AVISynth Filters for Filtering old VHS tapes.

[Sartorius48]

I have been using AVISynth for a few years and still cannot get used to all the myriad of filters. New ones seem to be written all the time. It is hard to pick the right one.
I have been experimenting with various filters and scripts.
I capture old VHS tapes via a CANOPUS ADVC 300 then onto the hard disk as an AVI.
I cut it up using VirtualDub - it is easy to operate to remove the noise. I use the DeShaker filter.
I test the scripts using AVSPMod with varying success and I intend to use Sony Vegas Pro or MEGUI to encode it.
I scour the Net, particularly Wikimedia, Doom9 and Videohelp - trying them out.
My question is - is there a bunch of (AVIsynth or VirtualDub) filters that would do the best job?
My VHS has blotchy, unfocused colors, and vague edges. Also annoying horizontal lines that make objects shimmer.
I have solved the problem of cropping (letterboxing) and Trimming.
My videos are quite interlaced.
I find that SeeSaw or Convolution 3D is a start.
Does anyone have any reliable up-to-date scripts that they would recommend? Are there any special arguments for these scripts. I would apppreciate any protocols.
Thanks in advance

No idea where to start. Your workflow seems rather odd (begin with cuts in Virtualub, likely with improper colorspace conversion) then more conversions in Avisynth using filters designed for progressive video, and so forth. Removing noise with DeShaker ?? (it's not a denoiser).

Good idea to begin by finding the reason for "blotchy, unfocused colors, and vague edges" as well as "annoying horizontal lines that make objects shimmer" in your captures.

Why are you cropping?

Sorry. I meant I use DeShaker to stop the Shake in my relative's Video.
I am going to need to be better informed about colorspaces. I began my video editing using MEGUI and used it for cropping and removing tape scratch at the bottom of my videos. Then I wanted to import some AVISynth filters into MEGUI with varying success (crashes). I was configuring MEGUI to x264 and saving it as MKV (x264: ENOEWO_SLOW preset). I then discovered RipBot264 but prefer MEGUI.
Specifically I use MEGUI to crop left, right, top and bottom.
My desire for my final output would be a clear, steady video. The fiobjects in the video I have are very badly defined.
Please find my short video. It is badly interlaced and shaky with scratchy horizontal lines and fuzzy figures.
