FINAL 5

# The ffdshow VfW interface must be installed to decode the source AVI, which is encoded with FFV1. See http://ffdshow-tryout.sourceforge.net/
# This script also requires MPASource, info at http://avisynth.org.ru/docs/english/externalfilters/mpasource.htm
# The rest of the filters are internal
# Expanded a bit for clarity, though it's been years since I've used AviSynth so my syntax could be a bit rusty

# We speed up the source framerate by 1.5x to match the original video and have it more in tune with the speed of the song
# It's then converted back down to standard NTSC because this is what Youtube expects. changefps() looks nicer than convertfps() in this case.
# To create a native 36 fps video, remove the changefps line and scale all frame offsets by 1.5.
