FrameRateConverter (Official)

[Dogway]

Format() is AVS+ only I think, don't know from what version.

This is an HBD aware TV<->PC levels conversion function. link

And here is an HBD aware Levels function. link

They both require ExTools found in the repo.
I'm in the middle of a rebase so I'm taking my time and preparing an elaborated post for possible solutions, so if something triggers an error let me know, or use an earlier version of ExTools (v1.6 or v1.7).

EDIT: Oh by the way, this all to linearize an image/source right? I'm also in the middle of a refactor for Transforms Pack but the gamma function is very functional at this state. Pick the alpha and gamma value from this list.

I got gamma correction working with Levels. That's probably the best option.

[Dogway]

Good luck!

Releasing FrameRateConvert v2.0-Beta, DLL only. Works in both VapourSynth and Avisynth.

- Ported to VapourSynth
- Fixed a bug in StripeMask
- StripeMask linear gamma correction is now more accurate
- StripeMask now accounts for PC vs TV range
- StripeMask: added fullRange parameter, set to True if input is in full range

For VapourSynth, FMTC dll is required. For Avisynth, you can use the previous AVSI file and the StripeMask will have a few corrections. Note that StripeMask thr parameter default is now 28 instead of 26, and possibly could use further adjustment.

Thanks

Thx for the port.
I see some warnings / problems in vsedit

clip = core.frc.StripeMask(clip)

and if I want to preview the mask I get

Error on frame 0 request:
Resize error -1: invalid graph state L910: !m_state.has_chroma() || m_state.plan

core.frc.ContinuousMask(clip, 24000, 1000) #crashes the editor

Log shows this msg
setVideoInfo: The frame rate specified by ContinuousMask must be a reduced fraction. (Instead, it is 24000/1000.)

[MysteryX]

Fixed most of those bugs.

Error on frame 0 request:
Resize error -1: invalid graph state L910: !m_state.has_chroma() || m_state.plan

This error is in FMTC.transfer; but it works when run in VirtualDub.

video = core.resize.Point(video, format=vs.GRAY16)
video = core.fmtc.transfer(video, transs="709", transd="linear")
video = core.resize.Point(video, format=vs.GRAY8)

There's the option of converting to RGBS but it would be slower and would produce a slightly brighter output than in Avisynth.

I released a new beta at the same link.

[ChaosKing]

Is 16bit int or 32bit float input supported? Output of ContinuousMask() looks strange with non 8bit input.


The parameter seems to be ConvertFpsLimit(clip, num, den, ratio) but I get this error msg when calling ConvertFpsLimit(clip, 24000, 1000, 1)

vapoursynth.Error: ConvertFpsLimit: Can only set one of the following parameters: num/den (fraction), fps (float), preset (string) or match (clip).

+ it crashes with just ConvertFpsLimit(clip)

[MysteryX]

ContinuousMask gives strange output on regular clips. It's meant to process masks. I didn't document it either -- don't remember what it did exactly :P Works in the context it's used for though. Gives same output as it did before in Avisynth.

Since I can't register ConvertFpsLimit several times like in Avisynth, the syntax is now

"clip:clip;"
"num:int:opt;"
"den:int:opt;"
"fps:float:opt;"
"preset:data:opt;"
"match:clip:opt;"
"ratio:int:opt;"

Forgot to validate if none is set; fixed it.

I'm pretty sure this output is stranger then it should be

I'll answer like Microsoft. It's by design.

Just finished porting the first function. Only problem: GaussResize doesn't exist in VapourSynth. Also is BoxBlur equivalent to Avisynth Blur?

I could use some help here

import vapoursynth as vs
core = vs.get_core()

def frc_GaussianBlur42(input, var = None, rad = None, vvar = None, vrad = None, p = None):
{
    if not isinstance(input, vs.VideoNode):
        raise vs.Error('frc_GaussianBlur42: input is not a clip')

    var = max(0.0, float(var or 1.0)))
    rad = max(1.0, float(rad or pow(var, 0.5)))
    var = pow(min(max(0.0, rad), 60.0), 1.9) ## arbitrary max radius = 60

    vvar = max(0.0, float(vvar or var)))
    vrad = max(1.0, float(vrad or pow(vvar, 0.5)))
    vvar = pow(min(max(0.0, vrad), 60.0), 1.9)
    p    = p or 19

    w0 = input.width
    h0 = input.height
    w1 = round(w0/rad)
    h1 = round(h0/vrad) 

    B = input.resize.Bilinear( \
            min(max(4, w1 + (w1 % 2)), w0), \
            min(max(4, h1 + (h1 % 2)), h0))

    B = B.std.BoxBlur(hpasses=2, vpasses=2)
    
    if var < 0.01 and vvar < 0.01:
        return input
    elif B.Width > 8 and B.Height > 8):
        return B.std.GaussResize(w0, h0, p=p) ### NOT IN VAPOURSYNTH
    else:
        return B.std.Bilinear(w0, h0)
}

Note: just realized that ConvertFpsLimit can be quite useful in VapourSynth since ConvertFps doesn't exist! Good thing it's already ported.

fmtconv have GaussResize
https://github.com/AkarinVS/fmtconv/...onv.html#L1080

[MysteryX]

Thanks. Another issue. I had already ported ConvertFps, but ChangeFps (no blending) doesn't exist in VapourSynth either. What's the best solution? It's actually used several times for masks.

Also to consider: what to do in case of variable framerate input?

Finally... MaskTools2 hasn't been ported to VapourSynth??

[kedautinh12]

I think you need convert masktool2 from avisynth to internal functions of Vapoursynth. Here for example convert:

I need:
mt_inpand
mt_lut
mt_lutxy
mt_expand
mt_binarize
mt_circle
mt_merge

Pretty much the whole suite

Umm I guess ... You posted a link to another thread which has a script with all kinds of things that are mostly not relevant to the question that MysteryX asked ... but hey, it's nice to see you actually writing something instead of 'thanks' on every post
