Load 64bit Avisynth filter in Vapoursynth

Fri, 30 Aug 2024 16:17:33 +0200

On Windows, it's possible to load and use Avisynth filters (!not scripts!) inside Vapoursynth.
You can do this in Hybrid inside 'Filtering->Vapoursynth->Custom' sections.
Here's an example how to load and use DeSpot:

core.avs.LoadPlugin("F:/Hybrid/64bit/Avisynth/avisynthPlugins/despot.dll")

# requires colorformat YUV420P8

clip = core.avs.DeSpot(clip, median=False,p1=24,p2=12,pwidth=6,pheight=5,ranked=True,sign=0,minpts=0,maxpts=0,p1percent=10,dilate=1,fitluma=True,blur=1,tsmooth=0,motpn=True,seg=2,color=False,mscene=0,mthres=16,mwidth=7,mheight=5,show=0,show_chroma=False,interlaced=False)

return clip

Explanation:

core.avs.LoadPlugin("F:/Hybrid/64bit/Avisynth/avisynthPlugins/despot.dll")

Loads the DeSpot filter from "F:/Hybrid/64bit/Avisynth/avisynthPlugins/despot.dll".
Note that I use slashes (/) instead of backslashes (\) and you need to adjust this path to wherever the filter you want to use is located.

# requires colorformat YUV420P8

Lets Hybrid know that the filter only supports YUV420P8 (<> 8bit YV12). This should be adjusted according to your needs and the capability of the filter.

clip = core.avs.DeSpot(clip, median=False,p1=24,p2=12,pwidth=6,pheight=5,ranked=True,sign=0,minpts=0,maxpts=0,p1percent=10,dilate=1,fitluma=True,blur=1,tsmooth=0,motpn=True,seg=2,color=False,mscene=0,mthres=16,mwidth=7,mheight=5,show=0,show_chroma=False,interlaced=False)

calls the filter with the signature from the DeSpot-Avisynth Page.
Note that Vapoursynth uses 'True' and 'False' instead of Avisynths 'true' and 'false'.

return clip

returns the clip.

Hope, this helps to load 64bit Avisynth filters in Hybrid if need be.

Convert to 60fps

Mon, 21 May 2018 08:05:37 +0200

Here are possible ways to get it to 60fps.

Start Hybrid
Set 'Base->Processing->Audio' to 'passthrough all' since we want to keep the audio as it is.
Choose the encoder you want 'Base->Processing->Video' for simplicity I kept it set to 'x264'
Configure the encoder the way you want. (I just changed 'x264->Base->General Settings->Encoding mode' to 'constant rate factor (1-pass)', but depending on your resolution you might need to use a higher value than the default 4.1 under x264->Base->Restriction Settings->AVC Profile/Level.)
Set default folders (Config->Path->Default ...)
Enable 'Config->Internals->Handling->Ignore all input timecodes', so that Hybrid will ignore the time codes and not try to keep them for the output
Enable 'Base->Generate' so that Hybrid will automatically set the output name
Now there are multiple different ways to interpolate the frames.
1. Without Avisynth and Vapoursynth, using FFmpeg
  - Now one can either set:
    - 'Filtering->Speed Change->Speed Settings->Interpolate frame rate' to '60fps', which will interpolate frames to archive the wanted frame rate, or
    - 'Filtering->Speed Change->Speed Settings->Scale output frame rate' to '60fps', which will insert duplicate frames to archive the wanted frame rate.
2. Using Avisynth (make sure Filtering->Support is set to 'Avisynth'), don't try to convert 4k+ video with 32bit Avisynth.
  - Here one again has multiple options, all under 'Filtering->Avisynth->Frame->FPS adjust'. Depending on the source some times one or the other interpolation method offers the best results.
    - When using SalFPS3, your need to set 'Filtering->Avisynth->Frame->FPS adjust->SalFps3->Fps' to '60' and depending on your source your will want to tweak some of the other settings.
    - When using Interframe, your need to set 'Filtering->Avisynth->Frame->Interframe->Target frame rate' to '60', depending on your system you might also want to enable 'GPU' and depending on your preference you will likely want to set 'Tuning' and 'Override Algo.'
    - When using FrameRateConverter, there are tons of settings to play with, can't really recommend anything in general.
3. Using Vapoursynth (make sure Filtering->Support is set to 'Vapoursynth')
  - Again there are multiple choices to archive 60fps, all under 'Filtering->Vapoursynth->Other->Frame Interpolation'
    - 'Interframe/SVP', basically the same as in Avisynth. Remember so set 'FPS' to '60'
    - 'MVToolsFPS', remember to set 'TargetFPS' to '60'
    - 'RIFE', chose model, set Target FPS (nu,/den) to 60/1
    - 'FrameRateConverter': same as for Avisynth (but has more presets)
    - 'TorchRIFE' same as 'RIFE', but with more options (requires torch-addon for Hybrid)
    - 'RIFEmlrt' same as RIFE, but with support for different Backends. (requires vsmlrt-addon for Hybrid)
Create a job for the current settings. (Base->Add to queue)
Start the job processing. (Jobs->Queue->Start)

Note that each of the methods has it's downsides and it's 'normal' to get artefacts when interpolating frames.

Simple container change

Sun, 29 Apr 2018 08:14:07 +0200

Sometimes one just wants to change the container,...

Change the container (passthrough all audio, video, subtitle streams):
1. Start Hybrid
2. Enable Config->Automation->Passthrough streams->Subtitle
3. Set 'Base->Processing->Audio' to 'passthrough all'
4. Set 'Base->Processing->Video' to 'passthrough'
5. Load Source ('Base->Open File')
6. Set the output ('Base->Output File') and make sure it has the extension of the new container.
7. Add job to queue ('Base->Add to queue')
8. Start the job processing ('Jobs->Queue->Start')
Change the container (passthrough all audio, video, no subtitle streams):
- same as Change the container (passthrough all audio, video, subtitle streams, but skip step 2.
Change the container (passthrough video, but just audio and subtitle streams of specific languages):
1. Start Hybrid
2. Enable Config->Automation->All subtitle only add/extract' and select the languages you want in the drop-down menu.
3. Enable Config->Automation->Limit audio passthrough/auto add all' and select the languages you want in the drop-down menu.
4. Set 'Base->Processing->Audio' to 'passthrough all'
5. Set 'Base->Processing->Video' to 'passthrough'
6. Load Source ('Base->Open File')
7. Set the output ('Base->Output File') and make sure it has the extension of the new container.
8. Add job to queue ('Base->Add to queue')
9. Start the job processing ('Jobs->Queue->Start')

Enforcing vfw decoding through Avisynth

Sat, 27 May 2017 07:38:46 +0200

Sometimes there are .avi files which can't be decoded through libav/ffmpeg, but there are vfw decoders.
In case those vfw decoders are installed Hybrid can use them through AviSource()-Avisynth filter.

To enforce the usage of Avisynth and the AviSource filter in Hybrid to the following (before loading your source file):

activate "Config->Internals->Avisynth->Always use Avisynth"
This forces Hybrid to use Avisynth
deactivate "Config->Internals->Avisynth->No Avisynth during Preview"
This allows Avisynth decoding during the normal preview; only needed if the 'Avisynth Preview' isn't enough)
activate "Filtering->Avisynth->Misc->Prefer AviSource for avi input"
This tells Hybrid to check the vfw decoders in the system and use AviSource whenever the source is .avi and there is a vfw decoder installed.

Cu Selur

Ps.: Not that Hybrid uses 32bit Avisynth so even on 64bit system only 32bit vfw decoders are used.

What is this sub-forum about?

Hoi,
since I form time to time post small step-by-step guides for users to help them I thought it might be a good idea to collect them in this forum so new users will be able to find them more quickly.

Note: Normal users can't create new threads/topics inside this sub-forum.
