Any filter will affect final file size.
Basically, the heavier you do filtering, the smaller the final file size.
But the heavier the filtering, the more details you will loose.
So you have to experiment with filters to find out the "optimal" tradeoff between quality and final file size

Code:
undot() 
asharp(1, 4)
STMedianFilter(3, 3, 1, 1 ) 
MergeChroma(blur(1.5)) 
MergeLuma(blur(0.1))
TextSub("C:\abc.SRT")
this is my script.
using this script, the final file size was bigger than it was expected.
so, some filters makes your output file bigger.
i would like to know which filters do that.

zenks
gracias

Ah, you see, the sharpening AND your subtitles will make your final size larger.
Sharp edged will always increase your final file size
But if you don't use a script, with the same CQ value you used as reference, your final size will always be larger than if you don't use a script.
