View Full Version : How to update Blu-Ray indexes/structure

I'm primarily interested in BD50->BD25 conversion. Whenever I do this, I want to avoid encoding the video, so preferably I want to remove the extras and all languages other than English.

For clarification, there are two methods:
1: Stripping extra's and unwanted audio streams
2: Encoding video's

Having said this, when I use method 1 i face the problem of this topic. The problem refers to the stripping of unwanted audio streams. For this I use tsmusergui. I open the .m2ts of the main movie, I deselect the unwanted audio streams, and as output I select "M2TS muxing" and I start the muxing. After this I take the exported .m2ts, and replace it with the original movie .m2ts.

When applying method 2, I used BD Rebuilder. It reads the original BLURAY structure, encodes the video, and creates a new directory and there it places the encoded video in the original bluray structure.

Hereby it somehow adjusts/updates the indexes/structure information of the bluray. Because when I use method 2, it is totally fine. But when I use method 1, the bluray work correctly. When I play the rip (ofcourse after I created an image of it, and mounted it) in PowerDVD, it starts up fine. But when I click 'Play movie' in the menu, it screen turns black. In the timeline in the bottom of the screen i do see the correct playback time of the movie but the screen stays black.

So, from my point of view, BD Rebuilder does something with the original structure of the bluray, and adjusts this to the modified .m2ts. This would explain why my rip using method 2 would work, but does not work using method 1.

So what I want to know is how to make my rips work using method 1, so how can I update the original bluray indexes/structure to make it work with my stripped movie m2ts. Is there a tool which could fix this for me?

Thanks in advance!

Simply choose "BluRay Disc" as your output type in TSMuxer. Transplanting .m2ts files will not work just as transplanting VOBs into a DVD structure does not work. Just like with IFO/VOB, BluRay discs have a MPLS/M2TS relationship. Choosing BluRay Disc output will make TSMuxer create new .mpls files which will result in a working BD25.

When stripping your m2ts file, create a new blu-ray structure with tsmuxer. Then when replacing the "xx.m2ts" file, also replace the "xx.clpi" with the new created in tsmuxer. Remember to rename "xx" with the original number that you are replacing...

Now that sounds promising!

I'll try this and i'll get back to you. :goodpost:

Thanks m1482 for the solution. I've tested it on 1 bluray disk now and it worked!

But did you keep the menu and other extras ? I know tsmuxer can create a bluray structure for the movie only. What I would like to have is method that keeps the original bluray structure intact (as much as possible)....

It is like dvdshrink where the movie is not re-encoded and I just remove audio streams and maybe some unwanted extras (to be replaced by stills...). This may work for blurays which are only a few Gb above 25 Gb....

I stripped a 26 GB .m2ts by removing one audiotrack and cutting the ending credits. Using tsMuxer I created a new 00000.m2ts (output .m2ts, not Blu-ray structure), simply dropped the resulting file in the original BDMV/STREAM directory and burned the data on a BD-RE. I did not do anything to .clpi files and the resulting BD-RE works pretty well. Granted, FF, RW and chapter skipping don't work properly - but using tsMuxer to create an entire Blu-ray structure from a single .m2ts file has the same result.

Ok, this is what happens...
When you create a new "m2ts" file with different specifications from the original (for example: audio change from ac3 5.1 > 2.0 or dts > ac3, or encoding type from VC1 > h264 or mpeg2> h264), that info is included in your new "clpi" file. If you change your file specs and doesn't include the new info (cpli) your player would not recognize your new created m2ts file...

All my players played the BD-RE just fine - apart from the FF, RW and chapter skipping issues. Had I created the entire BD structure with tsRemux from the single original m2ts, the resulting disc would have worked exactly the same (i.e. FF, RW and chapter skipping issues), although it wouldn't have contained the original menus.

Your example lists some rather radical changes from the original. In that case I'm sure one needs to update the clpi files as well. All I did was remove one audiotrack and cut the ending credits and it seems to me that in that case one can use the original clpi files.
