小测试:测试源是MF第一话的1080 BDRip截取其中的500帧,设置参数如下:
--cqmfile "C:\AutoMKV\profiles\x264-profiles\matrix\M4G_High_Detail_V3.1.cfg" --no-fast-pskip --no-dct-decimate --mixed-refs --scenecut 40 -I 90 -i 25 --me umh --merange 32 --sar 1:1 --threads 3 -r 6 --nr 0 -f -2:-1 -b 16 --direct "auto" --bime --b-bias 0 --b-pyramid -w --deadzone-inter 4 --deadzone-intra 6 --aq-mode 0 --chroma-qp-offset 0 --direct-8x8 1 --8x8dct -A p8x8,p4x4,b8x8,i8x8,i4x4 -m 7 --b-rdo --psy-rd 1.0 --qpmin 10 --qpmax 51 --qpstep 4 --qcomp 0.900000 --ipratio 1.400000 --pbratio 1.300000 --vbv-init 0.9
两次压制均为Single Pass CRF=20
第二个加入--b-adapt 2
第一次的结果:

首次测试结果出炉。小点评:用新的这个,消耗的码率有所提升,连带的各个数字也更好看了,只是速度实在是。。。
