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/B0...
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
1) It was just an example... 2) If you search you will find... 3) It's only ~8 euros, just grab one and try and thanks to Amazon, you have 1 month to give it back if that does't work or suites you. Other on-line shops may have similar return policies...
(just like the S-video&composite to usb2 converters/grabbers)
did I already say (I suggest you to...) _DO NOT BUY_ inexpensive S-video/composite 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 (?)
I repeat: that was just an example, as a proof of concept, but in this instance, yes, I read from the site (as you may have done already): Specifications: - HDMI resolution: Max input 4K 60Hz - Video output resolution: Max output 1920×1080@30Hz - Video output format: YUV420/JPEG - Support video format: 8/10/12bit Deep color - Support audio format: L-PCM - Support AWG26 HDMI standard cable: input up to 10 meters etc.

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.
Did I say that is was just an example? ;-) -- Saluton, Marco Ciampa
