It's been quite a while since my last post, but I've been keeping up a bit in the background .......

In the past, we had some posts about capture devices, some few standalone or pcie based, but most usb of course. After earlier S-video to DV capturing (which was in 8bit 4:2:0 using Datavideo DN300), my plan has been to recapture all my S-video tapes to 10bit 4:2:2 in Prores LT for the final archive. In fact I tested this 10 years ago for 5 Hi8 tapes (which still work using ffmpeg) using a Blackmagic Analog to SDI mini-converter and a Hyperdeck Shuttle-2 SSD recorder.

Some months ago I tried to resume this capture project, but had to conclude that the BMD converter didn't work. I ordered a new one, 2nd gen (EOS), but unfortunately its new chips seemingly require a studio-quality video signal. The Shuttle-2 didn't get a valid signal to record, even though it works perfectly fine when recording HD video from my HDV camcorder via HDMI.

So at last I had to give up on this BMD analog route. And I don't wont to trust Blackmagic Design Intensity Pro 4K on Linux -- a card I previously mentioned in an old post https://tinyurl.com/2nuj7hfk

There is however another option, —costly, yes—for Linux that I was not aware of and therefore didn't mention in my old post above Magewell Pro Capture Aio - One-channel HD capture card But I have yet to find user posts confirming it is capable to record SD video in 10bit 4:2:2 with v4l2, and especially on openSUSE Tumbleweed-Slowroll.

This is pcie device ... I think "recently" some kind of thunderbolt/usb4 external boxes for pcie devices appeared ... My best idea (apart from buying it from sources allowing return without penalty) is to see if external pcie enclosure can be connected to your more portable laptop, and try to go to physical place where you can assembly whole setup, including source . Some kind of linux user meetup, may be?

Any tip or thoughts about how risky this Magewell option may be with regards to success or failure ?
