Script and Time?

[NLPguy]

Hi folks,

I'm using two AviSynth scripts, posted below, to improve/clean the video of many old VHS (NTSC) tapes that I have. It has many horizontal waves (lines) or fixed lines on the image.

I'm capturing VHS tapes with a Panasonic AG-1980 videotape. Also, I'm using a DVD Panasonic DMR-ES10 to pass through (with all the filters 'on') aiming to strike as many horizontal wave as possible.

My PC is an AMD 8350 4.0 Ghz 16GB is taking 6 hours to run the script. And my laptop - an Intel Core I7 2630QM 2.0 Ghz 8GB is taking 20 hours to run it.


So, please:

Do you know why is taking so much time to execute the script using the Core i7 laptop?

Is there some way to decrease the 'process time' modifying the script below (trying to keep the quality output)?


Thank you very much!
