Megui not updating
Otherwise, you run the risk of getting some really false readings when you analyze your material. If you know what your doing (or even if you don't), you can use this drop down box to select your preferred resizer. I don't use this option that much, as I prefer to select my own denoiser (since I have tested so many and know which ones I like).The defaults are just fine, but play around with the options if you have some time to find something you like. You are more than welcome to give the four options a spin for yourself.Just test the output script first by playing it and see if the output has any artifacts or anything of that sort before encoding.Most people just use the big rosy button, but if you happen to know the source type and field order, you can greatly speed up the process.It offers 5 drop-down options: This is a quick selection box for loading your favorite Avisynth profile.If you click on the "Config" button, you can see what I am talking about.It's a pretty self explanatory little setup, but if you guys want me to write up a post about it, I would be more than happy too.

Usually Me GUI's recommendations are pretty spot on (except when dealing with really tricky material), and should work fine in most cases.
It's a pretty harmless option, so don't fret over it too much. What this do-hickey does is analyse your input file for interlacing patterns, and suggest proper Deinterlacing/De IVTCing techniques.
I have to disclaim, however, that it isn't always 100% accurate.
It's a fantastic tool, and not just with respect to use with Me GUI.
I (and many others, I'm sure) have used the Avisynth Script Creator to create scripts for their personal use in a number of different situations.
