So I have received the ms2130 HDMI-USB3 capture card.
The A/D AV converter & SV-HDMI/adapter is not received so
far, and I have not avialable my HDV camcorder (on service)
to output HDMI video stream with.
Yet, I have initially run some verification tests on the
ms2130 HDMI-USB3 UHD capture card alone, for what they are worth.
As "UHD" (and/or USB3) is mostly generic used to identify
this card (while ms2130 almost not), the some output is piped
and stripped with grep "UHD".

As the above doesn't list any 1920x1080 resolution, I wonder
if it list just format for the usb2 webcam and not for ms2130
capture card?
Yeah, looking at how webcam listed first it makes sense. Try to
instruct v4l2-ctl to use another device? (my guess it will be
"-d" switch but I can be wrong! Manyal or "--help" output is
better guide ..)
Be aware that "v4l2-ctl --list-formats-ext" was the same (I think)
as used for the previous ms2109 Hama card, and I thought formats
for all connected devices were listed then.
Obviously there is a default (or first device) used, when no
device is specified, so thank you for the tip.
By help of google and "superuser" I found out that actually both
"-D -d /dev/video2" are needed to get both frame sizes and fps listed:
v4l2-ctl -D -d /dev/video2 --list-formats-ext

try 30 fps instead of 60?
Like this?
But shouldn't a 422 and not a 420 output format be created?
it seems in some cases ffmpeg not geared towards preserving most
information, just picks up most commonly defined/first pixel format.
Try mpeg2video as output codec, and/or specify pixel format (pix_fmt)
more explicitly before output's filename? Also you can try 'copy'
video codec and meet absolutely enormous test file.
