Thx *.mp4 guy for this FAQ

But I think this says it all, really :

Strength and Threshold ...
The bigger the strength (alpha), the more details you lose on each processed macrobloc ...
The bigger the threshold (beta), the more macroblocs get processed ...

Note : -6:-6 is nearly identical to turning the inloop filter off. Negative values don't sharpen the picture more than it is, they just remove less detail than the default 0:0

But obviously, throwing "return avisource("yourclip.avi").Trim(500)" into x264 and testing ourselves is the way to go

PS : if anyone wants to compare ALL the inloop settings, be prepared to do (6+1+6)² = 169 encodes. Havefun ^^
