Using the Built In Switcher
Using the Built In Switcher
Blackmagic Web Presenter features a built in 2 input live switcher. However, to take advantage
of this feature you need to install the Teranex Mini Smart Panel. This panel adds an LCD screen
and pushbutton controls that you can use to control the built in switcher. Once the Teranex Mini
Smart Panel is installed, the switcher feature will be enabled.
When both SDI and HDMI video sources are connected, the HDMI input will be resynchronized
so that both inputs can be transitioned without glitches. This is what makes the Web Presenter
able to do live switching.
To operate the built in switcher, simply press the 1 on the front panel to select SDI as the video
source or the button marked 2 to select the HDMI video source. Once selected, the Web
Presenter will do a short half second cross dissolve. You could connect a computer with a slide
show to the HDMI input and a camera to the SDI source and do very professional live
presentation shows for your audience, simply by switching using the 1 and 2 buttons. You can
also confirm the current input, the video preview and audio levels on the LCD screen.
When switching a live broadcast using Blackmagic Web Presenter
with a Teranex Mini Smart Panel attached, press the 1 and 2 buttons
to switch between the SDI and HDMI inputs
Using Camera Tally
Blackmagic Design studio cameras and ATEM switchers include a tally feature where the tally
information is sent from the switcher to the camera via the program return feed from the
switcher to the camera. Your Blackmagic Web Presenter also includes this tally feature so you
can see which camera is “on air” when you are using the switcher feature on the web presenter.
Using tally is quite simple and all you need to do is connect the SDI output of a Blackmagic
Design Studio Camera to your web presenter as an SDI video source and then connect the
program output of the web presenter back to the camera progam SDI input. Now when you
select the program button on the camera you can see the web presenter’s program video on the
camera. But what’s even more exciting is the tally information is now being sent to the camera.
The SDI video input is tally “camera 1” and the HDMI input is tagged as “camera 2”. So what this
means is that in your camera’s settings, you will need to set the camera number. In this case we
are using the SDI input for the camera, then the camera should be set to camera 1. Once this
has been set, and you press the 1 button on the front panel of the web presenter, you should
see the tally illuminate on the camera.
