About Replace GPIs
When you use the Replace function, you have the option to use external devices
manually. You can also trigger the external devices by specifying a GPI OUT to occur on
the IN and/or OUT of the Replace function. In this case, the server will send a first GPI
OUT signal to the external device at the IN point and a second GPI OUT signal at the
OUT point or when the user stops the Replace process manually.
For each GPI OUT, you need to define the GPI number and the type of GPI that will be
sent.
About GPI Offsets
You can also specify an offset for each GPI. The offset shifts the position of the GPI
compared to the mark IN or mark OUT point. It allows, for example, an audio mixer to
make smooth configuration transitions or a graphic keyer to make dissolves for graphics.
You can define:
• a positive offset for the mark IN to send the GPI after the replace process has started.
• a negative offset for the mark OUT to send the GPI before the replace process has
stopped. The offset is not taken into account when the Replace process is stopped
manually.
How to Define a GPI OUT for Mark IN and Mark OUT
points
1. Right-click anywhere in the timeline and select Replace Settings.
The Replace Settings window opens.
2. To define a GPI on the mark IN point, do the following in the Boundary Mark GPIs
group box:
◦ Select the number of the GPI OUT to use on the mark IN in the Mark IN GPI OUT
field.
◦ Select the type of GPI OUT pulse in the Output Mode drop-down box.
◦ For Pulse GPIs, specify the pulse duration in the related field.
◦ If requested, type the offset to apply to the GPI in the Post Mark IN Offset spin
box.
3. To define a GPI on the mark OUT point, perform the operations described in step 2 for
the Mark OUT GPI fields.
4. Click Apply to save the Replace settings.
When the mark IN and mark OUT for the replace function are placed on the timeline, the
Replace GPIs are displayed on the Timecode bar as a green marker for the mark IN GPI
and a red marker for the mark OUT GPI. The GPI number is mentioned on the marker and
the marker position takes the offset into account:
