Avisynth: Clip is Upside Down and Mirror Image!!

mistermickster · #1 01-13-2004, 10:10 AM

Hi all,

A little help required here please

I read in this thread about placing common routines in a .avsi file in the Avisynth plugins directory, and calling it as a function.

With this in mind, I decided to cut the MA script in half and treat the main process as a function, like so;

Code:

#### 
#
function MAroutine(clip c, int width, int height) {
 
undot() 
Limiter() 
GripCrop(width,height) 
GripSize(resizer="LanczosResize") 
STMedianFilter(3, 3, 1, 1 ) 
MergeChroma(blur(1.5)) 
MergeLuma(blur(0.1)) 
# 
# 

## Linear Motion Adaptive Filtering ## 
# 
# ( Portions from AviSynth's manual ) 
# This will apply variable temporalsoften 
# and variable blur. 
# Both filters are active at all times, and work inversely proportional to the 
# activity, measured from current frame to next frame. 

ScriptClip(" nf = YDifferenceToNext()" +chr(13)+ "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)  ") 

# 
# 
# 

GripBorders() 
#LetterBox( Your_Values_Here ) # Depends on situation. Use MovieStacker! 
Limiter() 

return c
}
# 
# 
## Functions ### 

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

That could then be left alone and I could just amend a small calling script each time, like so;

Code:

(Johnny.avs)
#### 
## Main section and static filters ### 
# 
Mpeg2Source("C:\Movies\Johnny\johnny.d2v") 
# 

width=544
height=576
MAroutine(width, height) 

# 
####

Or so I thought

First problem,

I tried opening the script in Media Player and VirtualDub. Both gave me an error saying that undot contained the incorrect number of parameters. I amended the "function" to include the clip (c) as a parameter.

Second problem,

The movie is now upsidedown and mirror image

Can somebody else give this a try and let me know what I'm doing wrong.

Thnx guys

Regarding the first problem:
Delete clip c, in

Code:

function MAroutine(clip c, int width, int height) {

to

Code:

function MAroutine(int width, int height) {

Still looking for the second error...

I think it's the opposite. A function should always refer to a clip as parameter, start with a filter using this same c, and finish with '"return c".

So try to keep your line "as it" and change the line with undot by "Undot(c)".

The function (clip c, .....

is important!

Just do it like this as I already pointed that out here:
http://www.kvcd.net/forum/viewtopic....ight=maroutine

Code:

Mpeg2Source("D:\mymovie.d2v")
undot() 
GripCrop(width,height) 
GripSize(resizer="LanczosResize") 
STMedianFilter(3, 3, 1, 1 ) 
MergeChroma(blur(1.5)) 
Maroutine()
Gripborders()

And do safe this one to your AVS PlugIns Folder as "Maroutine.avsi":

Code:

#
function Maroutine(clip c) { 
c=ScriptClip(c, "nf = YDifferenceToNext()"+chr(13)+"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)* ") 
return c 
} 

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

Of course you two are right. I've just compared the parameters given to the avsi, sorry

Undot will be the first one claiming the clip name...

Hi guys,
Have I mentioned Incredible comes up with great routines??
I'm using MAroutine for a while and I thinks it's great to turn some good static scripts into MA scripts.
Nice work Incredible!...

incredible · #7 01-13-2004, 05:16 PM

I think the main routine inside doesn't come from me.
I just put that baby in a function, thats all, but thanx anyhow!
