There's nothing wrong with blacks being below 16 and whites above 235. Happens all the time. With :
LanczosResize(624,352)
ColorYUV(Analyze=True)
Limiter(Show="Luma")
you get the first picture below left from frame 199. The red dots show values below 16 (and barely below at that). Although it's quite dark, it's not really out of the ordinary for a really dark scene. The second picture below right is with:
YLevelsS(0,10.0,255,0,255)
Tweak(Bright=-14,Cont=0.93,Coring=False)
LanczosResize(624,352)
ColorYUV(Analyze=True)
Limiter(Show="Luma")
In neither of your two samples did I see any blown whites, although maybe they do blow out elsewhere.
