Did you see version of stabilisation script to use central area of frame to detect motions and the whole frame to stabilize detected motions?
wid=320 hei=240 # size of rectangle area in the middle of frame to get motions
mini=last.crop((last.width-wid)/2,(last.height-hei)/2,wid,hei)
super = mini.MSuper(rfilter=2)
forward_vectors = MAnalyse(super, isb = false, truemotion=true, search = 3, delta = 1)
globalmotion = mini.MDepan(forward_vectors, thSCD1=10000)
DepanStabilize(data=globalmotion, cutoff=1.0, prev=1, next=1, subpixel=2, mirror=15, method=0, dxmax=10, dymax=40, rotmax=0, zoommax=1)
It is stabilization part of script taken from this Russian post.
MVtools2/MDepan is used instead of DepanEstimate. If it needed MSuper/MAnanlyze can be changed to SVP's SVSuper/SVAnalyze/SVConvert.
I will look to your test video. Later a little
