Yes- it's some technique which can be found is some other solutions.
The main problems is high motion scenes and also low fps sources 24p,25p, 30p.
Most of them have high motion burr, so instead of hard edges between some elements there are blurred areas. In these places quality suffers a lot- there are big artefacts.
I don't know if phase plane correlation can help, but it's used in other high-end solutions.
