Combining DePanInterleave and DePanStabilize, am I doing it right?

[Chainmax]

Some time ago, I read a recommendation from scharfis_brain to Boulder of using DePanInterleave in order to improve a script, saying that it helped a lot on video stuff as it usually contains panning/zooming. I have some very crappy digicam videos I want to make something discernable out of and I thought of using DePanStabilize in addition to DePanInterleave. Is that a good idea? If so, would this:

i=ConvertToYV12()
mdata=DePanEstimate(i)
DePanStabilize(i,data=mdata)
DePanInterleave(i,data=mdata)

be the right way to call the functions or would you change the order?

[scharfis_brain]

i=ConvertToYV12()
mdata=DePanEstimate(i)
r=2 # interleaveradius
DePanInterleave(i,data=mdata,prev=r,next=r)
yourfiltershere()
selectevery(r+r+1,r)
DePanStabilize(last,data=mdata)

Code:
i=ConvertToYV12()
mdata=DePanEstimate(i)
r=2 # interleaveradius
DePanInterleave(i,data=mdata,prev=r,next=r)
yourfiltershere()
i=selectevery(r+r+1,r)
mdata=DePanEstimate(i)
DePanStabilize(i,data=mdata)

use 2-nd DePanEstimate(i) would be beter (yourfiltershere() can change clip too much)...

None of those options seem to work, in both cases variable black borders appear and change size, it's quite dizzying.
