Many good points, and I shorten the repeated thread above

<blockquote type="cite">
<pre>FLAC is audio codec, but from what I saw ppl used it with huffyuv for
example on Windows, so main output from drivr should be uncompressed</pre>
</blockquote>
<br>
Of course, my confusion, FLAC is "Free Lossless Audio Codec", which
I never have used so far (remembered Andrea mentioned it).<br>
<br>
Could i.e free, lossless FFV1 (or x265 lossless) be useful "LTS and
crossplatform compatible codecs" to compress 4:2:2 SD and HD video
output for archiving and editing?<br>
So far I have used proprietary ProRes HQ via BM Hyperdeck Shuttle 2,
but an open format is a wishible option. <br>
(Playback S-Video via TBC and converted to DV PAL (4:2:0) has
visible less colors, which also may be due to Datavideo bult-in the
A/D converter in the recorder..)<br>

<br>
2) AVerMedia CL311-M2<br>
This looks to be a newer, more professional and > US $300 costly
PCIe video capture card that supports both analog video, full HD(MI)
video and more.<br>
Beyond Windows support, there is a Linux Driver (2.0.8) for Ubuntu
20.04/18.04/16.04, kernel 5.4.0-4.15.0, TegraOS kernel 4.4.0,
Support users to complie driver by themselves.<br>
While the first CL311-M1 included a S-Video connector on its
backplane, the M2 version apply a cable dongle and supports 8 bit
colors, 4:2:2 uncompressed format..<br>
(That is, not unlike BM's (previous) Intensity Pro video grabber
card)<br>

<blockquote type="cite">
<pre>- I would avoid plug-in cards, you are completely dependent on the
manufacturer's support for Linux drivers. On the other hand, USB
grabbers usually follow standard USB audio/video rules, and almost
always work.</pre>
</blockquote>
-------------------<br>
<blockquote type="cite">
<pre>Your argument is valid for drivers in Linux. The problem with the USB
drivers and Linux;
- Linux supports a single endpoint per device, when the device needs two
independent drivers this causes a problem. For example V4L + libusb with
an ATEM.</pre>

3) AVerMedia CU511B <br>
This full HD and SD Capture Box, 8 bit 4:2:2 with USB 3.0, could
possibly be an interesting external counterpart to the CE311-M2 PCIe
capture card mentioned above.<br>
However I would expect it costs at least as much; possibly therefore
my search didn't find it for sail. <br>
According to the latest datasheet (DS_CU511B_EN_21060630.pdf, 1.5
MB), Windows and Linux driver support is included (and possibly
required?) as<br>
•Linux Services<br>
•Support Linux kernel 2.6.14 version and later based on V4L2 &
ALSA framework<br>
•Driver customization service by request<br>
