Putting video noise filters before the Subtitles
 
I discovered that it's better to put all the smoothing filters before the subtitles so that they aren't blurry 8O :lol:

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 8)

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... 8)
I like it sharp :wink:

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...).
