Parameters
For this processing component, you must set the following parameters:
 Maximum format : maximum format that this input can receive.
This information is essential for the load-balancer as it will use it to
allocate resources (CPU, memory, license). Setting an HD format
when the source is SD results in Electra VS system underuse.

If you choose custom , set the Maximum picture size and
Maximum frame rate fields.
 Track ID : you may enter the value directly in the field or use a
predefined value:
 First one : the first track that matches the criteria.
 All : all the tracks that match the criteria.
 Codec : H.264 , MPEG-2 , Apple ProRes , Any . If set to Any , the codec is
automatically detected.
 Clock management : if set to Convert to device internal clock
(default value), then the input clock is converted to the device clock. If
set to
Keep input clock , then the input clock is kept. When you want to
multiplex components from different input programs (to create a
mosaic for instance), the clocks shall be converted to the device clock.
