My concern is in increasing my Avg QP, I am almost always above 24, whereas before with version 3.4 + 20 I managed to have my Avg QP below 20.
here are the parameters used for the3.5_RC2 : --scenecut-aware-qp 3 --masking-strength 500,2,0,200,-1,-1 **** I also tested: --scenecut-aware-qp 1 --masking-strength 300,2,2 *** --scenecut-aware-qp 3 --masking-strength 500,5,6.5,100,-1,-1
for the rest of the parameters : --rd 6 --rskip 2 --deblock -3:-3 --cutree --ctu 64 --min-cu-size 8 --bframes 4 --b-adapt 2 --rc-lookahead 60 --ref 4 --limit-refs 2 --merange 57 --subme 7 --aq-mode 4 --aq-strength 0.70 --me 3 --psy-rd 2.10 --psy-rdoq 1.35 --gop-lookahead 54
I tested by increasing my --bframes and reducing my --gop-lookahead, it is a little better but nothing more.
In 3.4 + 20 I had this in parameters: --scenecut-aware-qp --scenecut-window 500 --qp-delta-ref 6 --qp-delta-nonref 7 and my QP was impeccable
Thank you for your help
Have you tried using just --scenecut-aware-qp 3 --masking-strength 500,-1,-1 ?

Also, what happens to quality?
