Avisynth: Correct Apect Ratio Script ?

[khusru]

can someone please give me a script so that i can keep the correct aspect ratio when encoding, im farely new to the script stuff. also can someone give me a script to make an anamorphic widescreen picture, thanks for all help

[khusru]

also, i tried out my first script
AviSource("C:\once upon a time in mexico.avi"),
and it opened the video file okay, but the picture quality wasnt as good, is this NORMAL, if i open the video file by double clicking it it looks so much better

All scripts given in this section and that use "gricrop" handle correctly the A/R problem.

All you have to do is :
- if your source is anamorphic, add source_anamorphic=true in gripcrop line
- if your source isn't anamorphic, add source_anamorphic=false
- if you want to make a TARGET anamorphic add dest_anamorphic=true
- if you want to make a TARGET non-anamorphic add dest_anamorphic=false

Note that by default gripcrop use "source_ana=true" and "dest_ana=false".

All is matter of codecs, directshow filters and settings of all of them. But correctly configured, and with the correct codecs, the playback is the same.

Note: is you are doing avi, you should use the scripts given in avi->kvcd forum. And you MUST stop post in this one.

if i want my output to be anamorphic, is this the full script??


AviSource("C:\once upon a time in mexico.avi")
dest_anamorphic=true


also after using the script to run the video file is it normal for the quality to not be as good as normal

Nope, you have to use Gripfit!

AviSource("C:\once upon a time in mexico.avi")
Gripcrop(704,576, dest_anamorphic_true)
Gripsize("Bicubicresize")
Gripborders()


You see the needed lines, Dialhot just explained the right parameters!
Do look at the optimal scripts in here and you do understand

Im shure you didn't copy the mentioned lines correctly as the error means you did typ anamporphic! and its called anamorphic!

No, in fact he wrote "dest_anamorphic_true" where I said top put EGUALS true.

dest_anamorphic = true

[khusru]

dial hot this is how i typed it now

AviSource("C:\once upon a time in mexico.avi")
Gripcrop(704,576, dest_anamorphic=true)
Gripsize("Bicubicresize")
Gripborders()

and it shows another error message, CANNOT LOAD SYLIA SCRIPTING LANGUAGE ( thats in virtual dub) when i use media player it says THERE IS NO FUNCTION NAMED GRIPCROP,

help as i am lost

[khusru]

can i use scripts in tmpg and how do i use it?

[rds_correia]

Hi there,
Just download yourself a GripFit_YV12 plugin so that those messages coming out of media player and VDub stop annoying you.
You can use your script in tmpgenc but you'll neec ReadAVS.dll plugin.
Make sure you follow the installation notes for ReadAVS and just put GripFit_YV12 in your plugins directory
C ya

Note: search for those plugins at http://www.avisynth.org/warpenterprises/

You're posting in the 'Optimal Scripts' forum, but have you actually taken a look at the Latest Scripts thread

You'll see from that, that your script is far from complete.

Also, remove the spaces from your looooooooooong file name, it will save problems later

[khusru]

AviSource("C:\once upon a time in mexico.avi")
Gripcrop(704,576, source_anamorphic=true)
Gripsize("Bicubicresize")
Gripborders()
LegalClip()

unfilter(50,50)
GripCrop( X, Y )
GripSize(resizer="BicubicResize")
STMedianFilter(8, 32, 0, 0, 8, 32)
# SpaceDust() # Optional - for some "not so clean" DVDs.
temporalsmoother(1,2)
mergechroma(blur(1.50))
mergeluma(blur(0.2))
# Convolution3d or DCTFilter for extreme worse cases.
GripBorders()
LegalClip()

Is this okay for my final script, my source is anamorphic, but i want my destination
to be a 4:3 image with the corret borders

[Jellygoose]

If your source is anamorphic, you'll get egg-headed persons, when you want it to be 4:3.

btw: you're using the optimal script for AviSynth 2.0x, which is outdated. you should get AviSynth 2.5x and use the optimal script for that version.

EDIT: that script is totally screwed man. You should read a little bit about scripting on the AviSynth Homepage or in the Docs. Why do you have 2 GripCrop lines in it, and one without any values added?

Your source is an avi and as 99% of chance to NOT be anamorphic.
Only DV avi can be anamorphic. Divx aren't except if the guy that did it is dumb.
