The Build Files for SD Projects
Once the build for your SD project starts, DVD Studio Pro creates two folders at the location
you specified: an AUDIO_TS folder and a VIDEO_TS folder. Additionally, a third folder,
JACKET_P, is created if you have assigned a jacket picture graphic.
The AUDIO_TS folder is used by systems authoring DVD-Audio titles. To meet the DVD
specification requirements, DVD Studio Pro creates the folder and leaves it empty. The
empty folder is included in the format process.
The JACKET_P folder contains three resolutions of the graphic assigned as the jacket
picture. See About Jacket Pictures for more information.
The VIDEO_TS folder contains all of the DVD-Video files for your project, and is placed in
the video zone. The naming and structure contents of the VIDEO_TS folder are tightly
regulated. All SD DVD titles use the same filenames and structure their contents in the
same way.

Standard SD DVD Video Zone Files
The following groups of files are present in the video zone of all SD DVD-Video titles.
Video Manager Group
The video manager files contain much of the navigation information for the title.
• VIDEO_TS.IFO: Contains the major information for the disc, such as its capacity and
video zone structure.
• VIDEO_TS.BUP: This is a backup of the .IFO file that can be used by the DVD player if
the .IFO file cannot be read.
• VIDEO_TS.VOB: This is the video objects file for the video manager.
