Re: [請問] x264 vfw版本
※ 引述《tllk (天氣好熱啊)》之銘言：
: 以下是實驗，僅為研究壓縮DVD高動態的部分，沒有要盜版或去散播的意圖。
: 01的檔案是用VirtualDubMod壓出來的，是 x264 818 vfw版本
: http://www.badongo.com/vid/684235
options: cabac=1 ref=1 deblock=1:0:0 analyse=0x3:0x33 me=esa subme=7 brdo=0
^^^^^^^^^^^^^
這兩個有夠慢...
mixed_ref=0 me_range=16 chroma_me=1 trellis=1 8x8dct=1 cqm=0 deadzone=21,11
chroma_qp_offset=0 threads=3 nr=0 decimate=1 mbaff=0 bframes=0 keyint=250
keyint_min=25 scenecut=40(pre) rc=2pass bitrate=1300 ratetol=1.0
rceq='blurCplx^(1-qComp)' qcomp=0.60 qpmin=10 qpmax=51 qpstep=4 cplxblur=20.0
qblur=0.5 ip_ratio=1.40
這一個其實最慢的參數你都選了....
mixed ref 反而是0 很怪
: 02的檔案是MeGUI壓的
options: cabac=1 ref=10 deblock=1:-2:-1 analyse=0x3:0x133 me=esa subme=6
^^^^^^^ 這開太大了 應該是造成你覺得比vfw 慢的原因
me-prepass=0 brdo=1 mixed_ref=1 me_range=16 chroma_me=1 trellis=2 8x8dct=1
cqm=0 deadzone=21,11 chroma_qp_offset=0 threads=3 nr=0 decimate=0 mbaff=0
bframes=16 b_pyramid=1 b_adapt=1 b_bias=0 direct=3 wpredb=1 bime=1 keyint=250
keyint_min=25 scenecut=40(pre) rc=2pass bitrate=1300 ratetol=1.0
rceq='blurCplx^(1-qComp)' qcomp=1.00 qpmin=10 qpmax=51 qpstep=4 cplxblur=20.0
qblur=0.5 ip_ratio=1.40 pb_ratio=1.30 aq=2:1.00耊
Ref me subme 這三個嚴重影響壓制速度
我習慣是 ref=3 me=umh subme=6
不過我的電腦是四年前的 所以我只開這樣壓
