Selur's Little Message Board

Hi,
Is it possible to run an encoding with both Vapoursynth scripts and Avisynth scripts ?

By the way, I actually only need to use one Avisynth custom script (which doesn't work in custom Vapoursynth script)

Thank you

afaik: No.
You can use Avisynth filters in Vapoursynth, but to use an Avisynth script it would need to be rewritten to Vapousynth.
What are you trying to do?

Cu Selur

OK... I'll get straight to the point then. I want to replace problematic frames (with black hole / circle, like perforation) with their duplicate counterpart.

Here is the script :

Code:
# Charge le plugin FFMS2

LoadPlugin("C:\Program Files (x86)\AviSynth+\plugins64+\ffms2.dll")

# Source vidéo

video = FFVideoSource("C:\Users\Admin\Desktop\FILM 3 - ETAPE 3 - DAVINCI.mkv")

# Fonction pour remplacer des frames spécifiques

function ReplaceFrames(clip source, int start1, int end1, int start2, int end2) {

    # Extraire les segments à garder

    segment1 = source.Trim(0, start1 - 1)

    segment2 = source.Trim(start2, end2)

    segment3 = source.Trim(end1 + 1, source.FrameCount - 1)

    # Assembler les segments

    return segment1 ++ segment2 ++ segment3

}

# Remplacement des frames 43125 à 43129 par 43120 à 43124

video = ReplaceFrames(video, 43125, 43129, 43120, 43124)

# Remplacement des frames 43301 à 43304 par 43275 à 43278

video = ReplaceFrames(video, 43301, 43304, 43275, 43278)

# Remplacement de la frame 22261 par 22257

video = ReplaceFrames(video, 22261, 22261, 22257, 22257)

# Remplacement de la frame 22262 par 22257

video = ReplaceFrames(video, 22262, 22262, 22257, 22257)

# Remplacement de la frame 22263 par 22256

video = ReplaceFrames(video, 22263, 22263, 22256, 22256)

# Remplacement de la frame 22264 par 22258

video = ReplaceFrames(video, 22264, 22264, 22258, 22258)

# Remplacement de la frame 22437 par 22441

video = ReplaceFrames(video, 22437, 22437, 22441, 22441)

# Remplacement de la frame 22438 par 22442

video = ReplaceFrames(video, 22438, 22438, 22442, 22442)

# Remplacement de la frame 22439 par 22443

video = ReplaceFrames(video, 22439, 22439, 22443, 22443)

# Remplacement de la frame 22440 par 22444

video = ReplaceFrames(video, 22440, 22440, 22444, 22444)

# Remplacement de la frame 22454 par 22453

video = ReplaceFrames(video, 22454, 22454, 22453, 22453)

# Retourner le résultat final

return video

Porting:

Code:
function ReplaceFrames(clip source, int start1, int end1, int start2, int end2) {

    # Extraire les segments à garder

    segment1 = source.Trim(0, start1 - 1)

    segment2 = source.Trim(start2, end2)

    segment3 = source.Trim(end1 + 1, source.FrameCount - 1)

    # Assembler les segments

    return segment1 ++ segment2 ++ segment3

}

to Vapoursynth should be easy.
Should be:

Code:
def ReplaceFrames(clip: vs.VideoNode, start1: int, end1: int, start2: int, end2: int)  -> vs.VideoNode:

    # Extraire les segments à garder

    segment1 = source.Trim(0, start1 - 1)

    segment2 = source.Trim(start2, end2)

    segment3 = source.Trim(end1 + 1, source.num_frames - 1)

    # Assembler les segments

    return segment1 + segment2 + segment3

}

So you could save that in a file named replaceframes.py (in your 'Hybrid/64bit/vsscripts'-folder) and then use it in a custom section through:

Code:
import replaceframes

# Remplacement des frames 43125 à 43129 par 43120 à 43124

clip = replaceFrames.ReplaceFrames(clip, 43125, 43129, 43120, 43124)

# Remplacement des frames 43301 à 43304 par 43275 à 43278

clip = replaceFrames.ReplaceFrames(clip, 43301, 43304, 43275, 43278)

# Remplacement de la frame 22261 par 22257

clip = replaceFrames.ReplaceFrames(clip, 22261, 22261, 22257, 22257)

# Remplacement de la frame 22262 par 22257

clip = replaceFrames.ReplaceFrames(clip, 22262, 22262, 22257, 22257)

# Remplacement de la frame 22263 par 22256

clip = replaceFrames.ReplaceFrames(clip, 22263, 22263, 22256, 22256)

# Remplacement de la frame 22264 par 22258

clip = replaceFrames.ReplaceFrames(clip, 22264, 22264, 22258, 22258)

# Remplacement de la frame 22437 par 22441

clip = replaceFrames.ReplaceFrames(clip, 22437, 22437, 22441, 22441)

# Remplacement de la frame 22438 par 22442

clip = replaceFrames.ReplaceFrames(clip, 22438, 22438, 22442, 22442)

# Remplacement de la frame 22439 par 22443

clip = replaceFrames.ReplaceFrames(clip, 22439, 22439, 22443, 22443)

# Remplacement de la frame 22440 par 22444

clip = replaceFrames.ReplaceFrames(clip, 22440, 22440, 22444, 22444)

# Remplacement de la frame 22454 par 22453

clip = replaceFrames.ReplaceFrames(clip, 22454, 22454, 22453, 22453)

clip = replaceFrames.ReplaceFrames(clip, 22440, 22440, 22444, 22444)

return clip

Got no time to test, but this should work.
One could also use https://github.com/Irrational-Encoding-W...emapFrames in a custom section.

Thank you. However I had several issues, I guess they're basic (like core not defined, source not defined, module 'vapoursynth' has no attribute 'get_core', and others). Since it's only for one video I just run a second encoding with Avisynth custom script.

But to get back to the original topic, do you think it would be possible that Hybrid switches from Vapoursynth to Avisynth (or vice versa) during encoding, for example just before output is generated on the script, the video would be reloaded into an avisynth script and further filters would be applied ?

(03.09.2024, 04:16)Selur Wrote: [ -> ]You can use Avisynth filters in Vapoursynth

oh? i haven't seen the avisynth tab in ages and i'd like to use deflicker filters.
is there a way i can still activate the avisynth tab and filters to use them in vaporsynth?

https://forum.selur.net/thread-3835.html hast an example how Avisynth filters can be used.
No, there is no special gui support for this.

Cu Selur

Sorry, fixed the syntax for the replaceFrames.py

Code:
from vapoursynth import core

import vapoursynth as vs

def ReplaceFrames(clip: vs.VideoNode, start1: int, end1: int, start2: int, end2: int):

    # Extract segments to keep

    segment1 = clip[:start1]  # From the start to the frame before start1

    segment2 = clip[start2:end2 + 1]  # From start2 to end2

    segment3 = clip[end1 + 1:]  # From the frame after end1 to the end

    # Combine the segments

    return segment1 + segment2 + segment3

then call it in Hybrid under "Filtering->Vapoursynth->Custom->Insert before->ReplacBlackFrames"

Code:
import replaceFrames

# Remplacement des frames 43125 à 43129 par 43120 à 43124

clip = replaceFrames.ReplaceFrames(clip, 43125, 43129, 43120, 43124)

# Remplacement des frames 43301 à 43304 par 43275 à 43278

clip = replaceFrames.ReplaceFrames(clip, 43301, 43304, 43275, 43278)

# Remplacement de la frame 22261 par 22257

clip = replaceFrames.ReplaceFrames(clip, 22261, 22261, 22257, 22257)

# Remplacement de la frame 22262 par 22257

clip = replaceFrames.ReplaceFrames(clip, 22262, 22262, 22257, 22257)

# Remplacement de la frame 22263 par 22256

clip = replaceFrames.ReplaceFrames(clip, 22263, 22263, 22256, 22256)

# Remplacement de la frame 22264 par 22258

clip = replaceFrames.ReplaceFrames(clip, 22264, 22264, 22258, 22258)

# Remplacement de la frame 22437 par 22441

clip = replaceFrames.ReplaceFrames(clip, 22437, 22437, 22441, 22441)

# Remplacement de la frame 22438 par 22442

clip = replaceFrames.ReplaceFrames(clip, 22438, 22438, 22442, 22442)

# Remplacement de la frame 22439 par 22443

clip = replaceFrames.ReplaceFrames(clip, 22439, 22439, 22443, 22443)

# Remplacement de la frame 22440 par 22444

clip = replaceFrames.ReplaceFrames(clip, 22440, 22440, 22444, 22444)

# Remplacement de la frame 22454 par 22453

clip = replaceFrames.ReplaceFrames(clip, 22454, 22454, 22453, 22453)

clip = replaceFrames.ReplaceFrames(clip, 22440, 22440, 22444, 22444)

You mean that Hybrid does a multipass encoding, first for example, it uses Avisynth to filter the source, saves the output into some lossless compressed file, then uses Vapoursynth to filter that output and encodes it to whatever output was chosen?
Sorry, no. Hybrid atm. does not support this, and rewriting Hybrid to do this seems too much work for the gain.

Cu Selur

Yes basically, because I think that's how it works between filters : reusing the last video and re-encoding it.
But if it's too complicated there's no need to bother, we just have to import the video again.
