Using Videofreds "Capturing and restoring old 8mm films" with Wolverine scanner

[spotty]

Hi, I'm trying to use Videofreds "Capturing and restoring old 8mm films" Avisynth scripts with the output from a Wolverine Pro scanner.
I realise this isn't ideal as the output is MP4 format and has undergone some lossy compression. It does however have 1 frame for every 1 frame in the original film, despite the metadata in the file saying an arbitary 20fps (or 30fps for the non-pro version).
I would be happy with lossless conversion from MP4 to some suitable AVI format (not just re-containered) as a separate stage.
Even better, a way to change the start of Videofreds scripts so that they work with the MP4 file, without adding loss, and retaining the other features done by the lines ->
....
film= "C:\Users\You\Documents\Yourfile.avi" # source clip, you must specify the full path here
.....
source= AviSource(film).assumefps(play_speed).trim(trim_begin,0).converttoYV12()
trimming= framecount(source)-trim_end
source1= trim(source,0,trimming)
....

You can use LSmash as the source filter

LSmashVideoSource() for MP4

....
film= "C:\Users\You\Documents\Yourfile.mp4" # source clip, you must specify the full path here
.....
source= LSmashVideoSource(film).assumefps(play_speed).trim(trim_begin,0).converttoYV12()
trimming= framecount(source)-trim_end
source1= trim(source,0,trimming)
....

Thanks, that worked well.
