If there is so much (consistent) tracking noise and you have no option to recapture it better, you can cut the static away and fill/re-center the picture.
Something like this for example:

Add borders to make the video original size again:

Here's my attempt, using Virtual Dub2-64bit for resizing to 4:3 (assuming it is that), denoising with Camcorder Colour Denoiser and Neat Video (which is a paid plugin), Mercalli (paid-program) for stabilisation and Magix Movie Studio for per-scene cropping (to remove bottom static) and export. File DAR is 1:1 (1440x1026). Bitrate can be cranked up if desired.

Not sure what this means.
The source is small, and there are a lot of artifacts. If you have the tape, perhaps you should capture it again.
Any typical attempt at improving it is a compromise, because when you remove the noise and fuzziness,
you start to also remove the details, and there aren't that many to begin with.
Here's a try using Avisynth and Vdub2
Selur's first example above looks pretty good, perhaps he can encode it for you -
The script is very simple; I tried a few other things, MosquitoNR, Santiag, etc. but it didn't help
Code:vid=lwlibavvideosource("C:\Users\davex\Downloads\ese.mp4") aud=lwlibavaudiosource("C:\Users\davex\Downloads\ese.mp4") audiodub(vid,aud) a=trim(0,848) b=trim(1119,0) a+b # spline64resize(640,480) crop(8,0,-0,-36) hqdn3d(6.5)

Yeah I see. Looks like vsCNR2 is the updated replacement, but the old one
is still good
http://avisynth.nl/index.php/Cnr2 -
Arrgh, I think there's a bug in the vsCNR2 wiki. The example shows "cnr2" but you need to type "vscnr2".
CCD is still making an noticeable improvement after vscnr2. -
I see that. I found it in my vdf archive; it cleans up the chroma noise pretty good, and also stabilizes the saturation.
Good find.
It converts to RGB32, but I don't think doing it once is too much of a hit. -
fwiw, one more variant
Code:trim(0,848) + trim(1100, 1952) crop(8,2,-0,-24).spline36resize(400,300) Dehalo_alpha(rx=2.1, ry=1.6, darkstr=0.6, brightstr=1.0) SMDegrain(tr=5,thSAD=1000,contrasharp=50,prefilter=3,refinemotion=true,LFR=false) Adaptive_Sharpen(0.8) FineDehalo()

QTGMC+TemporalDegrain2+VEAI(upscale 2x + framerate x2)

I do not recommend hq3dn. I used it for a while until I realized that it made dark videos terribly dark. (E.g. a room with the lights off, dark figures, and the bright spots are small light bulbs).users currently on my ignore list: deadrats, Stears555

Code:
convertbits(16).converttoyuv444 QTGMC(preset="slower", InputType=1, TR2=3) <-- but may not be useful (check) TemporalDegrain2(degrainTR=3, grainLevel=2) <-- you can try other values, there is room for improvement here.
Next step VEAI, but this is a commercial software. Upscale 2x + Chronos 50fps + Artemis/low quality filter.
Optionally remove shakes with Deshaker v3.1 (Vdub plugin).
The video would be smoother, but there are a lot of duplicate frames. They can be removed in VDub. -
