There's nothing "fancy" about a good deck.

Which exact model?
Lots of consumer-end VHS JVC VCRs are really bad. Only the pro/prosumer decks are good.
Very similar to Panasonic: junk consumer decks, nice pro decks.

But for capturing, frame sync seems higher priority than image clean-up to keep a capture card happy.

Not "frame sync", but "frame sync TBC". Not the same.
- Line/frield TBC mostly cleans the visuals/image, some signal cleaning.
- Frame TBC mostly cleans the signal, some visual/image cleaning.
- You need both.

There's a DPS-220 TBC/Frame Sync

Garbage. Broadcaster rackmount units were not designed for VHS sources. Those will choke.
Quote:
For.A FA-300 TBC locally for image cleanup
|
No. It lacks line/field, and is just another rackmount frame unit.

(says it also has DOC feature - does that require an external device's assistance?).

This is a worthless feature. DOC (dropout compensation) was for pro end sources like U-matic, which lacks DOC internally. VHS/S-VHS VCRs already have DOC.

I'm aware that these pizza box broadcast pieces can have worn out caps, and I can recap the things if necessary.

Probably. But caps isn't the issue.

I got an idea to try this equipment flow:
VCR -> DPS-220 in "sync" mode -> FA-300 TBC -> Hauppauge HVR-1265
|
That's not a workflow. The main issue here is the TBCs will clash. I'm actually curious which of those units is worse, and I'm betting the FA-300 is.
Quote:
is an external genlock piece needed for multiple devices if there is only one initial video input?
|
As mentioned, genlock is for syncing external separate sources for broadcasting.

Thanks for any suggestions. Glad to finally join here - and the info on this forum has helped tremendously with past projects.

Glad to hear it.
VHS conversion has a recipe: VCR/camera > TBC > capture card
But not any VCR, any camera, any TBC, any captures card. Specific models know for quality, which have the features needed to do a quality. (Not just "quality" either, but a job at all. The wrong gear = no conversion whatsoever.)
Better gear = less headaches. Whatever money you think you'll save will be spent in lost time. Lots of people just give up, because it's not cooperating with their cheap gear.

This is actually correct, technically.
TBCs fix timing errors.
- The byproduct of line/field based correction = image cleaning.
- The byproduct of frame is signal correction, which thus appease capture cards.
- And again, you need both.

You don't want the FA-300 anyway, it samples at 8 bit 4:1:1

Gah! I didn't even notice that. Yuck!

That refers ONLY to like TBC (frame>frame, or line>line) and NOT complementary (line>frame)

If they are available locally to you see if you could give them a test before you buy.

Nah, with the gear being mentioned here, total waste of time. Many people have already tried this. Between 2010 and 2015, I went through many rackmount TBCs. The only unit that was actually decent was the I.Den IVT-7, and it was fussy. It was actually made to (begrudgingly?) accept consumer sources, not just broadcast, and comes near the end of manufacture of rackmounts TBC.
