Using the Calculated Bit Rate
The bit rates you calculate can be used as the bit rate entry of your encoder, regardless
of the encoding method you intend to use (one pass, one-pass variable bit rate [VBR], or
two-pass VBR). See
MPEG Encoding Methods
for more information.

Appendix C
Calculating Disc Space Requirements
Most of the parameters of the standard transitions supplied with DVD Studio Pro are
self-explanatory. However, some parameters are not as obvious. This appendix explains
the parameters for each of the transitions. For details on using transitions with menus,
see
Using the Menu Transition Feature
. For details on using transitions with tracks, see
Adding Transitions to Still Clips
. For details on using transitions with slideshows, see
Using
Slideshow Transitions
.

Transition Duration
All transitions have a duration setting. The duration can be set from a minimum defined
for each transition (usually one second) to a maximum based on the source length or
10 seconds maximum, whichever is smaller. For example, a slide with a duration of 5:00
can have a maximum transition duration of 4:15 because the minimum duration for a
slide is 15 frames. (This is in an NTSC project—in a PAL project, the maximum transition
duration would be 4:13 because the minimum duration for a slide is 12 frames.)
Video Transition
Menus and buttons have an additional transition to choose called Video Transition. With
Video Transition, you choose a video asset to play as the transition when a button is
pressed.
