VirtualDub/AVISynth VHS Effect Script Error

[ElmoRocks05]

Well, I'm trying to use the AVISynth VHS effect after such a long time. It did work this first time, but now I'm getting this annoying error:

An out-of-bounds memory access (access violation) occurred in module 'VirtualDub64'...
...reading address FFFFFFFFFFFFFFFF...
...while running thread "Processing" (thread.cpp:197).

And here the crash debug information if you need it: https://mega.nz/file/qSwWTCxY#Oj55-D2FwQTbt9nBZFYfeGSkvNaDvvX52jDG5vos238

Can anyone please fix it for me? I haven't uploaded anything on YouTube in a long time because I'm making this video since I graduated from high school this week. So, if anyone can fix it for me, it would be awesome.

What is the "VHS effect"? Is this an AviSynth plugin? If yes, where can I get it? Is it listed in External filters or even AviSynth+ x64 plugins (which you would need in VirtualDub64)?

[Gramps]

My first guess would be that the "VHS Effect" Avisynth filter is 32-bit, and that the first time that you ran your AVS script was in the 32-bit version of VirtualDub, but now are trying to run it in the 64-bit version of VirtualDub. In your VirtualDub folder, run the 32-bit version of it by clicking on VirtualDub.exe, rather than VirtualDub64.exe, and open your AVS script with it.

[ElmoRocks05]

This is the script I'm talking about: https://www.youtube.com/watch?v=qytlv9XfzYw

Also, I already tried the 32-bit way, and it still won't work. I just don't understand what the hell is going on. I'm getting sick of it.......

I suspect you have some other issues beyond this script because it doesn't use any external function,
so it should work on Virtualdub2 32 or 64 bit, assuming you have the right version of Avisynth installed
I got it to work by substituting Avisource with lwlibavvideosource and lwlibavaudiosource (which is an external filter)
with the 32 and 64 bit source filters (LSMASHSource.dll) in their proper folders.
Also used my own source video.

For avisynth I'm using Avisynth+, the latest version 3.61, came out today

#SOURCEVIDEO=AVISOURCE("Nyan_Cat_Sample.avi").bilinearresize(392,480).resampleaudio(48000)
vid=lwlibavvideosource("C:\Users\Public\Videos\demo-misc\Solid Geometry (Short 2002 #).mp4")
aud=lwlibavaudiosource("C:\Users\Public\Videos\demo-misc\Solid Geometry (Short 2002 #).mp4")

sourcevideo=audiodub(vid,aud)

Also towards the end of the script:

#noise=avisource("noise-preprocess.avi").bilinearresize(400,480).loop(300)
noise=lwlibavvideosource("noise-preprocess.avi").bilinearresize(400,480).loop(300)

EDIT May 2023 - for usage of this script it's better to stick to Avisynth 2.5-2.6,
there are some strange issues when running under Avisynth plus

[ElmoRocks05]

Uh, I don't know how to do that.

[davexnet]

Uh, I don't know how to do that.

Install Avisynth+ as mentioned, and download the Lsmash source filter
https://github.com/HolyWu/L-SMASH-Works/releases/

Extract the dll's and place the 32 bit plugin in here

C:\Program Files (x86)\AviSynth+\plugins+

and the 64 bit plugin here

C:\Program Files (x86)\AviSynth+\plugins64+

Edit the script as necessary and then drag the script icon onto the Virtualdub2 window

[ElmoRocks05]

I don't know how to do the code or script stuff. I think I'm doing it wrong because I'm now getting an error when I put the script onto VirtualDub. This is getting really stressful.

[davexnet]

Just edit the script (effect.avs) similar as I showed in the example above (post 5), open Virtualdub2 and drag the effect.avs icon
into the Vdub window. It will open and the video will display or you'll get an error message

[ElmoRocks05]

Well, I got this error.

And this is how I edited the script:

Did I do it wrong?

[davexnet]

Did you install the function as I mentioned in post 7 ?

You can see here the 64 bit plugin folder where I placed the 64 bit version of Lsmashsource.dll

[ElmoRocks05]

Yes.

[ElmoRocks05]

Did you install the function as I mentioned in post 7 ?

You can see here the 64 bit plugin folder where I placed the 64 bit version of Lsmashsource.dll

Oh, wait a second! I don't think I installed AviSynth+! 0_0
You put the link to the regular AviSynth on the other reply mentioning it and I must have accidentally downloaded and installed it. I'll try again and let you know what happens.

[ElmoRocks05]

You can see here the 64 bit plugin folder where I placed the 64 bit version of Lsmashsource.dll

And another thing I didn't realize is that the plugins are supposed to be in the AviSynth plugins folders! But was I supposed to put them in the VirtualDub plugin folders too? 'Cause that's what I did.

Well, I am still getting an error. I just don't know what I'm doing wrong. Do I put the code exactly as it is on the script or do I change it to suit my needs?

[poisondeathray]

You have to change it to suit your needs

Change the path to match your actual file paths and video names

[davexnet]

Yes, "solid geometry" is a short film I have on my hard drive. You can't access it from where you are

[ElmoRocks05]

Well, now I'm getting this error.

[davexnet]

Use mediainfo on your video file to find the sampling rate of the audio stream

The message is telling you what's wrong, the sampling rate of your audio does not match the "noise" sample (WAV file) in the
VHS effects folder. The script is trying to mix in some broadband noise into your files audio to make it sound crappy

When you find out what it is you can change this line so that the resampleaudio matches your file

audnoise=wavsource("baseband artifect.wav").resampleaudio(48000).loop(600)

[davexnet]

The error is related to this statement, which joins your video to a short blank clip to mimic the VHS lead in:

player+final

To make it work, modify the audio_rate on this line to match your video:

player=BLANKCLIP(length=60, color=$2222DD, fps=29.97, CHANNELS=1, audio_rate=48000).converttoyv12

YES! It worked! Thanks, man! I'll let you know if it stopped crashing or not.

Ugh, it's still crashing?! I don't know how that's possible! I followed everything you said!

[davexnet]

The script just process the input and serves the frames, but if it is crashing during the encoding other
things are involved.
I can't tell what you did in Virtualdub2 and what settings you used, you haven't provided any info at all.

[ElmoRocks05]

Well, I just converted the video file to AVI and put it into the script. Then I put the script onto VirtualDub2 and tried saving as an AVI file. Then it started crashing. That's pretty much all I can tell you.

[davexnet]

try setting the video/Audio compression codec
at the top
video/compression/x264-8-bit/configure/load defaults/OK out
Audio/Full processing/
audio/Compression/FFmpeg AAC/OK out

File/save as/save as type/ > choose either MKV or MP4, your choice (this is preferable to AVI)

[ElmoRocks05]

Well, it managed to save the video, but now the audio is screwed up.

[ElmoRocks05]

Well, it managed to save the video, but now the audio is screwed up.

Hello?

[davexnet]

Well, it managed to save the video, but now the audio is screwed up.

Hello?

I'm back. What does "but now the audio is screwed up" mean. How do expect anybody to respond to that?

[ElmoRocks05]

Well, the music is gone and replaced with nothing but static.
