The tutorial doesn't cover the x264 settings in length since the settings there are mainly user choices and depend on the resolution and bitrate. 
Simply set:
a. x264->Base->Restriction Settings->AVC Profile/Level from the default 4.1 to a higher value until the message disappears. (5.1 should probably be enough.)
b. Either use x264->Base->General Settings->Encoding mode->constant rate factor (1-pass) or a higher bitrate.
