Eedi3

[x264]

Can someone explain me the syntax of EEDI3? how do i use this to remove aliasing?

[poisondeathray]

There are many other antialiasing functions you can use.

But you can use it like this for AA

e.g

src=whateversource()

w1=src.width
h1=src.height

src
turnleft()
eedi3()
turnright()
eedi3()
spline36resize(w1,h1)

which works better at removing jaggies found in anime, eedi3 or nnedi3?

[poisondeathray]

which works better at removing jaggies found in anime, eedi3 or nnedi3?

It depends on the source, and the type of jaggies . As usual, try a few filters out

[x264]

LoadPlugin("D:\Program Files (x86)\AviSynth 2.5\plugins\eedi3.dll")
MPEG2Source("D:\Users\x265\Desktop\VTS_01_1.d2v", cpu=0)
trim(363, 43365)
AnimeIVTC(mode=4, omode=2, pass=2, aa=0)
Crop(4, 2, -4, -0)
tweak(sat=1.04)
src=MPEG2Source("D:\Users\x265\Desktop\VTS_01_1.d2 v", cpu=0)
w1=src.width
h1=src.height
src()
turnleft()
eedi3()
turnright
eedi3()
spline36resize(w1,h1)

I am getting an error saying there is no function named "src"

h1=src.height
src()
turnleft()
eedi3()
turnright()
eedi3()
spline36resize(w1,h1)

I am getting an error saying there is no function named "src"

Try this

LoadPlugin("D:\Program Files (x86)\AviSynth 2.5\plugins\eedi3.dll")
MPEG2Source("D:\Users\x265\Desktop\VTS_01_1.d2v", cpu=0)
trim(363, 43365)
AnimeIVTC(mode=4, omode=2, pass=2, aa=0)
Crop(4, 2, -4, -0)
tweak(sat=1.04)
src=last


w1=src.width
h1=src.height
src
turnleft()
eedi3()
turnright()
eedi3()
spline36resize(w1,h1)

Note "src" doesn't have the "()" in the 2nd part , I underlined it

[x264]

I still get the same error

[poisondeathray]

did you see my edits above ? take out the brackets

After applying this filter a vertical green bar appears at the bottom of the frames and the frames look a lot
worse.

[x264]

Filtered



Original

"how do i use this to remove aliasing?"

And then you post an example where your source image is downright perfect. You shouldn't get the green bar if you change your Crop command to Crop(4, 0, -4, -0) or Crop(4, 2, -4, -2).

[x264]

Changing the crop value fixed the vertical bar but the edges look ugly

[Selur]

then use the anti aliasing filter of your choice: Sangnom, EEDI2, maa, daa, ediaa, aaa, ssa, splinaa, supaa, naa, shaarp, aaf, nnedi, nnedi2, antialiasing,...

@ Selur
Why is the above screenshot becoming worse after using EEDI3?

[Brad]

What part of the "original" screenshot that you posted looks aliased to you? It isn't. That's why the filtered image looks worse.

[x264]

Ok, what do the functions Turnleft( ) and Turnright( ) do?

[Selur]

I agree with vaporeon800, all these aa-filters are not intelligent in any way so applying a filter that is not needed can break things.

Ok, what do the functions Turnleft( ) and Turnright( ) do?

flip the image,... http://avisynth.org/mediawiki/TurnRight

[x264]

I read that but why are those functions called before the EEDI3? do they aid in fixing the aliasing?

[Selur]

to do a vertical and horizontal anti-aliasing

[x264]

Are there any differences between NNEDI3 and EEDI3?

[Selur]

yes

[x264]

Could you explain these differences?

[poisondeathray]

There is a saying in America: "If it ain't broke, don't fix it"

In avisynth , the eqivalent is "filteritis"

Often you cause more damage trying to "fix" something that doesn't need to be "fixed."

This is clearly not a case where you would apply AA

[x264]

Is this code correct?

src=last


w1=src.width
h1=src.height
src
turnleft()
NNEDI3()
turnright()
NNEDI3()
spline36resize(w1,h1)

[Selur]

it's basically the same as the typical aa via nnedi3:

turnleft().nnedi3(field=1,nsize=4,dh=true).turnright().bicubicresize(width,height,0,0,0.5,0)

so yes, the it's apossible way to do anti aliasing, but like mentioned multiple times:
your source doesn't need anti aliasing and like you saw using anti aliasing will break stuff,...

[poisondeathray]

Is this code correct?

src=last


w1=src.width
h1=src.height
src
turnleft()
NNEDI3()
turnright()
NNEDI3()
spline36resize(w1,h1)

Yes it is, for antialiasing. The screenshot you showed doesn't have any notable aliasing

All antialiasing functions will lower the effective resolution on a clean image = lower quality
