If you're interested in seeing the discussion we've had up to this point it's at AVS Forum
here.
I've added blend=false for the next release since that seems like a good idea.
jmac698, please feel free to convert the original video with a different function like blendfps or convertfps to see the difference.

InterFrame -
BlendFPS
I should also update those sample videos since they are from an earlier version of the script. I will post back when they are updated.
