Vapoursynth

[aldix]

think i've almost everything fixed and set up now the way i need to. sorry about being so dense.

i'm still struggling with core.std.Interleave tho. what's the correct way using it?

i'm getting

vapoursynth.Error: Interleave: the clips' formats don't match

using:

...
src = core.fmtc.resample(clip,w=1280,h=720, kernel="blackmanminlobe", taps=4)
...
video = core.f3kdb.Deband(video,sample_mode=2,dynamic_grain=False,keep_tv_range=False,dither_algo=3,output_depth=8,y=48,cb=48,cr=48,grainy=48,grainc=48)
int = core.std.Interleave(clips=[src,video])
int.set_output()

and both are 1280/720.

[_Al_]

resolution is not enough, comment out that interleave line and add:
src = src.text.ClipInfo()
src.set_output()
to see parameters of that clip and then delete those two lines and add other clip:
video = video.text.ClipInfo()
video.set_output()

| Format: YUV420P16
...
Format: YUV420P8

hmm, so src clip is 16-bit and filtered is 8? but how do i change the src clip to 8-bit right at the beginning?
and will it mess all the rest up again, or what?

[_Al_]

don't know , you can change it right after loading src source or just before interleaving

src = core.resize.Bicubic(src, format = vs.YUV420P8)

[aldix]

think i fixed it with these changes.

src = core.fmtc.resample(clip,w=1280,h=720, kernel="blackmanminlobe", taps=4,css=420)
src = core.fmtc.bitdepth(clip,bits=8,dmode=1)

at least the script runs now. but, um, when i initiate the preview, i've no idea which frames from which i'm looking at?

too used to moving back and forth with keyboard arrows with the regular interleave. what's the how-to here?

[aldix]

hmm, never mind.

think it does work the same way, though. just the changes are too negligible with finesharp. oh well.

gotta try to get seesaw to work now

[_Al_]

You could switch to zimg - Vapoursynth's resize, like in my example, that changes resolutions, color spaces and much more. fmtconv is another way to do it though. Zimg is written by myrsloik I think so I'm sure it sits well within Vapoursynth.

[edcrfv94]

Will vivtc.VFM support ovr text file like tivtc?

[_Al_]

If anyone can answer,
why there is kernel or resize method set as resize attribute and not just an argument in core.resize ?
example: clip = core.resize(clip, kernel = Bicubic, ......)

[DJATOM]

Something like that will work:

resizer = {
    'bicubic': core.resize.Bicubic,
    'bilinear': core.resize.Bilinear,
    'spline36': core.resize.Spline36,
    'spline16': core.resize.Spline16
}
clip = resizer['bicubic'](clip, 960, 540, format=vs.YUV420P8)

[_Al_]

I meant why is that, if author wanted that to look more like Avisynth command, to keep a pattern. Not that it matters.

That example is cool, yes tables with dictionaries, tuples, lists, that's the way to go. :-).

Or checking if kernel exists might be done by checking if it exists as a resize attribute:

my_cool_function(clip, kernel='Bicubic', miracle_settings=True)
try:
     getattr(vs.core.resize, kernel)
except:
      print("Wrong kernel")

edit: fixed missing quotes , because that's the whole point in this example with getattr , getting an object from a string name

[aldix]

ok, i'm back again so please bear with me here.

...
maskstars=src.mt_binarize(upper=false)
...
mt_merge(last,maskstars)
...

so i went ahead and tried

...
maskstars = core.std.Binarize(src,threshold=0)
...
video = core.std.Merge(video,maskstars)
...

but think i'm doing something wrong, cos "threshold=0" doesn't seem to equal "upper=false" for video picture changes color in weird ways etc. so how should i use the vs binarize? is it even what i'm after here?
merge seems to be mt_merge, though, so at least that is straightforward.

z = 2 # z = zero point
p = 0.9 # p = power
str = 0.9 # str = strength
rad = 1.0 # radius for "gauss"

o = last
g = o.bicubicresize(round(o.width()/rad/4)*4,round(o.height()/rad/4)*4).bicubicresize(o.width(),o.height(),1,0)

mt_lutxy(o,g,"x x y - abs "+string(z)+" / 1 "+string(p)+" / ^ "+string(z)+" * "+string(str)+" * x y - x y - abs 0.001 + / * +",U=2,V=2)

still don't know what to do with ^. as much as i googled, there seems to be some alternative for mt_lutxy under vs, but not like i'd know how to use it.
the resize can be done with core.std.resize etc i suppose. as far as the following calculation goes though, i've no idea. as much as i can recall, this
script snippet is something Didee wrote ages ago (if that helps any).

thanks!

maskstars=src.mt_binarize(upper=false)

in AVS is equivalent to

maskstars=src.std.Binarize(threshold=128+1, planes=[0])

in Vapoursynth.

The equivalent in std.Expr() is "pow".

It could be implemented through std.Lut2() or std.Expr(). The semantics of the later one is more close to mt_lutxy(), e.g.

core.std.Expr([o, g], [f"x x y - abs {z} / 1 {p} / pow {z} * {strength} * x y - x y - abs 0.001 + / * +", ""])

Avisynth functions and their VapourSynth equivalents may be helpful to you.

awesome! thank you so much, i've the maskstars part sorted now.

how would i write this in vs though? with a bunch of different core.resize.Bicubic calls or what? hmm, and what's the equivalent in vs for "round" and "rad"?

g = o.bicubicresize(round(o.width()/rad/4)*4,round(o.height()/rad/4)*4).bicubicresize(o.width(),o.height(),1,0)

thanks a lot in any case. really loving the community here!

g = o.bicubicresize(round(o.width()/rad/4)*4,round(o.height()/rad/4)*4).bicubicresize(o.width(),o.height(),1,0)

g = o.resize.Bicubic(round(o.width/rad/4)*4, round(o.height/rad/4)*4).resize.Bicubic(o.width, o.height, filter_param_a=1, filter_param_b=0)

"rad" is a variable in your code,

rad = 1.0 # radius for "gauss"

(Actually "round" should be implemented like this)

_round = lambda x: -int(-x+0.5) if x < 0 else int(x+0.5)
g = o.resize.Bicubic(_round(o.width/rad/4)*4, _round(o.height/rad/4)*4).resize.Bicubic(o.width, o.height, filter_param_a=1, filter_param_b=0)

thank you so very much!! yes! this works.

and now i've whole of my old avs script working!

Could anyone please advise on how to link ffms2 plugin to VapourSynth on Ubuntu linux? As there is no VapourSynth FATPACK for linux i had to compile/build ffms2. Please see below and advise, thanks!

Maybe someone could make a flatpack / appimage / snap version with vsedit, vapoursynth and some plugins.

[bjoker]

I solved issue of loading plugins by

root@ubuntu19:~# cat MyMovie.vpy
import os
import sys
ScriptPath = '/root/VS/Scripts'
#LoadPlugin(path='/usr/local/lib/pkgconfig/ffms2.pc')
sys.path.append(os.path.abspath(ScriptPath))
import vapoursynth as vs
core = vs.get_core()
core.std.LoadPlugin(path='/usr/local/lib/vapoursynth/libffms2.so')
clip = core.ffms2.Source(r"/root/eega-1min.mkv", cachefile = r"/root/eega-1min.mkv.ffindex")
clip.set_output()

root@ubuntu19:~#

But do I need to load each one manually that I need?

[Are_]

The problem is /usr/local/lib is not in your path.
You can pass it to configure when you build ffms2 and then install to the common path:

./configure --prefix=/usr --libdir=/usr/lib64

Ops, and then soft-link in "/usr/lib64/vapoursynth" I guess.
