Effect Dissolve
Effect dissolve produces a smooth transition from the current state of the
work buffer to the state defined in a recalled register. Effect dissolve first
takes to the source and other button settings specified as a starting point in
the effect register. The parameter settings in the work buffer then smoothly
change so they match the settings of the recalled effect register. Effect dis-
solve can also simultaneously perform a transition to the specified ending
sources at a specified duration.
An interpolator is used to smoothly change the parameters settings
involved in an effect dissolve. Before performing an effect dissolve, source
and other button settings in the work buffer should be compatible with
those in the effect dissolve register. This prevents an abrupt change when
the new button settings are taken, and so permits smooth transitions
between sources. One way this can be accomplished is by using two dif-
ferent, but complimentary, effect registers.
For example, if register 2 contains compatible button settings, it can be
recalled into the work buffer. If an effect dissolve is then performed to reg-
ister 3, the transition occurs and the parameters from register 2 in the work
buffer are interpolated to those of register 3. Register 3 becomes the new
current effect (
Figure 36 ).
Figure 36. Effect Dissolve
Note that the effect dissolve does not occur directly between two registers,
and the transition aspect is handled separately from the interpolated
parameter values. If work buffer parameter settings are changed before an
effect dissolve, the current modified work buffer values (but not the source
and button settings) will be smoothly interpolated to the new register
values.
