Avisynth Filters Order Important?

Dialhot · #1 07-06-2004, 05:27 AM

Hi,

I don't find the thread where Jorel and I were discussing about that so I post a new one.

Discussion was about comparing this :

Code:

Mpeg2Source(...)
Deen()
Undot()

(that is the script I use for DVD->KDVD) and Jorel's suggestion :

Code:

Mpeg2Source(...)
Undot()
Deen()

We already agreed that visual difference in not noticiable. We also agreed that the encoding speed is the same.

But what Jorel didn't see (or kept for him

) during his tests is that :
My order : encoded sample size : 40.377 KB
Jorel' one: encoded sample size : 40.305 KB

Okay, that's not a lot, but a little gain is better than nothing

Thank you Jo'

was not a "secret" Phil, i did lots of screenshots from scenes with full details for comparisons without encode and i really don't knew that too... i was "lucky"!

i know its a mute point but is there any diff in chaining them ?
Undot().Deen()
Deen().Undot()

i did read it but that was one after the other from what i understood chaining the filters produced diffrent results but i might (READ: probally am

) wrong.

You are wrong

chaining or putting them on separate lines is the same.

thxs for that quick answer dialhot/jorel, thats what i like about this forum you post a question and you get a quick precise answer, unlike doom9 you post a question get 20 views on the post and no one answer except a member from here (jorel

).
