Ah, ok. that explains it. I thought most simple CLI options means its the
most likely good default. 

Any deinterlacer thats parallelized like the codecs (x264 etc..) ?

No ffmpeg/CLI involved in that theory. 
Just download SD and HD versions of some current ARD/ZDF TV production and check it
(i used vlc single step).  Oh well, its still a lot easier than dealing with
NTSC/ATSC telecine problems except that its easier to find recipes on the web
for ATSC/NTSC coding.
