    Recently I have decided to try out the Avisynth VHS effect to get a nice retro effect to an animation that I made. However, when I drag the effect into VirtualDub, I just get this annoying error:

    Avisynth open failure:
    Script error: expected
    (C:/Users/Owner/OneDrive/Desktop/Newfolder/EFFECT.avs, line 21, column 28)

    I also didn't know where else to post this thread cause I'm a newbie. But any help would be nice.

    The line in the original effect VHS avs sample was this
    loss=imagesource("mask\hsync_%03d.bmp",end=127).as sumefps(2997,100).loop(1000)

    This may take a while to debug

  5. Is there are series of BMP files with filenames like:

    hsync_000.bmp
    hsync_001.bmp
    ...
    hsync_127.bmp

    in a folder called mask where the script is?

    Hi jagabo -
    yes. The sample archive provided all the ancillary files in order for the example script to work

    Well now I just got a different error: AVI Import Filter error: (Unknown) (80040154). I honestly don't know what to do .
    Quote Quote  
  8. That is the error message you get when AviSynth is not installed. Be sure you have the right bitness. If you're using a 32 bit editor/encoder you need 32 bit AviSynth and 32 bit filters. If you're using a 64 bit editor/encoder you need 64 bit AviSynth and 644 bit filters.

    I'm using Virtual Dub 64 bit. Does that mean I need to use Avisynth 64 bit as well? And I can't find anywhere to download Avisynth 64 bit that doesn't lead me to a virus.

    Look at the software section of this site.

  11. With old software like that it's best to stick with 32 bit. But if you really want to use 64 bit AviSynth I recommend you use AviSynth+ instead of the older AviSynth.

    From this Youtube video:

    https://www.youtube.com/watch?v=ny1nVXibozs

    I got a link to

    https://mega.nz/file/6MdHFIaa#gKtnvxoyCKpZXNxZve1TmCtd__gwNzZDL0-6WrWjt5k

    The AviSynth script in that link worked with both 32 bit and 64 bit AviSynth+ (and 32 bit and 64 bit VirtualDub2).

    At least if you download and install Avisynth+, you have the 32 and 64 bit available, dependent on the bitness of the host app

    When I try to download Avisynth plus, Windows says its a virus.. Is this true? Or should I just go ahead and download it anyway?

    Edit: To be more specific, It says "Microsoft Defender Smartscreen prevented an unrecognized app from starting. Running this app might put your PC at risk."

    Smartscreen is just a file reputation tool, Microsoft doesn't know about this file.
    It's fine.

    Okay, I downloaded Avisynth + and restarted my computer. However when I dragged the EFFECT into VirtualDub2, I got another error:

    Avisynth open failure: AVIFileSource: couldn't open file 'baseband artifect.wav'
    (C:/Users/Owner/OneDrive/Desktop/New folder/EFFECT.avs, line 69.)

    Is this a script problem? I"m not sure.

    It's looking for the wav file that is included with the VHS effects package. A number
    of other files should be there also:

    It works. However Virtual Dub keeps crashing and it makes a weird noise when I play the video.
    Quote Quote  
  18. If you're using VDub to play the video, don't. It's not a good player. If there's audio in the script, play the script. If the video and audio are named the same (Movie.avi, Movie.wav, for example), play the video and the audio should also play. Maybe that depends on the player, not sure.

    I assume you mean VDub as in Virtual Dub? And I think Avisynth is only compatible with Virtual Dub. I'm not sure if it's compatible with any other video player. The problem I'm having is that when I drag the effect script into virtual dub and play the video, the video won't make any noise except a high pitched noise. When I pause the video, Virtual Dub crashes.

    Try dragging the .avs file to a player such as mpc-hc and see if it works.

  21. What are the characteristics of your source video , in terms of dimensions, codec, colorspace ? You can check with mediainfo

    You can try another source filter, instead of DirectShowSource . If it's an AVI , try AVISource, or use FFVideoSource (ffms2 plugin)

    The script as written expects the audio of the source file to be sampled at 48000. If it's not some changes to the script are necessary.
    Here's a script that works, compare to yours. My version uses the Lsmash source filter, you can download it from here if you don't have it.

    The lines beginning with # are just comments.
    The other stuff in that area are some changes I made to get it to work.
    Post the mediainfo (text view) report of your source video here in the thread

    Is your source actually named "video.avi" ?

    I haven't used MediaInfo at all before but yes, my source is named video.avi to keep it simple. I had also followed a tutorial on Youtube as well and it said to rename the script from Nyan_Cat_Sample.avi to video.avi.

    Here are the pictures. Is this what you mean?

    This script will not work as-is when the source audio is ADPCM audio.
    Also the sampling rate should be 48000 otherwise you modify the script even more
    I don have such a video to try myself. Can you post a clip ?

    You think wrong.
    The problem I'm having is that when I drag the effect script into virtual dub and play the video, the video won't make any noise except a high pitched noise.
    I already suggested not using VDub to play your video. But that's the least of your problems. The audio and video codecs are what's screwing you up. I'd suggest dumping everything in your bloated script except the source filter and just try to open the video alone to begin with. I don't think AviSource will work but one of the others suggested should.

    What do you mean by dumping everything? And what is a source filter? And I tried to use MPC-HC to play my video instead of VDub with the effect but it crashed as well when I dragged the effect in. It played the video by itself just fine.

    Ahhh nevermind I finally found a fix! I had to change the audio codec from adpcm to aac. Thanks for all the help/advice, though. I appreciate it. Sorry If I'm not that good at coding. I only took like one coding class last year (my freshman year high school).

    Yes, the script is designed for the XP days when most were more likely to have a VFW codec installed so Avisource will work.
    Changing the source filter to directshowsource opens in Virtualdub but crashed when you attempted to play it.
    Seems to be this line that uses supereq:

    Code:
    #Realistic: Equalization uses supereq. Normally use this:
    vidaudio=converttomono(originalaudio).amplify(0.3).supereq("vhs.feq")
    
    #Compatibility: If the above create error, use this instead: (Not realistic)
    #vidaudio=converttomono(originalaudio).resampleaudio(16000).amplify(0.7).resampleaudio(48000)
    When you comment it out and enable the compatible workaround it works fine.
    I found shibatch.dll in my plugins folder, I assume that's the relevant dll.
    Not sure what is wrong with supereq

    EDIT - I figured it out - you have to use ConvertAudioToFloat() on the audio before calling supereq().
    Otherwise it sends a horrible screeching noise to the host program which eventually crashes
