Working on some new settings... Looks like I am getting equal quality with ~50% less skipped frames (from 77 on the previous settings to 36 on these new settings). That is my result for just one test video, so further testing needs to be done...
Settings For MeGUI (Using MeGUI Development Build v0.3.0.1010 & x264 Revision 891):
--pass 2 --bitrate ? --stats ".stats" --keyint 240 --min-keyint 24 --ref 5 --no-fast-pskip --bframes 5 --b-pyramid --b-rdo --bime --weightb --direct auto --nf --subme 7 --trellis 1 --partitions all --8x8dct --qpmin 10 --qpmax 51 --ipratio 2.8 --pbratio 2.6 --vbv-bufsize 1500 --vbv-maxrate 5000 --ratetol 10 --qcomp 0.6 --me umh --merange 16 --threads auto --thread-input --aq-mode 2 --aq-strength 1.0 --cqmfile "C:\CQM\EQM_AVC_HR.cfg" --progress --no-psnr --no-ssim --output "output" "input"
The main changes here are: "--ipratio 2.8 --pbratio 2.6 --ratetol 10 --aq-mode 2 --aq-strength 1.0 --trellis 1"... My first tests with Trellis were incorrect, and Trellis does not seem to be causing much (if any) of the skipped frames.
Some of the other settings are the default settings, but I defined them just to show you exactly what settings I was using. Please note, I am not using the "--mixed-refs" & the "--no-dct-decimate" tags. Also, I set the AVC Profile = "High Profile" & the AVC Level = "Unrestricted"... the reason for this is P4x4 macroblocks are not allowed in level 3 with B-Frames, so that means not all partitions are being looked at.
