So what do people want me to support? For the first time ever it's now kinda possible for me to support both 3.5.x and 3.6.x but I'll have to compile twice as many modules and modify the installer a bit.

Opinions? Obviously only officially supporting the latest Python is generally the least amount of effort.

That's a better option because you'd have more time to add features to vs than compiling it

NEWS: Python is now supported in visual studio 2017
could code your modules or complex scripts with it if you want to

What's the easiest way to mount a vpy-script in R35 ?
How can I use Pismo (the one in the installer) for this ?

Run "avfs.exe scriptname.vpy". It can be found in the directory where VapourSynth was installed.

how to make a global plugin initializing list for all functions in your module:

class get_core:
      def __init__(self):
          self.core = vs.get_core()
          self.xxx  = self.core.xxx.xxx
          self.yyy  = self.core.yyy.yyy

def f1(src):
    core = get_core()
    clip = core.xxx(src)
    del core
    return clip

def f2(src):
    core = get_core()
    clip = core.yyy(src)
    clip = core.xxx(clip)
    del core
    return clip

so no "xxx = core.xxx.xxx" in both f1() and f2()

Here's a test build with python 3.6 support. There are no other notable changes. Should work, I guess.

would be nice if SubText would also support .srt subtitles (https://github.com/HomeOfVapourSynth...on/VSFilterMod seems to be Windows only),...

But then someone would have to write Yet Another SRT Parser...

[Mystery Keeper]

We need one cross-platform all-formats subtitles renderer. With webvtt support.

and ttxt ...

Hi...I installed Python 3.6.0 and it is working fine.

However when I try to install "VapourSynth-R35" it shows an error... "At least one version of the core library has to be installed"...

I am newbie to python... Pl. guide how to install core library.

Thanks

VapourSynth r35 explicitly requires Python 3.5. VapourSynth r36 test1 explicitly requires Python 3.6. It has a known regression though. Better wait till next update.

R36 test2

Changes:

r36:
added misc filters to included vapoursynth plugins
fixed several edge cases when specifying color values for blankclip and addborders, inf and nan are now always rejected and floating point values can be any finite value
vspipe will now properly report floating point formats in y4m instead of incorrectly making them look like integer, for example C420ps and C420ph will be used to mark single and half precision respectively
avfs will now reject scripts that don't have an avs or vpy extension to avoid pointless error mounts
fixed blankclip handling of color for compat formats
added sample type to vspipe info output
improved a few installer error messages when python can't be found
now uses python 3.6 in windows
fixed potential crash when two clips are added together (Kamekameha)

Does there exist a filter (64-bit) for tackling a weird telecine pattern?

I have some material which seems to have a pattern "pppccpppccpppccpppccpppccppppcc" where p is a non-combed frame and c is a combed frame. VIVTC cannot tackle this one because the pattern is not constant enough.

[LigH]

At least it seems to be regular... usually it's advisable to count the number of equivalent fields to name the pattern, and to look at them as a Bob() result to identify blends. And I would suspect blends for your case, it sounds like blended PAL speed-up rather than Telecine.

Maybe you can provide a short prominent sample?

[Boulder]

I didn't check very thoroughly, at first I thought the material just needed a regular IVTC and then noticed the odd jumps when there's the 4:2 pattern. DGIndexNV shows NTSC and no percentage for FILM so it's hard telecined. It would probably look really ugly when played back on a DVD player..

I'll get you a sample later today when I get back from work.

[Mystery Keeper]

VDecimate is lacking the N in M decimation. Only 1 in M. That is what needs to be improved.

[Boulder]

Here's a testclip.

I probably need to do the TFM and TDecimate magic in Avisynth, save to a lossless AVI and do the rest in Vapoursynth with that clip. Tough job, but possible to automate.
