I wasn't planning on capturing the video via HDMI as I thought that was sort of no fly zone rule of thumb for this kind of thing. But, I did a few tests w an "HDML Cloner" which from
Amazon in 2017 for around $100 and records to USB thumb drives in MPEG-4 4:2:0 YUV. The only thing I've gathered so far doing this is the video is a little sharper and less saturated (again, probably more normal) when the VCR's HDMI output is set to upres to 1080(p or i) rather than set to 480i.
I have an AJA Kona LHe and was planning on recording w that from a true S-video feed.
