figured would be of interest to folks here. know nothing about it but looks interesting

The build is based on the MS2130, a HD video and audio capture chip that’s compatible with USB 3.2 Gen 1. We’re pretty sure that’s now called USB 3.2 Gen 1×1, and that standard is capable of transfers at up to 5 Gbps. Thus, the chip can support HDMI at up to 4K resolution at 60 Hz depending on the exact signals being passed down the line. It’s compatible with YUV422 & MJPEG modes and can be used with software like OBS Studio and FFmpeg. The board itself is relatively simple. It features an HDMI In port, an HDMI Out port, and a USB-C port for hooking up to a computer for capture.

If the parts and the time taken to order, build and set up is more than four hours of my time it isn't worth it. Time is money.
The other problem suggested in the link you give is the licensing for some things which makes it a non starter.
However for an electronics geek doing experimental stuff at home it would be interesting.

I know quite a few people who capture HDMI streams using a simple HDM 4K 60p splitter. Cheap and simple. Not all splitters will work, but many do. I know one brand available pretty cheaply from a local electronics/hobby store here in Australia that works flawlessly. Connect everything then turn on the splitter and TV first then lastly power up the capture device on the second output of the splitter and capture... sssh! It even allows capture of HDCP protected stream! :shocked::shocked:
