I guess the problem comes from the fact that mt_merge needs to perform a resizing operation when luma=true, but Avisynth does not support resizing of "planar hacked" YUY2 input ... ?

However: yup, most probably you don't need luma=true. It seems that you're currently dealing with masks provided by MVMask(). Those masks contain the needed information on all three planes, so using the normal U=3,V=3 in mt_merge should do what you want.
If that's not the case, you have to construct your mask clip manually by means of YtoUV() operations.

Didée!
Code:
mask=Planar2Interleaved(maskpl)
HorizontalReduceBy2(mask).YtoUV() 
mask=Merge(mask)
maskpl=Interleaved2Planar(mask)
maskpl mask in planar colorspace
mask YUY2 in interleaved colorspace.
This will be work?
yup.

Please advice:
Code:
mmask=Planar2Interleaved(mmaskpl)
YtoUV(HorizontalReduceBy2(mmask),HorizontalReduceBy2(mmask))
mmask=MergeLuma(mmask)
mmaskpl=Interleaved2Planar(mmask)
And use U=3,V=3 at mt_merge. This work like luma=true for YUY2 planar?
Now right?
yup.

Seems to be correct, yes.
Small nitpick: it does a little more work than necessary.
More efficient:
Code:
mmask   = mmaskpl.Planar2Interleaved()
mmask2  = mmask.HorizontalReduceBy2()
mmaskpl = YtoUV(mmask2,mmask2,mmask).Interleaved2Planar()

Hi Manao,

Is it normal that mt_edge doesn't output the same thing when using a named kernel and its equivalent kernel as defined in the html help file ? (like for instance "laplace" and "1 1 1 1 -8 1 1 1 1")

laplace is equivalent to "1 1 1 1 -8 1 1 1 1 8", while "1 1 1 1 -8 1 1 1 1" gets interpreted as "1 1 1 1 -8 1 1 1 1 16". The same applies to sobel ("0 -1 0 -1 0 1 0 1 0 2" and robert ("0 0 0 0 2 -1 0 -1 0 2").

Hi!

I have a little problem with the pi value... Maybe a bug!

In the documentation:
Quote:
V) Reverse polish notation.
[...]
The constant "pi" can be used.
But if I try a simple expression:
Code:
mt_lut("pi 2 / sin 255 *")
It return a black screen instead of a blank screen...

It would be great to fix this

REQUEST: mt_InFix

Any possibility that the MaskTools v2 developers could add a filter that translates reverse polish expressions to InFix notation - call it mt_Infix, if you will, or maybe make it an option in the mt_polish filter.

This would greatly assist non-programmers, such as myself, in deciphering and modifying the calculations/operations involved in scripted functions developed by others.

Thanks.

Wow, that was fast. Really excellent. Thanks alot.

Although self explanatory, I guess the documentation needs to be updated to include mt_InFix in the filter list.

Thanks again.

ah thanks i thought that was the case so i used 25 but i wanted to make sure because i saw a lot of these scripts for denoising and what not and most state 26 is needed so i hoped there was nothing in 26 they truly needed that 25 didn't have.

better safe than sorry so i asked lol


thx!

It would be nice if this was made clearer in the documentation, as I see a lot of scripts posted that erroneously use mt_masktools26.dll with Avisynth 2.5.

In practice, what problems can arise from using the wrong version?

I have no idea. Somebody asked me once to release a 2.6 version, so I did. But I didn't test it, and neither did I test cross compatibilities. I'll try to add a note (which nobody will read...) and find a more explicit naming scheme for the next release.
