Fader Bar
The fader bar is used as an alternative to the AUTO button and allows the operator to manually
control the transition with a mouse. The AUTO button illuminates red for the duration of the
transition and the 'rate' display updates to indicate the number of frames remaining as the
transition progresses.
Transition Style
The transition style buttons allow the operator to select one of four types of transitions; mix,
dip, wipe and DVE. The selected transition style is indicated by a yellow illuminated button.
Selection of these buttons will be reflected by the corresponding tab in the 'transitions'
processing palette. For example, when you have the transitions processing palette open and
click on a transition style button, the transitions palette will match your selection so you can
quickly adjust the settings.
PREV TRANS
The PREV TRANS button enables the preview transition mode, allowing the operator to verify
a mix, dip, wipe or DVE transition by performing it on the preview output using the fader bar.
When the PREV TRANS is selected you will see the preview output match the program output,
and then it's simple to practice your selected transition with the fader bar to confirm you are
going to get what you want. This is a very helpful feature to avoid mistakes on air!
Next Transition
The BKGD and KEY 1 buttons are used to select the elements which will transition on air or off
air with the next transition. More upstream keyers are available on 4K model ATEM switchers
and that is why other upstream keyers appear greyed out. The key can be faded on and off
when the main transition occurs, or you can select just the key to transition individually, so the
main transition control can be used to fade the key on and off.
When selecting the elements of the next transition, the switcher operator should look at the
preview video output because it provides an accurate representation of what the program
output will look like after the transition is completed. When only the BKGD button is selected,
a transition from the current source on the program bus to the source selected on the preview
bus will occur without the keyer. You can also select only keyer to transition, leaving the current
background live throughout the transition.
ON AIR
The ON AIR indicator button indicates when the key is currently on air and can also be used to
immediately cut the key on or off air.
Downstream Keyer
TIE
The TIE button will enable the downstream keyer, or DSK, on the preview output, along with the
next transition effects and tie it to the main transition control so that the DSK can be taken to air
with the next transition.
The DSK will transition at the rate specified in the 'rate' display of the transition control block.
If the DSK is tied, the signal routing to the clean feed 1 is unaffected.
ON AIR
The ON AIR button is used to cut the DSK on or off air and indicates whether the DSK is
currently on or off air. The button is illuminated if the DSK is currently on air.
