[Cin] offtopic: Digitize and record Video with A/D USB adapters

[mnieuw at zap.a2000.nl]

Hi Terje,
I have used a cheap chinese USB video grabber to digitise VHS. But I
cannot remember the type.
I used VLC, which worked fine, but OBS should also work. I had loaned
the grabber, and have not tested if Cinelerra-GG could use it directly.
I cannot remember if video and audio showed up as two different devices
or not. If the audio is not a separate device, then I doubt
Audacity can record with it.

The quality of VHS is not that great, well below SD, I did not use a
lossless format. There are several, Andrea listed some he used. But all
those use very big files.

I don't know about the audio quality, it is likely more than good
enough for VHS. But my guess is that a motherboard's A/D is better.
