timecode A method of associating each frame of video in a clip with a unique, sequential
unit of time. The format is hours: minutes: seconds: frames. See also

drop frame timecode

,

non-drop frame timecode

.

track The element of a DVD Studio Pro project that contains the video, audio, and subtitle
streams that provide the primary content of the DVD. Each project can have a combination
of up to 99 tracks, stories, and slideshows.

transitions A short video clip that plays in place of the normal direct jump from one
button or still image to the next element. There are a variety of transition types supplied
with DVD Studio Pro that you can use. Transitions can be configured between a menu
button and its target, between slides in a slideshow, and between still image clips in a
track.

variable bit rate (VBR) encoding A video MPEG encoding method that varies the bit rate
based on the video content. Scenes with little motion use low bit rates to reduce the disc
space needed, while scenes with a lot of motion use higher bit rates for greater quality.
One-pass VBR encoding is faster than two-pass VBR encoding, but its quality is not quite
as good and the final file size may be slightly different than you predicted. Two-pass VBR
encoding makes a first pass through the video to determine its motion content, and then
uses a second pass to perform the encode, with the advantage of better quality and
providing a predictable file size.

VIDEO_TS folder One of two folders required on DVD-Video discs (the AUDIO_TS folder
is the other). DVD Studio Pro creates the VIDEO_TS folder when you build your SD project.
It contains all of the video, audio, subtitle, menu, and navigation files that make up your
DVD-Video title.

video title set (VTS) The contents of a DVD are contained in one or more VTS blocks.
DVD Studio Pro creates a VTS block for each track and slideshow in your project, with a
maximum of 99 total. In addition to a track or slideshow, each VTS can also contain menus
and scripts. You can use the VTS Editor to view and manage the VTS structure of your
DVD projects.

video zone The area of the DVD that contains the VIDEO_TS or HVDVD_TS folders.
