Possible to make an Avisynth 2.5 filter with source of a 2.0 filter?

[MatLz]

Is possible to make a compatible Avisynth 2.5 filter with a source of a filter designed for Avisynth 2.0?
It's the simple "blendfields" included in old mpeg2dec.

Doesn't mpeg2dec work under avisynth 2.5.x?

Maybe but not for me... Lot of artifacts and green display.

[kemuri-_9]

you do have

SetPlanarLegacyAlignment(true)


in the script right after you use mpeg2dec right?

[MatLz]

With or without, it's same result. Green display and inverse delay in colors. I can't better explain with my poor english sorry.

[kemuri-_9]

you did generate the .d2v that you passed to mpeg2dec with dvd2avi as well right?

i used mpeg2dec up until some time ago with avs 2.57 until i switched over to neuron2's dgindex/dgdecode combo so i know it works up until that point.

[MatLz]

I use new dgindex to index my mpeg files. But I had try dvd2avi one time for indexing with hope for compatibility with that filter, but...no result.
I have try to load the 2.0 with loadpluginex...but nothing work. Really...

What exactly are you trying to achieve with that filter that you cannot achieve in more modern ways?

Blend fields properly.
I've read this filter is the blend mode of the internal vdub deinterlace filter ported to Avisynth. This is the only blender which satisfies me. But now I use Avisynth, not vdub.

Here you go. I extracted it to its own DLL and ported it to 2.57 for you.

neuron2, can you implement YV12 support in this? On YV12 input, it reports "Requires RGB or YV12 input!" (lol). YUY2 and RGB32 are working. Also, kind of strange how there was no native dumb blend deinterlacer for AVS 2.5.

How about Bob().Merge(SelectEven(), SelectOdd())?

Woaa...you did it?
So, the answer to my question is YES. It's possible to make new with old.
Thanks Neuron2.

How is blendfields from mpeg2dec different than blur(0,1)? I thought they were the same [1 2 1] vertical kernel.

[MatLz]

How about Bob().Merge(SelectEven(), SelectOdd())?

It seems that doesn't work.
But this works:

Merge(selecteven(bob(mpeg2source(".d2v"))),selectodd(bob(mpeg2source(".d2v"))))

Seems to be an alternative to Blendfields! ;)

[Gavino]

Merge(selecteven(bob(mpeg2source(".d2v"))),selectodd(bob(mpeg2source(".d2v"))))
Isn't that the same as:
mpeg2source(".d2v")
Bob().Merge(SelectEven(), SelectOdd())

Obviously, I was assuming an appropriate source filter to be used first.

[MatLz]

It is not the same thing. "Bob()." must be placed before selecteven/odd.

[Gavino]

Ah yes, I should have said

Bob()
Merge(SelectEven(), SelectOdd())

A subtle example of when '.' is not the same as a new line.

[tritical]

blur(0,1) and blendfields() are the same except for rounding and handling of the very bottom line :)
