Geometry refers to whether the objects within the frame are correct or stretched - like my previous example of a circle being oval. Aspect ratio can refer to a few different things, but in this case your aspect ratio at 640x480 would be 4:3 exactly. If you use the script I gave you, it will give you correct geometry, and the geometry will not change even if you crop it again, thereby changing the aspect ratio.
I may be confusing these 2 terms and even resolution too XD
I've read your link and several other sources on aspect ratios and resolution but still, there's something I'm not getting about all this stuff which makes me get confused about geometry, cropping and resolution. Thanks to your link and few other links I looked at now a part of the doubt is solved but still there's still something I don't understand. From my understading, giving the output video the same resolution (e.g. 640x480), depending on how much you crop the output is going to keep the original aspect ratio of the input video or you are going to deform more and more the image in order to keep a specific resolution. If you crop a little (8px let's say), then people won't notice, but if you cut 50px in width and only 2px in hight, then the picture's aspect ratio (?) is going to get deformed... or not? This is what I was trying to ask w

If it's a yes/no answer the one to my question above I'd be happy 'cause is something that is causing me a lot of confusion. If it requires a lot of explanation nevermind I've asked a lot already
Anyway, thank you a lot for all the help you have given me with the script and my doubts, sensei
In order to keep the geometry you'll need to make sure you're doing a good cropping and keep in mind the active area etc... there's quite a bit of stuff behind it, so doing it by hand can be a bit tricky. I suggest you use that site to do the math.
Thank you for the link! I already checked it out.
I've learnt how to use the calculator. Now there's just understanding the concepts behind it left ~_~

Actually that string was only a suggestion rather than an actual recommendation. I meant for you to tweak it. As I wrote it, it'd only be good for de-ringing rather than dehaloing.
Oh, ok! I had no clue about that. I don't know how to tweak that to get dehalo instead of deringing. I'm just getting started with learning avisynth's filters in depth. Until now I just followed guidelines. Can you give me a tip, please?
Ok, and now, the result of the script as of now (using dehalo_alpha):
Ta-da! It looks lovely IMO ^^
Now here's the question... When played at full screen i get this aliasing even though I've put antialiasing in the script. I just want to know if it's natural for the video to get alising when played at full screen, or if there's something I can add to the script to soften the aliasing.
Here are the full screen images of the samples above:
