It looks easy...Did you read about it at:

obviously

because of that I'm not very practice with pc

[jagabo]

fart filename.avs #reversibleColorMatrix# colorMatrix(mode=\"Rec.709->Rec.601\")

Replace "filename.avs" with the name of the file you want to change. And, of course, the usual path name syntax applies.

Cats converting video ... programs called "Fart" ...

I can't tell if this place has changed massively in the seven years since I last logged on, or if it's business as usual just with different words.

...oh hey that actually looks quite useful, and it's not just linux-only either... *downloads Fart_win32.exe*

7 years??? What made you log in?

fart filename.avs #reversiblecolormatrix# colormatrix(mode=\"rec.709->rec.601\")

thankssssss :d:d:d:d:d:d:d

[marcorocchini]

jagabo, for kindness: your line as "standalone" work. But when I try to insert is in a batch like this

@echo off
if exist v:\automazioneclip\system\tempOut1.bat del v:\automazioneclip\system\tempOut1.bat
setlocal enabledelayedexpansion
c:
cd\
cd volumes
set "parentfolder=%CD%"
for /r . %%g in (*.avs) do (
  set "var=%%g"
  set var="c:\volumes!var:%parentfolder%=!"
  del out.txt
  echo V:\automazioneclip\system\fart.exe !var! "#VisualDeinterlaceApplicabile#" "bob().SelectEven()">>v:\automazioneclip\system\tempOut1.bat
  echo V:\automazioneclip\system\fart.exe !var! #reversibleColorMatrix# colorMatrix(mode=\"Rec.709->Rec.601\")>>v:\automazioneclip\system\tempOut1.bat
  )
  v:\automazioneclip\system\tempOut1.bat
  del c:\volumes\tempOut1.bat

in the target .avs (!var!) I get this bad result

colorMatrix(mode="Rec.709->Rec.601"

this is missing of a ")". The correct result should be

colorMatrix(mode="Rec.709->Rec.601")

maybe this happen because the entire line have the ">>" attached:

echo V:\automazioneclip\system\fart.exe !var! #reversibleColorMatrix# colorMatrix(mode=\"Rec.709->Rec.601\")>>v:\automazioneclip\system\tempOut1.bat

do you know if there is a way to resolve so that the final result is

colorMatrix(mode="Rec.709->Rec.601")

thankss

Can't duplicate your problem. Try escaping the > in rec.709->rec.601.

Escape ) to ^)

escaping the > in rec.709->rec.601? I cannot undestand

ahhhh cat

[marcorocchini]

echo V:\automazioneclip\system\fart.exe !var! #ColorMatrixReversibileDa709a601# colorMatrix(mode=\"Rec.709->Rec.601\"^)>>v:\automazioneclip\system\tempOut1.bat

I see why I couldn't duplicate the problem. I was testing only at the two "echo" lines in a batch file (because it was too much trouble to modify the entire batch file). But it looks like the problem is that the close parenthesis on the second echo is being interpreted as the end of the "do" loop.

[_Al_]

parentheses are always a sort of trap in batch script one way or the other, better always call a function, just submerge it down a few levels if needed, it does not matter, batch keeps track of it, having hefty number of them, it actually clears things up not complicate them as one would think, those calling functions just get out of the way to the bottom of the script. It clears things up. ...But every calling function should always have an info what kind of file is that argument though, like in this case avisynth script

for /r . %%g in (*.avs) do call :temp_BAT "%%g"
.
.
.

:temp_BAT <avisynth script>
set "var=%~1"
set var="c:\volumes!var:%parentfolder%=!"
if exist v:\automazioneclip\system\tempOut1.bat del v:\automazioneclip\system\tempOut1.bat
V:\automazioneclip\system\fart.exe !var! #ColorMatrixReversibileDa709a601# colorMatrix(mode=\"Rec.709->Rec.601\"^) >>v:\automazioneclip\system\tempOut1.bat
V:\automazioneclip\system\tempOut1.bat
del c:\volumes\tempOut1.bat
goto :eof

yes yes yes he is my friend

[marcorocchini]

jagabo please help: now I need to do the inverse operation

if the inputfile.avs have a string callded:

colorMatrix(mode="Rec.709->Rec.601")

this string have to be replaced with

#ColorMatrixReversibileDa709a601#

I have do many proof but I cannt find the solution

how can I do? thankss

[jagabo]

Sorry, I deleted all the files I was testing with. Can't you just reverse the order of the two arguments?

[marcorocchini]

yes but strangely don't work.

AH no, maybe it work

please jagabo I wonder this: please consider this 3 .avs script

script 1:

LWLibavVideoSource("C:\Users\Administrator\Desktop\Nuova cartella (4)\IMX.MXF")
crop(0,32,0,0)
IResize(1920,1080)

script2:

LWLibavVideoSource("C:\Users\Administrator\Desktop\Nuova cartella (4)\IMX.MXF")
crop(0,32,0,0)
colorMatrix(mode="Rec.601->Rec.709")
colorMatrix(mode="Rec.709->Rec.601")
IResize(1920,1080)

script3:

LWLibavVideoSource("C:\Users\Administrator\Desktop\Nuova cartella (4)\IMX.MXF")
crop(0,32,0,0)
colorMatrix(mode="Rec.601->Rec.709")
IResize(1920,1080)

Where IMX.MXF is s SD video file BT.601 colormatrix.

In the 1 case it is loaded by svisynth "as is" (only SD-->HD resolution converted), but colormatrix keep 601
In the 2 case, the colormatrix correction have to be the same charateristics of the 1 because was bring from 601 to 709 and successively from 709 to 601. So colormatrix remain 601

In the 3 case, colormatrix is converted from 601 to 709

I wonder, if I use the case 2 in place of 1, the cpu of my pc is it subjected to an increased workload respect the case 1? or does not change almost nothing respect the case? Is there a loss of quality between case 1 and 2?

[sneaker]

CPU load will increase with each ColorMatrix() instance.

[jagabo]

I wonder, if I use the case 2 in place of 1, the cpu of my pc is it subjected to an increased workload respect the case 1?

Of course. If you run up a flight of stairs then back down you're back where you started but it took time and you expended energy.

or does not change almost nothing respect the case?

You've just wasted CPU time and...

Is there a loss of quality between case 1 and 2?

The conversion is not lossless. So yes, you've lost quality, though you may not be able to see it. And ColorMatrix clamps super-blacks and super-whites by default. So you will lose those if there are any in your video. Why bother asking a question like this since you can test it yourself very easily?
