Working on a scene, i´ve tried to use frame blending and it produces a better result…
A better result than what?
And another question, why the frame blending is not removing all the distortion/iterlacing?
Frame blending is not a solution to combing. It’s the worst thing you can do to a video in almost all circumstances. If you are seeing combing and the video is 29.97fps, it’s far more likely that you need to perform an inverse telecine – for example, by using TIVTC with AviSynth.
