Adjust Profiles
Figure 5-21 shows the A/B mixer’s ‘Profiles’ sub-menu:
Fig. 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
transition 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 keypad 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 transi-
tion (as for a U-fade).
The values for down time, mid time, and up time range from 0 to 100. They appear here as
percentages, but in actuality they are integer values representing a fraction of the transition
period according 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.
