Avisynth Help!!

[ocelot]

I already read some guides but sill I have some questions Iam using FitCd
and my script look like this:

# -= AviSynth script by FitCD v1.1.2 =-
#LoadPlugin("D:\PathOf\AnyPlugin.dll")
AviSource("F:\Red Dragon\test.avi")
BicubicResize(480,288,0,0.6,10,0,620,272)
AddBorders(0,96,0,96)
#Trim(0,3646).FadeOut(150)

I tried to resize and my first question is what is crop good for and what b and c parameters are??
The second thing is I tried to resize my NTSC file(640*272) to 480*360 but it seems to be impossible cause when I resize to 480*288 or 480*304 my destination in FitCd is always 480*480 so what is the difference between this two resolutions and how can I resize to 480*360??
And is it a quality difference if I use FitCd or write my own script something like this:


LoadPlugin("c:\mpeg2dec.dll")
AviSource("F:\Red Dragon\test.avi")
BicubicResize(480,360)
#Trim(0,3646).FadeOut(150)

Sorry I know lot of questions but I would appreciate your support
Thanks!!

I basically have the same question ocelot.

Can you list all the tools and instructions you used up to point where you are? Thanks!

Well I use CCE 2.66, FitCd and Avisynth 2.05 dll. Read this thread http://www.vcdhelp.com/forum/viewtopic.php?t=112705

your destination must be 480*480 for SVCD(NTSC)
this is the only valid SVCD resolution. what you can do is addborders to make the resolution correct. Use second script you posted, but with one addition:
LoadPlugin("c:\mpeg2dec.dll")
AviSource("F:\Red Dragon\test.avi")
BicubicResize(480,360)
addborders(0,60,0,60)
#Trim(0,3646).FadeOut(150)

http://www.avisynth.org/index.php?page=Resize
--this should answer your question about b and c values

AHHHHH some things seems to be clear now Thanks!!!
But still I dont know what cropping is for. Is it only necessary if you want to make your movie resolution smaller for example 480*480 to 320*120??

Cropping is primarily used to cut off the captured letterboxed black borders so that they can be replaced with PERFECT black borders, in increments of 16. Also to cut off the overscan area and any edge errors usually associated with VCR playback.

BTW, on your resize, I would NEVER resize upward, just add bigger borders.

I wouldn't necessarily say that...it depends on how big you want your borders to be.
I've resized upwards w/bicubic, and have gotten excellent results.
I prefer that to having the borders take up half the screen

Yes definitely it is. Although I use to trust my eyes more than a "robot" You kvcd guys have really good ideas sometimes.
BTW, thanks for excessive prediction script testing.

Thanks Truman
As SansGrip said the other day: "Things are pretty chaotic right now"
That's all the stuff going on at KVCD.Net. Too much development and people are lost . Eventually we'll get things organized, and the big picture will be clear 8)

Is this a right script for removeborders??

# -= AviSynth script by FitCD v1.1.2 =-
#LoadPlugin("c:\mpeg2dec.dlll")
#LoadPlugin(C:\removeborders.dll)
AviSource("F:\test\test.avi")
Removeborders()
BicubicResize(480,384,0,0.6,8,0,624,304)
AddBorders(0,96,0,96)
#Trim(0,2036).FadeOut(150)

If yes it doesnt work for me.

Hi ocelot,

RemoveBorders() is not yet finished . It only does that. Removes the borders. So far, it seems to be accurate, so just keep an eye on that thread for future development

Ok thanks!!
And why is it necessary to give the last two values in the bicubic parameters??-> Bicubicresizer(..,..,..,..,..,..,670,352)
I think its the source value but is it necessary the write them??


Thanks!!

[Truman]

I feel, now it is time to RTFM

BicubicResize(NewFrameWidth,NewFrameHeight[,b,c],CropSourceLeft,
\ CropSourceTop,SourceFrameWidth,SourceFrameHeight)

BicubicResize(320,160,1/3,1/3,10,10,630,424)

is the same as

Crop(10,10,630,424)
BicubicResize(320,160,1/3,1/3)
