change with future firmware updates. I did figure out how to push the Aux button and then
use a control knob to select the Aux output,
but this workflow involved too many steps and
took too long during a live-switched webcast. I
wanted a better solution to be able to punch in
my desired Aux input.
I contacted my Blackmagic rep for support
and she told me that I could push both the
Shift keys to lock the preview and program
rows to Aux mode and then could use the input buttons to select the desired Aux output
(see Figure 4 on the previous page). Except
there was one problem: Blackmagic currently
provides no documentation as to which button
controls what. After a bit of testing, I determined that I needed to punch 4 to select the
program output and 7 to switch to the input
that corresponded with the slide input. Then,
to return the switcher to the default switching mode with preview and program controls,
I needed to push the two Shift buttons at the
same time again.
Ultimately, I did not like losing the ability to
switch my cameras quickly on the preview and
program bus while in Aux mode, so I resorted
to using the software control panel to switch
the Aux and the hardware to switch the cameras. At the end of the day, I found that for workflows where I needed quicker Aux output controls, I was better off using an ATEM model with
front-panel Aux controls and switching the program output using the software control panel.
Although it’s not perfect for all applications,
the ATEM TVS Pro HD is a very competent HD
hardware video switcher that outperforms many
more expensive models while being priced so
low that it is less expensive than most software
