Hash: SHA256
param->tuQTMaxInterDepth = 1;
param->tuQTMaxIntraDepth = 1;
can be removed from all presets since they are already default
default "param->lookaheadDepth = 40"
veryfast has "param->lookaheadDepth = 10"
- -> seems like superfast and ultrafast should get
"param->lookaheadDepth = 0" or "param->lookaheadDepth = 10"
