The thing is: the analog to digital converters _and_ the digital grabbers
inside cheap pal/ntsc to usb2 are a crap. If you want a really good
quality conversion you have to open wide your wallet and buy a really
expensive grabber just to be sure that it has inside a good (but not so
expensive in itself) analog to digital converter.
... or use a cheap external one like this (just an example):
https://www.amazon.com/ZHIYUEN-Adapter-Universal-Converter-Consumption/dp/B07WTV8FGF
More documentation is needed ;)
The requirement was 8-bit color depth and video format (sampling) 4:2:2
throughout the workflow.
The SCART to HDMI A/D converters I've searched fast on so far had
missing information about this (just like the S-video&composite to usb2
converters/grabbers)
and to capture use one of these:
https://www.amazon.com/IPXOZO-Video-Capture-Card-USB/dp/B08YRWB7VD
The sample grabber supports Video output format: YUV420/JPEG and video
format 8/10/12bit Deep color (?)

these are just examples, (I do not work for Amazon! ;-) I picked them
randomly and they _SHOULD_ work, but I cannot be 100% sure, never tried
those in particular... it is just to explain the principle of this
method... that you should give it a go... it's not such a great expense.
Please note that if you want a pass through usb video grabber (useful for
example to grab games) you have to spend a bit (5xtimes!) more for a
device with input _and_ real time output.
