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:

Try also ffplay to list supported formats for a video4linux2 device:
ffplay -hide_banner -f v4l2 -list_formats all /dev/video2 [video4linux2,v4l2 @ 0x7f8280000cc0] Raw : yuyv422 : YUYV 4:2:2 : 1920x1080 1600x1200 1360x768 1280x1024 1280x960 1280x720 1024x768 800x600 720x576 720x480 640x480 /dev/video2: Immediate exit requested nan : 0.000 fd= 0 aq= 0KB vq= 0KB sq= 0B f=0/0
this one at least list all formats but not their framerates ...

I am not sure about what the following command really does, but it was described to
"Grab and record the input of a video4linux2 device, leave the frame rate and size as previously set:"

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.
