In the meantime I found and created my own solution. I have a goo d avisynth -script, which find scenes (very reliable) an d list them in a textfile. Then I made a tool which reads the textfile and creates blendframes (with running an avisynthscript) of last an d first frame at scene change. So I replace all mixed frames with blend frames.
Viewing post in no frameinterpolation at scene change that's right but...
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.
