Don't worry my friend, I'm working now, but I'll post those pic's this night.
BTW, I got an access violation error with gripborders. Do you know how I can solve it? (if you don't want post it in this thread send me a PM)

Jorel,

There is no need of posting anything : you will ALWAYS loose some pixels. That is a rounding matter !

Open Moviestacker; uncheck the "use gipfit box", open you source, set the corrrect parameters for your destination and see in the "Crop" are how much you are cropping !

No you want to see what happen if you do not crop ? In front of the Crop zone, set "No cropping" insteed of "accurate". And see HOW MUCH percent you screw up the A/R :!:

Thats is why you should STOP to use gripcrop. It's far better to use Moviestacker and play on the overscan/overlap and rounding border cursor to find the better compromise "A/R error <-> cropping".

That is what I do anytime.

Lets go further:
Watch the new FitCD as it now comes with better resizing routines and a much more sexier layout :D

Phil, pay attention as by your last sentence many noobs will do think about the usage of GripCrop in case of your Optimal scripts where you do use it. As they wont understand the sense of your post above like I or others do :wink:

I have used moviestacker, and now
:idea: I have understood that cropping to 704x576 and using overlap the error of aspect the ratio is 0,00% :D :D :D :D :D :D :D :D :D

byby.

@jorel
if you have need of help, there are I, :wink:
hello

Re: reply
 

Now you can understand better the line I said some post ago and that Prodater remembered this afternoon :

please zagor do this for me and post the pictures (if possible):

this scripts are from MovieStacker like recomendations.
:arrow: open the paint 2 times

Mpeg2Source("D:\xx\x.d2v")
BicubicResize(704, 352, 0, 0.6, 0, 0, 720, 480)
AddBorders(8, 64, 8, 64)

open in vdub (mod) and copy frame to clipboard and paste in paint.(1)

then,load the same frame with :

Mpeg2Source("D:\xx\x.d2v")
GripCrop(720, 480, overscan=1,source_anamorphic=true,dest_anamorphic= false)
GripSize(resizer="BicubicResize")
GripBorders()

copy frame to clipboard and paste in paint. (2)

:arrow: what do you see comparing the pictures :?:
:wink:

after your test i will post what i see,ok?
:wink:

reply
 

yes, i can. :D

I still don't know what is your point here but I wanted to say that we know Moviestacker has a bug (or a weakness) into the way he computes the resinzing parameter. We also know that FitCD is better on this point.

:arrow: but we really don't know how Gripcrop does it's own computing !
Perhaps it has the same bug than Moviestacker. Perhaps it's worst !

All this post simply because you don't want to drop griopcrop ?

no Phil, i think that i see EXACTLY what you wrote!
....maybe a bug in Moviestacker or gripfilter?!?!?

:wink:

<edited>
....or gripfilter!

So while zagor is comparing your two scripts, do the same with the last FitCD release as suggested by Inc and give us your opinion about it please.

i did Phil!
:wink:

zagor, please
do another script using: (from fitcd 121-overscan=1)

Mpeg2Source("D:\xx\x.d2v")
BicubicResize(704,352,0,0.6,0,0,720,480)
AddBorders(8,64,8,64)

do the same like using the other scripts, paste in paint(3)...compare!

(are the same parameters like in the script from moviestacker!)
:wink:

Phil, inc, zagor, Prodater64, Jell, ...my results and what i see:

using the script form Moviestacker or fitcd with bilinear/Bicubic/Lanczos are equal....
of course, no surprise!

using gripresize,
the image is concave,
the scene is "out of the center" in the picture (the image down and go to the left)
and loose parts of the scene within the (black)board!
i was clear? (my poor english explain something?) :oops:

then using the script: .....that seems with correct aspect radio....
(left alone gripresize )

Mpeg2Source("D:\LK3\lk3.d2v")
BicubicResize(704,352,0,0,720,480)
AddBorders(8,64,8,64)

i ask:
:arrow: HOW and WHY use letterbox and/or crop :?:

THIS is my doubt Phil :!:
:? :? :? :?
:wink:

You are so clear than you already describe this MONTHS ago and that is what make me decide to drop Gripcrop :!:

Do you understand now why I'm wondering why you still use it ? What happens to you during your time away from KVCD ? Alien abduction ? :-)

Jorel : can I knwo what were ALL your settings in moviestacker because I can't obtain the same results in any way.

Can you also tell us what was the error % of "Aspect Ratio" ? For sure it was quite big.

Phil,

see that my last encode here:
http://www.kvcd.net/forum/viewtopic.php?t=9927&start=0
i don't use gripresize no more!


see that script from moviestacker and fitcd:
BicubicResize(704, 352, 0, 0.6, 0, 0, 720, 480)
AddBorders(8, 64, 8, 64)

and with this script that give me the problems posted:
GripCrop(720, 480, overscan=1,source_anamorphic=true,dest_anamorphic= false)
GripSize(resizer="BicubicResize")
GripBorders()

:arrow: using overscan=1 like posted in all scripts in this thread the error=0% :!: :!:

then, my doubt remains:
:arrow: HOW and WHY use letterbox and/or crop :?:
:?

<edited>

Alien abduction ?
no, i'm alien! (from krypton)
:lol:

Excuse me , GUYS !!!
Can u see any visually noticable distortion in image when u get error 1%,2% or even 3.5% in moviestacker ??? :wink: :wink: :wink:
If so 8O 8O 8O
bman

I think till 2.5% it is not really noticeable...

bman,
like i posted before:
"using gripresize,
the image is concave,
the scene is "out of the center" in the picture (the image down and go to the left)
and loose parts of the scene within the (black)board! "

visually noticable distortion in image (with or without overscan 1,2,3)
it's not from Moviestacker or fitcd bman...
:arrow: it's from "gripresize" !

with that script from moviestacker and fitcd: (seems correct AR)
BicubicResize(704, 352, 0, 0.6, 0, 0, 720, 480)
AddBorders(8, 64, 8, 64)

HOW and WHY use letterbox and/or crop ?
my doubt remains!
:?

As said above, Moviestacker NEVER gives me the parameters that you have. So I can't verify that your error is 0% and try to understand why and how you can have this as I don't.

So please, give me ALL THE PARAMETERS that you set into Moviestaker : size of the source, size of the dest, A/R of the source, A/R of the dest, all borders of rounding (2,4,...16 ? or even 32?), crop to "accurate" or "no crop" or something else ?
All boxes checked also (anamorphic, PAL, IBU...)

ANYTHING please !

I'm sorry but I have big doubt that you can have a %0 !

Do a screenshot if you can !

Phil,
are you "lazy" to read today?!?!?
:lol: :lol: (kiddin)

i posted:
"see that script from
:arrow: moviestacker and fitcd: (just the same)
BicubicResize(704, 352, 0, 0.6, 0, 0, 720, 480)
AddBorders(8, 64, 8, 64)
and
and with this script that give me the problems posted:
GripCrop(720, 480, overscan=1,source_anamorphic=true,dest_anamorphic= false)
GripSize(resizer="BicubicResize")
GripBorders()

using overscan=1 like posted in all scripts in this thread the error=0% "

more:
crop accurate was used but
crop max height or accurate give the same values like posted!
source anamorphic!...(details in gripresize)

Phil wrote:
"I'm sorry but I have big doubt that you can have a %0 ! "
again i confirm:
:arrow: overscan=1 like posted in all scripts in this thread the error=0%

:wink:
that's all in the scripts (and the source, of course)

i don't know how to post the picture here
(but i can send by mail..include screenshot from fitcd and moviestacker)

:oops:

If DLing Moviestacker at office, installing it, opening it, trying to put the few info you gave into it, playing with ALL settings during 10 minutes and NEVER obtaining what you have (addborders(8,64,8,64) or even a 0% error)) is beeing lazy, so I am :wink:

EDIT: I just find which settings you have checked (actually, Moviestacker probably did it automatically when you loaded your source) : IUT-R BT !!!

Do you understand now why I wanted ALL the settings !

In your case that's right error is 0%. So now, the answer to yoru question :

"why letterbox insteed of cropping" ?
Because :
1/ I already said that "I rather to loose 1% of picture than to see 100% of it screwed up by the interpolation used in the resizer

and

2/ I do ANAMORPHIC DVD. And you can try to verify : no way to obtain a 0% error in this case.

FYI: I did a lot of DVD that have a 4 pixel border on right and left side. I don't know why but actually, it's better to crop it.
