On last Friday Blackmagic Design has announced a new, small, 4 channel HDMI switcher : https://www.blackmagicdesign.com/media/release/20190913-01
Looks. Very. Promising.
Because you will be able to preview a single source in the same time (there is no multiview preview option at the moment) on Blackmagic Design’s ATEM Mini Switcher I thought some people needs a workaround for this cheap mixer / switcher.
I bet, this device will be very popular.
Also I don’t know (yet) if Blackmagic Design is planning to add a multiview feature of their new device, or they already maxed out this little box.
Let’s see what you’ll need (and probably you already have some of these gears):
You’ll have to find:
up to 4 BMD Micro Converter BiDirectional SDI/HDMI
up to 4 SDI cables (from BMD Micro Converter’s SDI out to Decimator DMON-QUAD’s SDI in)
up to 4 HDMI cables (from BMD Micro Converter’s HDMI out to ATEM Mini HDMI in)
one preview monitor (like Lilliput’s A7 )
in this case you’ll have SDI and HDMI inputs as well for each channel
+£600 a bit expensive solution for a £300 switcher
Probably you have some old Atomos device on your shelf, like Atomos NINJA2, Atomos NINJA Blade or similar with HDMI IN and HDMI OUT connectors. If so then this will be a cheap and useful solution.
What you’ll need:
up to 4 Atomos device
up to 4 HDMI cables
You will be able to record and monitor the sources separately
Display resolution / quality is low
Lack of 50p/60p recording in 1080p
Of course the above mentioned limitations are not true, if you have an (or some) Atomos NINJA V, but in this case this solution will be more expensive than others.
up to 4 small 5" or 7" monitors, like Lilliput’s A7 with HDMI IN and HDMI OUT (HDMI Loopthrough) connectors
up to 4 Manfrotto PIXI Mini Tripodsup to 4 short HDMI cables
You can see nice, full HD image from each source
These addition gear’s cost around £500
Please do not forget, you only have two options for outputs: 1. Program on HDMI OUT & USB-C 2. Program on USB-C, Preview on HDMI OUT
