View Full Version : Authoring of dual layer Blu-Ray : How do you do ?

Hello.

I've found almost nothing on authoring dual-layer BR on the scenarist doc.

For DVD, you selected when creating the project if you wanted single or dual-layer, and you have to select where you wanted to put the layer break.

I've searched in the doc of scenarist, but found nothing on how to set a dual-layer BR project, not even how to put the layer break.

Does someone has already done dual-layer BR ?
How do you do this, or, if there is information on scenarist 5.1.3 documentation, can someone tell me the chapter/page ?

Thanks in advance.

Well, that explains how to assign the files to the different layers and such, but seems to be missing a critical step... When you to the Disc Layout tool (Tools/Disc Layout or just press Ctrl-L), on that first screen is the option to set the number of layers.

Before you layout your final disc (but wait until you are at that point, if you add any files, including Java stuff, you will have to redo this), go to the Disc Layout tool again, go to 'Physical Layout' and select the Auto Layout button. Pray that it works. :cool: If it's successful, then all the files are sorted onto their appropriate layers and the layer break is picked for you (since it's invisible on playback, it doesn't matter where it is). That's it, you are ready to make the disc image (in fact, even if it's a single layer disc, you should always do this step before making the final disc image).

If it fails, that means it couldn't find a chapter stop to make a good layer break (but it still sorts most all of your files onto the appropriate layers). (For AACS, certain files have to be in certain, specific spots.) You now have to go back to the 'Disc Setting' tab and find a layer break using the PTS Break option and the slider at the bottom. Just kind of trial-and-error until you get layer 0 larger than layer 1, then you have to move a few AACS files. This is covered in the manual at page 446.

If you can get on Sonic's support site, search the Knowledge Base for AACS, there's another doc there explaining a lot of this.

(Again, if the 'Auto Layout' works, you are done... That's what you hope for. :cool: )

Thanks for all these informations.
Something bothering me. When i tried this WE to make my first BR (single layer), scenarist said that layer 0 was at 96%.
Nevertheless, when i've tried to burn the directories on a BD-RE, the data where around 1Go big !! (And around 800Mo on a BD-R, which min BD-RE < BD-R).
So, i'm begin to be a little concern if i try to make dual layer, and the reability of the informations of Scenarist...
I'll see in a few days when re-encoding my videos will be finished.

The percentage indicators in Scenarist (both BD and DVD) are estimates. You can't determine the exact size until it's muxed into an image. I usually try to keep them at 95% or less... Anything higher than that and you run the risk of exceeding the disc capacity.

Also, various BD-Rs and BD-REs have slightly different capacities. I can burn some projects to a Sony BD-R that won't fit on a Panasonic BD-R, etc. (That's an example, I forget the exact brands I had that problem with).

For a BD-25, if your image is under 25,025,314,816 it _should_ fit on a replicated disc... It's usually a good idea to leave at least a few hundred meg padding just in case though. BD50 is double: 50,050,629,632, not like DVD where dual layer is less than double...

When using BD-RE media, if you use IMGBurn to format the disc, and you select prefer format without spare areas, and do a full format, I think you will now have the same space available, or at least pretty close, to a BD-R.
It's been awhile, but I remember this also allowed the BD-RE to burn at 2X instead of 1X.:confused:

I'm using IMGBurn, and i'll try what you've said. Thanks for the advice.
