Wrong. Unless you explicitly pass "--slow-firstpass", which my GUI definitely does not do, x264 will automatically run the first pass with "turbo" settings.
So it's perfectly fine to pass the same settings for both passes and let x264 decide which settings can be lowered during the first one 
Of course it's up to you. You can always add the "--slow-firstpass" parameter to the "Advanced Options" edit box, if you really want a SLOW first pass. |
I understand. But why do i get only ~4,5fps in 1 pass with your Gui ?
With all other guis or via cmdline i get ~15fps with the same Settings/Source ?
Log : ( from 500 frames sample, but its the same Speed with the Full Source)
