# An AviSynth filter to detect and replace duplicate frames
# with a motion-interpolation of the adjacent frames.

# mod 2021-07-10 by Selur
# mod 29 Oct 2021, Added ThreshIs8Bit arg. ssS. https://forum.doom9.org/showthread.php?p=1956020#post1956020

# - mod by Selur to parametrize Luma Difference Threshold
# https://forum.videohelp.com/threads/402416-repair-Videos-with-duplicates-and-dropped-frames#post2624936
#
### Requirements ###
#-------------------
# Avs v2.60/+
# MvTools2 (https://github.com/pinterf/mvtools)
#
### Arguments ###
#-----------------
# thresh (default=0.1) - Luma Difference Threshold
#    Lets you specify how different a frame has to be (from the previous frame)
#    before it's considered not to be a duplicate, and therefore not replaced with a motion interpolated frame.
#    If the threshold is too small, some duplicate will not be replaced.
#    If it's too large, many frames which aren't duplicates (just having very small motions) will be replaced.
#    (explanation by jagabo on VideoHelp)
#
# ---------------
# ThreshIs8Bit, Default False, If True and bit depth > 8 bit, then thresh is converted to current bit depth threshold.
### Changelog ###
#---------------
# Changed requirements: from MvTools to MvTools2 (johnmeyer)
# Parametrized Luma Difference Threshold (Selur)
# ssS: Added Bool arg "ThreshIs8Bit", default = False.

You wanna update it on your github JKyle ?

EDIT:
Added arg, Bool "ThreshIs8Bit", default=False.

ThreshIs8Bit, Default False, If True and bit depth > 8 bit, then thresh is converted to current bit depth threshold.

If true, Eg, if bit depth = 10, then multiply thresh by 4 : if bit depth 16 then mult thresh by 256.
