avs script help

[natty]

can someone here give me an example of a .avs script which is movie size 720 x 576 with no borders please

What does it need to do ?

A very simple script might be

DirectShowSource("pathtofile")
Lanczos4Resize(720,576)

However if you are resizing to maintain an aspect ratio that isn't 4:3 non-square pixels then this will give you a distorted output. If you want to crop and zoom a widescreen source, this will give you a distorted output.

The exact nature of the script is driven by the need that it is serving. So what do you need to do ?

it will be 4.3 and I dont want any borders but cannot remember how to do script for no borders

[guns1inger]

Don't use the AddBorders function. Borders aren't added by the resize. If you resize to full frame, and don't use AddBorders, you get image to the edges.

ok so my script needs to be

avisource("AVI file name",audio=false)
LanczosResize(720, 576)

i use batchccews to do this so say for instance I have a movie which says 624 x 336
I have this formular here so when I worked out the above movie sizes I ended up with roughly 551 is this what you make it also so how do I do a script for that

OK, this is a bigger issue. Your source is not 4:3, it is 1.85:1. Therefore you either have bars top and bottom, or crop the ends off.

If you are happy to have it widescreen then use FitCD. It is the simplest and most reliable solution.

For 4:3 letterboxed, FitCD gives

DirectShowSource("pathtofile")
Lanczos4Resize(720,432,5,0,613,336)
AddBorders(0,72,0,72)

and for 16:9 anamorphic

DirectShowSource("pathtovideo")
Lanczos4Resize(720,576,5,0,613,336)

(Note : no bars in a widescreen TV, but there will be in a 4:3 TV. Must be encoded as 16:9)

If you want to fill the screen then you have to crop the ends off the image, then resize.

have u checked my edited formular and also how did you get 1.85:1. I dont understand this much

woow this fitcd is a great program is there any help on learning all this fitcd thing

also in read me of fitcd I dont understand this bit

0. Copy all necessary avisynth-plugins in the plugin-directory.
FitCD will automatically create a directory in the install-directory
of avisynth.
For proper decoding of old and new D2V-projects, copy the MPEG2Dec3dg.dll
and DGDecode.dll in the plugin-directory.

Your formula is flawed insofar as it assumes the same pixel aspect ratio for source and target. Generally, avi files encoded with Divx/Xvid etc have a 1:1 PAR, whereas DV and Mpeg from DVD or digital broadcast have non-square pixels. Pixel aspect ratio must be taken into account when doing the calculations - which is why FitCD is so great.

FulciLives wrote a great guide to FitCD is you search for it.

I haven't read the readme, to be honest. I just installed avisynth and away I went.

Yeah, for AVI sources, you don't need the DGDecode.dll stuff anyway. Here's the FulciLives Guide to FitCD:
