Installing avisynth on Ubuntu 16.04

[psip]

I have installed hybrid according to the instructions provided on https://forum.selur.net/showthread.php?tid=18 on Ubuntu 16.04

I cannot figure out how to install the avisynthExtension_180127.7z package downloaded from http://www.selur.de/downloads. There is no avisynth tab no matter what I do.

I want to convert videos to a higher framerate. I am assuming that vapoursynth does not support this. Any help is appreciated.

I am assuming that vapoursynth does not support this

Vapoursynth does support this and even Hybrid without Avisynth or Vapoursynth can do that using "Filtering->Speed Change->Interpolate frame rate" which uses the ffmpeg frameratefilter-filter from ffmpeg.
That said, the Avisynth and Vapoursynth frame rate interpolation filters offer better quality and more options.

That side, you should not have to install the avisynthExtension manually.
Adding the repository, updating the packages using:

sudo add-apt-repository ppa:djcj/hybrid
sudo apt-get update

and using:

sudo apt-get install hybrid hybrid-tools hybrid-avisynth-extension hybrid-vapoursynth-extension

should install all needed stuff for Hybrid with Avisynth and Vapoursynth support.

"Vapour->Other->Frame Interpolation" offers two different methods for interpolation, 'Interframe/SVP' and 'MVToolsFPS', I hope djcj included the required dependencies for it (haven't checked).

A list of all VS extensions can be found here: https://github.com/darealshinji/vapoursy...er/plugins
I haven't upated it in a while though.

Thanks for the quick reply. It has clarified a lot of my doubts regarding Hybrid. I am able to increase framerate by interpolation.

However, I have two issues now:

1. I am unable to use avisynth. It is as if it was never installed. (Please refer the screenshot in the attachments)
I'm guessing this has something to do with the non-windows avisynth extension on selur.de/downloads

2. Vapoursynth keeps crashing. Log states that the .stats file was not created and aborts as soon as the first pass starts.

btw, what does scene change next to interpolate framerate in speed change mean?

[Selur]

Framerate filter -> see link above in the FFmpeg documentation.

Regarding the crash:
Does the Vapoursynth preview work with the settings and source?
I case it does create a DebugOutput level 9 of the job Processing. (See sticky)

Regarding Avisynth:
You'll have to wait for feedback from djcj dir that.

Vapoursynth preview does not work either. The error shown in VSedit is
                       'Failed to open the file --preview-only'

The log in VSedit read

                                        Failed to load vapoursynth script library!
                                        Please set up the library search paths in settings.

Do I need to have vapoursynth installed in advance before installing hybrid-vapoursynth-extension?

[Selur]

nope,...
What does the Vapoursynth script look like?
What is the path to vsedit?
Hybrid uses a modified vsedit version, which I probably (djcj?) should be in the hybrid-bin folder.
The normal vsedit, doesn't allow to be controlled through another program (here Hybrid).

[psip]

It has two lines of code:

import vapoursynth as vs
core = vs.get_core()

I have attached a screenshot for the same too

[Selur]

That looks like the wrong vsedit is used, which doesn't load the generated script.
-> you will have to wait for djcj to look at this.
Vsedit needs to be from https://github.com/Selur/vapoursynth-editor
