[bob0r]

When i remove the last line, another one is bad, someone just needs to make it correct, i have mailed the author as i said.

Sharktooh come irc please (ill try not fall asleep this time :o)

[MatMaul]

yes the patch is malformed but it is just a problem with the patch file itself not the code I think.

here is a good patch :

@bob0r

I would like to request your next build please use the hrd/pulldown patch with the interlacing fix from dattrax, attached in the post:
http://forum.doom9.org/showpost.php?p=1047919&postcount=157

(if that is not too much trouble)
Thanks

:thanks:

Thanks bob0r, much appreciated!

[survivant001]

why do I still obtain buffer underflows event with the vbv patch ?

[akupenguin]

VBV is aproximate. x264 will only make an effort to comply, and warn you when it failed.

[survivant001]

@akupenguin

thanks.

I'm trying to figure how to avoid this problem, or which setting to tweak whent his happen

here a discusion with other person that have the problem

[Sagittaire]

In most time you can solve this problem if you reduce qcomp.

Try with this empirical formulation:

qcomp = 1.00 - ( average_bitrate / max_bitrate )

[survivant001]

thanks Sagittaire.

here my command line (mostly base on one that you posted)
"D:\DVD-tools\tools\AutoMKV095_NORIP\exe\encoder\x264.exe" --pass 2 --bitrate 7304 --stats "D:\DVD-convertion\converting\temp\.stats" --progress --keyint 14 --min-keyint 2 --bframes 3 --qpmin 5 --qpmax 51 --mixed-refs --trellis 1 --ref 3 --filter 0,0 --subme 6 --direct auto --vbv-bufsize 14745 --vbv-maxrate 30000 --me dia --level 4.1 --weightb --b-rdo --bime --analyse p8x8,b8x8,i4x4,i8x8 --8x8dct --threads auto --thread-input --aud --nal-hrd --sar 1:1 --me-prepass --qcomp 0.40 --ipratio 1.10 --pbratio 1.10 --no-psnr --output "D:\DVD-convertion\converting\temp\movie.264" "D:\DVD-convertion\converting\temp\movie.avs" -v 2>pass_verbose.txt

by your formula, 0.40 should be ok.. but doesn't work.

I'll try with 0.35 (but don't know what will be the result on quality)
here my output log
