I'm away from my office right now for a week, but I'll do some tests to see if I can repeat the issue when I return. |

There is another simple way to make the sync? I have also the subtitles on my mkv! @MrVideo What you say is correct: on the blu-ray associations are not present 1280x720 25p but also not present 1980x1080 25p. but i have many blu-ray working properly with 1920x1080 25p. thanks |

Hi
I have try to make blu-ray using tsremux (using blu-ray filder option) and this create blu-ray 720p 25fps that work properly. (I have burned this to bd-re and play correct on blu-ray player and ps3) after this I have used bdrebuilder to import BD(s) function and the result is perfect 720 25p blu-ray working now the "problem" is i need to make blu-ray whith many episode and many season and this is very complicate to make this process. there is a possibility of "fix" bd rebuilder, with Calm of course? thanks again Last edited by zorro101; 6th August 2017 at 10:50. |

I use bdrebuider file-> import function for make "authoring" blu-ray (i need to create blu ray for season series) i dont know why bdrebuilder import have different behavior 1) file-> import-> mkv,m2ts,etc 1280x720 25p -> audio sync loss (because bdrb change fps to 23.976) 2) if I put mkv into tsremux and make "bluray folder" and after i use bdre -> file-> import-> BD(s) -> work properly (without change fps) thanks Last edited by zorro101; 6th August 2017 at 12:42. |

After you import the MKV files and configure the menu, DO NOT click on the Backup button. Just go into the working area and burn the BDMV/CERTIFICATE directories onto a disc. Running the Backup process is where the 25 fps -> 23.976 fps is done. Only import enough files to fill a 25GB disc (or a 50GB disc). |

all my test descript are only with menu creator. and i can add that the backup (for compression) is not a problem. i tried to make 5 episode as descript (creating bd from mkv 1280x720 25p with tsremux and after import on bd-rb as multiple BD(s) ) this produce prefect menu with 5 episode and all 5 episode are 1280x720 25p. i have burned and perfect reproduct on blu-ray player, but i also test with bdedit and all 5 file are marked as 1280x720 25p. after this i have tryed to compress the result with bd-rb and any file are processed, correctly, as 1280x720 25p. i repeat, the only "problem" on bd-rb is the import function whith file 1280x720 25p from container mkv, ts,m2ts,etc... thanks |

23.976 is available in regions B and C. Does that make it "PAL?" |

Interesting that you say that. NTSC/PAL are old analog specs that so many are trying to apply to the digital world.
Interesting note for both NTSC and PAL is that both are COLOR specs, added to the existing B&W broadcast standards. NTSC does modify the existing 30 fps B&W spec, to get 29.97 color to work (even though color would have worked @ 30 fps and we wouldn't have this 29.97/23.976 mess) and PAL added color to the existing B&W 25 fps. In other words, the broadcast specs for 30 fps and 25 fps came about long before NTSC or PAL. And none of the broadcast specs include 23.976/24 fps as broadcast frame rates. They include specs on how to handle said frame rates for broadcast (not part of NTSC or PAL). |

That said, I suspect that jdobbs will "fix" it so that 720p @ 25fps and 1080p @ 25fps are not available in the final output because both are not part of the Blu-ray spec. But, maybe the conversion to 23.976 could be done in the "Backup" portion of the process, leaving the original files alone during the processes before that point. And/or, during the "Backup" portion of the process, the 720p could be converted to 50 fps (frame rate doubling) and the 1080p converted to 1080i @ 25fps. I suspect that AVISynth has filters to be able to do both. That will allow the time spectral info not to be lost. Just a thought. Last edited by MrVideo; 6th August 2017 at 22:49. |

Hey jdobbs,
@videofan3d has made a nice little appliciation to keep 3d offsets for subtitles intact after reencoding with FRIM. The tool is called h264offset3d and can be found in this thread: https://forum.doom9.org/showthread.php?t=174563 Any chance you could integrate this in BDRebuilder?? Then we would be able to make perfect backups of 3D discs. Two additional steps would be required: Before reencoding, the original offsets need to be extracted and after encoding they would need to be reinserted. As h264offset3d is command-line based I think this could be intergrated in BDRebuilder's workflow without too much work?? After reinserting offsets muxing can start and in this step, the subtitle streams need to be flagged to the according 3d plane as on the original disc. It would be nice if we could also choose the used flag manually (as in TSMuxer). Any chance you could take a look at this and intergrate h264offset3d in BD Rebuilder?? Would be great, thank you very much |
