Gripfit questions
 
Hi can someone tell me where to look in the manual about the parameters for gripfit,because i can't find it

or
just explain this


GripCrop(528, 480, overscan=2, dest_anamorphic=true)

I.m not sure what the parameters mean after the overscan part

Also in moviestacker which resize is the best to use ,i always have used bicubic standard but was just reading some older threads and it says to use biubic precise

What are the benefits of using gripfit over avisynth for resizing

Thanx

The doc are here :
http://www.kvcd.net/forum/viewtopic.php?t=2292

The dest_anamorphic paramater is to make anamorphic target. That means somethign that must be seen on 16:9 TV set in order to have a correct A/R. This is usefull for (K)DVD only.

All depend on the rest of the script. The filters that are before and after the resize take in account the result of the resizing.
Bicubic precise gives picture more sharpen than bicubic standard. So if you have a script that already sharpens the picture (with asharp for instance), usign bicubic precise can lead to an over sharpened picture.

None ! If you are confident enought with moviestackern stop using gripfit and use directly the avisynth command. You will avoid a lot of problems.

Thanx Phil

I didn't know that Grigfit was with Sansgrips filters thats why i never looked there :oops:

So since i'm using the MA script i am better to stick with bucibuc standard

Hum, I see there the limits of my english :-);
When I say "confident into" that didn't mean "trust into" moviestacker. I wanted to say "if you know how to use moviestacker then stop using gripfit and use the parameters of moviestacker directly".

hi,

If you want to use bicubic precise, you can use 2 gripfit internal variable: GripFit_resize_width y GripFit_resize_height, and replace the gripsize line directly with bicubicresize, this way:

BicubicResize(GripFit_resize_width, GripFit_resize_height, 0, 0.6)

Salu2
