no, i first ticked the command line option off, then i set the CRF bar to 18 in the built-in settings of x264vfw!
it produces bigger file size with the same quality as the version that comes with FU!
Edit:
wow, i encoded the exact same video with the exact same settings twice, and it produced two files with two different file sizes! one of them hangs a bit at first when you play it! the codec looks buggy to me! i'm gonna try bugmaster's build instead!
edit: it gives even bigger file size than both of them at same settings!
i don't think the build that comes with FU is crappy or outdated! just look at how long this command line is! it's brilliant! :P
"--quiet --vd-hack --crf 18 --threads 2 --ref 10 --mixed-refs --no-fast-pskip --bframes 16 --b-pyramid --b-rdo --bime --weightb --filter -2,-1 --subme 6 --trellis 2 --analyse all --8x8dct --vbv-maxrate 25000 --me umh
"
p.s.
that command gives an error on bugmaster's build as well! you sure all parameters are correct?
"--preset slow --crf 18 --filter -2,-2 --bframes 5 "Last edited by UnD3R0aTh; 3rd Mar 2010 at 11:02.

It's not really comparable, because the versions and settings are different.
The old build of x264vfw in Fairuse says "Jan 2008" and "svn736", so it's definitely highly outdated.

"--preset slow --crf 18 --filter -2,-2 --bframes 5 "
--crf 17 --subme 9 --me umh --trellis 2 --direct auto --b-adapt 2 --bframes 6 --ref 8 --deblock -2:-2 --merange 24 --rc-lookahead 60 --no-fast-pskip --analyse all
For something somewhat faster and only a bit less efficient:
--crf 17 --subme 8 --me umh --trellis 2 --direct auto --b-adapt 2 --bframes 5 --ref 6 --deblock -2:-2 --rc-lookahead 50 -
thank you, i'm gonna try that and tell you how it goes!
btw, how did you know what version comes with FU? i wasted a lot of time trying to figure that out!
Edit: arlight, it works greateven smaller file size than the one that comes with FU! (with CRF 18)
it looks like these options play a big role in the process, but since the only parameter i'm able to customize is crf, can you tweak these options for me a bit more? i want the maximum quality possible considering that slowness is not an issue(i leave it encoding at night)
i also would like to learn about these options, do you recommend a guide?
thx a lot creamyhorrorLast edited by UnD3R0aTh; 3rd Mar 2010 at 13:18.

lol, i feel stupid!
thx
anyway, there's another problem! that command line gives me oos video on a different DVD! the frame freezes for 2 seconds or so at the begging of the video but the audio plays from start!
(i tried to turn off VBR mp3, still oos, i turned off comand line and used codec settings, it's in sync)
Edit:
sorry, this command line produces oos video on any DVD, the first DVD had voice over instructions so it's hard to tell if it's out of sync!Last edited by UnD3R0aTh; 3rd Mar 2010 at 22:10.

Sounds like it may be a b-frames issue due to the problematic framework x264vfw has to work within. Try adding --vd-hack, though I have no idea if it'll work. If it doesn't, try b-frames 4 and ref frames 4. Worse come to worse, just use the defaults without the commandline.
Or just use a tool based on mainstream x264 (not x264vfw), like Handbrake. -
works like a charm with the vd hack
now again, one final request, i really need to tweak those parameters even more to achieve maximum quality and maximum compression possible (again, slowness is absolutely not an issue) btw, shouldi use AVI container or MKV container?
also, i'd appreciate if you explained this to me, why does everyone, or most of them, hate x264vfw? -
My advice never to push to the absolute limit of quality, because you'll get to the point where you double your encoding time to gain less than 1% in quality (and you can't see the difference anyway). The settings I gave are only a step or two below the absolute max settings. Those are labeled "placebo", meaning you waste a whole lot more time without seeing any visible benefit.
That said, you can refer to this old thread on Doom9 about the x264 presets & tunings system, and make tweaks appropriate for your source video based on the samples there. The main guide to x264 settings is here at MeWiki.

Most of the x264 encoding tools out there rely on x264 CLI (the mainstream version) or libx264 (a library), which have remained up-to-date all this time.Last edited by creamyhorror; 4th Mar 2010 at 03:10.
