It's probably not an out of memory error either since VS only uses 1GB of ram as cache at most by default.

Cache is one thing, but there's also memory, allocated by filters. Intermediate buffers and such. When these buffers need to be large for large frames - you can easily run out of continuous memory chunks to allocate them.

Howdy folks,

I'm having some difficulty getting qtgmc to work with r32. Here is my script:

import vapoursynth as vs
import sys
sys.path.append("/usr/local/lib/python2.7/site-packages")
import mvsfunc
import adjust
import havsfunc as hf
import functools

core = vs.get_core()
core.std.LoadPlugin("/usr/local/lib/libffms2.so")
core.std.LoadPlugin("/usr/local/lib/libmvtools.so")
core.std.LoadPlugin("/usr/local/lib/libnnedi3.so")
core.std.LoadPlugin("/usr/local/lib/libfmtconv.so")
core.std.LoadPlugin("/usr/local/lib/libtemporalsoften.so")
#core.std.LoadPlugin("/usr/local/lib/vapoursynth/libremovegrain.so")

video = core.ffms2.Source('lossless.avi')

deint = hf.QTGMC(video, Preset='Medium', TFF=True)

deint.set_output()

and here is the error I'm receiving:

Any ideas why I can't find that module?

You're missing the SceneChange plugin.

[cwk]

Thank you for the reply vs_fan.

I have downloaded the package, and see c code, but no configure or make file for compiling on Linux.

Those of you using Linux, how did you compile this plugin? My early attempts with gcc are failing.

Try this:

gcc -fPIC -O2 -msse2 -std=c99 -shared -I/usr/lib/vapoursynth -o libscenechange.so scenechange.c

[cwk]

Thanks jackoneill. That got me going. I had to do the same for the temporalsoften.c file that came with chikuzen's scene change package.

I'm using 64bit version for fmtconv r20 from https://github.com/EleonoreMizo/fmtconv/releases
Is there a newer version to try?
-> redownloaded the version, rebooted system cleared python cache and now it works

---------------

Just wondering:
Is there a IVTC filter for Vapoursynth with works with all color spaces?
(IT and VIVTC seem to only work with YUV420P8 from what I could gather.)
I was hoping to get rid of all the ConvertTo...-calls which I sometimes have to add to my AvisynthScripts to be able to use all filters.

luma/chroma_threshold, scenechange are all floating point parameters now and they range from 0.0 to 255.0 still for compatibility reasons.

uhmm, and the useless parameter "mode" got its ass kicked

Nope, vivtc only does its decision in one colorspace. Use the clip2 argumebt to apply thr matches to the unconverted clip. It's slightly more awkward but there's just so little telecined material in higher bitdepths...

Hi all,

I'm wondering, is anyone actively developing a native Vapoursynth version of DGDecNV?

I somehow had a native version of DGDecNV (I think it was released by Donald Graft himself), but then I just upgraded to the GTX 1070. The older version of DGNV doesn't work at all with the Pascal cards, so I had to update my version to DGNV to the latest ones.

Now, the problem is that the older version of DGDecNV won't open an index file created by a newer version, and I can't import the AVS dll of DGDecNV because it's an Avisynth 2.5 plugin. So at this point it feels like I'm screwed. What are my options now?

[Selur]

Afaik. Donald Graft is the only one with the source code, so he is probably the only one with the means to implement a native Vapoursynth version of DGDecNV.
IIrc DG won't write a native version for Vapoursynth unless Vapoursynth changes, see: http://rationalqm.us/board/viewtopic.php?f=8&t=441
your options are probably:
a. hope the Vapoursynth developers change their code (Avisynth 2.5 filter support and/or handling the frame rate normalization)
b. hope that DG changes his code (dropping Avisynth 2.5 support or alternatively share a 2.5 and 2.6 filter and/or so the frame rate normalization)
c. you could try if it works to create an avisynth script where you use DGDecNV and then open that script as source using vsavsreader, but reading the end of http://forum.doom9.org/showthread.php?t=165957 that might also not work
d. forget DGDecNV in Vapoursynth for the time being
-> my guess is that if c. doesn't work you are stuck with d.

-----

Use the clip2 argumebt to apply thr matches to the unconverted clip.

thanks, totally overlooked that parameter

Same. The script does evaluate in VSEdit. But segfaults on preview.

[feisty2]

guess I messed "scenechange" up
investigating...

[kolak]

Could someone translate this into vs please:

changeFPS(60000, 1001)
assumeTFF()
separateFields()
selectEvery(4, 0, 3)
weave()

if it's actually possible. Thx!

import vapoursynth as vs
import havsfunc as haf
import mvsfunc as mvs

core = vs.get_core()

src = ...

last = src
last = haf.ChangeFPS(last, 60000, 1001)
last = mvs.AssumeTFF(last)  # Actually, not all filters support this, unfortunately
last = core.std.SeparateFields(last)
last = core.std.SelectEvery(last, 4, [0, 3])
last = haf.Weave(last, tff=True)  # this one doesn't
last.set_output()

This should do it. You need mvsfunc and havsfunc for this to work.

[kolak]

I assume this won't support 8bit+ bit depths?

just out of curiosity, no offense, you obviously should be a much better programmer than me cuz you wrote vsedit, and making a floating point version of temporalsoften should be easy like a blink to you, right?

If I knew how it was supposed to work - yes. If I would dedicate time to read and understand the original filter - sure, I could have rewritten it for float input. Or even simply upgrade the existing one. But I've got much on my plate. Not even working on vsedit as much as I'd like to.
