[mythtv-users] Encode SD to H264 via mencoder - best settings

Hi *

As subject line says, I want to encode SD (720x576 interlaced, 4-6Mb/s) 
content to non-interlaced H264. Container can be avi.

Currently I was able to achieve quite good quality with latest mencoder 
SVN & following settings (here only video part):

VIDEO_FirstPass="-ovc x264 -x264encopts 

VIDEO_SecndPass="-ovc x264 -x264encopts 

Issue is interlacing. Converted content is still interlaced. Playing it 
on VLC with deinterlace ON gives really nice picture, however with 
deinterlace OFF it has classical "interlace" distortions on fast moving 
parts :-(
As my system is default noninterlaced - I want to have sll contene as noninterlaced.

I was trying add video filters like i.e. "-vf yadif=3,mcdeint" but 
result was:
-content start to be deinterlaced
-all movements are visibly "vibrant"
-video & audio are out of sync & video is much slower

Can somebody hint me how to improve my mencoder parameters to have 
proper interlacing & keep good quality ?

Also maybe this thread might be good place to share other ppl optimal 
SD->H264 mencoder parameters...

thanx in advance
