Ok, just finish testing filter combinations to see whats the best conbination of Compression & Quality.

Optimal Script

unfilter(50,50)
temporalsmoother(1,2)
mergechroma(blur(1.58))
mergeluma(blur(0.2))

Optional Script

#STMedianFilter(10, 30, 0, 0, 10, 30)
unfilter(30,30)
FluxSmooth(3, 8)
temporalsmoother(1,2)
mergechroma(blur(0.8))
mergeluma(blur(0.2))
#Convolution3D(preset="movieLQ")
#BlockBuster(method="noise")

Filter+Frames(498)= File size

Unfilter 50= 2,265 kbs
Unfilter 25= 2,186 kbs
Unfilter 30= 2,154 kbs
Unfilter 30+Blockbuster= 2,218 kbs
Unfilter 30+FluxS.= 2,079 kbs *
Unfilter 30+Conv.LQ= 2,070 kbs *
Unfilter 30+Flux+Conv.LQ= 2,032 kbs *
Unfilter 30+STM= 2,023 kbs

like you see Unfilter 30 & MergeChroma 0.8 gave me smaller files while quality still very good (You would think that Unfilter 25 be smaller), Blockbuster increase file size a bit and STM give the best compression at the expense of Detail. After comparing I Like This*

PS: I Hope Kwag doesnt kick my ass

Why would I
That's what this whole game is all about Testing, testing testing, until we get the best parameters we like
