And... I'm back, 'cause I have to encode more trailers for the website.
I'm experimenting a bit with -row-mt -tile-columns -tile-rows -tiles and -cpu-used.
For FULL HD 25p contents, what do you think it's the sweet spot between quality and speed?
I'm trying with:

on my PC (an old i7 5930K 6c/12th) and it definitely improved things. CPU usage is much higher at 68% and I'm seeing 22fps vs the original 0.8fps.
and it's about the same on a 56c/112th Xeon server, with 23fps as top speed and 11% total usage:
Did I get the settings right? Is it gonna affect the quality in a significant way or can I just set this as default?
I mean, 23fps is definitely way more acceptable than 0.8fps as it's at least almost 1:1 (25fps would be realtime).
