I use -ovc x264 -x264encopts \ crf=22:trellis=1:qcomp=0.8:weight_b:8x8dct:subq=6:threads=1:nr=750 or the same with crf=23 for lower quality input and nr=500 (for clean input). That gives me for DVD MPEG2 input output of the same quality (and yes, I've looked at very difficult parts of both input and output basically "frame by frame" while finding those settings ;) Those settings give quite small files at times, esp. due to the 'nr' noise reduction filter (which makes files 20-50% smaller with no visual impact and little impact (<6%) on encoding speed. I get e.g. a mere 241MiB video track for a 41:19min series-episode in PAL (720x576@25fps progessive anamorphic (=> 1024x576) with crf=22). The MPEG2 original is 1.16GiB for the video track... For me, depending on input, above settings are the "sweet spot" regarding quality (no difference I can see, either at 1:1 or fullscreen at 1280x1024 with black bars) and file size.
