Setting the Break Point with Large DVD-ROM Contents
Authoring a project that contains a small amount of DVD-Video data with a large amount
of DVD-ROM data requires special handling for placing the break point. For example, you
might author a project for a dual-layer red laser disc that contains 2 GB of DVD-Video
data and 6 GB of DVD-ROM data. In this case, you will not be able to set a break point at
a track’s marker because the DVD-ROM data will not fit on a single layer.
In these cases, setting the break point to Automatic places the break point in the DVD-ROM
data.
Setting the Dual-Layer Break Point
There are several methods you can use to set a dual-layer break point:
• The automatic method: By default, once you configure the disc as dual-layer, Automatic
is selected as the break point in the Disc/Volume tab in the Disc Inspector. With this
setting, DVD Studio Pro chooses the last marker that fits in the first layer. In cases where
there is a large amount of ROM data, the automatic method can also place the break
point in the ROM data. See
Setting the Break Point with Large DVD-ROM Contents for
more information.
If you are using the Build/Format command, the automatic method has the greatest
chance of success, because it will be able to choose the break point marker once the
build process is finished without having to pause for you to choose the marker to use.
It is possible that your project does not have a suitable marker for use as the dual-layer
break point. In that case, the format is canceled and you must add a suitable marker
to a track in your project. (Another option might be to rearrange the order of the tracks
in the VTS Editor. See
Moving Elements from One VTS to Another for more information.)
See Manually Determining the Break Point Position .
• Assign a break point marker in the Track Editor: This method allows you to choose the
marker to use as the break point while working with your tracks. The disadvantage of
this method is that, until you build your project, it can be difficult to choose a suitable
marker as the break point. This is especially true if your project has a lot of transitions
or you are using assets that have not yet been MPEG-2 encoded.
If you choose an inappropriate marker, the format process will automatically cancel,
with a dialog advising you of the problem it encountered.
• Choose the break point marker when you start the format process: After you have built
your project, the Dual-Layer Break Point pop-up menu in the Disc/Volume tab in the
format dialog shows all suitable markers that you can choose from, with those that are
inappropriate dimmed. This option has the advantage of letting you choose the marker
to use from a list of known suitable markers. The disadvantage is that you have to build
your project first.
