Settings for 1080p MP4 files?

Hi, I have always used 720p default MP4 setting and I like the size that it produces. Today I have been experimenting with 1080p custom settings, but the files turn out to be really huge :( Does anyone know what setting I should set it to? 

I recorded my video in 1920 x 1080.

Below is the setting that I used for my custom 1080p setting:
Frame rate: Automatic
Keyframe every: 5 seconds
Encoding mode: Quality (100%)
H.264 profile: Main
H.264 level: Auto 
Audio setting: 128 kbps 

So here are a few questions that I hope someone can answer. Thank you in advance.

1) Is it because I set my quality to 100%, so that my final file size is huge? 
How much of a difference does a 100% vs 50% quality have? To be honest, I can't tell the difference in quality between my default 720p and my 1080p (the only difference I can pick out is the dimension size and that is all >.<") 

2) What setting should I use to still keep 1080p but with small end result file? Or is it not possible? 

Here is the size comparison for a file that is 2 minutes and 6 seconds long (I used clip speed increased to 300% if that makes any difference o.O). 
720p default setting, file size =  42.2 MB 
1080p custom setting, file size = 2.47 GB 

I upload videos to YouTube. 
Thank you.

Try first an output of your original video in 

1344 x 756
FPS: 30
Quality: 55

Check the quality and inform here...

and then, work over this result to reach 1080p

The difference between Q 100 & Q 55 is not significant.... only big size at the end.

Did you try the suggestions from lito-soft here? If so, how did it turn out?
