I'm wanting to mess with the MainConcept MPEG2 encoder in Vegas Pro. I'm planning on using it with one of my Avisynth scripts without encoding with ffmpeg first. I looked it up and apparently you can use AVFS to mount a script for use in Vegas, but I cannot get it working.

I downloaded Vapoursynth portable so I can get AVFS.dll and the PFM exe, but whenever I try to mount a script, I keep getting this error:

I have the PFM exe in C:\Windows, which is in my PATH, so I'm not sure why it's not working. Is there a fix for this? I'm running Windows 11.

PismoFileMount got to be installed from its installer, IIRC, meaning registered, so that OS knows about it.
Which version works under which OS/NLE combo, this may be only tried.
Just putting the .exe into path might not be sufficient.

I forgot to mention this, but I installed PFM before I got the EXE's from the Vapoursynth folder, and it still didn't work. I dunno why it's not seeing it.

Unable to load may mean also other errors. May be try to open command prompt window with administator rights ?

The trick which helped sometimes was to install an older version of PFM. 1.7.3 ?
Once I had success under Win7, no success under Win10, I can not speak of Win11.

Thanks! I installed build 192 and it works! But I imported the fake AVI in Vegas and it doesn't look right. It might be something with my script.

Probably wrong pixel format

Try


ConvertToRGB32(interlaced=true)
