The advantage of using the built-in method is, that it is possible to switch between a live signal and the playout of a movie without the need of a video router. In addition it is possible to add graphics to the live signal without the need of a second video device.

Like described above, there are two methods to achieve this and here is how the NON DSK based setup has to be done.

Make sure the right Firmware is loaded (AJA only)

Using the AJA Control Panel, the device must be flashed to the 4K mode with 2 inputs and 2 outputs before it can be used.

  • Select the Firmware tab and ensure that the installed firmware is (4K Mode).
  • If not, select (4K Mode) from the desired menu and click the Install... button. Follow the instructions to flash the correct firmware.


Activating the 4K mode of an AJA device, the ability to do hardware based Up, Down and Cross conversion as well as the ability to activated the DS Keyer or to play out Fill&Key will be disabled.



Select the right switch to live method for your channel

Open the Advanced Output Format settings of just:connect and select one of the available Without DSK-based settings.

  • Without DSK, default black: Black will be played out in case nothing is playing in the timeline of the UI.
  • Without DSK, default pass-through: The connected signal will be played out in case nothing is playing in the timeline of the UI.

Connect a signal and select the input in the Advanced Output Format settings.

  • Connect the live signal to SDI 2 (AJA) or SDI 1 (BMD).
  • Please enter the input where the live input is connected to.


Using an AJA, the final output will be shown on SDI 3, using an BMD, all outputs will be active.


Passing through ClosedCaption data

Make sure to activate the VANC option under the Format tab of the AJA control panel to pass through any CC data which comes with the input signal. Passing through of CC data is only supported using devices from AJA (Kona 4) while using a "Without DSK" or "Disabled" Live SDI input configuration in the channel settings of just:connect.
