Timed crossfades
Sometimes you may prefer to change scenes using timed crossfades.
Because they are not controlled by physical movement of the cross
faders, timed crossfades are generally smoother than manual fades,
especially when the fade takes place over a relatively long time. The
primary difference between manual and timed cross fades is the role
of the cross faders.
In manual crossfades, the speed at which you move the cross faders
determines the fade rate. In a timed crossfade, you establish the fade
rate by setting the position of the Time sliders. For example, set the
scene A Time slider at
1m
(one minute), then move the scene A
cross fader from
10
(100 percent) to
0
(zero percent). Scene A fades
out in one minute.
In a timed crossfade, the Time slider controls how long the fade takes
and the cross faders control the extent of the fade. In the example
above, if you move the scene A cross fader to
5
, scene A output
fades to only 50 percent over a period of 30 seconds. The fade
rate
stays the same because the Time slider setting is not changed, but
the fade does not finish if the cross fader is not set to
10
.
Each cross fader has its own Time slider, which gives you
independent control of the rate at which the two scenes fade. For
example, scene A might come up in 30 seconds, while scene B
might take two minutes to fade out. The Time sliders are marked from
0
to
5m
, indicating fade durations of from zero to five minutes. When
you set Time sliders at
0
, you must manually fade the scenes in and
out with the cross faders.
Each fader has a row of LEDs next to it. As a fade runs, the LEDs light
in sequence, tracking the progress of the fade. When you run a
manual fade the LEDs light as you move the fader. When running a
timed cross fade, the LEDs light, and the fade progresses according to
the fade rate determined by the position of the Rate slider.
