AviSynth script to increase picture quality of VHS to DVD?

[VideoFanatic]

I have VHS wrestling videos which were converted to DVDs. I then demuxed the DVDs into MPEG 2 files (some of which are 704 x 480). I use this AviSynth script:

Mpeg2Source("I:\New\1 = Test files\clip 704.d2v", CPU=6)
AddBorders(8, 0, 8, 0)

The "CPU=6" deblocks it so there is no pixilation whatsoever anymore and it also does pretty good noise reduction where it removes the background flicker and other noise. However it does blur the picture slightly. If I add the following script to the above script then it gives a perfect picture completely removing all forms of noise, it gives better black levels and it doesn't blur the picture:

McTemporalDenoise(settings="medium", interlaced=true)

However McTemporalDenoise takes over 20 hours with a 1 hour 15 minute file. Is there any script which will perform the same function as the above McTemporalDenoise script which takes 3 hours or less?

I have VHS wrestling videos which were converted to DVDs. I then demuxed the DVDs into MPEG 2 files.

Could someone please suggest a script that will fix the colours along with hue, saturation, brightness, and contrast and anything else like that and good white and black levels. Some files have dull colours, others are fine. I need a script which I can use on any of my videos which will normalize the colours so they look normal on all my videos. If the colours are already fine in some of the videos then the script should have no effect. Would the following script do that?: ColorYUV(autogain=true)

What exactly is luma and chroma by the way?

The script must take 3 hours or less with a 1 hour 15 minute file.

The picture in some of my videos moves up and down every several seconds. Is there any way to fix that with a script? If so, could you please advise the best script to use.

The script must take 3 hours or less with a 1 hour 15 minute file.

I saw the power of AviSynth videos such as this: http://vimeo.com/11133342. It looks like the video was unblurred so it looks like a DVD. Are there any filters that can do that (or get as close to DVD quality as possible) with VHS videos which were converted to DVD?

I would be working with an MPEG 2 file that I demuxed from the DVD.

I already use this script which deblocks and removes the noise but it doesn't increase the picture quality.

Mpeg2Source("I:\New\1 = Test files\clip 704.d2v", CPU=6)

I know there are scripts that sharpen the picture but I don't know which to use and what script I should use.

The script must take 3 hours or less with a 1 hour 15 minute file.
