stackhorizontal( a.crop(0,0,width(a)/2,0) .subtitle("source"),
\ b.crop(width(b)/2,0,0,0) .subtitle("filter") )

How can I compare a screen from a source ( .m2ts file) with an encode one ( .mkv) ??
What are the required softs and what settings are necessary ???

How can I compare a screen from a source ( .m2ts file) with an encode one ( .mkv) ??

Two quick ways come to mind:

1) AvSPmod, drag & drop M2TS into one tab, drag & drop MKV into 2nd tab, preview both tabs & flip back and forth between tabs for differences ...

2) Avisynth script below, open with a media player that has pause & frame by frame (POTPlayer, The KMPlayer, MPC-HC, etc), compare by moving from frame to frame ...

Script:
a=DSS2("whatever.M2TS")
b=DSS2("whatever.MKV")
interleave(a,b)

Another way to visually compare 2 clips :-
place these functions at the bottom of your script, and then call one of them after your filtering, eg

comparisonBox4(a,"before",b,"after")

or maybe

comparisonBox4(a,"before",b,"after") ++ comparisonBox4(b,"after",a,"before")



Function comparisonBox2(Clip a, string asub, Clip b, string bsub) {
hClip = a.height()
wClip = a.width()
stackvertical(stackhorizontal(a.crop(0*wClip/2,0*hClip/2,-1*wClip/2,-1*hClip/2).subtitle(aSub,size=10), \
b.crop(1*wClip/2,0*hClip/2,-0*wClip/2,-1*hClip/2).subtitle(bSub,size=10)), \
stackhorizontal(b.crop(0*wClip/2,1*hClip/2,-1*wClip/2,-0*hClip/2).subtitle(bSub,size=10), \
