
DVD Type - A DVD without menus is typically used for showing demo content. Such a DVD can be designed
to play once through to the end and then stop or it can be made to start playing from the beginning every time
the end is reached. A DVD with menus can be made much more useful and interesting, depending on how
much time is put into creating the menus and extra features.

Chapter Selection Options

Arbitrary Number of Chapters
– For this selection, the capture time specified on the previous page will be
evenly divided up to obtain the length and hence the starting position of each chapter. If the capture is
stopped for any reason before the specified capture length, there may be fewer chapters than specified if the
capture was stopped before the last chapter was placed.

Arbitrary Chapter Length
– For this selection, each chapter will be made to be the specified length with the
actual number of chapters not being known until the capture has completed.

Smart Chapter Definition
– This selection applies a proprietary algorithm in conjunction with natural scene
detection to determine the optimum chapter selection. This option can include a combination of natural and
forced chapter breaks. Forced chapter breaks may be used to if there are not as many scene breaks as the
specified desired number of chapters. Forced chapter breaks are simply chapter points occurring at points
that are not the start of a new video scene. These will usually occur within the context of long natural scene
breaks. For example, i
f a camera was set up on a tripod to video tape a lecture or party, etc… there would
be few if any natural scene breaks but it would still be useful to be able to skip through or directly jump to
sections of those long scenes by using DVD chapters. Finally, in the context of the thumbnails printed on the
case wrap, it is a way of giving an overall picture of the video content even if there are few of no natural
scene breaks.

Scene Detection Only
– This option will place chapters at points determined to be new scenes by the
automatic scene detection code. If the video has glitches, sync problems, or just rapid panning, spurious
scene starts may be detected. These problems are usually minimized by the 'Smart Chapter Definition'
selection.

No Chapters
– This option will not create any chapters. There will also be no chapter thumbnails for a DVD
menu or for the case wrap.

Custom Chapters
– This option will allow the user to specify the time codes for the chapters, along with some
text that will be associated with the chapter and optionally a bitmap to use in place of the first frame of the
chapter. The chapter text will be rendered to the DVD menu if the menu theme so specifies. The chapter
