Some cards from Blackmagic-Design require you to set the connector mapping to support some features.
Here is what the default connector mapping of the cards allow you to do:
- with a Decklink Duo 2, you will have maximum 2 in and 2 out
- with a Decklink Quad 2, you will have maximum 4 in and 4 out
- with a Decklink 8K Pro, (drivers 11.1 and later) you will have maximum 1 in or 1 out
So if you want to use 4 individual inputs on the Duo 8 or 8K Pro, or 8 individual inputs on the Quad 2, you will have to change their connector mapping.
What is the "Connector Mapping" for ?
The main reason for this option is that Blackmagic-Design wanted to do 2 things:
- have a card with configurable in/out
- have the possibility to do internal and external key (which requires to "group" connectors")
- have the possibility to have a "passthrough" when using an ingest application such as MovieRecorder (so when you start MovieRecorder, the incoming signal is sent to the other connector for monitoring purposes.
- maintain compatibility with the previous versions of Decklink Duo and Quad cards (this is why the card is configured by default with the connectors "grouped")
Where do I change the "Connector Mapping"?
To change the connector mapping, start the application “Blackmagic Desktop Video Utility”, then:
- Use the left and right arrows to select the "Device" you want to configure.
- For a Decklink Duo 2, you will have 4 "devices" named by default "Decklink Duo (1) -> Decklink Duo (4)
- For a Decklink Quad 2, you will have 8 "devices" named by default "Decklink Quad (1) -> Decklink Quad (8)
- For a Decklink 8K Pro, you will have 4 "devices" named by default "Decklink 8K Pro (1) -> Decklink 8K Pro (4)
- Once you have selected the device you want to configure, click on the settings icon:
- Then click on the "Connectors" section:
- This will open the setting page for the “Connector Mapping”. Depending on the device that you use, the connector mapping will be different.
Connector Mapping for the Duo 2 and Quad 2
- By default, for the first device, it should be set to Connector: SDI 1 & SDI 2. This means that the connector number 1 and connector number 2 are "grouped".
- To be able to use the 8 individual inputs of the Quad 2, you should change the Connector mapping to "SDI 1" for the Decklink Quad (1), and do the same thing for the devices 2, 3 and 4:
Connector Mapping for the 8K Pro
- (a quick reminder that this will work only with drivers 11.1 and later)
- By default the selected connector mapping should be "SDI 1&2 In, SDI 3 & 4 Out".
- To be able to use the 4 individual 12G 4K inputs of the 8K Pro, you should select Connector Mapping "SDI 1 In or Out". No need to change anything else on the other devices, the changes will be automatic.
What is the recommended configuration for Softron ?
In most situations with our software, you will want to change the connector mapping so they are NOT grouped. So for example,
- for the Decklink Duo 2 or Quad 2, for device "Decklink Quad (1), set the connector mapping to "SDI 1", etc... This will allow you to really configure the inputs and outputs the way you want.
- for the Decklink 8K Pro, select "SDI 1 In or Out"
You will only want to "group" the connectors in the following cases:
- with out playout applications, if you want to playout using the keying feature of the card. See below for more explanations on this.
- with our ingest applications, if you want to have a passthrough of the incoming video to the output connector
- with the 8K Pro, if you want to ingest/playout in 8K
Decklink Duo 2 and Quad 2 capabilities
Depending on the connector mapping selected, the capabilities of the card will be different. Let's take the example of the device "Decklink Quad (1)" of a Quad card.
Connector Mapping = SDI 1 & 2
Maximum number of inputs and outputs
When using connector mapping 1 & 2, you won't be able to use the device "Decklink Quad (5)", as that device would otherwise use the connector SDI 2.
Indeed, if you configure the devices 1 to 4 to use "grouped" connectors, then the connector mapping will look something like this:
As you can see you can thus have maximum 4 inputs and 4 outputs. Not 8 simultaneous inputs.
Keying with our playout applications
With our playout applications, if you:
- enable internal keying , the input will be made on the connector SDI 1 and the output on the connector SDI 2
- enable external keying, the Fill will be made on connector SDI 1 and the Key will be made on connector SDI 2:
Connector Mapping = SDI 1
In that configuration, you won't be able to do keying with our playout applications, but you will be able to use connector SDI 1 and SDI 2 independently. And thus, if you configure the devices 1 to 4 to use "independent" connectors, then the connector mapping will look something like this:
Note that the order of the connectors can be quite confusing...
Also, you won't be able to do keying with our playout applications.
Decklink 8K Pro capabilities
With the Decklink 8K Pro, Here is what each can do:
|Connector Mapping (for device 1)||SDI 1 In or Out||SDI 1 In, SDI 2 Out||SDI 1& 2 In, SDI 3 & 4 Out||SDI 1 to 4 In or Out|
|Profile||4 sub-devices||2 sub-devices||1 sub-device full-duplex||1 sub-device half-duplex|
|Number of devices seen in Softron||4||2||1||1|
|Duplex modes||Each device is in or out. If you use device 1 in MovieRecorder you can not use it in OnTheAir Video.||Each device is in AND out. If you use input 1 in MovieRecorder, you can still use output 1 in OnTheAir Video.||If you use the device in MovieRecorder, you can still use it in OnTheAir Video.||You can use the device in OnTheAir Video or MovieRecorder. Not both at the same time.|
|Loop through||NO||YES (when using input 1, the signal will be looped through output 1)||YES (when using device 1, the signal will be looped through connector 3)||NO|
