So i would definitly say it's safer to feed srestore with a clean detection clip. From that point of view, didee's suggestion looks very reasonable to me.

I am still trying to understand what is best for the detection clip. I encoded the same clip using a simple bob(0,0.5) as dclip, using yadif(mode=1, order=1) as dclip, using the 3 stage bob parameters as dclip (couldn't get reduceflicker=false to work so had to kill that part), and using only the tgmc bob input.
Stack of those 4 clips + source + avs can be found
here. I included the frame number on each frame so that we can see which frame was chosen by srestore. I do see that sometimes a different frame is chosen for the TGMC input and sometimes different for yadif and sometimes different for bob(0,0.5) and other combinations. It looks to be picking either the odd or even frame. I don't know which is
right.... I don't see blends in any of the outputs. Using a detection clip definitely results in faster detection for Srestore though (compared to using the TGMC bob as input).
