Resizers - What to use and how?
 
Dialhot have mentioned two resizers I haven't tried yet:
GausianResize and Lanczos4Resize. How do they work? Do I need to download anything to use them?

Another question:
If I want to double the size of my source video (DVD), do my filtering in that size and then downsize to 704*576/480. How will I do that?

Manual. Read the f...

They are internal to avisynth 2.5.6 as I said. And the manual is in the "Doc" directory.

:D I knew it! 8)
I've read the manual but regarding the GaussResize I can't figure out where to use the "p" parameter (default 30). I would like to change it closer to 100.

I was interested in GausianResize filter also after Phil recommended it to me.

I just wanted to know how stable is AviSynth 2.5.6 Beta4? I am currently using AviSynth 2.5.5 and am a bit dubious about upgrading to the betas as I have heard some problems with them.

Okay, I confess, there is a mismatch in the doc.
Look at the line for pointresize taht is just under :
Code:

GaussResize (clip, int target_width, int target_height, float "src_left", float "src_top", float "src_width", float "src_height")
PointResize (clip, int target_width, int target_height, float "src_left", float "src_top", float "src_width", float "src_height", float "p")

Pointresize does not have any "p" parameter... the to lines are simply switched ;)

Note: for any avisynth plugin or command, you can put the parameters in the order you want, simply by naming them all. You have to use the correct order only if you don't want to use the names.

Crop(704,480) is the same as Crop(width=704,height=480) and also Crop(height=480,width=704)
