Hi,

I actually encode with (please excuse the line wrapping) :

-vf crop=$CROP,scale=$SCALE,hqdn3d=2:1:2,harddup -ovc x264 -x264encopts bitrate=$BR:subq=5:partitions=all:8x8dct:frameref=2:bframes=3:b_pyramid:weight_b:turbo=1:pass=1

-vf crop=$CROP,scale=$SCALE,hqdn3d=2:1:2,harddup -ovc x264 -x264encopts bitrate=$BR:subq=5:partitions=all:8x8dct:frameref=2:bframes=3:b_pyramid:weight_b:pass=2

but sometimes it's slow (especially with big scale).  Sure I can put turbo=2 etc...But I wonder
whether if it's not croping and scaling which waste time. 

Is it possible to use  libavcodec x.264 to benefit autoaspect option ?
And how to use it ? 

Thank you very much.
