Scrollable text in special extras menus for Blu Ray

[Tsunoni]

I'm very new to making BDs and would like to know which software would be able to do this.
What would be a good software that can make a section in a Blu Ray menu with a gallery of selectable images which bring up each image along with a few paragraphs of scrollable text about the image?
Like a 'Special Features' or 'Extras' section with a gallery and description per image.

You want to control the text scrolling by RC arrow keys ?

1) Hire a Java developer to design that gadget from scratch and get him to build that Java Package
(.json and a few folders with graphic assets)
and
2a) buy Scenarist BD/UHD, or DVDLogic KITe,
or
2b) become a licensee of Panasonic Authoring Systems, or Sony Blu-print
or
2c) hold an old license of DoStudio, or Indigo
and
3) inject Java package, mux, done.

A bit joking, it should work without the mentioned authoring SW, like copying the Java package into the JAR folder,
and edit some .bdjos into the BDJO folder. These .bdjos may be concluded.
I guess you only might need BD Edit then to edit the index.bdmv to reflect it is a BD-J.
HDMV/BD-J Mixed Mode ? Uh-oh. Can not tell.

As recent requests revealed, both mentioned softwares 2a), and DoStudio can not design any Java package, only ingest.

And trying to steal a close-by design from an existing BD-J to modify it might not work at all.
Looking at the more than 100 java classes from a rather simple BD-J blu-ray it became obvious that each and every class is signed with a SHA digest.
Edit it and it becomes invalid. Only the owner of the project files may be able to modify his project.

"...nice, Mr. Gosling. And I had wondered why it had to become exactly Java that was forced down some throat here and there..."

Constantly scrolling text can be achieved in HDMV.

Are you saying that it is only possible to make scrollable text through making a new Java code for it? Can any of those licensed softwares do it without writing an additional/new Java code? I want to avoid Java if possible because I think there should at least be a software to make a menu with the picture and text as the background and an arrow to go to another menu with the same background but it has the rest of the text (as a work around sort of job)

I think there should at least be a software to make a menu with the picture and text as the background and an arrow to go to another menu with the same background but it has the rest of the text (as a work around sort of job.)I can't speak for other software, but it's certainly possible using BDedit. I can provide you an example if you like. I'll work something up this evening and chime back in here providing a download link. You can then look it over in BDedit and view the end result in a software based Blu-ray player that supports BDMV folder playback.

That'd be great, I would really appreciate that

I think I use DVDStyler to make everything then use DVDtoBD Express to turn it into a BD. One thing I am not sure about is if I can just encode a video to x264 and save it as .vob and replace the videos that DVDStyler made so that its a better quality video. That should work ok right? Not sure if the codec would be compatible or if I need to change another thing

I was going to work up an example for you, but never got around to it. That being said, navigating multiple pages of text from the same menu page can easily be accomplished. It's just a matter of enabling/disabling buttons, the objects (images) of which contain the text in question. The easiest way to implement this is to place each button (displaying the given text) within the same Button Overlap Group (BOG). Only one button within a BOG can be enabled at any given time. When enabling a button within a BOG the other buttons within the BOG are disabled automatically. I follow this practice throughout the HDMV based Blu-ray menus I create. I provide a number of examples on "Page 2" of the thread found here (https://forum.doom9.org/showthread.php?t=182746). My latest post (https://forum.doom9.org/showthread.php?p=1969825#post1969825) in that thread would be a good place to start. ;)
