Capturing is very binary in nature.
- you either have excellent captures, either flawless or near-flawless
- or you have bad capture, with multiple problems that make the video look nothing like what existed on the original tape
The only factor between the two is the proper tools (proper hardware). It has nothing to do with "all-out" or "top quality", but merely the presence or absence of the tool.
- quality VCR (ie, not something ever sold in Walmart or Best Buy)
- some form of TBC is required
- quality capture card -- not something that capture to compressed "MP4" (H.264), not Chinese HDMI adapters not meant for capture, not cheap Chinese USB cards like Easycaps/"grabbers"
When it comes to video capture, you can:
- buy proper gear, for a proper job
- not buy proper gear, and get crap quality
There really is no middle ground.
- There's not some sort of super-secret cheap method out there (conspiracy stupidity).
- At best, you'll have to hunt for months or years to find quality hardware mispriced, but it won't be online (offline auctions, thrift stores, estate sales -- but also noting it may be broken junk).

non-TBC JVC S-VHS

Capture Card: ION VIDEO MKII

This card should be fine. It's has variant components from known-good cards. But the bigger issue is drivers, hence why not discussed more. It should also be considered Windows-only, the Mac aspect is a mess.

TBC: SLYVANIA DVD RECORDER

This is not a TBC of any kind.

Interseting. That capture card generally does not work reliably in Win10.

Deinterlacing: Yadif Double Framerate - Top field first
|
By "double", you mean 29.97fps/59/94i > 59.94p (or 25/50 PAL), correct?
Quote:
Upscale
Software: VirtualDub2
Resize: Either 1440x1080 or 1920x1440
|
Why? That just lowers quality.

Exporting Compression: x264 8 Bit H.264/MPEG-4 AVC Codec

Why so compressed?

Honestly if I seem like a joke on this thread, I just started to learn how to get REALLY good captures. I started off using Easycap and OBS in 2021 
|
"Good" is not the right word. That method just decimates quality. VHS tapes don't look that bad.

Agree.

If you don't want to upgrade your hardware, QTGMC deinterlacing should beat Yaddif 2x.

Why? Yadif 2x is still just inferior Yadif to QTGMC.

I can't say I've heard much about the Ion, though I'd say the most interesting part about the Ion it is that it's both Mac and PC compatible (though unsure if modern macOS will play nice with those drivers or not).
|
It's not interesting whatsoever. It was made during OS X 10.5, and failed in a few versions. Beyond that, the software choices all suck.

Also don't know about the Sylvania DVD recorder - if that can output 480i through HDMI
|
No NTSC DVD recorder/player does this (output is always deinterlace garbage), and few PAL do either. This is not a viable capture method.

but doesn't look like you plan to use a frame TBC anyway. Frame TBCs generally aren't going to improve the visual quality of your output (if you aren't seeing obvious dropouts in the captured video), but could remove vertical jitter if you are seeing that.
|
Some form of TBC is required, or frames will drop. The weakest form is certain Panasonic DVD recorders (not just any random recorder), with a strong+crippled line TBC and non-TBC frame sync. It's not perfect, there are artifacts and issues, but better than nothing.

I can't say I've seen too many examples of vertical jitter on the output of a DVD recorder though.
|
Oh, those exist. I have sample captures somewhere, especially from ES10/15 output (as I was focusing on the many errors of those machines, and why the half-baked idea of it being a "TBC replacement" is ridiculous).

If you aren't seeing dropped frames in virtualdub with your setup
|
Noting that you can disable dropped frames reporting if not careful, so this can mean nothing until settings are confirmed.

then the benefit of a full frame TBC is highly questionable to me and probably even a little bit detrimental
|
Ridiculous.

as it has an extra analog to digital and digital to analog conversion step that'll cause some degree of loss (which is hopefully not perceptible with an ideal TBC).

This is too often overblown, often by those that don't understand what is happening. "
It makes a tiny 1% change, maybe, so it's just as bad as a 99% change by not using one at all." -- That's so insane to have the sort of mindset. 1% potential (A>D>A) is not "the same" as 99% likely (by using nothing).
