I discovered that it's better to put all the smoothing filters before the subtitles so that they aren't blurry

Code:
#=====================================================#
# -= AviSynth script by MovieStacker v2.0.0 (beta) =- #
#=====================================================#

LoadPlugin("C:\Program Files\video tools\MovieStacker\Filters\MPEG2Dec.dll")
LoadPlugin("C:\Program Files\video tools\MovieStacker\Filters\DustV5.dll")
LoadPlugin("C:\encoding\textsub.vdf")
LoadPlugin("C:\Program Files\video tools\MovieStacker\Filters\LegalClip.dll")

AviSource("D:\encoding\MOVIES\movie.avi")
LegalClip()
SpaceDust()
TextSub("D:\encoding\MOVIES\movie.srt")
BicubicResize(512, 334, 1/3, 1/3, 1, 0, 638, 352)
AddBorders(8, 73, 8, 73)
LegalClip()

Yeah, that makes a lot of sense, because the subs are computer generated and are solid So no need to filter them

On the other hand, they may be too sharp, and waste a lot of bits. If you smooth them, this bandwith is saved for the video quality.

so sharp subs require more bits than blurry subs?

I think that difference is really neglegible...
I like it sharp

Sharp things require more bits than blurry things, that's why we use smoothing filters to get better compression

As Jellygoose says, with subs the difference may be so tiny that you may prefer the sharp subs (note how I carefully avoided the word negili... err...).
