Such a showoff ;)
Now that's a good interim solution! To be honest, looking at the avisynth Licence it may be an option to bundle it into DainApp with the scripts you created.
Either that or like you suggested before, implement another ML algorithm to pick out and replace those mixed frames with blends. In a way that almost seems harder than the solution you've come up with though.
And sorry if my Hardware explanation was too simple for you, I figured I'd write it as though you didn't know much about PC hardware and then other people could use it too.
