Incremental Builds like in Apple DVD Studio Pro

Incremental Builds


While creating your project, you may find it useful to perform builds several times before

you are actually finished with it. These incremental builds can be useful to verify that

certain aspects of the project are functioning properly, such as a set of scripts or a menu’s

button navigation.

To help with this process, DVD Studio Pro includes the ability to reuse unchanged elements

from a previous build. This can greatly speed up the build process when you perform

incremental builds.

Once you select a folder to build into, DVD Studio Pro checks to see whether a folder of

the same type it needs to create (VIDEO_TS or HVDVD_TS) is already present. If the folder

already contains a folder of the same type, with a .layout file that has the same name as

the project, a dialog appears for you to specify what should happen.


Cancel: Closes this dialog and the build process without saving anything.


Delete: Deletes the current contents of the VIDEO_TS or HVDVD_TS folder and begins

saving the new build information.


Reuse: Attempts to reuse as much of the current VIDEO_TS or HVDVD_TS folder contents

as possible.


If you decide to reuse the VIDEO_TS or HVDVD_TS folder, DVD Studio Pro looks at its

contents and, for each VTS block, checks to see if anything has changed from the last

build. If the VTS block has not changed, the message “VOB up to date. Muxing skipped”

appears in the Log tab and the build moves on to the next VTS block.
