Squeezing out more details on a grass pitch

[snappybane]

Hi!

I've tried and tried but it seems I have some problems squeezing out more details when the subject is a grass pitch, when using x264 compared to XviD.

First, here are some screenshots. First the 'original' (that is a hfyu sample):

Then the XviD sample:

And finally x264:

As you can see, all the above images actually sucks, but that's because of the content. Back to the subject. Even the filesize reflects the problem. x264 contains less details than xvid.

The commandline for x264:

x264 --pass 2 --bitrate 1800 --stats ".stats" --ref 3 --no-fast-pskip --bframes 3 --b-pyramid --weightb --direct auto --nf --subme 6 --trellis 1 --analyse all --8x8dct --qpmin 5 --vbv-maxrate 25000 --me umh --merange 12 --threads 2 --thread-input --cqmfile "eqm_avc_hr.cfg" --progress --output

And for xvid:
xvid_encraw.exe -i "hfyu_muha.avs" -pass2 "hfyu_muha.stats" -bitrate 1800 -kboost 100 -chigh 30 -clow 15 -overhead 0 -nopacked -vhqmode 4 -qpel -qmatrix "eqm_v3ulr_rev3.xcm" -closed_gop -lumimasking -imin 3 -imax 5 -pmin 3 -pmax 5 -bvhq -bquant_ratio 162 -bquant_offset 0 -bmin 3 -bmax 5 -threads 2 -avi "muha_xvid.avi"


I'm trying to keep a "reasonable" file size, and decided that a bitrate of 1800 obtains that. So is there anything I can tweak on the x264 that can squeeze out just a tiny bit more details?

Turn --filter down? Sharktooth likes -2,-1, but you can go even lower if it helps. For xvid, a higher eqm matrix will help - hr, perhaps, or even lr at least. On the other hand, it'll cause more ringing and possibly more blocking if the quants rise, in exchange for the extra detail.
