extension of the output should be: It creates the right kind of stream, but during muxing it looks for the wrong one.

So the workaround is to grab the stream files and manually remux them using TSmuxeR and have it output to a ISO file. In the past that worked fine. But now I have another problem. The resulting Blu-Ray ISO or the individual M2TS files do play in 3D, however, while the left eye is clean, the right eye frame contains a lot of blocking and pixellation as seen in those images I posted previously.

Those images I posted are indeed from the frame packed video, but I used Stereoscopic player to show them side by side so that the problem can be seen. When playing this in real time on a 3D TV, that pixellation makes the video unwatchable as it happens almost constantly when there is motion in the video. I even ripped the video back to MVC using DVDFab, but it has the same issue.

Hope this clarifies my problem.

Yeah. It's probably the 3840x1080 source that's confusing BD-RB... the 3840 width makes it think it's working with UHD (implying HEVC). Not sure whether I can do anything, but I'll look at it.

[Dudeman007]

Is there something that can be added like a "UHD-BD = 0" switch to prevent this from happening?

Also what about the bad artifacting issue? What's causing that?

P.S. If you want me to, I can upload a 4~5 minute snipped of the source SBS file so you can try it yourself.

Whoops, I accidentally posted this in the Feature Requests, sorry about that...

Here is what I was asking:

I THINK there is a way to change the playlist when using BDRB, but I forgot what it was.

Basically, I have one of those really rare Blu-rays that when you do a full disc backup and you 'Blank' the main movie in order to create just an Xtras disc, it blanks everything. It's also one of those annoying Blu-rays that divides the main movie up into many m2ts files.

Now, I've already used BDRB thankfully to gather all the stupid main movie files and rending them to a normal playable Blu-ray. But, when I went to create an Xtras only disc, if I Blank the main movie, everything is blanked. IIRC this has something to do with choosing a different playlist, right?

Is that possible?

Also, I generally try to keep the menus and such intact for just the Xtras, is that possible to do?

Thanks!

[Lathe]

Anybody...? Sure would help to know how to choose the right Xtras playlist if that is possible.

Thank you!

I'm not sure there is ever a single playlist for all the extras. All of the discs that I remember watching has a menu listing the extras. During a submenu there is a potential for a play all; for example the making of series of featurettes or a bunch of deleted scenes. I've never seen a play all for every extra.

Thanks man, I appreciate the reply. It's just the rare, odd Blu-ray that for some reason when you blank the main film so that you can put all the Xtras with the menu on another disc, it just blanks everything. I had THOUGHT there was a way to go in and change that (don't know why they make it that way OR why they divide the movie up into several smaller files) It's a fairly rare case, but once in a while for some mysterious reason I guess they just make the Blu-ray that way.

I can always just import the xtras and create a Quick Play menu, so it's not THAT big of a deal ultimately...

Splitting is done for a couple of main reasons:
1) extended version/theatrical version
2) different language text in different areas of the movie (Disney has done it with opening and closing credits where the text is in the language requested to be played by the user. But the rest of the movie is the same.)

Branching allows them to put both movies on the disc and have the highest bit-rate possible.

I've also seen it as a version of copy protection. When copied, the film's software detects this and plays a different playlist, resulting in some pieces being played out-of-order and sometimes, ultimately, displaying a notice that the disc was a copy.

Yep, when they're is branching I see why they need to do that, but this would have to fall into the last case you mention, some form of supposed copy protection I guess. And, maybe it's related to that or not, but in this case the weird blanking the main movie file with BDRB blanking ALL the files. Strange...

[MrVideo]

Ya, jdobbs is going to have to respond as he programmed the "blanking" code and knows the logic behind what it will, and won't, keep.

I had in the past some small succes with the hidden option REENCODE_MENUS=1

[Emulgator]

I can only suggest to use DGDemux and BDEdit at the same time on the same BD rip.
In DGDemux go through all .mpls and visualize what is happening in each playlist.
Make notes of all the assets (I do that in an Excel spreadsheet for every serious project).
In BDEdit go through the controlling .mpls. Pick one, add .m2ts entries, or delete them, shift or shuffle them at your will.
If that plays what you need, have it reencoded by BD-RB.
A hoped-for semi-automatic detection of each one's favourite path under past and today's varying structures... I would not put that on jdobbs.

I was wondering if there might be some hidden option that might help, I'll try that, thanks!

Heh, oh yeah, I can imagine that would work and that YOU would definitely know how to do that!

That's probably a tad over my paygrade, but I appreciate the input. Usually I just end up doing a super fast whole disc encode and use that for the Xtras. Thanks though!
