Apple DVD Studio Pro 4 - Manual (Page 574)

• HV000I01.BUP: This is a backup of the .IFO file that can be used by the DVD player if
the .IFO file cannot be read.
• HV000M02.EVO: This is the enhanced video objects file for the video manager.
Note: The file HV000M01.EVO is not used by DVD Studio Pro.
Track Content Group
A set of at least four files is created for each track and slideshow in the project. “HV001I,”
“HV001M,” and “HV001T” in the following filename examples refer to the first VTS block.
Files for the second VTS block would start with “HV002I,” “HV002M,” and “HV002T.” You
can have up to 99 tracks, stories, and slideshows in a project.
Note: While stories do not get placed in their own VTS block, they still count against the
99 VTS limit.
Enhanced video object (EVO) files contain the actual video, audio, and subtitle content
for the menus and tracks. Within each track content group there are at least two EVO
files—one that is dedicated to menu content and another (up to 99 more) with the track’s
contents.
• HV001I01.IFO: Contains the major information for the first track, such as the number
and types of streams and menus.
• HV001I01.BUP: This is the backup for the .IFO file.
• HV001M01.EVO: Contains the video and audio content for the menus. The properties
of the audio and video used in the menus within an EVO must be the same. If your
project has menus using different properties, they are placed in other VTS blocks
(HV002M01.EVO, for example). See
VTS Editor for more information on menus and VTS
blocks.
• HV001T01.EVO: Contains the video and audio content for the track. If the content is
greater than 1 GB, a second file is created for that additional content. Up to 99 additional
files can be created if required to hold the track’s contents. The last two digits of the
filename increment as additional files are created. For example, the first 1 GB would be
in HV001T01.EVO, the second 1 GB would be in HV001T02.EVO, and so on.
Non-Standard HD DVD Video Zone Files
As part of the build process, DVD Studio Pro creates two additional files in the HVDVD_TS
folder. The format process does not include these files in its final output.
• A .layout file: This file uses the disc name and a “.layout” extension. The file contains
project information used by the format process, including the marker information used
when creating dual-layer discs.
• A VOB_DATA.LAY file: This file is used for incremental builds when you choose to reuse
files in the HVDVD_TS folder left from a previous build for a new build.
