3.1.2 Selecting Essences for Play-out
With the Output select settings of the playout mode you have to se-
lect the essences (type of material) that you want to play out. You can
choose whether you want to play out audio, video/alpha or timecode,
as well as all their combinations. By clicking on the triangle button to
the left of the item Output select, the necessary settings can be ex-
panded (or collapsed):
Figure 3-6: The output select items
When the settings items are collapsed, the currently selected essences
will be shown in abbreviated form to the right of the Output select
configurations: T for timecode, V for video and A<x> for the selected
audio channels.
As soon as video and/or audio content is available for a play-out (see
section “Selecting Content for Play-out” on page 3-2), the matching
essences in the user interface will be activated automatically.
With the Output select configurations choose the essences according
to your needs. By activating or deactivating one of the provided but-
tons you can determine the essence that you want to play out. For ex-
ample, if you want to play out video, the button VIDEO must be
activated.
With the button ALPHA ONLY you can choose whether you want to
play out the alpha channel (key) of the video material instead of video.
Then the video overlay and the video outputs will show you the alpha
channel mask of the video clip. The parts of the images displayed in
white are selected, black areas are not selected (i.e. keyed out).
The audio channel buttons above the audio peakmeter represent the
16 audio channels that are provided by the VENICE server. If, for ex-
ample, channels 1 and 2 are selected (as in the figure above), audio
content will be played out at these channels of the VENICE server.
With the button TIMECODE you can determine that timecode infor-
mation should be sent to the connected external device (LTC only). It
will be especially useful when inserting data on tapes of a tape machine
It is not possible to give out timecode alone. At least one of the
other essences has to be selected as well.
Further information about audio and the way it is handled can
be found in section “About Audio” on page 2-18.
