For archiva purposes I'd suggest to stick with a lossless compressor. Any lossy compression might influence future restoration attempts. Let alone YV12 chroma subsampling.
MagicYUV has better speed...

This is a good thing.

Nearly all digital noise reduction circuits built into consumer electronics are much worse than you can do nowadays in software.

Thus the NR from a VCR or DVD-Recorder...

Even if I might repeat myself here:
The PAL-Version of the ES-10 does no denoising, when NR is set to "off". I did thorough tests. No temporal or spatial smearing at all.
If the ES-10 would have...

make a comparison of gtgmc() with bob()

I suspect that the fields are not aligned.
That's nothing QTGMC is going to fix for you.

It was very easy to remove the entire head rum by just removing one skrew.
Then I put ONE drop of very light oil on the shaft.

interlaced YUV4:2:0 is really horrible unless we upsample it with "algorithm guessing" (like you name it) to YUV4:2:2 / YUV4:4:4.

YUV4:2:0 has been chosen in the past, because analogue...

I agree, that the kind of sampling (nearest neighbor / average) is dependant on the implementation.
I think the best would be, to mention both kinds of sampling in the guide.

This simply is not true. The math is correct.

What you mean is: Lot's of implementations are incorrect!
Most chroma-upsamplers are doing it wrong by just

In progressive domain 4:2:0 chroma subsampling might be okay.

But IMHO, 4:2:0 in interlaced domain is equally bad as 4:1:1.

This page explains 4:2:0 and interlacing quite well:...

Over the years I settled with VirtualVCR. It is the easiest to use for me and solves the A/V-sync issues.

The problem with the filters you're using is: they are just motion adaptive but not motion compensated.
Thus you're wasting an enormous potential amount of image quality gain.
