Hi guys.
Im trying to encode a divx. But where in the avs file can i add a line or something so that the borders at the top and bottom are deleted?
This is the info gspot shown:416x176 (2.36:1) [=26:11]
How to get it 4:3?
Hope someone can help me.

You can open the AVI file though Virtual Dub, the go to filters and add a filter then after that crop it and see how much it takes to crop it, record each boarder, then place it in the avs script like show here, http://www.avisynth.org/index.php?page=Crop Crop(left,Top,Width-Right,length-bottom). Then place your filters like show here http://forum.doom9.org/showthread.ph...threadid=64253 .

Don't bother with that ! Gripcrop do an automatic "border removal" before computing the resizing parameters. It can fail if the borders aren't truly black.

Aren't these borders the ones add by the "overscan" parameter ? They are normal !

And you say "smurf" but did you use the correct settings for source_anamorphic and dest_anamorphic paremeters ?

Which "Gripcrop" line did you use ?

Well this is my avs:
## DLL Section ##
#
LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\MPEG2Dec3.dll")
LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\GripFit_YV12.dll")
LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\STMedianFilter.dll")
LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\asharp.dll")
LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\unfilter25.dll")
LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\undot.dll")
LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\VSfilter.dll")
#
####

## Defined Variables and Constants ##
#
MaxTreshold = 1.50
nf = 0 # Current frame.
#
####

## Main section and static filters ###
#
AviSource("D:\skvcd\Grease.avi")
#
ConvertToYV12()
undot()
Limiter()
asharp(1, 4)
GripCrop(352, 288, overscan=2, source_anamorphic=false)
GripSize(resizer="BicubicResize")
STMedianFilter(3, 3, 1, 1 )
MergeChroma(blur(MaxTreshold))
MergeLuma(blur(0.1))
#
#

## Linear Motion Adaptive Filtering ##
#
# ( Portions from AviSynth's manual ) - This will apply temporalsoften to
# very static scenes, and apply variable blur on moving scenes.
# We also assign a variable - and this is why a line break is inserted:

SwitchThreshold = (Width<=352) ? 4 : (Width<=480) ? 3 : 2
ScriptClip("nf = YDifferenceToNext()"+chr(13)+ "nf >= SwitchThreshold ? \
unfilter( -(fmin(round(nf)*2, 100)), -(fmin(round(nf)*2, 100)) ) : \
TemporalSoften( fmin( round(2/nf), 6), round(1/nf) , round(3/nf) , 1, 1) ")

#
#
#

Textsub("D:\skvcd\Grease.srt")
GripBorders()
#LetterBox( Your_Values_Here ) # Depends on situation. Use MovieStacker!
Limiter()

#
#
## Functions ###

function fmin( int f1, int f2) {
return ( f1<f2 ) ? f1 : f2
}

#
###

To be more exact: My source is not 4:3 so when i play it it has a black line above and beneath the movie.

---------------------
Border
---------------------

movie

---------------------
Border
---------------------

And i was wondering if i could make it full screen.
But what do i have to change in the avs? Im using tok.
And also i tried to encode as you said, but the movie was with borders and just like a photo negative.

But the borders aren't in the source, are they ?

If not, you can't remove them (as they do not exist). And you can't do a fullscreen movie form a bordered one without cutting the sides (and so, loose some picture).

And DL also GSPOT to analyse the true size of your video. These borders aren't in the source, I'm pretty sure about this.

You see, your source is widescreen, that's the player that put the black borders to fit the picture in your 4:3 monitor !
