Page 654: Replication facility, Pan-scan
pan-scan A method for displaying 16:9 video on a 4:3 monitor. Content is cropped at
each end so that the 4:3 monitor is filled. An MPEG-2 video clip with pan and scan can
include vectors that dynamically change the part of the picture that is cropped. See also
parallel track path (PTP) Used when creating dual-layer discs to control where the second
layer starts. With PTP, the second layer starts at the inside edge of the disc, the same as
the first layer. See also
.
patches Specialized shapes that provide features not normally available with traditional
shapes, such as shading and colorization. You cannot create your own patches. See also

P-frame Predicted frame. In an MPEG video stream, P-frames are encoded based on the
closest preceding I-frame or P-frame. They can be referenced by B-frames occurring before
or after them. With respect to file size, they are not as efficient as B-frames, but handle
abrupt scene changes better. See also

pixel aspect ratio The distance between a pixel, the one next to it, and the one below
it defines its aspect ratio. A square pixel aspect ratio, as used on computer systems and
HD video monitors, has the same pixel distance in both directions. SD video monitors do
not have the same distance in both directions, and have rectangular pixels. NTSC and
PAL video each have different pixel aspect ratios. This difference must be accounted for
when creating graphics on a computer for use in an SD project.
project When you author a DVD title with DVD Studio Pro, you create and work in a
project.
red laser Refers to the color of the laser used to play the discs used by SD projects. See

region codes DVDs can be set to play only in certain parts of the world by selecting the
supported regions when you author your title. The DVD specification divides the world
into six regions plus an additional region for use by airlines and cruise ships.
replication facility You can use a replication facility when you need to reproduce a
significant number of copies of your DVD (generally more than 100). You must use a
replication facility if you require dual-layer discs, or if you intend to include high-end
features such as copy protection or region codes. Replication facilities use a glass mastering
process to create DVDs that are compatible with all DVD players, as opposed to the DVD-R
process used by duplication facilities. See also
scripts Simple programs you create to access specialized information from the DVD
player, such as its region code, and to perform advanced functions, such as randomly
playing all tracks. You can connect most elements of a project to scripts. See also
