Figure 5-21 shows the A/B mixer’s ‘Profiles’ sub-menu:
Figure 5-21. A/B Mixer (Profiles Sub-Menu Shown)
In this menu, you can adjust the down time, mid time, and up time (or rise time) of individual tran-
sition types.
Select the transition type that you want to modify. In Figure 5-21, the U-fade transition is selected
and highlighted in green.
At the bottom of the menu, are 3 controls with which you can adjust the transition parameters
(down time, mid time, and up time). Touch a knob proxy next to the control and use the slider that
appears to change the setting. You can also touch the keypad button of the control to access a key-
pad in which to change the parameter numerically.
S You cannot change the parameters of the ‘cut’ transition type and you cannot change the mid
time of the X-fade.
S A non-zero mid time for a transition type results in a dwell period in the middle of the transition
(as for a U-fade).
The values for down time, mid time, and up time range from 0 to 100. They appear here as percent-
ages, but in actuality they are integer values representing a fraction of the transition period accord-
ing to the following formulas:
D = down time / sum where sum = down time + mid time + up time
M = mid time / sum
U = up time / sum
and
D
′
(frames) = F × D where F is the total number of frames in the transition
M
′
(frames) = F × M
U
′
(frames) = F × U
all rounded to the nearest integer.
