Solid kit!

I do something similar, but slightly different hardware. My VCR is a fun Panasonic that has VHS, DVD, and FireWire for minidv (I still have my minidv camcorder, though I may give it to my oldest who is interested in movie making).

DVD and FireWire inputs come out HDMI and component, but anything from VHS sources is composite or s-video only. So that output goes to an AJA D5D for SDI out, which goes to a black magic decklink for capture. HDMI goes to an Inogeni 4KXUSB3 for reference, I still rip DVD’s here and there, usually oddballs I’ve picked up at garage sales that are worth keeping around on my NAS.

Its mostly a manual operation though, would love to see (an appropriately redacted version of) your capture script! Right now I switch my (not really, but kind of) KVM for my servers over to that machine, and start things off through the GUI.

The script is nothing to write home about at the moment, with most of my time being spent just dialing it in for performance given the age of the Thinkserver. I feel that’s pretty squared away, so the next step is updating it to accept args for things like fps, resolution, etc.
