Closed to the source encode

[MonoS]

Hello

I want to encode DVD source using x264

I'm not interested in fast encode, device compatibility or anything else, i only want to have a backup rip of some DVDs, as closed to the source as possible

I encoded the 2 dvds of the Evangelion DTS Edition, getting very very good rips of 772MB (1441kbps) for Death(True)^2 and 1.03GB (1680kbps) for Air - magokoro Wo Kimi Ni

I tried to compare the original and the encoded one and seems that my rip is better than the original

I used this avs script

SetMemoryMax(500)
SetMTMode(3,2)
LoadPlugin("DGDecode.dll")
DGDecode_mpeg2source("filename.d2v")
QTGMC(Preset="Slow", EdiThreads=2, SourceMatch=3, MatchPreset2="Slow", Lossless=2)
SelectEven()
crop(x,y,z,k)
LanczosResize(w,h)

and this cmd for the x264 [2208JEEB High 10]

--preset placebo --tune animation --qp 31 --deblock 0:0 --keyint infinite --min-keyint 1 --open-gop \
--bframes 6 --ref 6 --qpmin 1 --ipratio 1 --pbratio 1 --merange 32 --me umh --subme 10 --output

Is this a good configuration for mine target?? Or there's a better/faster one??

Thanks in advance for attention
