I finally have some settings that work well at full screen 720x480 resolutions. I switched from sharktooths matrix to mp4 guys M4G_LRM_V4 matrix because the bitrates get low enough to justify it and after few test encodes, it looks slightly better to me. I am using 941 as the max bit rate for 720x480 and the following settings.
level=40:bframes=3:ref=6ubme=6:me=umh:no-fast-pskip=1:trellis=1:cabac=0:bframes=4:vbv-maxrate=5000:vbv-bufsize=1500:analyse=all:me=umhubme=6:cqm=.\CQM\M4G_LRM_V4.cfg:nf:keyint=240:min-keyint=24:ratetol=10:mixed-refs=1:brdo=1:b-pyramid=1:8x8dct=1:partitions=all:no-psnr=1:no-ssim=1:ipratio=2.8:pbratio=2.6:aq-mode=2:aq-strength=1.0:bime=1
Cabac is off and there are several other small changes from what I am using on widescreen encodes, I also do not use the turbo first pass option for this because with it on I was getting a small amount of blocking in dark empty space.
Ive only tested these settings on a shorter clips but they seem to hold up very well compared to my other settings that need to be upscaled more. x264 blows xvid away on a large hd display imo.
