Transition
Transitions are used to change the background
video and take keys on and off air. A transition
can include any combination of background
and keyers for an ME. The background and each
keyer can be transitioned independently and at
the same time using the dedicated
KEY CUT
and
KEY AUTO
buttons.
Performing Transitions
What you can include in the transition, and the
type of transition you can perform, depend on
the number of media resources you have, and
if you are performing a background and keyer
transition at the same time.
Keep the following in mind:
Keep the following in mind when performing
transitions:
• The
PGM A
and
PGM B
buttons on the
transition module select which configurable
program output the transition module and
source buses are assigned to.
• The Program B program and preset buses
use the Utility 1 and Utility 2 outputs.
• If the fader is moved during an auto
transition, control of the transition is passed
to the fader. You must complete the
transition with the fader. This allows you to
override any auto transition in progress with
the fader.
• A key only transition can be performed by
pressing the
KEY CUT
or
KEY AUTO
button
for the key you want to transition.
• Double-press the
BKGD
button to select the
background and all on-air keys. The BKGD
Double Press option must be turned on.
• The time duration of a transition will vary,
depending on the video format the switcher
is operating in. Transition rates are set in
frames, not seconds.
• If there are not enough resources available
to perform a transition, a dissolve is
performed instead.
• The Program Out BNC is only fed from the
Program/Preset ME. Any other ME will have
to be re-entered into the Program ME to be
part of the program output.
• If the auto transition includes both a
background and a keyer, the ME Rate is used
for the transition.
Independent Key Transitions
Keys can be transitioned independently using
the dedicated key transition buttons on the
Keyers Module. This allows you to dissolve keys
on/off-air while the fader is off-limit, or an Auto
Transition is in progress from the Transition
Module.
Keep the following in mind:
Keep the following in mind when performing
independent key transitions:
• Only dissolves or cuts can be used for an
independent key transition.
• If the key is part of the next transition, the
key will be dissolved off-air and is removed
from the next transition. This applies even
if the key was not on-air.
• Independent key transitions are performed
at the key rate, and not the ME rate.
• Each keyer has an independent key rate.
• The independent key transitions feature is
not compatible with OverDrive
®
and is
disabled when Editor is enabled.
To Perform a Transition
All Transitions, with the exception of cuts on
the background or key bus, have the same basic
steps. To perform a transition, you must select
what sources you want to transition on what
buses, and how you want the transition to
appear.
1.
On the Transition module, select the
configurable program output (
PGM A
or
PGM B
or both) for the ME that you want to
perform the transition on.
Tip:
The PGM A and PGM B buttons allow you to perform
a split ME transition with an independent A-side and B-side.
Press PGM A or PGM B to have the Transition module and
the background and preset buses assigned to the A-side or
B-side. Press both buttons to have the Transition module
and buses assigned to both sides. Both the A-side and B-side
have independent transition rates but share the keys based
on the configurable program output settings.
2.
Select the elements (
BKGD
or
KEY X
) you
want to include in the next transition. To
select multiple keys and background, press
and hold the first element, and select
additional elements.
3.
Select the video sources you want to take
on-air on the program and key buses.
4.
Select the type of transition (
DISS
,
WIPE
,
DVE
) you want to perform.
