Bei PRESET DEFAULT verhält es sich ganz genauso, kein Unterschied wie anfangs angenommen und tf-level hat auch keinen Einfluss.
Einzig lookahead-level 1 und 2 scheinen adaptive quantisation auszuhebeln.

Sieht irgendwie schwer nach Bug aus, es sei denn die höheren lookahead level können Wasser zu Wein machen, und erreichen, wenn tf-level ausgeschaltet/auf 0 ist, bei gleichbleibender Qualität Bitraten, die lookahead-level 1/2 nichtmal mit aq-strength 1 erreichen und machen adaptive quantisation überflüssig...
