Grab what you can, add to radarr and you’ll likely get the absolute bulk of them. There may be some odd ones out, and those are the ones I’d rip.

For the rips themselves, what I ended up doing for family tapes is a generic s-video capture device, ffmpeg to rip.

I capture for the full length of the tape, play it, take a peek that everything came in well, and find the end to trim (also ffmpeg).

Then that version I’ll make an archive, and I’ll transcode a copy for media server use.
