Categories and Channels setup.
7.2.2 Profile Setups
A typical example for when it makes sense to use different profiles would be a
backup configuration where a switch from a main to a backup renderer is needed.
For example if two output renderers are named A and B, where A is program and
B is preview, a profile named “Main” will then have channel A as program and
channel B as preview.
A profile named “Backup” could, if the renderer acting as program (A) in the
“Main” profile fails, have channel B as program.
Note that a channel can be designated as a Program or Preview channel by
selecting the check box in the appropriate columns (Program or Preview);
however, the program and preview channels are reciprocally exclusive - only one
channel can be set to program, and only one channel can be set to preview. If for
example A is set to program and B is set to preview, and then C is set to program,
A will no longer be set as program.
GPI
Another example of typical use of profiles is when playout is controlled through a
General Purpose Input (GPI), for instance through hardware such as a vision
mixer.
When GPI is enabled, the external cursor (the GPI system’s cursor) will be
displayed/shown in any client that is using the same profile as the external
system. A typical setup would be that one Viz Trio client is in the same profile as
the GPI system, and functions as a “prepare station” for the producer sitting at the
vision mixer desk. Data elements are then made ready and displayed on a preview
visible to the producer, and then the elements are triggered from the vision
mixer. This configuration needs a separate “GPI” profile that is not used by other
control application clients. Other clients can be in other profiles and produce
content to the same output channels. However, they need to be on other
transition layers or on another Viz layer so that they will not interfere with the
graphics controlled by the external system.
VDCP
If you are browsing the Cliplist for clips on other video devices (that support the
Multiport Video Control Protocol (MVCP)) you may add these clips for manual
playout in any playlist regardless of the profile configuration.
