SDI Output Controls
Banks 1/2, if NDI source of 30p from a computer or a phone, and professional
source of 29.97, in order to not create any glitches, you need to decide which
output you want to use — fractional or integer.
Integer vs. Fractional
With this control, you can select integer or fractional. This is relevant when you
have mixed types of inputs, such as 23.98, 29.97, 30, etc.
If there is a mismatch, such as having a frame rate of 25 but the SDI Output
control is set to Fractional, the Status overlay will show a warning and the channel
will stop. Once the mismatch is fixed by aligning the setting and the signal type
to match, you may need to resubscribe to the channel, restart the channel or re-
enable the channel.
• Fractional frame rates are 23.98, 29.97, 59.94
• Integer frame rates are 24, 25, 30, 50, 60
Free Run vs. Ref In
Each of the cards have a reference. Can choose Free run or Ref 1. Relevant for SDI
Output. Not relevant to NDI Output.
Bank 1 and Bank 2 share a Ref In.
Bank 3 and Bank 4 share a second Ref In. Diagram of connectors is shown in the
Cabling Tab.
