I'm using SKVCD with a 16:9 DVD cartoon. I have a border on the left side, no matter what TMPGEnc settings I use (full screen, center, etc). How do I crop this area out. The other three sides are fine.

The size settings are from MovieStacker.


## DLL Section ##
LoadPlugin("c:\video\dlls\MPEG2DEC3.dll")
LoadPlugin("c:\video\dlls\gripfit_yv12.dll")
LoadPlugin("c:\video\dlls\unfilter_2.5\unfilter.dl l")
LoadPlugin("c:\video\dlls\stmed_2.5a\STMedianFilte r.dll")
LoadPlugin("c:\video\dlls\asharp.dll")
LoadPlugin("c:\video\dlls\undot.dll")
LoadPlugin("c:\video\dlls\decomb510.dll")

MaxTreshold = 1.50
nf = 0 # Current frame.

mpeg2source("h:\xx\xx.d2v")

Telecide(order=1,guide=1,post=2,vthresh=25)
Decimate()

undot()
Limiter()
asharp(1, 4)
BicubicResize(320, 318, 0, 0.6, 0, 2, 720, 476)

#GripCrop(352, 480, overscan=2)
#GripSize(resizer="BicubicResize")

STMedianFilter(8, 32, 0, 0 )
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) ")
#
#
AddBorders(16, 81, 16, 81)

#GripBorders()
#LetterBox( Your_Values_Here ) # Depends on situation. Use MovieStacker!
#LetterBox(0, 0, 16, 16)
Limiter()
#
#
## Functions ###

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

Hi nicksteel:
the settings are with resize=2.
Depending on film, and more important on TV, sometimes with resize=2 I see a bar in the left side. Try with resize=1 (but the file will grow), or even play with addborders parameters (I havenīt tried this last one, is just an ).

Hi Nic,

digitall.doc is right, cause the calculation of your resize parameters and the values of black borders as pixels which will be added afterwards seem to be ok. But don't just "play" with the addborders() values! They have to be exact calculated in Moviestacker or FitCD! Cause if you just change them manually by trying , the final size won't match a legal resolution
You only can "play" with the settings of Letterbox(), cause Letterbox() only overlaps black borders and doesn't add black borders as "add"borders() does

Do you have this border in your source ?
If yes use gripcrop, it will remove it before the computing the rezise parameters.

No bar on source. Same results with Gripcrop. I'm going to try Letterbox() adjustments. Never saw anything like this before from a DVD.
