Encore BluRay menu size limit??

guess we can't quote each other anymore? it'd been forever since i've needed to walk down the adobe forums. 🙂 anywho,

"All I know its max 18 buttons for a widescreen menu."
-no problem at all. i think the the most link heavy menu page i will have is like 9 buttons? i'm just more concerns with video backgrounds and such.

"for Blu-ray authoring, it's not a matter of how motion heavy or effects heavy your menus are as the motion menus are based on one video stream. So it's a matter of how long your motion menus are instead."
-yeah i understand that, but if you have say 3 cumulative minutes of BG video for a menu then its probably nothing... if you have 1 hour of cumulative video, the bitrate of the video directly would need to be considered, vs how many menus, and yadda yadda. i probably won't overbudget the 1gb, but i just want to know for sure before going down that path. i think i had also been thinking for some reason that transitions would be budgeted into that, but i just remembered that transitions are seperate from menus, so it probably won't be that bad.

"On the DVD side, the 1GB data structure limit is not direclty related to menus"

-that actually makes sense based on the vob restriction. so was that how it was all long? because i had always understood that there was a hard restriction of 1gb menu assets, as if encore sandboxed all of your menus into one zone, and if all of that content was more than 1gb cumulatively, the disc would fail. but perhaps i understood that wrong then.

Yes, for DVD there is a 1GB limit for menus (including video/audio assets used in menus).

BD does not have that limit, but it is complicated. I think Encore uses the IG (inteactive graphic) BD method, rather than the more powerful BD-J. From Daniel Ludwig on Cow way back:

"it´s got a 16MB limit for all IG (interactive graphics) within one title (menues are a titles as well), as the IG-stream will be loaded completly into the players RAM-buffer before starting the title."

No, I don't remember what that means. I'd do what you want, and then see if it works!

just want a ballpark before i start this next menu, as it will be HEAVY on motion effects. thanks.

If i remeber correctly i have had approx three minutes in total video length that was encoded at 30 Mpbs and it worked. (Encore CS6)

For all your questions about Blu-ray discs, this book is the best resrource:

You're talking just the menus, right?

As far as your bit-budget is concerned (that is, how much space the data - the menus, video, stills audio and/or anything else you're including on the disc - requires) for Blu-ray authoring, it's not a matter of how motion heavy or effects heavy your menus are as the motion menus are based on one video stream.   So it's a matter of how long your motion menus are instead.

On the DVD side, the 1GB data structure limit is not direclty related to menus.  The video objects have to be broken down into 1GB chunks (the VOB), but this can be menu space and title space.  

For both BD and DVD, the menu only takes up as much space as the encoded video stream needed for the menus.  For example, if your DVD menu source is encoded at 3.7mbps, then you're looking at about 111mb for a thrity second menu regardless of what happens visually. 

All I know its max 18 buttons for a widescreen menu.
